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.

Or, you can go to "Type Specifications" and uncheck "Include none".

Hi Jim,

That's the article I was looking for, I had a similar requirement in my project need you help.

writing the below as UI Script

replaced variable name with name of the variable where --None-- need to be replaced.

Having a doubt what else needs to be changed to make this work.

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

writing the below onLoad catalog Client script in Catalog Item

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