如何加载AJAX（jQuery的）请求响应逐步无需等待它完成？ [英] How to load an ajax (jquery) request response progressively without waiting for it to finish?

问题描述

我想要将使用jQuery的关键字列表提交给一个PHP文件格式，该文件可能需要大量的时间取决于关键字列表的大小来加载。

I want to make a form that will use jquery to submit a list of keyword to a php file, this file could take a lot of time to load depending on the size of the keywords list.

我想要做的是加载PHP响应转换成实时股利或容器不使用内置页框。

What I want to do is to load the php response into a div or container in real time without using iframes.

我所知道的Ajax请求必须等待，直到请求不必响应访问之前完成，我需要访问即使还没有完成，所以我可以实时更新的进步响应。

All the ajax request I know have to wait until the request has finished before having access to the response, I need to get access to that response even when it hasn't finished so I can update the progress in real time.

推荐答案

确实有一种方法。随着老式xmlhttpobjects我监视readyState的。就绪状态4表示请求已经结束。就绪状态3意味着我可以得到一些输出，并等待更多：

Indeed there is a way. With plain old xmlhttpobjects I monitored the readyState. Ready state 4 means the request has ended. Ready state 3 means I can get some of the output and wait for more:

request.onreadystatechange=function()
{
    switch(request.readyState)
    {
        case 4:
            console.log("all good things come to an end");
        break;
        case 3:
            console.log("o, hai!" + request.responseText);
        break;
    }
}

我相信你可以实现使用jQuery相同的：<一href="http://stackoverflow.com/questions/287286/jquery-is-req-readystate-3-possible">http://stackoverflow.com/questions/287286/jquery-is-req-readystate-3-possible
