Drupal 7: JavaScript
Einige Tips für die Arbeit mit jQuery in Drupal:
It’s best practice to wrap your code in a closure. A closure is nothing more than a function that helps limit the scope of variables so you don’t accidentally overwrite global variables.
A closure can have one other benefit, if we pass jQuery in as a parameter we can map it to the $ shortcut allowing us to use use $() without worrying if jQuery.noConflict() has been called.// We define a function that takes one parameter named $. (function ($) { // Use jQuery with the shortcut: console.log($.browser); // Here we immediately call the function with jQuery as the parameter. }(jQuery));
