这样获取的数据是错误的！<body> <div class="container"> <div class="img-box" ref="box"> <img :src="url"> </div> </div> <script type="text/javascript"> var vm = new Vue({ el: '.container', data: { url: 'img/logo.png' }, methods: { getHeight () { let dom = this.$refs.box; console.log('1:' + dom.offsetHeight) // 21 or 22 } }, mounted () { this.getHeight(); } }); Vue.nextTick(function(){ console.log('2:' + vm.$refs.box.offsetHeight) // 21 or 22 }) </script></body>请问有没有办法获取？？？
