Validating event before adding event

Discontinued products Scheduler for Mobile and Touch devices
#1

Hi,
I’m trying to add an event for validating the dates and that the event title won’t be empty before adding it.
But this code isn’t working for me.
Thanks

[code] $$(“scheduler”).data.attachEvent(“onBeforeAdd”,function(id){

				   var current_date = new Date();

				   if(this.item(id).start_date > this.item(id).end_date){
					  dhx.alert("Start Date should be less than End date");
					  return false; // event won't be saved, user can fix start date
				   }
				   if(this.item(id).start_date < current_date){
					  dhx.alert("Start Date with time should not be less than current date with time.");
					  return false;
				   }
				   
				   retrun true; // default action, event will be saved
			});[/code]

Also i would like to know how to limit the input boxes to 255 characters.
Just like in html:

How is this done?

maxlength property works for text view but not text area

Please see the similar post about validation:

There is not a built0in attribute maxLength for textarea. However, you may set it after textarea creation using getInput() method:

$$(“txtId”).getInput().maxLength = 10;

If you asked about “details” textarea in Scheduler, you need to call this method from the onAfterRender event handler as editForm is not rendered initially:

$$(“scheduler”).$$(“editForm”).elements[“details”].attachEvent(“onAfterRender”,function(){
this.getInput().maxLength = 10;
});
