Dynamic content as input for scripts

For scripts you can use some JavaScript objects and functions to generate dynamic input. Examples of this are random numbers, random string of a certain length, incremental numbers, and so on.

The way to do that is to use the next format in the input of a variable:

Native Javascript functions

You can use all the native JavaScript functions


  • mixing custom function and Javasript lib – <#= Math.round(libs.util.randomNumber(0, 1000) * 100)/100 #>
  • using string functions – <#= libs.util.randomText(34).toUpperCase() #> or <#= libs.util.randomText(34).concat(” “, “World!”) #>
  • using string functions directly – <#= “Please visit Microsoft!”.replace(“Microsoft”,”You-get”) #>
  • mathematic formula –  (1*2 + 5) / 7 == 1
  • using array functions – [40, 100, 1, 5, 25, 10].sort(function(a, b){return a – b});

Specific functions

There are some specific functions you can use, for this you use the format:

Random, date and time functions

  • <#=libs.util.randomNumber(min, max)#> – Random number in a range
  • <#=libs.util.randomNumbers(min, max, len)#> – List of random numbers. In a range and number of items.
  • <#=libs.util.randomInt(min, max)#> – Random integer in a range
  • <#=libs.util.randomInts(min, max, len)#> – List of random integers in a range, number of items.
  • <#=libs.util.randomString(len)#> – String of random characters, including numbers (length)
  • <#=libs.util.randomStringNum(len)#> – String of random numbers (length)
  • <#=libs.util.randomText(len) – String of random text (length) – Only text, no numbers
  • <#=libs.util.randomBirthday ()#> – Random date
  • <#=libs.util.currentDate()#> – Now
  • <#=libs.util.currentTime()#> – Now

Specific Dutch functions

  • <#=libs.util.randomBSN()#> – Random Social number (NL)
  • <#=libs.util.randomLHNR()#> – Random tax number for Dutch companies (concerning salary) (NL)
  • <#=libs.util.randomIBAN()#> – Random bank account number (NL)
  • <#=libs.util.randomVAT()#> – Random VAT number (NL)

Incremental number functions

  •  Increment.number(batchid, start, margin, reset) – incrementing number with steps
    <#=libs.util.Increment.number(“Counter1”, 0, 1, false)#>

“Counter1”, make this a unique as you can.
Reset: true -> starts with start again, false -> continues from previous
The counter is saved in the DB, so it will continue to increment.

  • Increment.numbers(start, margin, len) – create a list of numbers
    <#=libs.util.Increment.numbers(0, 10, 5)#>

From 0 with steps of 10 incrementing, creating a list of 5 items.

Note that this will work for

  • Individual variables
  • Within Complex business objects
  • Via data sheet input
