Anybody suggest me how to do it?

推荐答案

我会建议使用RegisterHiddenField比混合服务器/ JS codeS：

I would suggests to use RegisterHiddenField than mixing server/js codes:

您可以尝试此示例：

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    ViewState("code") = "EE"
    Page.ClientScript.RegisterHiddenField("vCode", ViewState("code"))
End Sub

在你的JavaScript：

On your javascript:

var vCode = document.getElementById("vCode");
alert(vCode);
