Syntax for text with embedded JavaScript

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

  • In scriptlets of script tasks in service flows.
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.
