jQuery 循环从 AJAX 成功的 JSON 结果?

2022-01-31 00:00:00 json jquery ajax

在 jQuery AJAX 成功回调中，我想循环遍历对象的结果.这是响应在 Firebug 中的外观示例.

On the jQuery AJAX success callback I want to loop over the results of the object. This is an example of how the response looks in Firebug.

[
 {"TEST1":45,"TEST2":23,"TEST3":"DATA1"},
 {"TEST1":46,"TEST2":24,"TEST3":"DATA2"},
 {"TEST1":47,"TEST2":25,"TEST3":"DATA3"}
]

如何遍历结果以便可以访问每个元素?我尝试过类似下面的方法，但这似乎不起作用.

How can I loop over the results so that I would have access to each of the elements? I have tried something like below but this does not seem to be working.

jQuery.each(data, function(index, itemData) {
  // itemData.TEST1
  // itemData.TEST2
  // itemData.TEST3
});

推荐答案

可以去掉外层循环，将this替换成data.data:

you can remove the outer loop and replace this with data.data:

$.each(data.data, function(k, v) {
    /// do stuff
});

你很亲密:

$.each(data, function() {
  $.each(this, function(k, v) {
    /// do stuff
  });
});

您有一个对象/映射数组，因此外部循环会遍历这些对象/映射.内部循环遍历每个对象元素的属性.

You have an array of objects/maps so the outer loop iterates over those. The inner loop iterates over the properties on each object element.
