@winsonleeauthorOct 19.2005 — #A default msg is being used for the on exist alert. I would like to know if i am able to customise msg so that i can type my own msg for the on exit ??

[code=html]
 
 <script type="text/javascript"><!--
 var actuallysubmitted=false;
 function unloadCheck() {
 //onunload doesn't work for this; you have to use onbeforeunload
 // IE4+/Win, Mozilla 1.7a+, Netscape 7.2+, and Firefox support onbeforeunload.
 if(!actuallysubmitted){
 var f =document.myform;
 flds = f.elements;
 for(var i=0;i<flds.length;i++) {
 if(flds[i].value != flds[i].defaultValue) {
 return false;
 }
 }
 }
 }
 // -->
 </script>
 
 [/code]

@KravvitzOct 19.2005 — #Change
return false;
to
return 'your custom message';

@winsonleeauthorOct 20.2005 — #it is so weird. when i click on the link which it suppose to call the test function, but ended up the unloadCheck is called before calling the test function. i wonder why this happends ?

@KravvitzOct 20.2005 — #It's because the onbeforeunload is triggered before the href is processed because normally the href is a URL to be followed, thus often will cause the page to unload.

You may want to use onclick instead of href="javascript:...".
