How to use viewstate value in Javascript in asp.net??

推荐答案

使用RegisterHiddenField而不是混合服务器/js代码:

JavaScript:

Use RegisterHiddenField than mixing server/js codes:

JavaScript:

<script language="javascript" type="text/javascript">
    var vCode = document.getElementById("vCode");
alert(vCode);
</script>

背后的代码:

Code behind:

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
