How to iterate through regular single line text variables in an onChange Client script?

[Lon Landry4]

Hi Developer Community,

The script below is a working example of what I am trying to do.

The actual code will contain hundreds of variables.

So, I need to come up with a way to iterate through regular single line text variables in an onChange Client script.

My best guess is that I will need to turn the variables into an array by wrapping in brackets [ ].

But, I am not sure how the JSON would look or what to do after creating the array...

Any ideas?

//Working Script

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

   if (isLoading || newValue == '') {

      return;

   }

// List of variables being compared

    var aTag1 = g_form.getValue('first_asset_tag');

    var srlNbr1 = g_form.getValue('first_serial_number');

    var macAdd1 = g_form.getValue('first_mac_address');

    var aTag2 = g_form.getValue('second_asset_tag');

    var srlNbr2 = g_form.getValue('second_serial_number');

    var macAdd2 = g_form.getValue('second_mac_address');

    var aTag3 = g_form.getValue('third_asset_tag');

    var srlNbr3 = g_form.getValue('third_serial_number');

    var macAdd3 = g_form.getValue('third_mac_address');

//Match variables from list above to look for duplicate values

    if (macAdd3 == aTag1  ||macAdd3 == srlNbr1 || macAdd3 == macAdd1 || macAdd3 == aTag2

|| macAdd3 == srlNbr2 || macAdd3 == macAdd2 || macAdd3 == aTag3 || macAdd3 == srlNbr3){

    alert('Duplicate');

    g_form.clearValue('third_mac_address');

}

}

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }
   
   // Define the list of variables being compared
   var variables = [
       { assetTag: 'first_asset_tag', serialNumber: 'first_serial_number', macAddress: 'first_mac_address' },
       { assetTag: 'second_asset_tag', serialNumber: 'second_serial_number', macAddress: 'second_mac_address' },
       { assetTag: 'third_asset_tag', serialNumber: 'third_serial_number', macAddress: 'third_mac_address' }
   ];

   // Iterate through each set of variables
   for (var i = 0; i < variables.length; i++) {
       var currentVar = variables[i];
       var assetTag = g_form.getValue(currentVar.assetTag);
       var serialNumber = g_form.getValue(currentVar.serialNumber);
       var macAddress = g_form.getValue(currentVar.macAddress);

       // Check for duplicate values
       if (newValue == assetTag || newValue == serialNumber || newValue == macAddress) {
           alert('Duplicate');
           g_form.clearValue(currentVar.macAddress);
           break; // Exit loop once a duplicate is found
       }
   }
