//h2. General | |
//* Use $(function(){...}) instead of $(document).ready(); | |
//h2. Selectors | |
//* Prefix all jQuery variable with $ except in one case. (The exception is defined in the next point). This helps to remember that this variable is a jQ variable. | |
//* Name reference to the current element as e within a callback. eg. | |
$('.class').live('click', function(){ | |
var e = $(this); | |
//... | |
}); | |
//* Always cache the jQ variables. eg. | |
var $calendar = $('#calendar'); | |
var $someOtherElements = $('.className'); | |
$calendar.live('click', ...); | |
//* Use context if available. eg. | |
var $calendar = $('#calendar'); | |
var $cells = $('td', $calendar); | |
//h2. Chaining | |
//* If there are more than 3 events chained in the same call, split it up into separate lines. eg. | |
//* If the chaining touches upon more than one element then indent the calls as described in http://benjaminsterling.com/better-jquery-code-2/ | |
//h2. Events |
