回调列表中添加一个回调或回调的集合。
一个函数,或者一个函数数组用来添加到回调列表。 .
使用 callbacks.add() 添加新的回调到回调列表:
// a sample logging function to be added to a callbacks list var foo = function( value ){ console.log( 'foo:' + value ); } // another function to also be added to the list var bar = function( value ){ console.log( 'bar:' + 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' // add the function 'bar' to the list callbacks.add( bar ); // fire the items on the list again callbacks.fire( 'world' ); // outputs: // 'foo: world' // 'bar: world'
