Client Script Help.

Hi All,

I have been tasked with creating an alert (or not) on load and on change.

 Under the Restaurant Field:

I would like an alert that references another field in the Location information. I have the following:

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

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

      return;

   }

   //Type appropriate comment here, and begin script below

g_form.showFieldMsg('u_restaurant', 'Current Trial:'  + ' ' + getValue('u_restaurant.u_choice_3'), 'info');

}

but this is returning 'Null'

I'm not trained in SNow and pretty much wing it with the help of community articles and google, but this time i cannot see a solution.

thanks in advance

Hi @Steven_4rcher 

May you try this

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

var trialValue = g_form.getValue('u_choice_3');

g_form.clearMessages();
g_form.showFieldMsg('u_restaurant', 'Current Trial: ' + trialValue, 'info');
}

thanks for the prompt reply, This unfortunately returned nothing.

maybe i should have mentioned the U_Restaurant field on the Incident table references the 'location' table. U_Choice_3 is a field in the location table:

I edited your script to return just the u_Restaurant field (I figured if i could get it to mimic the restaurant field i could work from there)

var trialValue = g_form.getValue('u_Restaurant');

and the message returned:

@Steven_4rcher 

if u_choice_3 is a field in the table being referred by Restaurant field then this script will work

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

    g_form.hideFieldMsg('u_restaurant');

    var ref = g_form.getReference('u_restaurant', callBackMethod);
}

function callBackMethod(ref) {
    if (ref.u_choice_3)
        g_form.showFieldMsg('u_restaurant', 'Current Trial:' + ' ' + ref.u_choice_3, 'info');
}

If my response helped please mark it correct and close the thread so that it benefits future readers.
