我已经陷入这个问题好几天了。
1-用户按其中一个按钮
2-按下按钮在 LABEL-＆gt; lbJavaScriptVar 内插入.js变量
3- Sys.Application.add_load（GridJson）; 调用.js函数
问题是，我无法改变变量＆＃34; SHOWTHIS＆＃34; UpdatePanel中的值值永远不会改变
----------------------------- [ASPX] --------------- ---------------------
<head>
<script type="text/javascript">
function GridJson()
{
alert(SHOWTHIS);
document.getElementById("Grid").innerHTML =
"<tr><td>" + SHOWTHIS+ "</td></tr>"
}
</script>
</head>
...
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:Button ID="btMan" runat="server" OnClick="btMan_click" Text="Man"/>
<asp:Button ID="btWoman" runat="server" OnClick="btWoman_click" Text="Woman"/>
<asp:Label ID="lbJavaScriptVar" runat="server" ></asp:Label>
<table id="Grid" border="5" class="cssMiniGrid"></table>
<script type="text/javascript">Sys.Application.add_load(GridJson);</script>
</ContentTemplate>
</asp:UpdatePanel>
----------------------------- [/ ASPX] -------------- ----------------------
----------------------------- [CS] -------------- ----------------------
(btMan_click)...
lbJavaScriptVar.Text = "<script> var SHOWTHIS= 9999</script> ";
(btWoman_click)...
lbJavaScriptVar.Text = "<script> var SHOWTHIS = 7777</script> ";

已编辑 ...感谢你的sugestions，编辑这些行以使其正常工作
.ASPX<
[ALTER]function GridJson() ------> function GridJson(SHOWTHIS) {
.CS
[DELETE](btMan_click)...
[DELETE]lbJavaScriptVar.Text = "<script> var SHOWTHIS= 9999</script> ";
[DELETE](btWoman_click)...
[DELETE]lbJavaScriptVar.Text = "<script> var SHOWTHIS = 7777</script> ";
[INCLUDE]ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "", "GridJson(" + "THANKS" + ");", true);
注意：我首先在Web用户控件中创建了此代码，现在代码位于根页面

以这种方式尝试
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "", "myFunction('value');", true);
然后在javascript中
function myFunction(parameter){
SHOWTHIS= parameter;
}

使用ScriptManager.RegisterStartupScript附加脚本
