iframe无法为相同的网址加载 [英] Iframe not loading for same url

问题描述

在按钮上单击页面，将src属性赋予IFRAME，页面加载正常.

例如http://myserver/result.aspx?id = 1

对于第二个单击按钮，当传递了不同的URL时，页面加载正常
例如http://myserver/result.aspx?id = 2


对于第二个按钮，当传递相同的URL时，请单击，以防第2页未在iframe中加载.
例如http://myserver/result.aspx?id = 2

如何防止这种行为.即使src网址相同，我也想加载iframe.

谢谢

Vijay

Hi,

On a button click on a page, I give src attribute to the IFRAME and page loads fine.

e.g. http://myserver/result.aspx?id=1

For a second button click when different url is passed page loads fine
e.g. http://myserver/result.aspx?id=2


For a second button click when same url is passed as in case 2 page doesnt load in iframe.
e.g. http://myserver/result.aspx?id=2

How to prevent this behaviour. I want to load iframe even if the src url is same.

Thanks

Vijay

推荐答案

我认为您在！IsPostBack中遇到问题.
当您单击第二个按钮时，将再次调用Page_Load方法.
因此，请执行以下操作->

受保护的void Page_Load(对象发送者，EventArgs e)
{
如果(！IsPostBack)
{
//您的默认网址集.
}
}

I think you have a problem in !IsPostBack.
When you click the 2nd button then Page_Load method is again called.
so, do something like this ->

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
// your default url set.
}
}

你好，

如何在网址后附加一个随机数?在这种情况下，URL将始终是不同的.

hello,

How about appending a random number to the url? In that case the URL will always be different.

Random r = new Random(10000);
        myIframe.Attributes.Add("src", "http://myserver/result.aspx?id=1&r=" + r.Next().ToString());
