使用 callbacks.disable() 禁用回调列表：

jQuery 代码:

// a sample logging function to be added to a callbacks list
var foo = function( value ){
    console.log( value );
}
var callbacks = $.Callbacks();
// add the above function to the list
callbacks.add( foo );
// fire the items on the list
callbacks.fire( 'foo' ); // outputs: foo
// disable further calls being possible
callbacks.disable();
// attempt to fire with 'foobar' as an argument
callbacks.fire( 'foobar' ); // foobar isn't output
