Apologies for my ignorance, I'm new to JavaScript and web development in general.

I have a page (A) that links to another page (B).

Inside page (B) I have a bit of code with some variables defined in JS like this:

<html>
  <body>

    <script type="text/javascript">

      var big_string = "I am a large string";

    </script>

  </body>
</html>

I'm trying to write a greasemonkey script that will get the value of big_string and append it to a var in page (A). I feel like I ought to be able to get big_string from inside (A) since I have a link to (B) but I can't find any examples of how to do this. Is what I'm trying to do possible or am I going about this in the completely wrong way?

check this out `http://browserify.org/` it'll help you to include the js of page 2 to page 1 – ashishmohite Dec 13 '15 at 02:31
@NEO-xx, try reading the question again. Browserify won't help in this instance. – Andy Dec 13 '15 at 02:47
What do you mean by "linked to"? You mean via an `` tag, or is it a popup, or are you referring to different tabs on a browser? – jwatts1980 Dec 13 '15 at 02:47
Linked as in I have the href from the tag on page (A) that points to page (B). – anophthalmia Dec 13 '15 at 02:57
Your case is *probably* simpler than the duplicate, but you did not provide enough details for us to be sure. The linked approach will work in almost every case. For your situation you would either message-back `unsafeWindow.big_string` or parse the appropriate ` – Brock Adams Dec 13 '15 at 04:04
