Javascript Shorthand for getElementById

Question

Is there any shorthand for the JavaScript document.getElementById? Or is there any way I can define one? It gets repetitive retyping that over and over.

Answer 1

var $ = function( id ) { return document.getElementById( id ); };

$( 'someID' )

Here I used $, but you can use any valid variable name.

var byId = function( id ) { return document.getElementById( id ); };

byId( 'someID' )
