Changing "-- None --" in Select Box variables on catalog items

[Jim Coyne]

There is a feature available to change the display value of the "-- None --" option in Select Box fields on forms. Here's the Wiki article - http://wiki.service-now.com/index.php?title=Customizing_Choice_Lists#Changing_the_--_None_--_Display_Value

However, that does not work with Catalog Variables. I created a UI Script that does it for you:

function u_replaceSelectBoxNoneString(variableName, newString) {
  try{
    var control = g_form.getControl(variableName);
    control.options[0].text = newString;
  }
  catch(err) {}
}

So now you can just call it from an onLoad script to change the string:

function onLoad() {
  u_replaceSelectBoxNoneString('action', '-- Please Select --');
}

and you end up with:


Bonus - It actually works on forms as well.

Just setting this answer as correct as the actual thread was not meant as a question and it cannot be changed because it came from the original Community site.

I know it's a lot of circular linking, but in case anyone finds only this page, I think it's worth also considering UI Messages for a possible global change: Re: Changing display value of --None-- for Service Catalog variables

(I've actually only used the NULL override approach so far, so I can't speak for exactly how "global" the change really is.)

Hello everyone,

Just to provide an update concerning this, the choice value must now be set to NULL_OVERRIDE. Choices with a value of NULL were not being properly saved, from my experience.

Reference: Change the None display value (also works on Helsinki)

Hi Trevor, seeing this post...any idea if this works for catalog items in Service Portal?
