javascript - Validate field/attribute in CRM Dynamics forms using js -

-

i have problem in validating attribute on form in crm dynamics. added javascript code validate attribute value based on business rules. , added 2 events, form on save , field on change,

the question is:

1- best way validate on attribute?

2- in case of using way, how can stop saving form or passing valid ?

i believe that's way validate input. in case want stop save in case 1 of validations fails following:

  1. check "pass execution context" during registration of save event handler.
  2. add parameter function that's called during save procedure.

  3. in case validation fails call following code:

    execobj.geteventargs().preventdefault()
