How to remove a method of a widget ?

in Using jQuery UI • 12 years ago

Hi,

I'd like something simple I guess but I dunno how to do it. It's for the Accordion widget but it's the some for all widget.

Well, I'd like to destroy the _keydown method.

$.widget( "ui.accordion", {
_keydown: function( event ) {
// blah
},
// reblah
});

Well I want to kill it because I already have the keys UP and DOWN used for the navigation, it breaks it :(

Thanks.

It should be able to be done like this:

$.ui.accordion.prototype._keydown = function() {
// do nothing
}

You can't "remove" it since other parts of the widget will call it, but you can rewrite it do nothing as seen above.

Note, that is touching the prototype, so it will impact all instances of accordion. The following approach may target a specific instance. Please be aware that the following code is completely untested and is based on some code from an autocomplete demo (http://jqueryui.com/demos/autocomplete/custom-data.html).

$('some_selector').accordion(...)
.data( "accordion" )._keydown = function() { /* do nothing */ };
