2、引入组件库

网址:https://www.uviewui.com/

3、问题如下

(1)使用SwipeAction 滑动单元格后,在滑动单元格上无法上下滑动

解决方法:自己写,代码如下

<template>
    <view class="main">
        <view
        v-for="(item, index) in infoList"
        :key="index"
        :data-index="index"
        class="order-item"
        @touchstart="drawStart"
        @touchmove="drawMove"
        @touchend="drawEnd"
        :style="'right:'+item.right+'px'">
            <view class="content">
                我打碎了夕阳,也揉碎了月光,拉着李白大醉一场,撒下九州的霜{{item.label}}
            </view>
            <view class="edit">编辑</view>
            <view class="remove">删除</view>
        </view>
        <u-popup :show="showKong">
            <view>
            </view>
        </u-popup>
    </view>
</template>

<script>
    export default {
        components: {

        },
        props: {

        },
        data() {
            return {
                //左滑默认宽度

                startX: 0,

                        label: '我打碎了夕阳,也揉碎了月光,拉着李白大醉一场,撒下九州的霜',
                        right: 0
                    },

                    {

                        right: 0
                    },
                    {
                        label: '我打碎了夕阳,借了一碗清汤,想等一束月光,可倒影全是你的模样',

                        right: 0
                    },

                    this.$set(this.infoList[index],'right',0);
                }
                var touch = e.touches[0];
                var item = this.infoList[e.currentTarget.dataset.index];
                var disX = this.startX - touch.clientX;
                if (disX >= 20) {
                        if (disX > this.delBtnWidth) {
                        disX = this.delBtnWidth;
                        }
                        this.$set(this.infoList[e.currentTarget.dataset.index],'right',disX);
                } else {
                    this.$set(this.infoList[e.currentTarget.dataset.index],'right',0);
                }
            },
            //触摸滑动结束
            drawEnd(e) {
                var item = this.infoList[e.currentTarget.dataset.index];
                if (item.right >= this.delBtnWidth / 2) {
                    this.$set(this.infoList[e.currentTarget.dataset.index],'right',this.delBtnWidth);
                } else {

                }
                this.showKong = true;
                this.showKong = false;
            }
        }
    }
</script>

<style lang="scss">
.main{
    width: 100%;
    height: auto;
    margin: 10px auto;
    overflow: hidden;
    .order-item {

        padding: 48rpx;
        border-bottom: 1px solid #ddd;

</style>

(2)列表数据改变后列表数据不变

解决方法:网上的方法试了,也不好用,就加一个空的弹出层,数据改变后显示隐藏

<u-popup :show="showKong">
    <view>
    </view>
</u-popup>
this.showKong = true;
this.showKong = false;

(3)需求:筛选1个月以下,3个月以下,1年以内,1-3年,3-5年,需要传给后端时间段,我需要获取当前时间,1个月前的时间,3个月前的时间,1年前的时间,3年前的时间,5年前的时间

没有使用moment.js,不知道在这里可不可用,写的第一个方法web端好用,app报错,最终使用的方法如下:

const getFormatDate = (dateInfo) => { // 获取时间,格式YYYY-MM-DD
    if (!dateInfo) {
        return
    }
    let date = dateInfo;
    let seperator1 = "-";
    let year = date.getFullYear();
    let month = date.getMonth() + 1;
    let strDate = date.getDate();
    if (month >= 1 && month <= 9) {
        month = "0" + month;
    }
    if (strDate >= 0 && strDate <= 9) {
        strDate = "0" + strDate;
    }
    let currentdate = year + seperator1 + month + seperator1 + strDate;
    return currentdate;
}
/* 获取之前的日期 1个月前传2一年前传13*/
const getFDate = (num,type) => {
     const date = getFormatDate(new Date()).split('-')
     let yy0=parseInt(date[0]);
     let mm0=parseInt(date[1]);
     let dd0=parseInt(date[2]);
     let pdStr = getFormatDate(new Date(yy0,mm0-num,dd0-type));
     return pdStr; // 可针对需要的格式进行优化。
 }    

