It's an input field and you already have a reference to it, there is
no need to use the $ function:
var inputValue = this.value;

If the condition is true, it has already returned so there is no need
for an else branch. The statements for the false condition just follow
the if block.

The focus method belongs to the input, there is no need to use the $
function:
this.focus();

That is a really good way to annoy your users (see TJ's post). To get
it to "work", use setTimeout to call the focus method:
var el = this;
window.setTimeout(function(){el.focus()}, 0);
But I don't recommend doing that.
