[vue]html标签select会改变value类型？？都变成string了？

采用vue写法利用select取第二个值作为valuemodelValue类型为number|string

const data:[number|string,number|string][]= [[1, '肖明']，['测试', 1]，["id", 5]],

  <select :value="modelValue" @change="selectHandler($event)">
      <option v-for="(item, index) in data" :key="item[0]" :value="item[1]">
                {{ item[0] }}
       </option>
   </select>

js

const selectHandler = (e: Event) => {
    const val = (e.target as HTMLSelectElement).value //问题:不能获取到正确类型？
    //emits('update:modelValue', val)
}



一楼大哥详解可以！！
const modelValueRef = ref<number | string | undefined>()

 <select v-model="modelValueRef">
            <option v-for="(item, index) in enumStrsList" :key="index" :value="item[1]">
                {{ item[0] }}
            </option>
</select>
