How to compare catalog reference variables

[chrish5]

I'm trying to compare two reference variables on a catalog item and if the second one matches the first one, alert the user of the duplication and clear the contents of the second variable.   First reference variable is new_site_owner and the second reference variable is new_site_owner2   Below is the catalog client script I am using woth Type: OnChange and Variable Name: new_site_owner2.       Is this the correct way to compare two reference variables?       Thanks

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

  if (!isLoading || newValue == '') {

        return;

  }

  if(newValue == g_form.getValue('new_site_owner')) {

          alert("Owners cannot be the same");

          g_form.setValue('new_site_owner', '');

    }

    }

Hi Chris,

Use the () after the toString since it is a function. I hope this would solve your issue.

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

              if (isLoading || newValue == '') {

      return;

  }

  if (g_form.getValue('new_site_owner2').toString() == g_form.getValue('new_site_owner').toString()) {

alert("The primary site owner and the secondary site owner cannot be the same person");

g_form.setValue('new_site_owner2', '');

  }

  }

You can also use the below condition if you writing onchange script on new_site_owner2 field.

if (newValue == g_form.getValue('new_site_owner').toString()) {

Pradeep. I am unable to access the demo site.   It's telling me System initializing, please check back later.   I was able to resolve this thru another community users suggestion.   Thank you for your time.

Thank you for providing this script. I was able to make this work to avoid having the same 2 people be selected for approvers. My question is how do I reverse the script? Meaning, I want an alert message to appear if two variables are not equal. I thought I could simply use the same script but replace (==) with (!=) but that did not work.
