KEYUP（函数（））AJAX请求延迟 - jQuery的

问题描述：

我有一个jQuery Ajax请求，我想用文字输入打电话，所以我嵌套它里面的 KEYUP（函数（）。这工作得很好。

I have a jQuery Ajax request, that I want to call with text input, and so I nested it inside keyup(function(). This works fine.

$("#text_box").keyup(function() {
 //AJAX REQUEST
});

但有时这种行为越野车。当我输入一些文字非常快，我得到的结果与原来的输入字省略了一些最后一个字母输入字（可能有些挑剔的浏览器）。我想在没有进行第二次输入活动Ajax请求被发送，我的意思是，如果我输入文字非常快，休息一秒钟（意味着我所做的输入）。我怎样才能做到这一点？

But this behaves buggy sometimes. When I input some text very fast, I am getting results for input word with some last letters of the original input word omitted (may be some fault with browser). I want the ajax request to be sent when there is no input activity for a second, I mean, if I input text very fast and rest for a second (means I made the input). How can I do this?

答

听起来好像你从一个previous Ajax调用的结果。使用定时器的setTimeout 和 clearTimeout 。

It sounds as if you get results from a previous ajax call. Use a timer with setTimeout and clearTimeout.

var timer = null;

$("#text_box").keyup(function() {
  if(timer) {
    clearTimeout(timer);
  }

  timer = setTimeout(someFunction, someDelay);
});

其中， someFunction 是一个函数，它确实你的Ajax调用和 someDelay 是想要做之前要等待的延迟通话时，用户之后输入，以毫秒为单位。

Where someFunction is a function which does your ajax call and someDelay is the delay you want to wait before doing the call, after the user has typed, in ms.
