如图所示,在项目开发过程中,遇到这样一个需求,常规时段中选中的月份在高峰时段中是禁止选择的状态,反之亦然。
// hooks/useMonth.js
export default function () {
const monthOptions = [
{
value: 'January',
label: '1月',
disabled: false,
},
{
value: 'February',
label: '2月',
disabled: false,
},
{
value: 'March',
label: '3月',
disabled: false,
},
{
value: 'April',
label: '4月',
disabled: false,
},
{
value: 'May',
label: '5月',
disabled: false,
},
{
value: 'June',
label: '6月',
disabled: false,
},
{
value: 'July',
label: '7月',
disabled: false,
},
{
value: 'August',
label: '8月',
disabled: false,
},
{
value: 'September',
label: '9月',
disabled: false,
},
{
value: 'October',
label: '10月',
disabled: false,
},
{
value: 'November',
label: '11月',
disabled: false,
},
{
value: 'December',
label: '12月',
disabled: false,
},
]
//把方法和数据返回出去
return {
monthOptions,
}
}
<template>
<el-select v-model="peakMonth" multiple placeholder="请选择月份" @change="handleMonth">
<el-option v-for="month in monthOptions" :key="month.value" :label="month.label"
:value="month.value" :disabled="month.disabled" />
</el-select>
</template>
<script setup>
import { reactive, ref, watch } from 'vue'
//引入hooks文件
import useMeasurementCommon from "@/hooks/useMeasurementCommon"
const { monthOptions } = useMeasurementCommon()
// 处理月份选择的回调
let monthsArr = ref([])
const handleMonth = (month) => {
console.log(month)
monthsArr.value.push(...month)
console.log(monthsArr)
console.log(monthOptions)
monthOptions.forEach(item => {
if (monthsArr.value.indexOf(item.value) !== -1) {
item.disabled = true
} else {
item.disabled = false
}
})
}
