你好呀

<script>
    Vue.config.productionTip = false
    new Vue({
        el: '#root',
        data: {
            opacity: 1,
            name:'你好'
        },
        //Vue完成模板的解析并把初始的真实DOM元素放入页面后（挂载完毕）调用mounted
        mounted() {
            console.log('nhao')
            setInterval(() => {
                this.opacity -= 0.01
                if (this.opacity <= 0) this.opacity = 1
            }, 16)
        },
