[Vtigercrm-developers] Update the value="x" in data-validation-engine attribute?

[Alan Lord]

With the Quick Create Calendar I have some Javascript code which is 
updating the start and end date and time fields based on some user 
specifics...

I can get the fields to update as required but what I can't work out how 
to do is to get the value in the data-validation-engine attribute itself 
to update.

> <input ...  data-validation-engine="validate[ required,funcCall[Vtiger_Base_Validator_Js.invokeValidation]]" name="time_end" value="10:44:21" class="timepicker-default input-small ui-timepicker-input" data-format="12" id="Calendar_editView_fieldName_time_end" autocomplete="off">

The field changes fine and I am trying to trigger an onchange event

e.g. endTimeEl.val(newTime).trigger('change');

but I can't work out what is responsible for updating that value 
_inside_ the data-validation-engine attribute...


TIA
