Why?

创造sco.js的起因是为了增强Bootstrap中现有的js组件，并且也为了满足我自己所做的项目的特定需求。 对于一般的使用而言，Bootstrap中的js插件非常棒，但是，一旦你有深层次的或特定需求的时候，他们就无法满足了。 大部分的Bootstrap js插件是（或者说，在我创造自己版本的插件前）无法扩展的，并且，我所面临的问题不仅仅是写一两行代码就能解决的。这并不是说Bootstrap和它的js组件很差劲！Bootstrap的确是一个非常好的快速开发框架，但是，你不能强求让他适应所有需求。在我的使用经历中，Bootstrap的确满足了大部分需求 ：）

你的收获

sco.js中的插件可以和Bootstrap一起使用，也可以单独使用。而且，sco.js中还包含了Bootstrap中没有的插件。所有插件都进行了单元测试，并且有生产环境的使用案例。每个插件都可以通过data-attributes data-trigger="pluginName" 或者 js代码 var $modal = $.scojs_modal({...})的方式使用。 E每个插件都有“创建原因”（看下面具体说明） -- 它为了实现什么目的、它和Bootstrap中的插件有何不同、我为什么首先创建它。

大部分的css都来源于Bootstrap。我也尽量遵循Bootstrap文档，遵循Bootstrap中的格式和约定，因此，你在使用的时候不会感觉和Bootstrap有很大不同。

如果data属性可以出发某个插件，代码将是：data-trigger="plugin name"，以确保不和Bootstrap中的data-toggle="plugin name"产生冲突。 这样你就可以同时或交叉使用Bootstrap和sco.js。

接下来？

• Like mentioned in the note above, one of the priorities is to get css transition support working wherever possible.
• Carousel is coming too, based on panes.
• Ajax support for panes (and automatically for tab and carousel) - you should be able to load remote content into a pane or more slides into a carousel.
• Add predelay to tooltip - for when you might want the tooltip to appear after a bit of delay.
• form 校验对ARIA的支持。
• 如果足够有用，我将更新form校验，让他支持data-*属性，并且让他更易扩展，当然，现在还不着急。
• 你有其他建议吗？

What?

modal的主要用途是加载内容（通过ajax加载）并显示在一个覆盖层内，置于当前页面之上。当然，他还可以展示本地内容，这种使用方式不多。

Why?

由于Bootstrap中的modal不支持加载远程内容，因此就建造了这个插件。还有，我不希望在使用modal的时候将modal的内容/HTML放入当前页面，这样会让整个页面乱糟糟的。只须一个链接就能让Sco.js中的modal组件运作起来。

例如，我们有一个旅馆的网站，每个房间都有一个订房表单，与其为每个页面放入相同的表单代码，还不如将这个表单单独做成一个页面，例如"my-booking-form.html"，然后每次调用modal时就用ajax加载 href="my-booking-form.html" ，这样就能让页面的主要内容干净且对seo友好。

依赖

The modal does not depend on other libraries (other than jQuery, of course). However, we recommend you load spin.js. If spin.js is found, a spinning wheel is displayed during the loading of remote content.

案例

<!-- Button to trigger modal -->
<a data-trigger="modal" href="lipsum.html" data-title="Modal title" class="btn">Launch demo modal</a>

You don't need to worry about providing any HTML structure to the modal, this is done automatically for you. The default markup is listed in the Options section and the css comes from bootstrap. All you need to provide is the modal title and the url to the remote content. However, if you need to specify your own HTML markup check the target option.

用法

通过data属性（data-api）

Look ma', no js code:

<button type="button" data-trigger="modal">Launch modal</button>

All plugin options are available to use as data attributes. The data-api usage is "live" - meaning that you don't have to rebind new elements. Every new element having a data-trigger="modal" attribute that is added to the dom after the initial load will work out of the box.

作为jquery插件使用

$('#trigger').scojs_modal(options);

$('.modal_triggers').scojs_modal(options);

If the trigger element has data- attributes and you pass options as well, the data attributes overwrite the options with the same name.

