Avue和Element-UI動態三級表頭的實現
需求場景： 業務方希望有表格可以體現員工的考勤信息，要具體到上午下午，統計司機上下班打卡所產生的數據。產品提出想做成三級表頭根據頁面查詢條件的年月去動態生成表格的表頭。三級分別是月份日期，對應的星期，以及每天的上午以及下午。
效果如下：
Avue配置方式
通過對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月天數以及對應星期的方法
data(){
return {
dateList: [], // 日期list
month: 0, // 選中的月份
dayNum: 0 // 選中月的天數
}
}
created(){
this.montInfo(GetYearLastMonth())
// 當前月的天數
const arr = GetYearLastMonth().split('-')
this.month = parseInt(arr[1])
this.dayNum = this.dayNumFn(parseInt(arr[0]), parseInt(arr[1]))
}
methods(){
// 月日以及對應的星期
montInfo(res) {
/**
* 獲取一個月多少天，並獲取月初星期幾
*/
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 本月最後一天
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
dayNumFn(year, month) {
return new Date(year, month, 0).getDate()
},
}
根據查詢條件去切換表頭
{
label: '年月',
search: true,
hide: true,
searchPlaceholder: '請選擇年月',
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) {
// 當前月的天數
$this.montInfo(value.value)
const arr = value.value.split('-')
$this.month = parseInt(arr[1])
$this.dayNum = $this.dayNumFn(parseInt(arr[0]), parseInt(arr[1]))
}
},
因為不同的月份日期有不同，比如2月隻有28天而1月有31天。所以大於28的日期需要單獨處理一下
{
label: $this.dayNum > 28 ? `${$this.month}月${$this.dateList[28].ri}日` : '',
headerAlign: 'center',
hide: $this.dayNum < 28,
children: [
{
label: $this.dayNum > 28 ? `星期${$this.dateList[28].xq}` : '',
headerAlign: 'center',
children: [
{
label: '上午',
prop: 'twentyNineAmAttendance',
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.twentyNineAmAttendance) {
satData = item.name
}

return satData

console.log(e)

})
return satData
} catch (e) {

}
}
}
]
}
]
},
{

return satData

}
]
},
{

headerAlign: 'center',

children: [

Element-UI三級表頭動態寫法
element-ui的寫法相對簡單一些，因為配置項沒辦法進行遍歷渲染。
template裡面的寫法
<el-table
:data="tableData"
style="width: 100%" >
<el-table-column
prop="month"
label="月份"
width="150"
header-align="center">
</el-table-column>
<!-- 這裡使用遍歷的形式來進行渲染 -->
<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中還是應用和上面類似的方法
data(){
return {
dateList: [], // 日期list
month: 0, // 選中的月份
dayNum: 0, // 選中月的天數
}
}
created() {
this.montInfo(GetYearLastMonth())
// 當前月的天數
const arr = GetYearLastMonth().split('-')
this.month = parseInt(arr[1])
this.dayNum = this.dayNumFn(parseInt(arr[0]), parseInt(arr[1]))
},
methods: {
// 月日以及對應的星期
montInfo(res) {
/**
* 獲取一個月多少天，並獲取月初星期幾
*/
const daxier = ['一', '二', '三', '四', '五', '六', '日'];
// 這裡是每個上午下午展示為不同的變量
const amArr = ['oneAmAttendance', 'twoAmAttendance', 'threeAmAttendance', 'fourAmAttendance', 'fiveAmAttendance', 'sixAmAttendance', 'sevenAmAttendance', 'eightAmAttendance', 'nineAmAttendance', 'tenAmAttendance', 'elevenAmAttendance', 'twelveAmAttendance', 'thirteenAmAttendance', 'fourteenAmAttendance', 'fifteenAmAttendance', 'oneAmAttendance', 'twoAmAttendance', 'threeAmAttendance', 'fourAmAttendance', 'fiveAmAttendance', 'sixAmAttendance', 'sevenAmAttendance', 'eightAmAttendance', 'nineAmAttendance', 'tenAmAttendance', 'elevenAmAttendance', 'twelveAmAttendance', 'thirteenAmAttendance', 'fourteenAmAttendance', 'fifteenAmAttendance', 'sixteenAmAttendance', 'seventeenAmAttendance', 'eighteenAmAttendance', 'nineteenAmAttendance', 'twentyAmAttendance', 'twentyOneAmAttendance', 'twentyTwoAmAttendance', 'twentyThreeAmAttendance', 'twentyFourAmAttendance', 'twentyFiveAmAttendance', 'twentySixAmAttendance', 'twentySevenAmAttendance', 'twentyEightAmAttendance', 'twentyNineAmAttendance', 'thirtyAmAttendance', 'thirtyOneAmAttendance']
const pmArr = [
'onePmAttendance', 'twoPmAttendance', 'threePmAttendance', 'fourPmAttendance', 'fivePmAttendance', 'sixPmAttendance', 'sevenPmAttendance', 'eightPmAttendance', 'ninePmAttendance', 'tenPmAttendance', 'elevenPmAttendance', 'twelvePmAttendance', 'thirteenPmAttendance', 'fourteenPmAttendance', 'fifteenPmAttendance', 'onePmAttendance', 'twoPmAttendance', 'threePmAttendance', 'fourPmAttendance', 'fivePmAttendance', 'sixPmAttendance', 'sevenPmAttendance', 'eightPmAttendance', 'ninePmAttendance', 'tenPmAttendance', 'elevenPmAttendance', 'twelvePmAttendance', 'thirteenPmAttendance', 'fourteenPmAttendance', 'fifteenPmAttendance', 'sixteenPmAttendance', 'seventeenPmAttendance', 'eighteenPmAttendance', 'nineteenPmAttendance', 'twentyPmAttendance', 'twentyOnePmAttendance', 'twentyTwoPmAttendance', 'twentyThreePmAttendance', 'twentyFourPmAttendance', 'twentyFivePmAttendance', 'twentySixPmAttendance', 'twentySevenPmAttendance', 'twentyEightPmAttendance', 'twentyNinePmAttendance', 'thirtyPmAttendance', 'thirtyOnePmAttendance'
]
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 本月最後一天
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
}
data.map((item, index) => {
item.sw = amArr[index]
item.xw = pmArr[index]
})
this.dateList = data
},
// 獲取選中月的天數
dayNumFn(year, month) {
console.log(new Date(year, month, 0).getDate())
return new Date(year, month, 0).getDate()
}
}
