Question

我怎么监听innerHTML的修改何时渲染完成

Answer 1

vue面本身带两调函数：
`Vue.nextTick(callback)`数据发变化更新执行调
另`Vue.$nextTick(callback)`dom发变化更新执行调
栗：

...

• {{item}}
  

...

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(){
alert('数据已经更新')
});
this.$nextTick(function(){
alert('v-for渲染已经完')
})
}
}
})
