How to force link from iframe to be opened in the parent window?

I found the good solution was to use the base tag. Add the following to the head of the page in the iframe:

<base target="_parent">

This will load all links (anchor links) on the page in the parent window. If you want your links to load in a new window, use:

<base target="_blank">

This tag is fully supported in all browsers.

If you want to a particular link to open parent window use following

<a target="_parent" href="https://www.niceonecode.com">link</a>

With javascript, I found this:

window.parent.location.href= "https://www.google.com";
