一、背景
基于element日期选择组件,自行封装了一个组件。
以下是达到的效果:
1.选择年,日期选择组件默认填充是:当时的年;
2.选择月,日期选择组件默认填充的是:当时的年月;
3.选择日,日期选择组件默认填充的是:当时的年月日;
备注:
1.自行封装的组件,涉及到把所选的值暴露给其它“单页面组件”,通过vue3的defineExpose(),vue2需要修改一下;
2.自行封装的组件,涉及到传参,根据接口要求,传参了属性dataType;
3.自行封装的组件,涉及到判断条件,所选不能超过30天。
二、实现效果
三、代码
自行封装的组件,vue3 setup写法:
<script setup>
import { nextTick, onMounted, reactive, ref } from "vue";
import { getDatePiker } from "@/utils/cabinData";
import {timeLimits} from "@/utils"
const timeRange = 1 * 24 * 60 * 60 * 1000; // 1天时间戳
const timeToTimestamp = (time) => {
let timestamp = Date.parse(new Date(time).toString());
return timestamp;
};
export const timeLimits=(times,message,intervalTime=7)=>{
const minTime = timeToTimestamp(times[0]);
const maxTime = timeToTimestamp(times[1]);
const isOver7 = maxTime - minTime > timeRange * intervalTime;
if (isOver7) {
ElMessage({
type: "warning",
message: message===undefined?`历史记录查询时间不能超过7天`:message,
});
return false;
}else{
return true;
}
}
const timeTypeList = reactive([
{
name: "年",
dateType: "2",
type: "year",
valueFormat: "YYYY",
getDatePikerformat: "yyyy",
range: false,
},
{
name: "月",
dateType: "1",
type: "month",
valueFormat: "YYYY-MM",
getDatePikerformat: "yyyy-MM",
range: false,
},
{
name: "自定义",
dateType: "3",
type: "daterange",
valueFormat: "YYYY-MM-DD",
range: true,
},
]);
const Selected = ref(2);
const data = reactive({
time: null,
});
const changeSelected = (_index) => {
Selected.value = _index;
if (timeTypeList[_index].range) {
nextTick(() => {
data.time = getDatePiker(30);
});
} else {
data.time = getDatePiker(30, timeTypeList[_index].getDatePikerformat)[1];
// console.log(timeTypeList[_index].valueFormat);
}
};
onMounted(() => {
data.time = getDatePiker(30);
});
const getTimeParams = () => {
if (!timeTypeList[Selected.value].range) {
return {
dateType: timeTypeList[Selected.value].dateType,
dateTime: data.time,
};
} else {
if(timeLimits(data.time,'历史记录查询或者导出不能超过30天',30)){
return false
}else{
return {
dateType: timeTypeList[Selected.value].dateType,
startTime: data.time[0],
endTime: data.time[1],
};
}
}
};
defineExpose({
getTimeParams,
});
</script>
<template>
<div class="time_change">
<div
class="time_type"
v-for="(item, index) in timeTypeList"
:key="index"
:class="Selected === index ? 'time_type_selected' : ''"
@click="changeSelected(index)"
>
{{ item.name }}
</div>
<el-form :model="data" class="search-box2">

:unlink-panels="true"
:clearable="false"
/>
</el-form-item>
</el-form>
</div>
</template>
<style lang="less" scoped>
.time_change {
width: 100%;
height: 100%;
display: flex;
justify-content: space-between;

.time_type {

}
.time_type_selected {
background: #4279ca;
color: #ffffff;
}
.search-box2 {
width: 423px;
height: 36px;
line-height: 36px;
:deep(.el-form-item) {
.el-form-item__label {
padding-left: 0.57292vw;
background-color: #dae5f2 !important;
color: #4279ca;
font-size: calc(100vw * 16 / 1920);
height: 2.1875vw;
text-align: center;
line-height: 2.1875vw;
justify-content: flex-start;
}
.el-date-editor .el-range-input{
font-size: calc(100vw * 18 / 1920);
}
.el-input__inner{
font-size: calc(100vw * 18 / 1920);
}
}
.el-form-item {
width: 100%;
height: 100%;
box-sizing: border-box;
margin: 0;
border: none;
line-height: inherit;
background: #f0f5fa;
border-radius: 4px 4px 4px 4px;
border: 1px solid #ffffff;
:deep(.el-form-item__label) {
height: 100%;
border-radius: 4px;
line-height: inherit;
}
:deep(.el-form-item__content) {
flex: 1;
.el-input {
height: 100%;
}
.el-input__wrapper {
box-shadow: none;
background: none;
height: 100%;
}
}
}
}
}
</style>
四、其它
1.组件默认填充时间,默认填充最近30天;
eg:
getDatePiker(30);
/**
* 时间选择器默认选中,最近多少天
*/
export const getDatePiker = (dates,dateType='yyyy-MM-dd') => {
let valueTwoTimer = []
let newData = new Date();
let nowMonth = frontOneHour(newData, dateType);
const front12Hour = new Date(newData - 1000 * 60 * 60 * 24 * (dates-1));;
let beforeMonth = frontOneHour(front12Hour, dateType);
valueTwoTimer.push(beforeMonth);
valueTwoTimer.push(nowMonth);
return valueTwoTimer
};
2.不能超过30天数,当不传参的时候默认不超过7天;
eg:
timeLimits(data.time, "历史记录查询或者导出不能超过30天", 30)
//
const timeRange = 1 * 24 * 60 * 60 * 1000; // 1天时间戳
const timeToTimestamp = (time) => {
let timestamp = Date.parse(new Date(time).toString());
return timestamp;
};
export const timeLimits=(times,message,intervalTime=7)=>{
const minTime = timeToTimestamp(times[0]);
const maxTime = timeToTimestamp(times[1]);
//判断是否超过7天,或者30天。接收传参intervalTime
const isOver7 = maxTime - minTime > timeRange * intervalTime;
if (isOver7) {
//超过7天,进行显示提示信息。并打断,给调用的语句返回一个false
//外层调用根据返回的“false”,进行打断处理,详见如下写在后面。
ElMessage({
type: "warning",
message: message===undefined?`历史记录查询时间不能超过7天`:message,
});
return false;
}else{
return true;
}
}
2.写在最后
外层调用timeLimits()
//暴露此方法
//如果超过30天,返回false;否则返回开始时间和结束时间,以及dateType(接口参数)
const getTimeParams = () => {
if (!timeTypeList[Selected.value].range) {
return {
dateType: timeTypeList[Selected.value].dateType,
dateTime: data.time,
};
} else {
if (!timeLimits(data.time, "历史记录查询或者导出不能超过30天", 30)) {
return false;
} else {
return {
dateType: timeTypeList[Selected.value].dateType,
startTime: data.time[0],
endTime: data.time[1],
};
}
}
};
defineExpose({
getTimeParams,
});
五、年月日分别解释
1.选择年,日期选择组件默认填充是:当时的年;
2.选择月,日期选择组件默认填充的是:当时的年月;
3.选择日,日期选择组件默认填充的是:当时的年月日;
默认填充最近30天。
