How to get the value from sys_id in the client script?

[Murthy JN1]

Hi,

 I have an onLoad client script that displays the parent incident if we open a child. I am getting sys_id instead of the actual value. Please guide. 

This is the script:

function onLoad() {
if(g_form.parent_incident != '')
{ alert("This is hte parent of " +g_form.getValue('parent_incident'));  }}

Someone has taught me using GlideRecord is not a suggested practice in Clinet Scripts.  How to populate actual value instead of sys_id?

Hi,

You need to call a server side script (script include) to get the related value from the table.

Go through below examples to configure for the same.

Hi Murthy JN,

Please try below code.

function onLoad() {

if(g_form.getValue("parent_incident") != '')

var parentinc = g_form.getReference("parent_incident",getDetails());

}

function getDetails(parentinc)

{

alert(parentinc.number);

}

Please mark the response as Helpful/Correct, if applicable. Thanks!

Nikita,

        Thanks for your answer. It helped, but I think callback function should not have () while calling it.

        var parentinc = g_form.getReference("parent_incident",getDetails); should work.

Yes, it is not a best practice to use glide record on client script, so you can get the value by using client script it self..

Try the below On Load Client script.

function onLoad() {
var usr = g_form.getReference('giveparentfieldname',callBack);
 }
 function callBack(usr){
     alert(usr.number);
   }
}
