Use of the toggle () function in jQuery _ jquery

I believe everyone knows about the toggle () function in jQuery very well. There are also many related tutorials on the internet. what I want to share with you today is toggle () in actual projects () for more information, see. Today I met an interesting example to record it.

A level-1 menu contains a level-2 menu, which links page elements through the anchor. When you click an anchor, the page is linked to the corresponding anchor, and the level-2 menu is hidden. click the level-1 menu to continue ..

It has tried a lot of methods, and finally implemented it by reading jquery's toggle function.

// Write $ (". nav "). toggle (function () {$ (". content "). slideToggle () ;}); // you cannot write $ (". nav "). toggle (function () {$ (". content "). slideDown () ;}, function () {$ (". content "). slideUp () ;}); // you can write $ (". nav "). click (function () {$ (". content "). toggle ("slow ");});
