后台代码中如何创建iframe啊
我现在想实现这样的功能:通过一个数组,如private string[] WebSiteList ={ "www.163.com ", "www.126.com "};,这里面包含2个网址,然后点击一个button,把这2个网站用2个iframe显示,怎么做啊.
[解决办法]
不用后台做吧
前台可以使用javascript做的
方法为
var iframe1=document.createElement( "iframe ");

[解决办法]
服务器端：
protected System.Web.UI.WebControls.Button Button1;
public System.Text.StringBuilder sb;
private void Page_Load(object sender, System.EventArgs e)
{
sb = new StringBuilder();
}
private void Button1_Click(object sender, System.EventArgs e)
{
string[] WebSiteList ={ "www.163.com ", "www.126.com "};
for(int i=0;i <WebSiteList.Length;i++)
{
sb.Append( " <iframe src= 'http:// " + WebSiteList[i] + " '> </ifreame> ");
}
}
客户端:
<body MS_POSITIONING= "GridLayout ">
<form id= "Form1 " method= "post " runat= "server ">
<asp:Button id= "Button1 " style= "Z-INDEX: 101; LEFT: 168px; POSITION: absolute; TOP: 48px " runat= "server " Text= "Button "> </asp:Button>
<%=sb.ToString()%>
</form>
</body>
是不是这样呀
