Get input values from seperate url???

Is it possible in simple html/js to populate input values in Page2 with input values from Page1 without writing a script for each input?

Page1: FRAMES.htm –
<input type=”hidden” height=”0″ name=”order_no” value=”{ORDER_NO}”>
(Value passed dynamically from PHP.CRM)

USING SOMETHING LIKE….
Page2 MAIN_FRAME.htm
<input readonly type=”text” name=”order_no” size=”20″ value=”value.document_page1.order_no”>

Or rerhaps using CSS to class the inputs in page 2??

I know, I know… Why not just have the CRM pass the value directly to page2 in the first place right? LONG STORY, DON’T ASK. Can it be done and in what syntax?

Anyone???

Also in #HTML _↴
