1.需求: 用户可自由选择需要修改的对象并同时修改多个属性,需要校验修改对象不能重复选择,但是可供修改属性是固定的
2.目标效果:
1.主要代码:
<template>
<el-select
v-model="selValue"
:size="$attrs.size"
placeholder="请选择"
@change="canidateChange(scope)"
>
<el-option
v-for="(selc, index) in SelectColumns"
:key="index + selc.item.key"
:label="selc.item.title"
:value="selc.item.key"
:disabled="selc.item.disabled"
></el-option>
</el-select>
</template>
<script>
export default{
name:"",
data(){
const SelectColumns = [
{

},
methods:{
