在 Prototype 中嵌套 Ajax 调用

我需要进行两个 Ajax 调用，其中一个调用取决于前一个调用的返回值。我尝试从外部对象的 onComplete 函数中创建一个新的 Ajax 对象，但似乎永远不会调用它。

正在调用外部对象的 onComplete 函数。代码执行到我构造第二个 Ajax 对象的位置。

它看起来像这样：

function called_from_page() {
  new Ajax.Request(
    '/request_url',
    { method: 'post', parameters: '', onComplete: function(originalRequest) {
      if (originalRequest.responseText == '0') {
         // do something
      } else {
         call_next_ajax();
      }
    }});
 }

 function call_next_ajax() {
    new Ajax.Request(
       '/next_request_url',
       { method: 'post', parameters: '', onComplete: some_other_function });
  }

所以，问题是， call_next_ajax 正在被调用，但其中的 ajax 请求没有被调用。

I need to make two Ajax calls, one dependent on the return value of the previous call. I've attempted to create a new Ajax object from within the onComplete function of the outer object, however it seems that this never gets called.

The onComplete function of the outer object is being called. Code is executed up to where I construct the second Ajax object.

It looks something like this:

function called_from_page() {
  new Ajax.Request(
    '/request_url',
    { method: 'post', parameters: '', onComplete: function(originalRequest) {
      if (originalRequest.responseText == '0') {
         // do something
      } else {
         call_next_ajax();
      }
    }});
 }

 function call_next_ajax() {
    new Ajax.Request(
       '/next_request_url',
       { method: 'post', parameters: '', onComplete: some_other_function });
  }

So, the problem is, that call_next_ajax is being called, but the ajax request within it is not being called.
