如何限制jQuery事件的回调? [英] How to throttle callback of jQuery event?

问题描述

好吧，所以我确实像在google中一样进行搜索，您在输入中输入文字，它会立即为您提供输入.但是我不喜欢那样.我使用类似的$("TEXTINPUT").keyup(function() {.当用户键入速度非常快时，它会多次连接到数据库.是否有可能仅在用户停止键入1-2秒而不是立即停止输入时才连接到PHP文件?我需要在jQuery中执行此操作.谢谢.

Ok, so I do search like in google, you type text in input and it gives you entries instantly. But I don't like that. I use something like that $("TEXTINPUT").keyup(function() {. When the user types very fast, it connects to database many times. Is it possible, that we would connect to PHP file only when user stops typing for 1-2 seconds, but not instantly? I need to do that in jQuery. Thanks.

推荐答案

尝试:

var time_out;
$("TEXTINPUT").keyup(function(){
    clearTimeout(time_out);
    time_out = setTimeout(your_function, 500);
}

function your_function()
{
    /*CHECK DATABASE*/
}
