从iframe打开页面到新窗口/标签页

Question

I have a page with an iFrame on it. On the page in the frame I have a button.

What I want is that if the user clicks on the button, another page is opened in it's own new window or tab. This functionality is to show the user a print friendly page.

How can I do this?

This is how I now try it:

Dim sb2 As New StringBuilder
sb2.Append("window.open('")
sb2.Append(sb.ToString)
sb2.Append("','NewPFWindow','menubar=1,toolbar=1,scrollbars=1,resizable=1,sandbox=""allow-same-origin allow-forms""')")

ClientScript.RegisterClientScriptBlock(Me.GetType, "si2", sb2.ToString, True)

sb holds the page like "mypage.aspx"

Another option is to resize the iFrame so the whole page will fit. Is that possible from code-behind?

Answer 1

Just provide a target that has not been named on your site yet, most people will use _blank for that

Ie

<a href="desiredLocationUrl...." target="_blank"> link text </a>

or if you want to tie that to another click-event somewhere else:

window.open('desiredLocationUrl....', "_blank"); 

Btw. it does not matter if that link is inside an iframe ;)

Answer 2

found it.

Apparently Chrome uses an undocumented feature.

The frame that is trying to put the new page in it's own window or tab, needs an extra option in the sandbox property called "Allow-popup'.

This is not documented on the w3schools.com website.

So by adding this to the sandbox property, you allow the browser to create new window/tab.
