这是在回调的窗口。使用给予回调的每个值：

  $（。时间）。每个（函数（指数，ELEM）{
            VAR sendTime = $（本）.attr（数据时间）;
            dataString =sendtime =+ sendTime +与＆amp; Q = convertTime;
            $阿贾克斯（{
                键入：POST，
                网址：data_handler.php
                数据：dataString，
                缓存：真正的，
                成功：函数（响应）{
                    警报（响应）;
                    $（ELEM）。html的（响应）;
                }
            }）;
        }）;
 

您的不的需要定义一个新的变量，以保护这在jQuery已经会为你。

j query

setInterval(function() { 
            $( ".time" ).each(function( index ) {
                var sendTime=  $(this).attr("data-time");
                dataString = "sendtime="+sendTime+"&q=convertTime";
                $.ajax({
                    type: "POST",
                    url: "data_handler.php",
                    data: dataString,                   
                    cache: true,
                    success: function(response) {
                        alert(response);
                        $(this).html(response);
                        //alert(response);
                    }
                });
            });
        }, 5000);

this is the window in the callback. Use the value given to the callback of each :

        $( ".time" ).each(function(index , elem) {
            var sendTime=  $(this).attr("data-time");
            dataString = "sendtime="+sendTime+"&q=convertTime";
            $.ajax({
                type: "POST",
                url: "data_handler.php",
                data: dataString,                   
                cache: true,
                success: function(response) {
                    alert(response);
                    $(elem).html(response);
                }
            });
        });

You don't need to define a new variable to protect this as jQuery already does it for you.
