Example

用于使用 callbacks.fire() 已传递的任何参数来调用列表中的回调:

// a sample logging function to be added to a callbacks list
var foo = function( value ) {
  console.log( "foo:" + value );
}
 
var callbacks = $.Callbacks();
 
// add the function "foo" to the list
callbacks.add( foo );
 
// fire the items on the list
callbacks.fire( "hello" ); // outputs: "foo: hello"
callbacks.fire( "world" ); // outputs: "foo: world"
 
// add another function to the list
var bar = function( value ){
    console.log( "bar:" + value );
}
 
// add this function to the list
callbacks.add( bar );
 
// fire the items on the list again
callbacks.fire( "hello again" );
// outputs:
// "foo: hello again"
// "bar: hello again"
