如何在asp.net中动态更改iframe的src [英] how to change src of an iframe dynamically in asp.net

问题描述

我有一个动态更改iframe的src的问题，任何帮助都可以理解..........谢谢你...

hi , i am having a problem of changing the src of a iframe dynamically any help could be appreciated ..........thank u...

推荐答案

试试这个：

为你的iframe添加 runat =server属性。

try this:
Add runat="server" attribute to your iframe.

<iframe id="urIframe" runat="server"></iframe>

将 runat =server attrubute添加到您的iframe后，您就可以从代码隐藏中访问您的iframe。



现在从codebehind添加 src 属性：

Once you add runat="server" attrubute to your iframe you can access your iframe from codebehind.

Now add src attribute from codebehind:

urIframe.Attributes.Add("src","http://www.facebook.com");

祝你好运。

Good luck.

Page:

<form id="Form1" method="post" runat="server">
<iframe id="ifrm" runat="server"></iframe>
</form>
Codebehind:

using System.Web.UI.HtmlControls;
public partial class test : System.Web.UI.Page
{

    protected void Page_Load(object sender, EventArgs e)
    {

       ((HtmlControl)(form1.FindControl("ifrm"))).Attributes["src"] = "http://www.yahoo.com";
    }

HTML：



< iframe id =gameframerunat =serverwidth =1000height =500align =middlesrc =>< / iframe>





This.gameframe.Attributes（src）=game url;

OR

HTML :

<iframe id="gameframe" runat="server" width="1000" height="500" align="middle" src=""></iframe>


This.gameframe.Attributes("src") = "game url";

也试试这段代码

also try this code

HtmlControl MyFrame = (HtmlControl)this.FindControl("urIFrameName");
     MyFrame.Attributes["src"] = "yourPageName.aspx";
