showmodaldialog and location.href
I am trying to use a showmodaldialog() popup window. This window has a dropdown which the user will select a set. The particular set which is chosen is supposed to affect what appears in another dropdown right below it.
BTW, this is using PHP, too, to access data from a database. So, what the user chooses in the first dropdown should trigger a query done by PHP, which should output the options into the second dropdown.
Help would be highly appreciated.
