In certain situations, you can combine literal text with parts that are computed dynamically.

  • In scriptlets of script tasks in service flows.
  •  Traditional:  In the definitions of web service servers in the process application settings.
The way to do this is through pieces of literal text, with interspersed parts in JavaScript. The syntax is as follows:
  • Normal text is taken literally, including newlines.
  • Use the syntax <#= expression #> to evaluate a JavaScript expression. The string representation of the result of the evaluation is spliced into the resulting text. For example, <#= 5 + 7 #> produces the string "12". The expression can span multiple lines if it is parenthesized.
  • Use the syntax <# statement #> to evaluate a JavaScript statement. The statement can span multiple lines; in this case, the normal rules for JavaScript end-of-line apply, as described in the section "Whitespace and semicolons" in the Wikipedia topic JavaScript syntax.
    To specify conditional statements, use the following syntax: 
    <# if (tw.local.foo  < 100) { #>TEXT A <# } else { #>TEXT B <# } #>
    In this example, either TEXT A or TEXT B will be part of the result, but not both. Note: You can only specify the parts #>TEXT A<# and #>TEXT B <# in places where, in JavaScript, a statement is allowed.
