如何使用JQuery每1秒发送一次Ajax请求？

How to send Ajax request on every 1s using JQuery ?

推荐答案

您可能不希望每次都发送请求第二，正如大卫已经指出的那样。

You probably don't want to send a request every second as David already noted.

因此，使用 setInterval 是一个坏主意。

Therefore, using setInterval is a bad idea.

相反，请考虑做以下事情：

Instead consider doing something like this:

function doAjax() {

  $.ajax({
   ...
   complete: function() {
    setTimeout(doAjax,1000); //now that the request is complete, do it again in 1 second
   }
   ...
  });
}

doAjax(); // initial call will start rigth away, every subsequent call will happen 1 second after we get a response