This part is quite different from bootstrap's implementation. In bootstrap, the selected element should be the modal (meaning the modal HTML should already exist in the dom). It also means the modal HTML cannot be reused by other modals (i.e. if you want more modals on the page, each has to have its own id/html code).
In our case, the selected element is the trigger of the modal (what you click on to launch the modal) and the modal is built based on the trigger's options. You definitely have the option to use different modals but, by default, the same modal HTML is reused by every modal instance on the page. This decision was made because we found out that we never wanted more modals appearing on the page at the same time. So reusing the same modal HTML for every triggered modal seemed quite logical.

访问插件的对象实例

var modal = $.scojs_modal(options);

This gives you access to the created javascript object. Note that when you launch the modal this way, it's not shown by default. You'll have to call modal.show() at a later time to show the modal.

参数

可以通过data属性或者JavaScript代码传递参数。对于data属性，将参数名添加到data-之后，例如data-keyboard="1".

<div class="modal fade" id="modal">
  <div class="modal-header">
    <a class="close" href="#" data-dismiss="modal">×</a>
    <h3> </h3>
  </div>
  <div class="inner"></div>
</div>

$('#trigger').scojs_modal({content: 'Lorem ipsum...'});

$('#trigger').scojs_modal({content: $('#other').html()});

方法

.scojs_modal(options)

$('#trigger').scojs_modal({
  title: 'Modals are cool',
  content: "No, they're not"
});

There are no other methods available in data-api or jQuery mode yet. The following methods are available in when you get access to the js object:

.show()

Shows the modal.

var modal = $.scojs_modal({
  keyboard: true
});
modal.show();

.close()

Closes the modal.

var modal = $.scojs_modal({
  keyboard: true
});
modal.show();
modal.close();

.destroy()

Closes and destroys the modal, removes all modal HTML and events from the DOM.

var modal = $.scojs_modal({
  keyboard: true
});
modal.show();
modal.destroy();

What?

A specialised modal that has a yes/no button in the footer. The yes is attached to some action, the no dismisses the modal without doing anything else. Basically a glorified alert().

Why?

We wanted an easy way to make the user confirm some action like deleting something from their profiles.

依赖

The confirm plugin depends on the modal. Make sure you load both when you want to use confirm.

案例

<!-- Button to trigger confirm -->
<a data-trigger="confirm" href="/delete/me" class="btn">Launch demo confirm</a>

用法

通过data属性（data-api）

<a href="/link-to-go-to/when-user-presses-yes" data-trigger="confirm">Launch confirm</button>

All modal options are available for confirm as well though some might not make much sense (like loading remote content). There are some extra options available for confirm, see the options below.

作为jquery插件使用

$('#confirm_trigger').scojs_confirm(options);

Like with the modal, you call scojs_confirm() on the trigger, not on the modal element itself. And, if data- attributes exist, they overwrite any general options you pass to the plugin.

访问插件的对象实例

var confirm = $.scojs_confirm(options);

This gives you access to the created javascript object. Note that when you launch the confirm this way, it's not shown by default. You'll have to call confirm.show() at a later time to show the confirm modal.

参数

可以通过data属性或者JavaScript代码传递参数。对于data属性，将参数名添加到data-之后，例如data-keyboard="1".

All modal options are available for confirm as well. Note, however, that the default confirm modal doesn't have a title so setting title has no effect. You can, of course, have your own confirm modal with a title in which case this option will work as expected. There are also some modal options that don't make much sense to be set for confirm like remote and cache but you're free to use them if you need them.

There are some extra options available for confirm or options that have a different default than the modal. See below:

<div class="modal fade confirm_modal" id="confirm_modal">
  <div class="modal-body inner"></div>
  <div class="modal-footer">
    <a class="btn cancel" href="#" data-dismiss="modal">cancel</a>
    <a href="#" class="btn btn-danger" data-action="1">yes</a>
  </div>
</div>

<a data-trigger="confirm" href="/delete/me" class="btn">Delete</a>
<button class="btn" data-action="/delete/me" data-trigger="confirm">Delete</button>

方法

.scojs_confirm(options)

$('#trigger').scojs_confirm({
  content: "Ain't that cute?",
  action: "https://google.com"
});

var confirm = $.scojs_confirm({
  content: "Oh, noes, you really want to delete me?",
  action: function() {
    this.close();
  }
});
confirm.show();

All modal methods are available for the confirm as well.

