Display help text conditionally in service portal

Annika Aaltonen · ‎05-20-2019

Hi,

I need to expand (alternatively display) the help text on variable A, when variable A has value X, and preferably also revert back when not true. I found this article:

https://community.servicenow.com/community?id=community_question&sys_id=7a24c329dbd8dbc01dcaf3231f9619c3&view_source=searchResult

but I can't seem to get it to work. Do I need to change some bit, since I need it for Service Portal UI?

Or has something changed since, it's a 2 yr old post?

Here is what I got from this post, please tell me what is wrong here:

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


     //Type appropriate comment here, and begin script below

var val =g_form.getValue('A');
if(val == 'X'){
 
var elems = document.getElementsByClassName('sc-help-text annotation-wrapper');
   for (var i=0;i<elems.length;i+=1){
 
   if (elems[i].style.display === 'none') {
   elems[i].style.display = 'block';
   }
 
   }
}
}

Or maybe nothing is wrong with my script, but something else I'm completely missing..

Thanks in advance!

I tried below script in my PDI and it works for me.

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }
if (newValue=='admin'){
	alert('test');
   g_form.showFieldMsg('type_of_request','This is a test','info',true);
}
	 else{
 g_form.hideFieldMsg('type_of_request');
 }
}

DOM manipulation is not supported in service portal. Please refer below link

Thanks! That explains it completely 🙂 Is there any smoother way to do this, than to display some sort of label variable with Cat. UI policy then?

Cheers,

Try using field message, if that helps your need.
