Onunload return false event help

[iainwood]

Hi

 

I have a backoffice system for my users, there is quite a complicated form in this that I need to make sure is saved on unload.

 

My initial idea was to have a variable set by javascript on onchange and onkeydown functions on the elements - this works  fine I can detect if they have potentially changed anything

 

OnUnload I check this variable and ask them to confirm that they want to leave the changes, however if they click cancel the page still exits!

 

so i tried making it offer to submit the form (see below)

 

function confirmExit(){

alert(changeDetected) // just to show me the variable

if (changeDetected!=0){

if(confirm("Do You Want to Save Changes")){

document.form1.submit()

}

}

 

does anyone have a method for this? It must work in IE, ideally be cross browser!

 

Thanks Iain