What?

Accordions or show/hide togglers.

Why?

So much markup in bootstrap for their collapse component! And IDs. I hate IDs! While IDs give you a great degree of freedom in what to target (as in I want this button to collapse this far away block across the page), most of the time it's not how an accordion works. You usually want to click on a menu link and expand the block under/above that link. So I made this collapse plugin to address the said issues.

依赖

The collapse does not depend on other libraries (other than jQuery, of course).

案例

In its most basic form, the collapser plugin is nothing more than a simple on/off toggler for another block element. All you need to get started is a trigger with a data-trigger="collapse" attribute and a div inmediately following the trigger with a class of .collapsible. You will probably want that div to be set to display:none (eg. via the bootstrap helper class .hide or with style="display:none").

<a href="#" data-trigger="collapse">Click for default behaviour</a>
<div class="collapsible hide">
  Lorem ipsum...
</div>

更多案例：

Let's spice things up a bit: the accordion behaviour. In this mode, we need to tell each trigger what html element is the parent for the whole accordion:

<div class="sidenav">
  <a href="#" data-trigger="collapse" data-parent=".sidenav" class="active">Menu 1</a>
  <div class="collapsible">
    The quick brown fox jumps over the lazy dog.
  </div>
  <a href="#" data-trigger="collapse" data-parent=".sidenav">Menu 2</a>
  <div class="collapsible" style="display: none">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit.
  </div>
</div>

We can make this even more interesting by adding a "show more / show less" toggle:

<div>Lorem ipsum...</div>
<div class="collapsible hide">Etiam lacinia...</div>
<a href="#" class="show_more_example">show more</a>

<div>Q: What does the quick brown fox do?</div>
<div class="collapsible hide">A: The quick brown fox jumps over the lazy dog.</div>
<a href="#" class="show_more_example">show more</a>
<script>
  $(document).on('click', '.show_more_example', function(e) {
    $(this).scojs_collapse({
      triggerHtml: {on: 'show less', off: 'show more'}
      ,mode: 'prev'
    });
    return false;
  });
</script>

用法

通过data属性（data-api）

<button data-trigger="collapse" class="btn">Click me</button>

The data-api usage is "live" - meaning that you don't have to rebind new elements. Every new element having a data-trigger="collapse" attribute that is added to the dom after the initial load will work out of the box.

作为jquery插件使用

$('#collapse_trigger').scojs_collapse(options);

If data- attributes exist, they overwrite any general options you pass to the plugin.

When you call the plugin this way, all it does is toggle the target. To toggle it back you'd call the plugin again. However, it's best used inside a click event (or hover/etc) like this:

<script>
  $(document).on('click', '.collapse_triggers', function(e) {
    $(this).scojs_collapse(options);
    return false;
  });
</script>

访问插件的对象实例

var collapse = $.scojs_collapse(options);

This gives you access to the created javascript object. Note that when you launch the collapse this way, it doesn't toggle the target by default. You'll have to call collapse.toggle() at a later time, as many times as you want, to toggle the target on/off.

参数

可以通过data属性或者JavaScript代码传递参数。对于data属性，将参数名添加到data-之后，例如data-parent=".foo".

方法

.scojs_collapse(options)

$('#trigger').scojs_collapse({
  parent: '#sidebar',
  mode: 'prev'
});

There are no other methods available in data-api or jQuery mode yet. The following methods are available when you get access to the js object:

.toggle()

Toggles the target element.

var collapse = $.scojs_collapse();
collapse.toggle();

What?

Tab functionality for your pages.

Why?

Like with the other plugins that already exist in bootstrap that I chose to rewrite, my main problem with bootstrap tabs is the complexity of the markup required and the heavy use of IDs. Sco.js tabs are simpler, have some sane defaults but the simplicity comes with a price: it doesn't support dropdown tabs for example. If you need the extra complexity, by all means, use bootstrap tabs.

