For the use of the toggle () function in jQuery, jquerytoggle

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 in this way
$ (". Nav"). toggle (function (){
$ (". Content"). slideToggle ();
});
// This cannot be written.
$ (". Nav"). toggle (function (){
$ (". Content"). slideDown ();
}, Function (){
$ (". Content"). slideUp ();
});
// You can write the code in this way.
$ (". Nav"). click (function (){
$ (". Content"). toggle ("slow ");
});
