例如，如果我加载上面的 json 数据，我会得到如下图所示的无序时间戳。我从 ehcache 获取这些数据（无序），我想在客户端按时间戳对其进行排序。

这是 jsfiddle link，如果您在结果中看到时间戳不是按升序排列的。

代码：

 $(document).ready(function () {
   var json = //json object above
   for (var i = 0; i < json.length; i++) {
        tr = $('<tr/>');
        tr.append("<td>" + (i+1) + "</td>");
        tr.append("<td>" + json[i].userName + "</td>");
        tr.append("<td>" + json[i].conversation + "</td>");
        tr.append("<td>" + json[i].timestamp + "</td>");
        $('table').append(tr);
     } 
    });

【问题讨论】：

你的问题太模糊了。向我们展示您如何使用它来了解应用排序功能的最佳方式。无论如何，如果它是由数据库查询生成的，一个好的做法是在服务器端应用这种排序。
@DontVoteMeDown 我已经用快照更新了我的问题，数据来自 ehcache，我们想在客户端对其进行排序。
很好，但这还不足以提供帮助。我们想知道您如何在代码中使用json。您从服务器接收它，然后简单地循环遍历它？
@DontVoteMeDown 我在浏览器打开时获取一次数据，如果它只是纯数字，我可以循环遍历时间戳。
抱歉，没明白你的意思。

【解决方案1】：

您的日期格式可以按字母顺序排序，因此您可以简单地使用sort 并直接比较字符串而无需转换为日期。

json.sort(function (a, b) {
    if (a.timestamp > b.timestamp){
      return 1;
    } else if (a.timestamp < b.timestamp){
      return -1;
    } else {
        return 0;
    }
});
