Tutorial :IE prompt about unsaved form data


I'm having an unexpected "annoying" popup in IE7 (and possibly other versions). As expected IE prompts you about unsaved form data when closing the window which is fine. But I have a form inside a div and now when I toggle the display CSS style between none and block, IE thinks I'm closing the form with unsaved data and shows the warning about closing an unsaved form! I don't want my users to be annoyed when simply hiding a form in my IE-based web app.

Anyone know how to overcome this?


Make sure that your doc type is transitional rather than strict


The prompt isn't IE's-- your HTML has an onbeforeunload handler which triggers the warning.
