What is Hash Variable?
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.

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.
#prefix.{prefix.variableKey}#
#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.
