Introduction
The setmultiplevariables widget assigns values to multiple variables where the names and values of the variables are specified as separate filter.
Content and Attributes
The content of the <$setmultiplevariables> widget is the scope for the value assigned to the variable.
| Attribute | Description |
|---|---|
| $names | Filter evaluating to the names of a list of variables to assign |
| $values | Filter evaluating to the values corresponding to the list of names specified in $names |
Examples
Here is an example of a convoluted way to display the values of the fields of the tiddler "HelloThere":
<$setmultiplevariables $names="[[HelloThere]fields[]addprefix[demo-]]" $values="[[HelloThere]fields[]] :map[[HelloThere]get<currentTiddler>]">
<ol>
<$list filter="[variables[]prefix[demo-]sort[]]">
<li>
''<$text text={{{ [<currentTiddler>removeprefix[demo-]] }}}/>'': <$text text={{{ [<currentTiddler>getvariable[]] }}}/>
</li>
</$list>
</ol>
</$setmultiplevariables>That renders as:
