将对象数据传递给jQuery。职位的继任者函数

I want this.item of an instance of the class to be filled by the data received through jQuery.post successor function. I am able to do this using some another user-defined function to set this.item with the data received.

我想要这个。通过jQuery接收的数据填充类的实例。职位的继任者函数。我可以使用另一个用户定义函数来设置这个。项目与收到的数据。

Question : Is there any way to set this.item inside the successor function of jQuer.post() without using any other user-defined functions ?

有什么方法可以设置这个吗?在jQuer.post()的继承函数中，不使用任何其他用户定义函数?

Following is the code snippet

下面是代码片段。

Inside Class Prototype function :-

内部类原型功能:-。

   this.item = new Array();

   jQuery.post("index.php?p=getdataitem", fileobj,function(item_str_data)
              {
        ...
        this.item = ....;   
                ...

You can do

你可以做

 this.item = new Array();
var instance = this;

   jQuery.post("index.php?p=getdataitem", fileobj,function(item_str_data)
              {
        ...
        instance.item = ....;   
                ...
              }
   );

OR

或

 this.item = new Array();

   jQuery.ajax(
         {url: "index.php?p=getdataitem", 
          context: this,
          success: function(item_str_data)
              {
                ...
                this.item = ....;   
                ...
              }
         }
   );

Try this:

试试这个:

  var that = this;
  var that.item = [];

  function() {

      jQuery.post("index.php?p=getdataitem", fileobj,function(item_str_data) {
        ...
        that.item = ....;   
        ...
      });

   }();

Because of the closure, the this reference we copy (that) should be available to the inner function of the post.

由于关闭，我们复制的这个引用应该可以用于post的内部功能。
