使用javascript从页面加载中获取标签文本

Question

我正在使用此功能

<script type="text/javascript" language="javascript">
    function readwebconfig() {
        var sessiontime = "<%= Session.Timeout %>";
        alert(sessiontime);
    }
</script>

现在，我想将此sessiontime值分配给标签文本，我该怎么做。

<asp:Label ID="lblmsg" runat="server"></asp:Label>
