element-ui 之 select 获取key和label

element-ui 之 select 获取key和label

element 获取下拉框的key和label,  ---------个人理解: 这东西做的官方做的思考不全

01)使用循环
02) 使用 proxy.$refs 获取

<template>
  <div>
    <h3>下拉框 获取key和label</h3>
    <p> const {proxy} = getCurrentInstance(); </p>
    <el-select v-model="feiVal" ref="feiRefs"  @change="handleChange">
      <el-option
          v-for="item in [{value: 'da', label: '大'},{value: 'fei', label: '飞'}]"
          :key="item.value"
          :label="item.label"
          :value="item.value"
      />
    </el-select>
  </div>
</template>

<script setup>
import {ref, getCurrentInstance, nextTick} from "vue";
const {proxy} = getCurrentInstance();

const feiRefs = ref();
const feiVal = ref(undefined);
const handleChange = (val) => {
  console.log("下标值__",val);
  // 01) 使用循环遍历
  // 02) 使用 proxy.$refs 获取
  nextTick(()=>{
    console.log("获取key和label",proxy.$refs.feiRefs.selected);
    console.log("获取label",proxy.$refs.feiRefs.selectedLabel);
  })
}
</script>
