从ajax返回数据会导致奇怪的对象 [英] Returning data from ajax results in strange object

问题描述

我知道这个问题可能已被问了一千次，但我似乎无法找到答案。我希望 result 是从ajax-request返回的数据，它应该是一个json数据数组（ console.log的结果（数据） ））。

I know this question hast probably been asked a thousand times, but i cannot seem to find the answer. I want result to be the data returned from the ajax-request, which should be a json-data array (the result of console.log(data)).

  var result = $.ajax({
    type: 'GET',
    url: dataPath,
    dataType: 'json',
    success: function(data) {
      console.log(data)
      },
    error: function(){
      //alert("damn");  
      },
    data: {},
    aync: false
  });

  console.log(result); 

然而， console.log（结果）; 将返回一些奇怪的物体，我不知道如何处理。为什么不是结果 = 数据？

However, console.log(result); will return some strange object, which I don't know how to handle. Why isn't result = data ?

推荐答案

首先从代码中删除 aync：false 。它应该拼写 async：false 但你不需要它来实现你的目标，它实际上做的是阻止整个浏览器的用户界面，导致糟糕的用户体验。请记住，AJAX中的A表示异步。

First of all remove the aync: false from your code. It should be spelled async: false but you don't need it to achieve your goal and what it actually does is block the entire browser's user interface resulting in a terrible user experience. Remember that "A" in AJAX means Asynchronous.

$。ajax（）来电是承诺，这与您的数据不同，但它仍然可用于获取您的数据。您只需要以某种方式使用它。

The result of an $.ajax() call is a promise which is not the same as your data, but it can still be useful to get to your data. You just need to use it in a certain way.

尝试更改：

 console.log(result);

to：

result.done(function (data) { 
    console.log(data);
});

或：

result.done(function (data) { 
    console.dir(data);
});

甚至可能有效 - 未经测试：

or even this might work - untested:

result.done(console.dir);
