JQuery.noConflict ([removeAll])

Description: relinquish jQuery control of the $variable.

Added version: 1.0jQuery.noConflict ([removeAll])

RemoveAll

Type: Boolean

A Boolean value that determines whether to remove all jQuery variables (including jQuery itself) from the global scope.

Many javascript libraries use $as a function or variable name, just as jquery does. Under jQuery, $is just an alias for jQuery, so all functions are valid without using $. If we need to use both jQuery and other javascript libraries, we can use $.noConflict () to give control of $to other libraries. The $of the old reference is saved in the initialization of jQuery; noConflict () simply restores them.

If, for some reason, two versions of jQuery are loaded (which is not recommended), calling $.noConflict (true) in the second version returns the global jQuery variable to the first version.

Here is a technique that is particularly effective in resolving conflicts. The .ready () method can give an individual name to the jQuery object so that you can continue to use $inside the callback function passed to .ready () without worrying about conflicts (note: reason:. Ready () is a closure):

$.noConflict ()

JQuery (document) .ready (function ($) {
