How to set outside variable value from inside client script of MVRS

Kalpesh Patil — Mon, 13 Apr 2026 09:11:31 GMT

I am attempting to set the value of a variable outside a Multi‑Row Variable Set from a client script within the MRVS. However, this is not working.

The requirement is to update an outside variable when a specific variable inside the MRVS changes.

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

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

return;

}

//g_form.setValue('in_domain', 'false');

var email=g_form.getValue('u_email');

alert(email);

var domain = email.split('@')[1];

alert(domain);

var ga= new GlideAjax('getDomain');

ga.addParam('sysparm_name','compareDomain');

ga.addParam('sysparm_dom',domain);

ga.getXMLAnswer(function (response) {

alert(response);

if (response !== 'true') {

alert('domain is not approved');

} else {

alert('domain is approved'); // getting this alert

g_form.setValue('in_domain','true'); // This is outside variable

}

});

//Type appropriate comment here, and begin script below

}

Hi @Kalpesh Patil

Can you try using this.

g_service_catalog.parent.setValue('field','value');

parent.setValue('field','value');

@Kalpesh Patil

I believe you can access outside variable within MRVS client script but not set it

you can check if row is added/removed and then based on that handle the logic to set outside variable

check this

MRVS detect when a row is removed or deleted
