Dot Walking multiple levels using getReference.

[HrishabhKumar]

Can we dot walk more that 1 level using getReference in Client Script.

In my case I'm not able to do that, it is returning "undefined".

g_form.getReference('caller_id').manager.email

g_form.getReference('caller_id').department.name

Question:

1) Can we dot walk more that 1 level in getReference?

2) If yes, then how so? because in my case I'm getting undefined.

Hi @HrishabhKumar 

You are unable to dot-walk further than just the field on the table you getting the reference from.

Any further dot-walking would instead need to be done through GlideAjax and then passed back to the client.

Hi @HrishabhKumar ,

Actually you are using wrong syntax of g_form.getReference. Please check below script 

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

   //Type appropriate comment here, and begin script below  department
   var userref = g_form.getReference('caller_id', userLookup);
    function userLookup(userref) {
		alert("Name = " + userref.department);
        g_form.setValue('description', userref.department);
		g_form.update();
    }
   
}

Here you can get the sys_id of caller's department(if present) in alert.

Please mark my answer correct and helpful if this works for you

Thanks and Regards

Hi @Community Alums ,

Thanks for you response.

This not a wrong syntax, this is one of the way to use getReference. FYI you can use getReference in two ways 

1) without callback fucntion (Synchronous)

    g_form.getReference('caller_id').manager.email

2) with callback function (Asyncronous & Recommended)

    The one you specified in the reply.

But anyways my question was can we do multiple level dot walking using getReference() function. I'm already able to get the sys_id of manager using the Synchronous method, I'm looking for the email of the manager, for that we will have to dot walk 2 levels.

first caller_id.manger

second caller_id.manager.email

According to my knowledge and confirmation from @Allen Andreas , We can only do one level dot walking in getReference function.

I hope my doubt is clear to you now.

Thanks & Regards
