How do I pass any array to a window being opened with window.open()

Question

I have any array called query[]

I am opening a new window with:

  window.open(\"http://localhost:8081/myapp/Query.action\",\"mywindow\",\"me         


        

Answer 1

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 comma separated list that can be read in the target page.

Answer 2

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.