依赖

Panes - because it's the core of the tabs and carousel. If you want history support you should also include jQuery Address. See below for how to use it.

案例

To start using the tab plugin you need an <ul data-trigger="tab"> for the tab headers and a <div class="pane-wrapper"> immediately following the ul for the tab content. There should be as many li's in the ul as children elements in the .pane-wrapper div. A click on the first tab header would select the first .pane-wrapper child, a click on the nth tab header would select the nth child.

The links in the tab headers don't need a specific href attribute, unless you want history support:

<ul class="nav nav-tabs" data-trigger="tab">
  <li><a href="#">Tab 1</a></li>
  <li><a href="#">Tab 2</a></li>
  <li><a href="#">Tab 3</a></li>
  <li><a href="#">Tab 4</a></li>
</ul>
<div class="pane-wrapper">
  <div>...</div>
  <div>...</div>
  <div>...</div>
  <div>...</div>
</div>

Browser history support

To enable history support for tabs make sure you load jQuery Address and that the links in your tab headers have anchor hrefs (e.g <a href="#foo">Tab 1</a>).
However, the hrefs must NOT point to any element on the page (there should be no element with that ID on the page). The history support is bidirectional:

• when you click on a tab header that has an anchor href the hash gets added to the current url. This is the easy direction :)
• when you add the hash of a tab header to the url, the tab switches to that pane

If there's an element that has the same ID as one of your hrefs, the tabs will still function properly but the page will "jump" to that element, as anchors are supposed to work in browser.

Click on the tabs above and see how the hash is added to the page url (which is normal browser behaviour) and try adding #tab1 or #tab2 or #tab3 to this page url manually and see how the tabs change. You can also click on the last tab header - the proper pane will be selected but the page will jump up to modals.

用法

通过data属性（data-api）

See the examples above for how you can use this with the data-api. You need to add data-trigger="tab" to the element wrapping the tab headers.

The data-api usage is NOT "live", unfortunately. If you add elements to the DOM having a data-trigger="tab" attribute, you will have to also bind that new element yourself using javascript.

作为jquery插件使用

$('#mytabs').scojs_tab(options);

If the #mytabs element has data- attributes and you pass options as well, the data attributes overwrite the options with the same name.

访问插件的对象实例

var tab = $.scojs_tab('#mytabs', options);

参数

可以通过data属性或者JavaScript代码传递参数。对于data属性，将参数名添加到data-之后，例如data-content="#foo".

方法

.select(index)

Select the index-th element (0-based).

var $tab = $.scojs_tab('#foo');
$tab.select(1);

What?

Y'know...tooltips. The kind of dialog baloon that usually appears on hover over stuff.

Why?

While other tooltip plugins focus on pixel perfect positioning, the main focus of Sco.js tooltips plugin is to keep the actual tooltip in the viewport at all times. It's not so much about perfect positioning but about making sure that it's fully shown in the view area when you hover over elements with tooltips, even over those that are positioned near edges of the viewport.

依赖

jQuery.

案例

<a href="#" data-trigger="tooltip" data-content="Lorem ipsum dolor">Hover me</a>

Scroll the page up till the example link above is at the very top of the page and hover over the link again - you will see the tooltip appearing below the link. Try the same with left/right/bottom - the tooltip will reposition itself to stay on page all the time.

用法

通过data属性（data-api）

<div data-trigger="tooltip" data-content-elem="#tooltip_element">Hover me</div>

The data-api usage is "live" - meaning that you don't have to rebind new elements. Every new element having a data-trigger="tooltip" attribute that is added to the dom after the initial load will work out of the box.

作为jquery插件使用

$('.tooltips').scojs_tooltip(options);

If the trigger element has data- attributes and you pass options as well, the data attributes overwrite the options with the same name.

访问插件的对象实例

var tooltip = $.scojs_tooltip('#trigger', options);

This gives you access to the created javascript object. Note that when you launch the tooltip this way, it's not shown by default. You'll have to call tooltip.show() at a later time to show the tooltip.

