从C＃代码重新加载ASP.NET站点中的iframe

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

尝试在C＃修改其属性后重新加载iframe。这是页面：

<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:

当点击按钮时，它会运行：

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?

但是重新加载iframe的行不起作用。有任何想法吗？

How about setting the src for the iFrame via inline code?

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>
