通过这个code我可以显示动画GIF服务器脚本运行时：

With this code I can show an animated gif while the server script is running:

function calculateTotals() {
    $('#results').load('getResults.php', null, showStatusFinished);
    showLoadStatus();
}

function showLoadStatus() {
    $('#status').html('');
}


function showStatusFinished() {
    $('#status').html('Finished.');
}

不过，我想展示的远沿着剧本怎么样，比如状态加工生产线20000 342 ......，并有指望它，直到它完成。

However, I would like to display a status of how far along the script is, e.g. "Processing line 342 of 20000..." and have it count up until it is finished.

我怎么能这样做？我可以做一个服务器脚本包含不断更新的信息，但我在哪里把命令读取这个，比方说，每一秒？

How can I do that? I can make a server-script which constantly contains the updated information but where do I put the command to read this, say, every second?

推荐答案

阅读您的意见对安德鲁的回答后。

After reading your comments to Andrew's answer.

您会读的状态是这样的：

You would read the status like this:

function getStatus() {
    $.getJSON("/status.php",{"session":0, "requestID":12345}, 
    function(data) { //data is the returned JSON object from the server {name:"value"}
          setStatus(data.status);
          window.setTimeout("getStatus()",intervalInMS)
    });
}

使用这个方法，你可以在服务器上打开几个同时XHR请求。

Using this method you can open several simultaneous XHR request on the server.

所有status.php以输出为：

all your status.php as to output is :

{"status":"We are done row 1040/45983459"}

不过，您可以输出尽可能多的信息，你想在响应和相应的处理（进料例如一个进度条或执行的动画..）

You can however output as many information you want in the response and to process it accordingly (feeding a progress bar for example or performing an animation..)
