What is Hash Variable?

titleDefinition
Hash Variables gives users greater flexibility and freedom in accessing useful information or relevant run-time values from the system.

A hash variable is a special hash-escaped keyword that can be used in :

  • Form Builder
  • Datalist Builder
  • Userview Builder
  • Supported plugin configuration properties
  • Activity name in Workflow Designer
  • External Form URL when mapping an activity to an external form

to return the value of some useful runtime variables from Joget components.

Tip
To conveniently access the list of all hash variables available, use shortcut combination Ctrl-Shift-3 in any of the components above.
Tip

Download the tutorial app on Hash Variables from Joget Workflow Marketplace to learn more about Hash Variable.

Nested Hash Variable

Since version 3.0.3, a Hash Variable can be used inside another Hash Variable to form a Nested Hash Variable.

The syntax for the inner Hash Variable is wrapped by a pair of curly bracket.

Code Block
languagejava
titleSyntax / Format
#prefix.{prefix.variableKey}#
Here's some examples:
Code Block
titleExample
#date.{envVariable.dateFormat}#
#user.{variable.username}.firstName#
#form.tableChild.field1[{form.tableParent.childId}]#

 

Escaping the Resultant Hash Variable

The parsed/returned Hash Variable may cause incompatibility with the current context/environment such as syntax error in a script. Therefore, one may pass in additional parameters into the hash variable declared to escape certain characters.

Before ending a hash variable with a hash "#", add a question mark character "?" followed by the required format. You may include multiple by defining semicolon ";" separated values.

  1. regex - Used to escape regular expression special characters
  2. json - Used to escape JSON special characters
  3. javascript - Used to escape Javascript special characters
  4. html - Used to escape HTML special characters
  5. xml - Used to escape XML special characters
  6. java - Used to escape Java special characters
  7. sql - Used to escape SQL special characters
  8. url - Used to escape URL special characters
  9. nl2br - Used to convert new line character to <br> HTML tag
  10. separator(SEPARATOR_CHARS) - Used to change the default separator ";" to the SEPARATOR_CHARS. eg. ?separator(, ) resulted "abc, def" instead of "abc;def".
Code Block
titleExample
#envVariable.script?java#
#envVariable.script?nl2br;json#
#form.table.users?separator(, )#
