Menu
I am using this code to warn a user if they have changed data on a form. It works using IE or netscape 7.2 on windows but not using IE 5.2 or safari on a Mac.
var form_submitted = false;
var form_changed = false;
window.beforeunload = exitCheck();
function exitCheck(evt){
if (form_submitted == false && form_changed == true)return “Any string value here forces a dialog box to nappear before closing the window.”
}
<BODY onBeforeUnload=”return exitCheck();”>
Any ideas?
