這篇文章主要介紹了Avue和Element-UI動(dòng)態(tài)三級(jí)表頭如何實(shí)現(xiàn)的相關(guān)知識(shí)，內(nèi)容詳細(xì)易懂，操作簡單快捷，具有一定借鑒價(jià)值，相信大家閱讀完這篇Avue和Element-UI動(dòng)態(tài)三級(jí)表頭如何實(shí)現(xiàn)文章都會(huì)有所收獲，下面我們一起來看看吧。
需求場景： 業(yè)務(wù)方希望有表格可以體現(xiàn)員工的考勤信息，要具體到上午下午，統(tǒng)計(jì)司機(jī)上下班打卡所產(chǎn)生的數(shù)據(jù)。產(chǎn)品提出想做成三級(jí)表頭根據(jù)頁面查詢條件的年月去動(dòng)態(tài)生成表格的表頭。三級(jí)分別是月份日期，對(duì)應(yīng)的星期，以及每天的上午以及下午。
效果如下：
通過對(duì)avue-crud組件的option的配置如下：
{
label: `${$this.month}月${$this.dateList[0].ri}日`, // 月份
headerAlign: 'center',
children: [
{
label: `星期${$this.dateList[0].xq}`,
headerAlign: 'center',
children: [
{
label: '上午',
prop: 'oneAmAttendance',
headerAlign: 'center',
props: { label: 'name', value: 'code' },
type: 'select',
dicData: $this.attendanceTypeList,
formatter: (row, value, label, column) => {
try {
let satData = ''
$this.attendanceTypeList.find((item) => {
if (item.code === row.oneAmAttendance) {
satData = item.name
}
})
return satData
} catch (e) {
console.log(e)
}
}
},
{
label: '下午',
prop: 'onePmAttendance',
headerAlign: 'center',
props: { label: 'name', value: 'code' },
type: 'select',
dicData: $this.attendanceTypeList,
formatter: (row, value, label, column) => {
try {
let satData = ''
$this.attendanceTypeList.find((item) => {
if (item.code === row.onePmAttendance) {
satData = item.name
}
})
return satData
} catch (e) {
console.log(e)
}
}
}
]
}
]
},在data中聲明需要的變量以及獲取每個(gè)月天數(shù)以及對(duì)應(yīng)星期的方法
data(){
return {
dateList: [], // 日期list
month: 0, // 選中的月份
dayNum: 0 // 選中月的天數(shù)
}
}
created(){
this.montInfo(GetYearLastMonth())
// 當(dāng)前月的天數(shù)
const arr = GetYearLastMonth().split('-')
this.month = parseInt(arr[1])
this.dayNum = this.dayNumFn(parseInt(arr[0]), parseInt(arr[1]))
}
methods(){
// 月日以及對(duì)應(yīng)的星期
montInfo(res) {
/**
* 獲取一個(gè)月多少天，并獲取月初星期幾
*/
const daxier = ['一', '二', '三', '四', '五', '六', '日'];
const date = res ? new Date(res) : new Date()
const y = date.getFullYear()
const m = date.getMonth() + 1
var date2 = new Date(y, m, 0)
var rq = date2.getDate() // 日 本月最后一天
var xq = date2.getDay(); // 星期 本月第一天星期幾 new Date(0).getDay()
var rq2 = rq % 7
if (rq2 === 0) {
xq = rq2 + 1
} else {
if (rq2 > xq) xq += 7
xq = xq - rq2
}
var data = [];
for (var i = 1; i <= rq; i++) {
data.push({
'ri': i,
'xq': daxier[xq]
})
xq = (++xq === 7) ? 0 : xq
}
this.dateList = data
},
// 獲取選中月的天數(shù)
dayNumFn(year, month) {
return new Date(year, month, 0).getDate()
},
}根據(jù)查詢條件去切換表頭
{
label: '年月',
search: true,
hide: true,
searchPlaceholder: '請(qǐng)選擇年月',
searchClearable: false,
prop: 'yearMonth',
type: 'month',
// 日期組件格式化
format: 'yyyy-MM', // 展示值
// 單元格格式化
valueFormat: 'yyyy-MM', // value
searchDefault: GetYearLastMonth(),
pickerOptions: {
disabledDate: (time) => {
return time.getTime() > new Date(GetYearLastMonth()).getTime()
}
},
// 查詢條件月份切換的同事重新渲染表頭
change(value) {
// 當(dāng)前月的天數(shù)
$this.montInfo(value.value)
const arr = value.value.split('-')
$this.month = parseInt(arr[1])
$this.dayNum = $this.dayNumFn(parseInt(arr[0]), parseInt(arr[1]))
}
},因?yàn)椴煌脑路萑掌谟胁煌?，比?月只有28天而1月有31天。所以大于28的日期需要單獨(dú)處理一下

},element-ui的寫法相對(duì)簡單一些，因?yàn)榕渲庙?xiàng)沒辦法進(jìn)行遍歷渲染。
template里面的寫法
<el-table
:data="tableData"
>
<el-table-column
prop="month"
label="月份"
width="150"
header-align="center">
</el-table-column>
<!-- 這里使用遍歷的形式來進(jìn)行渲染 -->
<template v-for="(item,index) in dateList" >
<el-table-column :label="`${month}月${item.ri}日`" header-align="center" :key="'date' + index">
<el-table-column header-align="center" :label="`星期${item.xq}`" >
<el-table-column header-align="center" :prop="item.sw" label="上午" width="120" ></el-table-column>
<el-table-column header-align="center" :prop="item.xw" label="下午" width="120" ></el-table-column>
</el-table-column>
</el-table-column>
</template>
</el-table>data中還是聲明變量，methods中還是應(yīng)用和上面類似的方法
