elementui el-select组件多选设置初始值无法修改问题

			<el-select v-model="form.optrList" multiple placeholder="请选择"><el-optionv-for="item in list":key="item.value":label="item.label":value="item.value"></el-option></el-select>...this.form.optrList = xxx;

使用this.$set对list进行赋值

this.$set(this.form, 'optrList', xxx);
