Through the Square (javascript) Window
For the Cohere site, I’ve been trying to figure out how you can keep track of a pop up window using Javascript even when the parent page changes (to another page on same domain) and to know whether the pop up window is already open. I’m having exactly the problem mentioned in this forum post – but as yet no solution.
All the example scripts I’ve found so far will only work if the parent page remains the same. I.e. you’re testing whether the pop up is already open, but applying this test on the document/page that originally opened the popup. What I’m looking to do is subtly different – so the pop up remains open so as you are browsing Cohere you can add ideas to make connections between.
I would think that this ought to be possible, because if you open a popup window with the same name as an existing one, the old one will get overwritten – so it ‘knows’ that the pop up exists. Plus, this is all running from the same domain, so there won’t be any cross domain issues.
If anyone has any pointers as to how to achieve this, it would be much appreciated. Or if you have other suggestions for how the same results could be achieved. Cheers 
Any success tackling this issue already? I was just wondering if this was possible and looking for a solution. nothing found so far.
