<div>
 <template v-for="item in chks">
 <input type="checkbox" name="hobby" :value="item.id" 
 :checked="loopsss.indexOf(item.id) > -1"/>{{item.name}}

 :selected="loopsss.indexOf(item.id) > -1">{{item.name}}
 </option>

<script>
 export default {
 data () {
 return {
 chks: [
 {id:1,name:"吃饭"},
 {id:2,name:"睡觉"},
 {id:3,name:"打豆豆"},
 {id:4,name:"唱歌"},
 {id:5,name:"学习"}

 },
 mounted: function () {
 this.init()
 },
 methods: {
 init: function () {
 var arr = [1,2,4]//假设这是被选中的爱好
 this.loopsss = arr
