I have any array called query[]

I am opening a new window with:

  window.open("http://localhost:8081/myapp/Query.action","mywindow","menubar=1,resizable=1,width=600,height=400");

How do I pass this array to the new window so I can use it there.

EDIT: I just found this, Pass array to Window which will probably provide the answer.

EDIT2: the answer provided in question 2487420 doesn't seem to work, I am using FireFox and openDialog never opens a new window

New Requirement: This only has to work on FireFox because I am only using it for testing.

• what does the array contain? If it's simple items (e.g. numbers) see my answer. – user447356 Commented May 1, 2011 at 12:41

You can't "pass" the array, but you can make it available as a global (or via a global), and your new page can use something like:

 var theArray = window.opener.theArray;

to get access to it.

Alternatively, you could pass the array through as a list of parameters, but if it's not otherwise interesting to the server then that would be a little wasteful.

You can also pass it on the URL as well, for example:

window.open("http://localhost:8081/myapp/Query.action?arr=" + query.join(","), "mywindow", ...

This will pass it as ma separated list that can be read in the target page.
