What are Hash Variables?
...
| English |
|---|
Hash variables in Joget are placeholders used to dynamically display data within applications. They allow users to insert dynamic content without hardcoding values, which enhances flexibility and customization. Hash variables can fetch and display data from various sources such as forms, workflows, and the system itself. They promote customization and flexibility by avoiding hardcoded values, ultimately improving the user-friendliness of Joget applications. |
A hash variable is a special hash-escaped keyword that can be used in :
...
| Name | Description |
|---|
| Prefix | userviewKey |
| Description | Userview Key Hash Variable is used solely for the purpose of accessing the current UI key's value. Typical use case for this hash variable are:- - Filtering a List based on UI Key.
- Preloading certain form data field (e.g. subform) in a Form or Form part of a process flow based on UI Key.

Expression Hash Variable
** for "datalist.col.xx.ID.column" variables, the "column" parameter refers to the order of the column in the list starting from 0. hence, to refer to the first column in a list called list_f1, your hash variable would look like this : #datalist.col.sum.list_f1.column_0
** the column are counted from 0, and does not include the default checkbox included in list tables

| Prefix | uiListCount |
| Description | The uiListCount hash variable is primarily utilized to retrieve the Datalist or Inbox menu count value. |
| Attributes | - #uiListCount.MENU_ID#
- #uiListCount.UI_ID.MENU_ID#
|
The uiListCount hash variable is primarily utilized to retrieve the Datalist or Inbox menu count value. |
| Attributes | - #uiListCount.MENU_ID#
- #uiListCount.UI_ID.MENU_ID#
|
| Scope of Use | - All components within the App except UI Permission.
| Warning |
|---|
uiListCount cannot be used inside UI permission. This is due to:
1. UI permission contains a uiListCount hash variable
2. uiListCount Hash requires UI to load to get the count
3. In order to load the UI design, the UI permission will be called. It goes back to step 1.
