In order to check whether a field value contains a particular word or not ,We can use indexOf method.

Solution:

var trackingNumber = ifRec.getValue({ fieldId: ‘tracking_number’ });

var index = trackingNumber.indexOf(“PRO#”);

 if(index != -1){

 alert(“PRO# found”); 

} else

{ 

alert(“PRO# not found!”);
