jQuery插件：调用回调方法,然后可以根据响应调用插件函数

(function($)
{
   function MyPlugin(el,options)
   {
     this.element = $(el);
     this.myInput = false;
     this.options = $.extend(
     {
       onSave:function(){}
     },options);
     this.initialize();
   }

   $.fn.myPlugin = function(options)
   {
      var control = new MyPlugin(this.get(0),options);
      return control;
   };

   MyPlugin.prototype = 
   {
     initialize:function()
     {
       var me = this;
       //specifics shouldn't really matter
       //it creates some HTML to go inside the element
       //within that HTML is an input,which I can successfully invoke keyup:
       me.myInput.keyup(function(event)
       {
         if(keyPressIsEnter(event)
           me.saveFunction();
       });
     },saveFunction:function()
     {
       var value = this.myInput.val();
       this.options.onSave(value);

       //CURRENTLY I CALL succesS ANIMATION
       successAnimation();
     },successAnimation:function()
     {
        //do something to the markup within element for success
     },failureAnimation:function()
     {
        //do something to the markup within element for failure
     }         
   };
})(jQuery);

并且假设我有一个div并将其设置为使用我的插件,如下所示：

$("myDiv").myPlugin({onSave:function(value){myAjaxSaveFunction(value);});

通过此设置,插件,保存功能和动画都可以正常工作(假设从未出现过错误).但是,myAjaxSaveFunction是异步的,可能会返回成功或失败.我目前在插件中有保存功能,调用成功动画.如果我让myAjaxSaveFunction返回一个true / false,我可以(理论上)在插件中使用该返回值来确定是运行成功还是失败,但是如果@L_674_13@是异步的话则不行.

那么,这种情况通常如何处理？为了重用,我需要能够自定义处理数据的@L_674_13@作为可选的回调,但我需要插件等待它是否根据@L_674_13@的结果运行成功/失败动画(可能是异步的,或者可能不是).

@Kevin B：你在暗示这个吗？

saveFunction:function()
 {
   var value = this.myInput.val();
   var success = this.options.onSave(value);
   if(success)
      successAnimation();
   else
      failureAnimation();
 },

当this.options.onSave@L_674_13@执行时,这不会直接落入if语句吗？
