el-select如何获取下拉框选中label和value的值

<templete slot-scope="scope">
<el-form-item :prop="'list'. + scope.$index + '.goodModularId'">
<!-- change事件中，会获取到当前选中的值（因为默认会将event参数传递过去;
如果想要传递多个值，change($event, "传递的其他值")，将“选中的当前元素” 和 “传递的其他值” 一起传递过去 -->
<el-select v-model="ruleForm.goodModularId" @change="getModularValue($event, scope.$index)" @clear="delModularValue(scope.$index)">
<el-option v-for="(item,index) in modularData" :key="index" :value="item.id" :label="item.name"></el-option>

getModularValue(val,index) {
