Create Your Own Custom JavaScript Dollar Function To Select An Element
The "dollar" function has become famous in recent years due to its inception in many popular JavaScript frameworks. MooTools, for example, uses the dollar function to select a single element from the DOM. This functionality is extremely helpful as it allows you to keep your code extremely short and readable, not to mention document.getElementById(''); can get annoying quickly.
The Code
function $(id)
{
return document.getElementById(id);
}
You don't need to use a JavaScript framework to compact your code. If you frequently select unique DOM elements, you should create a dollar function for the sake of yourself and your users.
