[Vue.js] Toggle (Show/Hide) HTML Element

Learn to toggle (Show/Hide) HTML DOM element is my favorite exercise for using a new JavaScript framework/library or compile-to-JavaScript languages such as GopherJS.

Demo

The following is key points in the code:

Use boolean variable isShow to control the visibility of DOM element.
When users click on the element with class name control (line 15~17), isShow = !isShow expression will make isShow become true if it is false, become false if it is true.
The element with class name content (line 18) will display or disappear by v-show directive and true/false of isShow.
