String field should not allow special characters

vijay39 · ‎10-26-2018

Hi Guys,

I created a catalog item with few variables. In that i have a User name variable (of type String).

It should allow only letters but not special characters like @ # % ^ etc..

How can i do this?

Regards,

Vijay

function onChange(control, oldValue, newValue, isLoading, isTemplate) {


   if (isLoading || newValue === '') {


   return;


   }


   var regex = new RegExp("^[a-zA-Z0-9]*$");


   if(!regex.test(newValue)){


   alert('Incorrect username');


   g_form.setValue('u_user_name','');



   }


}
