在C#修改其属性后尝试重新加载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>
单击按钮时,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" });
但重新加载iframe的行不起作用。有什么想法吗?

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>
