那这个也不难实现，我给你写了一个页面，当然在JavaScript里面我写了一个固定的值，目的只是为了测试，代码如下：
HTML代码：
<%@ Page Language="C#" AutoEventWireup="true"
CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.
<html xmlns="http://www.
<head runat="server">
<title>无标题页</title>
<script type="text/javascript">
function TestValue()
{
var str = "这是测试的输入值";
UseCallback(str);
}
function GetValye(value)
{
document.getElementById("TextBox1").value = value;
}
</script>
</head>
<body onload="TestValue();">
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</div>
</form>
</body>
</html>
后台C#代码：
using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
public partial class _Default : System.Web.UI.Page, System.Web.UI.ICallbackEventHandler
{
string callback = "";
protected void Page_Load(object sender, EventArgs e)
{
string strRefeence = Page.ClientScript.GetCallbackEventReference(this, "arg", "GetValye", "content");
string strScript = "function UseCallback(arg, content){" + strRefeence + ";}";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "UseCallback", strScript, true);
}
public void RaiseCallbackEvent(string eventArg)
{
if (eventArg.Equals("这是测试的输入值"))
{
callback = "传值正确";
}
else
{
callback = "传值错误";
}
}
public string GetCallbackResult()
{
return callback;
}
}
