问题：当el-select下拉组件设置filterable属性时，下拉框展开后，再点击箭头图标下拉框收不回去了

解决方法：
在el-select标签上新增事件 @visible-change=“selectVisibleChange” @focus="selectFocus"的处理

<el-select v-model="condition.eq.userId"placeholder="选择操作员"filterable ref="selectTarget" @visible-change="selectVisibleChange" @focus="selectFocus"><el-optionv-for="(item, index) in userList":key="index":label="item.username":value="item.userId"></el-option></el-select><script type="text/javascript">
export default {name: "Index",data() {return {selectVisible:false}},methods:{selectVisibleChange(val) {setTimeout(() => {this.selectVisible = val}, 0)},selectFocus() {if (this.selectVisible) {this.$refs.selectTarget.blur()}}}
};
</script>
