ElementUISelect组件怎么默认选中？这些选项里面的数据都是动态抓取的，但是现在我需要让里面的某个选项被设为默认值。如果当前页处于用户编辑的情况下，我通过ajax获取到用户的这些参数之后，我要怎样将用户的参数在选项里被设为默认呢？附上js代码：<script>exportdefault{name:'edit',created(){this.$http.get('xxxxxx/api/getUserAttributes').then(resolve=>{this.departments=resolve.data.departmentsthis.userlevels=resolve.data.userlevelsthis.positions=resolve.data.positions},reject=>{this.$message.error('error')})letquery_id=this.$route.query.id?this.$route.query.id:30this.$http.get('xxxxxx/api/getUser',{params:{query_id:query_id}}).then(resolve=>{this.form.id=resolve.data[0].idthis.form.account=resolve.data[0].accountthis.form.password=resolve.data[0].passwordthis.form.nickname=resolve.data[0].nicknamethis.form.email=resolve.data[0].email},reject=>{this.$message.error('error')})},data(){return{form:{id:'',account:'',nickname:'',password:'',email:'',sex:1,authority:[]},departments:[],userlevels:[],positions:[]}}}</script>
