vue mounted中监听div的变化
<div style="width:200px;height:30px;background: #0e90d2" >{{$store.state.msg}}</div>
methods: {
fun(){
this.$store.dispatch('fun',this.checkedNames);
},
mounted(){
document.getElementById('list').addEventListener("DOMSubtreeModified", function(){
var he=document.getElementById('list').offsetHeight;
document.getElementById('list2').style.height=he+'px';
console.log(he);
}, false)
}
