将值从Javascript传递给aspx [英] Passing values from Javascript to aspx

问题描述

我的程序需要将Javascript中的变量值传递给ASPX.有人可以告诉我该怎么做吗?

My program needs to pass a variable value from Javascript to ASPX. Can somebody tell me how to do this?

function controlvalue(){
    var myTextField = document.getElementById('FileUpload1');

 alert("You entered: " + myTextField.value)
}

这里myTextField.value需要传递给aspx

here myTextField.value needs to be pass to aspx

推荐答案

<script type="text/javascript">

function test()
{
  var str="value";
  document.getElementById("hidden1").value=str;
}
</script>

<input id="hidden1" type="hidden" runat="server" />
        <asp:Button ID="Button1" runat="server" OnClientClick="test()"

 Text="Button"

onclick="Button1_Click" />

protected void Button1_Click(object sender, EventArgs e)
{
    Response.Write(Hidden1.Value);
}

1.我认为您可以轻松地同时使用这两个函数，我的意思是，如果我在客户端使用javascript在txtbox1上写一些文本，则可以从服务器端使用.text检索该文本(前提是该控件禁用了viewstate ).

谁能批准我的理解.我也可能是错的.

1. I think you can use these two in unison easily, i mean If i write some text on a txtbox1 using javascript on client side I can retrieve that using .text from server side (provided the viewstate is disabled for that control).

Could anyone ratify my understanding. i might be wrong too.

U可以使用jquery-ajax来调用页面方法..
