How to change the url of a parent window from a pdf in a pop up.

Acrobat uses Acrobat JavaScript not HTML JavaScript. There are many differences. See the Acrobat JavaScript reference, the link is in the anchored FAQ's for this forum.

I've been going through the Acrobat Javascript api docs and can't find anything that seems to do what I require. Can anyone point me in the right direction?

Have you read the description of the "launchURL()" method under the "app" objcect?

Have you found a "window" object or "location" property?

app.launchURL() appears to only allow opening of a url in the same or a new browser window.

What I'm after is to be able to modify the url of the parent browser window which created the window with the pdf in it.

For security reasons there is very little control a PDF JavaScript can exert over the browser environment. But there are some tricks you can play. They may not always work because of external factors like the user's version of Acrobat/Reader and thier browser security settings. But try this script from a button in a PDF

app.launchURL("javascript:window.navigate('http://www.windjack.com')");

Within limitations you can pass Browser JavaScript commands in an URL from Acrobat JavaScript.
