从嵌套iFrame重定向父iFrame

Question

I saw this question on redirection iFrames Redirect parent window from an iframe action but the answer addressed redirecting the entire page.

The redirect was using:

window.top.location.href = "http://www.example.com"; 

Is there a way to redirect nested iFrames?

ie.

<browser>
    <iframe src="someSrc">
        <!--iFrame page-->
        <iframe src="nestedSrc"></iframe>
    </iframe>
</browser>

So from the nestedSrc redirect someSrc to another page instead of redirecting the browser page.

Answer 1

If you have access to the parent iframe's domain, you can simply redirect it using:

window.parent.location = 'http://new.location.com';

Small parent / top example

<Browser>
    <iframe1>
        <iframe2>
        </iframe2>
    </iframe1>
</Browser>

Inside iframe2 the following are true:

window.parent.parent == window.top // true
window.parent == window.top.frames[0] // true

Note: the following example presumes browser and iframe 1 & 2 all are from the same domain
