How do you give a warning message whenever a user leaves a window without saving ??

How do you give a warning message whenever a user leaves a window without saving ??

Here is the answer,  you have to enter the static id in all the different controls that you wish to exclude from the message…

I changed the original script from another blog to use this static id instead of the value.  It works now

Here is the original blog

You have to go into the script and add a line for every control  that you wish to exclude from the warning message. Now you will get an error message every time you leave the form after making changes except for when the excluded controls are pressed.

You can see the highlighted code below to see what I changed from the original script.

Put the following code in the HTML header of the page.

---------

<script type="text/javascript">

$(function(){

$('#wwvFlowForm').data('htmldb',{'dirty':false});

$(':input:not(:hidden,:submit,:password,:button)').live('change',function(){

   $('#wwvFlowForm').data('htmldb',{'dirty':true})

});

$(window).bind('beforeunload',function(){

  if($('#wwvFlowForm').data('htmldb').dirty){return "The changes you made to the page were not saved."}

});

/* List all buttons and controls you want to exclude warning message */

 $( "#Save").unbind('click').removeAttr('onclick').click(function(){

  $('#wwvFlowForm').data('htmldb',{'dirty':false});

  javascript:apex.submit('SAVE')

});

$( "#Submit").unbind('click').removeAttr('onclick').click(function(){

  $('#wwvFlowForm').data('htmldb',{'dirty':false});

  javascript:apex.submit('SUBMIT')

});

});

</script>

If you have problems with the buttons not being disabled,  you probably have a dynamic action in javascript.  These two javasripts can conflict with eachother.

Remove the script for the buttons that are not working and add this line to the javascript that is triggered when to the dynamic action for when button is pressed
This should fix your problem.

$('#wwvFlowForm').data('htmldb',{'dirty':false});