参数

可以通过data属性或者JavaScript代码传递参数。对于data属性，将参数名添加到data-之后，例如data-content="my content".

方法

.scojs_tooltip(options)

$('#trigger').scojs_tooltip({
  content: "Tooltip content"
  ,cssclass: 'pretty'
  ,delay: 1000
});

The following methods are available when you get access to the js object:

.show()

Shows the tooltip straight away.

var tooltip = $.scojs_tooltip('#trigger', {
  target: '#foo'
  ,content: 'tooltip content'
});
tooltip.show();

.hide()

Hides the tooltip straight away.

var tooltip = $.scojs_tooltip('#trigger', {
  target: '#foo'
  ,content: 'tooltip content'
});
tooltip.show();
tooltip.hide();

.do_mouseenter()

See .do_mouseleave()

.do_mouseleave()

Useful when you have the delay option set and you don't want to hide the tooltip right away but instead hide it after the set delay. Basically, this simulates the mouse leaving the trigger. Also, this gives a chance to the user to hover over the trigger again and keep the tooltip open some more.

var tooltip = $.scojs_tooltip('#trigger', {
  ,delay: 1000
});
tooltip.show();
tooltip.do_mouseleave();  // hides after 1000 seconds

What?

This is a "flash message" - a message that appears at the top of the page and disappears after a few seconds. It can be an info or an error message.

Why?

Useful after some user action (like submitting a form for example) to let them know your app processed the action ok or there was an error.

依赖

jQuery.

案例

<a id="message_trigger_ok" href="#">Click to see the info message</a>
<a id="message_trigger_err" href="#">Click to see the error message</a>
<script>
  $('#message_trigger_ok').on('click', function(e) {
    e.preventDefault();
    $.scojs_message('This is an info message', $.scojs_message.TYPE_OK);
  });
  $('#message_trigger_err').on('click', function(e) {
    e.preventDefault();
    $.scojs_message('This is an error message', $.scojs_message.TYPE_ERROR);
    });
</script>

用法

作为jquery插件使用

$.scojs_message(message, type);

参数

What?

Valid is a javascript form validation plugin. Basically, you give it a set of rules for a form's fields and it'll either submit the form if all rules pass or show error messages if not.

Valid is the most complex and most opinionated plugin of all sco.js plugins. It also makes extensive use of other plugins (from sco.js and 3rd party) so make sure you load its dependencies before using it. It is loosely based on the jQuery form validation plugin.

Why?

There are a couple of good form validators out there. I built this one because:

• I needed support for general error messages (i.e. not related to a certain field), besides field-related messages.
• I needed support for client side validation, as well as server side validation that would pass the errors to the client for display (for example when a field would pass the "must be an email" client-side rule but it won't pass the "email already exists" server-side rule).
• I wanted support for the JSend format - to pass instructions/messages from the backend to the front end in a standard format.
• Since I was using the Kohana php framework on the backend, I wanted the validation rules defined there to work transparently on the frontend as well.
• As much I would have wanted to use the browser form validation API, they were too limited, not translatable and not customizable.

依赖

Message to display general messages, jQuery Form Plugin to submit the form via ajax. It uses the JSend specification to receive instructions from the backend. It does not depend on Modal but it knows how to close the modal window if instructed to do so by the backend. The defaults of the plugin are based on the excellent Mosto css framework for forms but you can, of course, customize it to work with any framework.

案例

<form action="valid.json" id="valid_form" class="form-horizontal">
  <label><div>Email</div> <input type="email" name="email"></label>
  <label><div>Password</div> <input type="password" name="pass"></label>
  <label><div>Password again</div> <input type="password" name="pass2"></label>
  <button type="submit" class="btn">Try</button>
</form>
<script>
  $(function() {
    $('#valid_form').scojs_valid({rules: {email: ['not_empty', 'email'], pass: ['not_empty', {'min_length': 4}], pass2: [{matches: 'pass'}]}});
  });
</script>

用法

通过data属性（data-api）

No data attributes support yet but this is something I plan on having eventually. Patches are welcome!

