I want to give a warning to user when she tries to navigate away from the page. So I am using a 'Confirm' dialogue. Pressing cancel should stop her from leaving the page.
This is my function which is called from the onUnload of the body tag of the page.
When I click on 'Cancel' button (part of the form within the same page), then this code is called and if I press cancel in the dialogue, user stays on same page.
However, I press any outside link, which takes user to some other page, then pressing cancel in the dialogue doesn't stop user moving away from the page.
