Vue instruction 7:
- v-if conditions rendering instruction
- Bool value according to the expression thereafter determines whether the rendering element
- v-show
- And v-if similar, but it will render the elements behind the expression is false, and such elements will add css code: style = "display: none"
- V-else
- 必须跟在v-if/v-show指令之后，不然不起作用；如果v-if/v-show指令的表达式为true，则else元素不显示；如果v-if/v-show指令的表达式为false，则else元素会显示在页面上
- v-for
- 类似JS的遍历，用法为 v-for="item in items", items是数组，item为数组中的数组元素
- v-bind
- 这个指令用于响应地更新 HTML 特性，比如绑定某个class元素或元素的style样式，它的语法糖为 '：'
- v-on
- 用于监听指定元素的DOM事件，比如点击事件，它的语法糖为 '@'
- v-model
- 用于表单元素，进行双向数据绑定
