1、过滤器
配合moment.js 日期插件过滤时间, 非常方便

filters: {
    moment: function (data) {
    if (!data) return ''
    return moment(parseInt(data)).format('LL')
    }
}
<span>{{ date | moment }}<span/>

2、 v-if v-show

v-if 是“真正”的条件渲染，v-show 就简单得多基于 CSS 进行切换
如果频繁的切换元素，请使用v-show

3、避免 v-if 和 v-for 用在一起

v-for 的优先级大于 v-if
