What is Hash Variable?

Definition

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.

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

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.

Syntax / Format

#prefix.{prefix.variableKey}#

Here's some examples:

Example

#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.

regex - Used to escape regular expression special characters
json - Used to escape JSON special characters
javascript - Used to escape Javascript special characters
html - Used to escape HTML special characters
xml - Used to escape XML special characters
java - Used to escape Java special characters
sql - Used to escape SQL special characters
url - Used to escape URL special characters
nl2br - Used to convert new line character to <br> HTML tag
separator(SEPARATOR_CHARS) - Used to change the default separator ";" to the SEPARATOR_CHARS. eg. ?separator(, ) resulted "abc, def" instead of "abc;def".

Example

#envVariable.script?java#
#envVariable.script?nl2br;json#
#form.table.users?separator(, )#

New Feature

nl2br and separator are new features in Joget Workflow v6.
