Accessing plugin instance from DOM with data() broken

According to


When a plugin instance is created, it is stored on the original DOM element using, with the plugin name as the key.

Because the plugin instance is directly linked to the DOM element, you can access the plugin instance directly instead of going through the exposed plugin method if you want. This will allow you to call methods directly on the plugin instance instead of passing method names as strings and will also give you direct access to the plugin's properties.

var bar = $( "<div />")
    .appendTo( "body" )
    .data( "progressbar" );
// Call a method directly on the plugin instance.
bar.option( "value", 50 );
// Access properties on the plugin instance.
alert( bar.options.value );


That doesn't work at all.

$(domElement).data("pluginname") returns undefined.

Ok, figured it out. The plugin's fullname is needed, i.e. prefix-fullname.

There error therefore is in the abovementioned documentation page, not a bug in the widget factory itself.

It works as expected, but the example in the documentation wouldn't (it needs to be data("ndk-progressbar")).

Apparently I can't close this report myself, so please close it, I'll report it against
