Comments on: Extending jQuery UI Widgets Revisited http://bililite.nfshost.com/blog/2008/08/13/extending-jquery-ui-widgets-revisited/ Thoughts on web design and programming from a very occasional volunteer webmaster Thu, 10 May 2012 10:36:28 +0000 hourly 1 http://wordpress.org/?v=3.3.2 By: Danny http://bililite.nfshost.com/blog/2008/08/13/extending-jquery-ui-widgets-revisited/comment-page-1/#comment-345 Danny Fri, 22 Aug 2008 22:18:20 +0000 http://bililite.nfshost.com/blog/?p=81#comment-345 @peschler: You're absolutely correct (I've updated it). slice starts at 0! I will admit, though, that in my own code I removed callSuper in favor of using apply directly: $.yi.superbox.prototype.move.apply(this, arguments) I think it's just as clear as this.callSuper('yi.superbox', 'move') and communicates better what is going on. It's more verbose, and I may change my mind. I wrote a recent <a href="/wordpress/2008/08/22/extending-jquery-ui-widgets-the-final-chapter/" rel="nofollow">post</a> on my most recent code. Thanks for the feedback! @peschler:

I will admit, though, that in my own code I removed callSuper in favor of using apply directly:
$.yi.superbox.prototype.move.apply(this, arguments)
I think it’s just as clear as this.callSuper(‘yi.superbox’, ‘move’)
and communicates better what is going on. It’s more verbose, and I may change my mind.

I wrote a recent post
on my most recent code.

Thanks for the feedback!

I'm currently using your code to create a wizard which derives from the ui.tabs widget and everything works like a charm! Thanks for saving me a lot of time. While using the callSuper() is spotted at bug - at least it did not work to call a superclass function with arguments until I corrected the following code: [code] var CallSuper = { callSuper: function(superclass, method){ // return superclass.prototype[method].apply(this, Array.prototype.slice.call(arguments, 3)); return superclass.prototype[method].apply(this, Array.prototype.slice.call(arguments, 2)); } }; [/code] That is: the slice should start at 2, otherwise the first argument will be sliced away. Hi,

great post. I’m currently using your code to create a wizard which derives from the ui.tabs widget and everything works like a charm! Thanks for saving me a lot of time.

While using the callSuper() is spotted at bug – at least it did not work to call a superclass function with arguments until I corrected the following code:
[code]
var CallSuper = {
callSuper: function(superclass, method){
// return superclass.prototype[method].apply(this, Array.prototype.slice.call(arguments, 3));
return superclass.prototype[method].apply(this, Array.prototype.slice.call(arguments, 2));
}
};
[/code]

That is: the slice should start at 2, otherwise the first argument will be sliced away.
