Vue如何获取下拉框中选中的value值和label值

let obj = {}
obj = this.allVillage.find((item) => item.id === this.paneOneForm.villageId)
this.paneOneForm.villageName = obj.name

<select class="select" v-on:change="indexSelect($event)" v-model="pcNum">
	<option v-for="(item, index) in pcArr" :key="index" v-bind:value="item.pcNum">{{ item.pcNum }}</option>
</select>

data() {
return {
pcNum:'PC20200924',
pcArr:[
{id:1, pcNum: 'PC20200924'},
{id:2, pcNum: 'PC20200925'},
{id:3, pcNum: 'PC20200926'}
],
 }
},
methods:{
indexSelect(e){
console.log(e)
console.log(e.target.selectedIndex) // 选择项的index索引
console.log(e.target.value) // 选择项的value，也就是v-bind:value 的绑定值，如果换成 v-bind:value="item.id",则打印的是 选中项的id
}
}

<select class="select select2" @change="classSelect($event)"  v-model="classs">
	 <option v-for="(item, index) in classsArr" :key="index" v-bind:value="item.name">{{ item.name }}</option>
</select>

data() {
 return {
classs:'',
classsArr: [{name: "蓝色妖姬", table: "bluerose"}, {name: "烟叶",table: "tobaccoleaf"},{name: "佛手瓜", ?table: "chayote"}]
 };
},
methods: {
classSelect(e){
var table=''
for (var i in this.classsArr) {
i=e.target.selectedIndex
table=this.classsArr[i].table
}
console.log(table)
},
}

<select class="select select2" @change="classSelect" ?v-model="classs">
 <option v-for="item in classsArr" :key="item.table" v-bind:value="item.table" :label="item.name"></option>
</select>

data() {
 return {
classs:'',
classsArr: [{name: "蓝色妖姬", table: "bluerose"}, {name: "烟叶",table: "tobaccoleaf"},{name: "佛手瓜", ?table: "chayote"}]
 };
},
methods: {
classSelect(){
console.log(this.classs)
},
}