作为jquery插件使用

$('#form').scojs_valid({rules: options, messages: options});

访问插件的对象实例

var valid = $.scojs_valid(formId, options);

This gives you access to the created javascript object. You will have to call the object's methods on your own to trigger validation. Normally, this is all wrapped in the jQuery plugin but if you want custom functionality or you don't want to depend on the jQuery form plugin, this is the way to do it. You'll probably want to call .validate() on the js object before submitting the form and handle the JSend response from the server later on.
formId can be either a string selector or a jQuery object.
options should be an object with rules and (optional) messages: {rules: {...}, messages: {...}}

参数

{email: ['not_empty', 'email'], name: ['not_empty', {equals: 'john'}]}

$('#form').scojs_valid({
   rules: {...}
  ,onSuccess: function(response, validator, $form) {...}
});

$('#form').scojs_valid({
   rules: {...}
  ,onError: function(response, validator, $form) {...}
});

$('#form').scojs_valid({
   rules: {...}
  ,onFail: function(response, validator, $form) {...}
});

Rules

Messages

The default messages used by the plugin, when no custom message is set. Note that any occurence of the string :value in the message is replaced by the rule constraint value.

Communicate with the backend

Once the client side validation has passed, the form is submitted to the backend where you should have another round of validation. The backend can then tell the client what to do next: show some more errors, go to another page, show a Message and so on.
The instructions from backend to frontend are sent as json, in the JSend format.

案例:
{"status":"success","data":{"next":"https://google.com"}}
{"status":"fail","data":{"errors":{"email":"This error comes from server side"}}}
{"status":"error","message":"The server made a boo boo"}

方法

.validate()

Performs the client side validation and show the errors on the form fields, if any. Returns true if all rules pass and false otherwise.

var valid = $.scojs_valid('#signup_form', {rules: {email: ['not_empty']}});
valid.validate();

What?

Panes is the core for tabs and carousels. Not meant to be used standalone, unless you want to provide functionality not covered by Tab and Carousel.

It provides the basic functionality to switch between a collection of elements - show one of them then hide that and show some other. Its aim is to be easily extensible - add any kind of transition effect you want, add callbacks, etc.
By default it comes with 3 transitions ( xfade, slide, flip ) but you can add as many as you want.

Why?

Tabs and carousels are basically the same thing (from a functional point of view): A collection of elements of which only one is visible at a time. You switch between the elements by clicking on tab headers or on navigation pills. Carousels are a bit more advanced than this but the core functionality is the same. It made sense to have a library to provide the common functionality for both. You can even think beyond just tabs and carousels - how about a pagination module that switches between pages (e.g. « 1 2 3...10 »)? Or a side menu that shows various pages with a nice transition between the pages? This pattern is quite used on the web.

依赖

If you want to use transitions you need to load bootstrap-transition.js before this.

var $panes = $.scojs_panes('#foo', {active: 1});
$panes.select(0);

.prev()

Select the previous element. If the first element is active, prev() selects the last one. Returns true if the element was selected or false if not (selection might be blocked by the onBeforeSelect callback).

var $panes = $.scojs_panes('#foo', {active: 1});
$panes.prev();

.next()

Select the next element. If the last element is active, next() selects the first one. Returns true if the element was selected or false if not (selection might be blocked by the onBeforeSelect callback).

var $panes = $.scojs_panes('#foo');
$panes.next();

What?

This is really just a convenient utility function that makes links load remote content with AJAX inside some target element on the page. This behaviour is also known as "ajaxification of links". Could be used for a side menu - all menu links would load just the page content, without a full page reload.

Note that this function doesn't parse the output to display just a part of it in page and it doesn't make use of the browser history API. If you need such a full ajaxification plugin take a look at History.js.

Why?

I needed some links to load their contents with ajax but not all. There was no need for browser history API support or anything fancy.

依赖

Ajax does not depend on other libraries (other than jQuery, of course). However, we recommend you load spin.js. If spin.js is found, a spinning wheel is displayed during the loading of remote content.
