vue中nextTick和$nextTick的差别

 

<ul id="demo">
    <li v-for="item in list">{{item}}</div>
</ul>
<script>
new Vue({
    el:'#demo',
    data:{
        list=[0,1,2,3,4,5,6,7,8,9,10]
    },
    methods:{
        push:function(){
            this.list.push(11);
            this.nextTick(function(){
                console.log('数据已经更新')
            });
            this.$nextTick(function(){
                console.log('v-for渲染已经完成')
            })
        }
    }})
</script>

 

 

 

 

* `Vue.nextTick(callback)`，当数据发生变化，更新后执行回调。
* `Vue.$nextTick(callback)`，当dom发生变化，更新后执行的回调。
