[Vtigercrm-developers] How to detect field value change on Edit View Save?

[Alan Lord]

Thanks - I managed to work it out by looking at the nodelist of the 
element - this doesn't change before the save, e.g.:

> var initialVal = el.attributes.getNamedItem('value').nodeValue;
> var submitValue = jQuery(el).val();

But I have a bigger issue now.

I am triggering my custom validation on the 
Vtiger_Edit_Js.recordPresaveEvent trigger and using e.preventDefault() 
to stop the process.

But, if my custom validation passes and I try to either trigger this 
event again, or just submit the form, I get into a never ending loop of 
Presave, submit(), Presave, submit()...... :-(

Any ideas how to stop/work around this?

TIA

Al
