给需要获取label值的select取一个名字 ref="itemSelect"
<el-select placeholder="请选择项目" ref="itemSelect" size="small" v-model="projectId">
<el-option
:key="item.pkId"
:label="item.parentName '-' item.iteamName"
:value="item.pkId"
v-for="item in projectData"
></el-option>
</el-select>
通过名字获取选中option的label值,如果此方法失效,可打印此对象this.$refs.itemSelect
,查找选中项的label值
this.$refs.itemSelect.selectedLabel
