How to use one client script, on multiple variables, in a variable set?

ericgilmore · ‎10-10-2016

I have a Variable Set with 6 variables. Each single line text.

I have a simple Catalog Client Script thats supposed to be applied to the variable set, which checks if the values put in the fields are, 1) numbers and, 2) from (0 - 30).

But, I only know how to make it check ONE variable, so I'd have to create this script for the other 5 variables to get it to work properly for each. I don't want to do this.

function onChange(control, oldValue, newValue, isLoading) {
     if (isLoading || newValue == '') {
           return;
     }
   g_form.hideErrorBox('tlos_place1');
   var partNumber = g_form.getValue('tlos_place1');
   var numbervalid = /^([0-9]{1,2})$/;
   if (!(partNumber.match(numbervalid)) || partNumber > 30) {
   g_form.showErrorBox('tlos_place1','That entry isn\'t in the expected range \(0-30\). Please try again.',false);
   return;
   } else {
   g_form.hideErrorBox('tlos_place1');
   return;
   }
}

How do I get it to work for all the variables in the variable set w/o attaching the script to each individual variable manually?

OK,

Since I had to attach a onChange client script to each variable in the set anyway, I just went with:

function onChange(control, oldValue, newValue, isLoading) {

   if (isLoading || newValue == '') {

           return;

   }

       var num = isNaN(newValue);

       if (num || newValue > 30) {

               g_form.showFieldMsg('place1','That entry isn\'t in the expected range \(0-30\). Please try again.','error');

       } else {

               g_form.hideFieldMsg('place1', true);

       }

}

I think I might have had to create a global onLoad script for the Catalog Item in order to get it working the other way. Unfortunately, I don't have access to do that yet.

So rlatorre pretty much had my answer this time.

Thank you all!

In my opinion, Service Now should make it possible to have a list of fields in an onChange client script.

This would create a much cleaner codebase. The approach described here however, works very well.

Thanks!

If this answer was helpful, I would appreciate if you marked it as such - thanks!
