Pass value into a textbox (on another page) using a hyperlink

Question

Relatively new to JavaScript. Here is what I am trying to do:

1.) User clicks on hyperlink

2.) User is redirected to www.blah.com (a site I don't own)

3.) A value that is stored in the URL populates a textbox box.

BONUS:

4.) After the value is entered in the textbox, a named button is automatically activated to search for the entered string

I know if the textbox is in the SAME webpage as the hyperlink I can do something like:

 <a href="#" onclick="document.getElementById('THEID').value='blah';">THELINK</a>

How do I do this to another page?

Answer 1

You cannot do that for a site you don't own, security issues. You can use GreaseMonkey scripts on chrome if this is more of a hack
