使用 Javascript 和 ASP 从 AJAX 获取价值
我正在使用这个 Ajax 代码.但我不知道如何使用 Javascript 在服务器端 asp 上检索 value1 的值.
I am using this Ajax code. But I dont know how i will retrieve my value of value1 on my server-side asp using Javascript.
在我的服务器端，我想要类似的东西<%var newdata = value1 (这是来自服务器端的 - 在此处发送)%>
On my serverside I want to have something like <% var newdata = value1 ( which is the one from the serverside - which was send here) %>
请帮忙！！！谢谢一百万

推荐答案
当您的 Ajax-Request 成功时，您将在 Request-Object 的 QueryString-Collection 中拥有 querystring-variables.
When your Ajax-Request succeeds you will have the querystring-variables in the QueryString-Collection of the Request-Object.
在服务器端可以这样工作:
Could work like this on the server side:
<% var newdata = Request.QueryString("value1"); %>
