This is really not a UI question, but since I didn't see the original

That's not quite it. The problem is that by declaring somevar with
"var" you gave it the scope of the current function, which has
completed by the time you click the delete button in dialog. So at
that point somevar does not exist.

Yes, you need some place to store somevar. One option might be to
keep in the the global scope, which should work if you just removed
"var" from the declaration. But there are many reasons why this is
not considered great practice. The other obvious place to store it is
in the dialog itself, with a line something like:
$("#dialog").data("somevar", $(this).attr("id"));
Then the delete function could use something like:
window.location = "/home/" + $(this).data("somevar") ;
This is entirely untested, but I think it should get the idea across.
Good luck,
