jQuery event.stopPropagation() 方法

实例

阻止 click 事件冒泡到父元素：

$("span").click(function(event){
 event.stopPropagation();
 alert("The span element was clicked.");
});
 $("p").click(function(event){
 alert("The p element was clicked.");
 });
$("div").click(function(){
 alert("The div element was clicked.");
});
