如何将值传递给jQuery Ajax成功处理程序 [英] how to pass a value to jQuery Ajax success-handler

问题描述

在jQuery中提供以下Ajax调用:

Give the following Ajax call in jQuery:

  {
  .
  .
  .
  ,
  getSomeData: function(args, myUrl, foo) {
        $.ajax( {
        type: "GET",
        url:  myUrl,
        data: args,
        async: true,
        dataType: 'json',
        success: myHandler  

         });
 },

   myHandler: function (data, textStatus, oHTTP, foo){   ...   }  

};

可以将值foo附加到传递给成功处理程序myHandler的参数上吗?是否有任何方法可以将值传递给GET上的服务器，并使该值以往返方式返回给客户端，并再次出现在成功处理程序的参数列表中?我无法更改data中返回的内容的结构.

Can value foo be somehow appended to the arguments that are passed to success-handler myHandler? Is there any way to pass a value up to the server on the GET, and have that value come back to the client in a round-trip, reappearing in the success-handler's arguments list? I cannot change the structure of what is returned in data.

推荐答案

如果在请求中声明myHandler，则可以使用

If you declare myHandler within the request, you can use a closure.

getSomeData: function(args, myUrl, foo) {
        $.ajax( {
        type: "GET",
        url:  myUrl,
        data: args,
        async: true,
        dataType: 'json',
        success: function (data, textStatus, oHTTP){   ...   }  

         });
 },

这样，在success回调中可以使用foo.

this way, foo will be available to you inside the success callback.
