! Introduction
The ''action-setfield'' widget is an [[action widget|ActionWidgets]] that assigns a value to a specified field of a tiddler. ActionWidgets are used within triggering widgets such as the ButtonWidget.
See also the ActionSetFieldsWidget (note the extra "s") that provides a more flexible way to set the value of a single field.
! Content and Attributes
The ''action-setfield'' widget is invisible. Any content within it is ignored.
|!Attribute |!Description |
|$tiddler |The title of the tiddler whose fields are to be modified (if not provided defaults to the [[WidgetVariable: currentTiddler]] |
|$field |The name of the field to be modified. If neither a field or index is specified, then the default field "text" is used |
|$index |If $field is not provided, specifies the index of a [[data tiddler|DataTiddlers]] to modify |
|$value |The value to be assigned to the field or index |
! Examples
Here is an example of a button that opens the control panel directly to the "Appearance" tabs:
<$macrocall $name='wikitext-example-without-html'
src='<$button>
<$action-setfield $tiddler="$:/state/tab-1749438307" $field="text" $value="$:/core/ui/ControlPanel/Appearance"/>
<$action-navigate $to="$:/ControlPanel"/>
Go to Control Panel "Appearance" tab
</$button>'/>
