jquery - JSON 格式问题

Question

现在我正在收到 JSON url 响应，因为我想漂亮地打印此 URL

[{"chat":"ed test","displayname":"Ed Student","created_at":"2014-03-29 21:42:35"},
{"chat":"test from sue","displayname":"Sue Student","created_at":"2014-03-29 21:42:25"},{"chat":"Test from instructor","displayname":"Jane Instructor","created_at":"2014-03-29 21:42:18"}]

但我想让它看起来像这样:

[

   {

     "chat":"ed test",
     "displayname":"Ed Student",
      "created_at":"2014-03-29 21:42:35"},
    {
      "chat":"test from sue",
      "displayname":"Sue Student",
    }
]

等等。

我的代码如下:

$.ajax({

        type: "POST",
        url: "chatlist.php?PHPSESSID=9c2b21f6309fd0cb8c157b54eafb7381",
        cache: true,
        async: true,
        dataType:"json",
        data: JSON.stringify(messages, null, 4),
    success: function(data){ 
            $("#messages").empty();
            for (var i = 0; i < data.length; i++) {
                entry = data[i];
                $("#messages").append("<p>"+htmlentities(entry.chat)+'<br/>&nbsp;&nbsp;'
                        +htmlentities(entry.displayname)+' '+htmlentities(entry.created_at)+"</p>\n");
                    console.log(JSON.stringify(data[i]));
            }
            OLD_TIMEOUT = setTimeout('messages()', 4000);
        }
  });

是否可以格式化我通过此 $.ajax 调用获得的响应 URL？

我认为您正在寻找，

JSON.stringify(value[, replacer [, space]])

喜欢，

var data = JSON.stringify(data, null, "\t"); // Using a tab character mimics standard pretty-print appearance

console.log(data);
