[jQuery] extending objects with jquery

[Javier Martinez]

I'm moving from mootools to jquery and trying to port my UI framework
to jquery.
Some of my widgets are extending from another widget. For example a
"datagrid" and a "dataview" objects extends from "view" object
(because both uses same methods from view).
With Mootools I have something like this

Class View()

Class DataGrid ({
extends: View
})

Class DataView({
extends: View
})

What is the equivalent on jQuery?

Thanks!
