client script: set assigned to on change assignment group

[wc99]

Hi, I have a requirement, after select an assignment group, one of the members from the group should auto populate. If the assignment group field clear again, the assigned to field will be cleared also. I am new to ServiceNow, and any help is appreciate, thanks! 

function onChange(control, oldValue, newValue, isLoading, isTemplate) {  
         if (isLoading || newValue === '') {
                   return;
         }
        
         var gr = new GlideRecord('sys_user_grmember');
    
  gr.addQuery('group', g_form.getValue('assignment_group'));
         gr.query(function(_gr) {
                   if (_gr.next()) {
                          
        g_form.setValue('assignment_group', _gr.group.toString());
                   }
         });
}

Hi Viktor, thanks for your script, it managed to populate the group member in "Assigned to" field once select the "assignment group". However, if clear the "assignment group" field, the "assigned to" value is not clear.

Please advise thanks in advance.

you may try like,

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading) {
return;
}

if (newValue != ''){
var gr = new GlideRecord('sys_user_grmember');
gr.addQuery('group', newValue);
gr.query();
if (gr.next())
g_form.setValue('assigned_to', gr.user);
}else if (newValue == '') {
g_form.clearValue('assigned_to');
}

}

Try this

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading) {
return;
}

var gr = new GlideRecord('sys_user_grmember');
gr.addQuery('group', newValue);
gr.query();
if (gr.next()) {
g_form.setValue('assigned_to', gr.user);
}

if (newValue == '') {
alert(newValue);
g_form.setValue('assigned_to', '');
}

}
