1, jQuery.Deferred exception: Cannot read property "addClass" of undefined TypeError: Cannot read property" addClass" of undefined

2, jQuery.Deferred exception: $. Cookie is not a function TypeError: $. Cookie is not a function

the js navigation bar scrolls to increase the number of errors reported by class. Ask God for guidance:

1. The first mistake is because you did not introduce jQuery.cookie.js
2. The second error is because the element calling addClass does not exist
