How to hide the fields in the mrvs using client scripts

Recently I got to know about 

g_form.getValue(g_form.getDisplayBox('field_name’).id)

Not sure how it works.

and also how to get/set values field values which are outside the mrvs to set those field values to MRVS vice versa.

Hi @pk2184046, 

Hope you are doing well.

Proposed Solution

Q - How to hide the fields in the mrvs using client scripts?

A - As a solution, you can hide/show the fields of an MRVS using "Catalog Client Script" as well as "Catalog UI Policy". You just need to create any one of the two and Applies to "Catalog Item/Variable Set" depending on the requirement and condition you will have. Attaching scripts and snapshots for the reference.

On-Change Catalog Client Script: - Use Case - Hide Short Description Field if Logged-In User != Current user

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    if (newValue != g_user.userID) {
		g_form.setMandatory('u_short_description', false);
        g_form.setDisplay('u_short_description', false);
    }
	else{
		g_form.setMandatory('u_short_description', true);
		g_form.setDisplay('u_short_description', true);
	}
}

Output: -

Catalog UI Policy: - Use Case - Hide Short Description Field if a Caller Field is Empty.

Output: -

Hi @tushar_ghadage 

Use the below script and try

unction onLoad() {

   //Type appropriate comment here, and begin script below

   var choice_type = g_service_catalog.parent.getValue('this_inquiry');

   alert('choice_type'+choice_type);

   if(choice_type == 'new_server')

   {  

     g_form.setDisplay('origin',true);

   }    

}

Hi the solution is accepted if the MRVS variable is a select box.

What if the variable is a reference or a lookup variable in that it does not work correct.

Using client scripts I think it canbe achieved,by sys_id

Please provide me the solution
