如何在ASP.NET网页上获取参数 [英] How to get Parameter on a ASP.NET WebPage

问题描述

我使用AJAX作为JavaScript使用javascript发送了参数"q"

I sent the parameter ''q'' using javascript using the AJAX as

var sendingStr = "Default.aspx?q=" + document.getElementById('q').value;
xmlHttpRequest.open("GET", sendingStr, true);

================================================== =========================



现在，在Default.aspx页面上使用C#，我想获取"q"参数的值.

我搜索了网络.有点像...

qStr = Request.QueryString ["q"].ToString();

我调试了.它显示qStr为空

它没有用.错误在哪里?

如何获取该参数?
