clearTimeout和setTimeout [英] clearTimeout and setTimeout

问题描述

大家好，

我遇到一种情况，用户输入搜索查询，并且在输入框的每个键入事件上，我都设置了一个超时(setTimeout)来执行搜索(asp.net脚本服务调用).但是，如果用户仍在输入搜索查询，则必须清除设置的超时时间.
我尝试了一些看似合理的方法，但是没有，没有很多乐趣！

代码:

Hi guys,

I have a situation where a user enters a search query and on each keyup event of the input box i set a timeout (setTimeout) to execute the search(asp.net script service call). But if the user is still typing a search query i have to clear the set time out.
I have tried something that looks reasonable but no no, not much joy!

Code:

var x = '';
$('#search').keyup(function ()
{
    clearTimeout(x);
    x = setTimeout("GetSearchResults($('#search'));", 100);
});

我尝试将超时时间延长为300、400、500，但是执行查询需要很长时间，这是不可取的

关于如何解决此问题或我可以使用的任何其他方法的任何建议?
感谢您的帮助.

祝您编程愉快，

I tried increasing the timeout period to say 300, 400, 500 but then the query takes long to execute which is not preferable

Any advise of how i can resolve this or any other approach that i could use?
Will appreciate any help guys.

Happy coding,
Morgs

推荐答案

(' #search').keyup(函数() { clearTimeout(x); x = setTimeout("

('#search').keyup(function () { clearTimeout(x); x = setTimeout("GetSearchResults(

('#search'))); "，

('#search'));", 100); });

看到您已经在使用JQuery，为什么不使用autocmplete插件；
http://docs.jquery.com/Plugins/autocomplete [

Seeing as you are already using JQuery, why not use the autocmplete plugin;
