Definition and Usage

$ .sub () Function creates a new copy of jQuery, its properties and methods can be modified without affecting the original jQuery object.


Note: 1. From the start jQuery1.7 obsolete in jQuery 1.8 version will be moved to a plug-in.
2. $ .sub () does not try to do any form of isolation. All copies of jQuery still points to the original method of jQuery. (For example, will still be carried out by the original jQuery event bindings and triggers, data will be bound to the element .Ajax requests and events are also run by the original jQuery, etc. from the original jQuery.)
