You can pass a value, using normal YUI:

.on(”click”, this.getAlbums, value, this)

You can pass values w/ .apply & .call as well.

.apply:
func_name.apply(scope, singleArg)
func_name.apply(scope, [multiple, args])

.call
func_name.call(scope, singleArg)
func_name.call(scope, multiple, args)

Using scope correction in JS is pretty simple & super-useful.

Thanks. I’ve actually learned a lot about building widgets from visiting your site.

@admin:

Passing more argument along with the scope is a build-in feature in YUI3.x. You can emulate it on YUI2 using “apply”, but you have to do it manually, like your method “bindCallBack”.

Here is the YUI3 documentation:
http://developer.yahoo.com/yui/3/event/

Check the section: “Using on: Controlling Context and Arguments”.

Interesting. I wish I could also pass a value.

You can also write it as:

.on(“click”, this.getAlbums, null, this)

which I prefer. Also for regular JS scope-correction function.call and function.apply are very handy to know about.
