title: Do nothing widget tutorial

In order to define a widget in a tiddler, the tiddler must satisfy these requirements:
|
||
|
|
|
||
|
|
* type field is application/javascript
|
||
|
|
* module-type field is widget
|
||
|
|
* the text field contains the javascript code
|
||
|
|
|
||
|
|
The [[donothing.js]] tiddler fulfills the requirements and its code looks like this:
|
||
|
|
{{donothing.js}}
|
||
|
|
That code does 2 key things:
|
||
|
|
|
||
|
|
* Imports the core Widget class ([[$:/core/modules/widgets/widget.js]])
|
||
|
|
* exports the class in an attribute with the name we want our widget to have (`donothing`)
|
||
|
|
|
||
|
|
Here's what it looks like:
|
||
|
|
{{Do nothing widget demo}}
|
||
|
|
And it worked. No error message this time.
|
||
|
|
|
||
|
|
''Exercise'': Modify [[donothing.js]] and [[Do nothing widget demo]] so the widget is named `noop` instead of `donothing`
