Get value before .onChange()

How can I get the value of a textbox before onChange?
Here's my jsfiddle. Change the value in any of the checkboxes.

Thanks for any help you can provide.

You could store the old value in a data attribute on focus: http://jsfiddle.net/sb4ohdkj/16/
$('table#Prioritize').on('focus','input[type=text]',function(e){
    $(this).data('oldval', $(this).val());
});
$('table#Prioritize').on('change','input[type=text]',function(e){
    alert("New Value: "+$(this).val());
    alert("Old Value: "+$(this).data('oldval'));
});

Open in new window

Think about whether you want to keep the original or store the 'new old value' on subsequent edits.

try:
$('table#Prioritize').on('change','input[type=text]',function(e){
	if(!this.oldValue)
  	{
             this.oldValue = this.defaultValue;
         }
    alert("Old Value: "+$(this).prop('oldValue'));
    alert("New Value: "+$(this).val());
    //update the "oldValue" with the "current value" so that on the next change it will be seen as "old"
    this.oldValue=this.value;
});

Open in new window
