YUI 3 'on'.js

// where...
someFunc = function(e) {
    // e has the event data
}

// I'm having a play with YUI 3 and came across an oddity.

Y.all('input').on('focus', someFunc);

// In the context of someFunc, 'this' is the set of inputs and
// not the specific input that gained the focus.

// Based on the documentation, this is the correct behaviour.

// I assume the way to work around this is:

Y.all('input').each(function () {
    this.on('focus', someFunc);
}

// … but I wonder if there is a nicer approach out there.

// You describe your problem. Ask the world. Think of a
// slightly different search term. Then find the answer.

// Via http://developer.yahoo.com/yui/3/examples/node/nodelist.html

Y.all('input').each(function (o) {
    o.on('focus', someFunc);
}

// if you want `this` in someFunc to be the element pass the element as context

Y.all('input').each(function (o) {
    o.on('focus', someFunc, o);
}
