For developers: Avoid conflicts when loading multiple versions of jQuery
By default, Sitefinity CMS uses the built-in jQuery library (version 1.8.3). In some cases you may require a different version of jQuery to support a Javascript library written for a specific version. However, simply including a second version of jQuery may cause unexpected conflicts.
NOTE: To check the current version of jQuery, use the $.fn.jquery property.
To correctly include a version of jQuery that is different than the built-in version, you need to use the jQuery.noConflict() method to wrap your custom logic in a function scope and avoid conflicts:
var jq14 = jQuery.noConflict(true);
(function ($) {
$(document).ready(function () {
// your logic
});
}(jq14));
After loading a second version of jQuery, calling the jQuery.noConflict(true) method restores the globally scoped jQuery variables to those of Sitefinity’s built-in jQuery library. In the code above, the variable jq14 is passed to a function scope. Inside that function scope, Sitefinity’s version of jQuery is overridden and any code placed in the scope accesses the jQuery version you loaded.
