从C＃代码在ASP.NET网站中重新加载iframe

Question

Trying to reload an iframe after C# has modified its attributes. Here's the page:

<script type="text/javascript">
    function reloadFrame(Map) {
        document.getElementById(Map).contentDocument.location.reload(true);
    }
</script>

<asp:TextBox ID="TextBox1" placeholder="Zip code" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Find locations" onclick="Button1_Click" />
<iframe id="Map" runat="server"></iframe>

And when the button is clicked it runs this:

var zipCode = TextBox1.Text;
Map.Attributes.Add("src", "https://www.google.com/maps/preview#!q=gnc+near%3A+" + zipCode);        
browser.Document.InvokeScript("reloadFrame", new[] { "Map" });

However the line to reload the iframe doesn't work. Any ideas?

如何通过内联代码为iFrame设置src？

<iframe id="Map" runat="server" src='<%= (TextBox1.Text == "" ? "" : "https://www.google.com/maps/preview#!q=gnc+near%3A+" + zipCode) %>'></iframe>
