部分渲染后 JavaScript 不执行

我有一个最初隐藏的 asp.net 面板，单击按钮时显示。该面板内有 javascript，在面板设置为可见后它不会执行。我可以看到 javascript 函数在页面上输出，但没有被调用。我该怎么做才能调用该函数？这是一个例子：

<asp:LinkButton id="lbtn" runat="server" Text="show" OnClick="lbtn_Click" />
    <asp:UpdatePanel id="upnl" runat="server" UpdateMode="Conditional">
       <contenttemplate>
        <asp:panel id="pnlContent" runat="server" visible="false">
            content initially hidden.

            <script>
                alert('done!');
            </script>
        </asp:panel>
    </contenttemplate>
    <triggers>
        <asp:AsyncPostBackTrigger ControlID="lbtn"/>
    </triggers>
</asp:UpdatePanel>

I have a asp.net panel that is initially hidden and is shown when a button is clicked. There is javascript inside that panel and it doesn't execute after the panel is set to be visible. I can see that javascript function gets outputted on page but it is not called. What can I do to make it so that function gets called? Here is an example:

<asp:LinkButton id="lbtn" runat="server" Text="show" OnClick="lbtn_Click" />
    <asp:UpdatePanel id="upnl" runat="server" UpdateMode="Conditional">
       <contenttemplate>
        <asp:panel id="pnlContent" runat="server" visible="false">
            content initially hidden.

            <script>
                alert('done!');
            </script>
        </asp:panel>
    </contenttemplate>
    <triggers>
        <asp:AsyncPostBackTrigger ControlID="lbtn"/>
    </triggers>
</asp:UpdatePanel>

您可能希望有某种结束请求方法，每当调用 ajax 方法时都会调用该方法。这必须位于脚本资源下。

<script type="text/javascript">

    var prm = Sys.WebForms.PageRequestManager.getInstance();
    prm.add_endRequest(function(sender, args){ alert("endRequest"); });

</script>

You'll probably want to have some sort of end request method that gets called whenever an ajax method is called. this would have to be under the script resource.

<script type="text/javascript">

    var prm = Sys.WebForms.PageRequestManager.getInstance();
    prm.add_endRequest(function(sender, args){ alert("endRequest"); });

</script>
