tabs

tabs.js

new joContainer([

tabContent = new joContainer([
new joTitle("Hello from tab1").setStyle({
    display: 'none'
}), new joTitle("Hello from tab2").setStyle({
    display: 'none'
})]),

new joFlexrow(
new joOption(["Video Info", "Related Videos", ]).selectEvent.subscribe(function (value) {
    for (i in tabContent.data) {
        tabContent.data[i].setStyle({
            display: 'none'
        });
    }
    tabContent.data[value].setStyle({
        display: 'block'
    });
}))

]),

This is a fine approach, though you might want to use joStack to push/pop views in which correspond to each "tab".
