  Interstage BPM Studio Version: All versions of Interstage BPM Studio that supports Java Action Sets

  
  Introduction:
  This article will demonstrate how JavaScript can be used with Interstage BPM Studio to evaluate the difference between a date stored in a user defined attribute (UDA) and the current date.  This is just an example of how dates can be manipulated within Studio to trigger a specific outcome.
  
  
  Installation:
  In order to add JavaScript code that is compiled and ran during runtime, click on a node that supports Java Action Sets. Then, click on the Action Set > Add > Evaluate Script and add the JavaScript.
  

  The following sample script retrieves the current date and a date stored from a user defined attribute (UDA).  Then an evaluation is done to see if the difference between those dates is equal to or greater than 45 days.  Based on the outcome from the evaluation, a UDA of type Boolean is set to true or false.

  ********************************************************************
  // Get current date
  var date = new Date();

  // Convert current date into milliseconds
  var curDateToMilli = Date.parse(date);

  // Get date value from a UDA of type Date
  var endDate = uda.get("DateStored_UDA");

  // Convert UDA date value into milliseconds
  var endDateToMilli = Date.parse(endDate);

  // Find the difference between the UDA date and current date in milliseconds
  var dateDiff = endDateToMilli - curDateToMilli;

  // Now a comparison can be made to a predefined date (in milliseconds) to see if it meets a certain criteria.
  //  In this case, this comparison is to see if the difference is less than or equal to 45 days.  If yes, set the Boolean // type UDA, “conditionCheck” to “true”.  If no, then it is set to “false”.

  if (dateDiff <= 3888000000)
  {
  uda.set("conditionCheck", "true");
  }
  else
  {
  uda.set("conditionCheck", "false");
  }
