jQuery ajax成功后循环JSON响应

Loop JSON response after ajax success

提问by coder

Sorry this is a duplicate from hereasked in SO but I'm new to this so I would like to know how to do it?

对不起，这是从这里问到的重复，但我是新手，所以我想知道怎么做？

This is my ajax call:

这是我的ajax调用：

  $("#btnprocess").click(function () {
                $.ajax({
                    type: "POST",
                    url: "Default.aspx/GetFilenames",
                    data: "{}",
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function (response) {
                        alert(response.d[0]);
                        alert(response.d[1]);
                      }
                });
  });

Individually I'm able to get the response but I need to loop them.

单独我能够得到响应，但我需要循环它们。

Can anyone say me how do I do this?

谁能告诉我我该怎么做？

Use $.each().

使用$.each().

$.each(response.d, function(key, value) {
    //For example
    console.log(key + value)
})

Look hereto learn about it. (EDIT: Or here- it's a video tutorial if you prefer that.)

看这里了解它。（编辑：或者在这里- 如果您愿意，这是一个视频教程。）

if response.dis an array you could place it in a for loop like so:

ifresponse.d是一个数组，您可以将它放在 for 循环中，如下所示：

for ( var i = 0; i < response.d.length; i++ ) {
    // do action here
}

This method is preferred over the jQuery $.each()function due to its speedier nature. Check out this Fiddlefor a comparison of forvs $.each().

$.each()由于其速度更快，此方法优于 jQuery函数。查看这个Fiddle比较forvs $.each().

You could do;

你可以这样做；

for (var i=0; i<response.d.length; i++) {
 alert(response.d[i]);
}