/* 时间段定义 */
ageSearchOption: [{
        name: '全部',
        value: '',
        maxBirthday: '',
        minBirthday: ''
        }, {
        name: '1个月以下',
        value: '1',
        maxBirthday: common.getFDate(1,0),
        minBirthday: common.getFDate(2,1)
        }, {
        name: '3个月以下',
        value: '2',
        maxBirthday: common.getFDate(1,0),
        minBirthday: common.getFDate(4,1)
        }, {
        name: '1岁以下',
        value: '3',
        maxBirthday: common.getFDate(1,0),
        minBirthday: common.getFDate(13,1)
        },{
        name: '1-3岁',
        value: '4',
        maxBirthday: common.getFDate(13,0),
        minBirthday: common.getFDate(37,1)
        }, {
        name: '3-5岁',
        value: '5',
        maxBirthday: common.getFDate(37,0),
        minBirthday: common.getFDate(61,1)
    }]

(4)获取当前日期后面几天的日期

const getNextDay = (cdate,daynum) => { // cdate:日期,daynum:几天
    var date = new Date(cdate);
    var base = Date.parse(date); // 转换为时间戳
    var year = date.getFullYear(); //获取当前年份
    var mon = date.getMonth() + 1; //获取当前月份
    var day = date.getDate(); //获取当前日
    var oneDay = 24 * 3600 *1000

    var daytimeArr = []
    var now = new Date(base += oneDay*daynum);
    var myear = now.getFullYear();
    var month = now.getMonth() + 1;
    var mday = now.getDate()
    daytimeArr.push([myear, month >=10 ?month :'0'+ month, mday>=10?mday:'0'+mday].join('-'))
    return daytimeArr[0]

}

(5)根据出生日期判断年龄

const getAge = (strBirthday) => { // 根据出生日期计算年龄
    //strBirthday传入格式 2020-04-15
    if (!strBirthday) {
        return
    }
    var returnAge;
    var strBirthdayArr = strBirthday.split('-');
    var birthYear = strBirthdayArr[0];
    var birthMonth = strBirthdayArr[1];
    var birthDay = strBirthdayArr[2].substr(0,2);
    //获取当前日期
    var d = new Date();
    var nowYear = d.getFullYear();
    var nowMonth = d.getMonth() + 1;
    var nowDay = d.getDate();
    if (nowYear == birthYear) {
        // returnAge = 0; //同年 则为0岁
        if (nowMonth==birthMonth) {
            returnAge = nowDay-birthDay + '天'
        } else {
            returnAge = nowMonth-birthMonth + '个月'
        }
    } else {
        var ageDiff = nowYear - birthYear; //年之差
        if (ageDiff > 0) {
            if (nowMonth == birthMonth) {
                var dayDiff = nowDay - birthDay; //日之差
                if (dayDiff < 0) {
                    returnAge = ageDiff - 1 + '岁';
                } else {
                    returnAge = ageDiff + '岁';
                }
            } else if (nowMonth > birthMonth) {
                returnAge = ageDiff + '岁' + (nowMonth-birthMonth) + '个月'
            } else  if (nowMonth < birthMonth){
                returnAge = ageDiff-1 + '岁' +(12 - birthMonth + nowMonth) + '个月'
                if(ageDiff-1==0){
                    returnAge = (12 - birthMonth + nowMonth) + '个月'
                }
            }
        } else {
            returnAge = -1; //返回-1 表示出生日期输入错误 晚于今天
        }
    }
    return returnAge; //返回周岁年龄
}

(6)保存sku图片功能

链接:https://www.cnblogs.com/boreguo/p/16327447.html

(7)app扫码功能

uni.scanCode方法

(8)使用icon图标操作过于频繁偶现undefined

解决方法:这个我这边正常操作没有复现这个问题,是测试那边偶发的,最后把icon图标改成image图了

(9)token刷新与网络中断提示,这个把请求封装了一下request.js

//const baseUrl = 'https://cpkx.bjzkkp.com:7110/'; // 正式
const baseUrl = 'http://cpkx.bjzkkp.com:7010/'; // 测试

// 不带token请求
const httpRequest = (opts, data) => {

(11)全局样式配置

在pages.json中配置globalStyle
a.横屏配置
"pageOrientation": "landscape", //横屏配置,全局屏幕旋转设置(仅 APP/微信/QQ小程序),支持 auto / portrait / landscape
b.屏幕适配
"rpxCalcMaxDeviceWidth": 960, // rpx 计算所支持的最大设备宽度,单位 px,默认值为 960
"rpxCalcBaseDeviceWidth": 375, // rpx 计算使用的基准设备宽度,设备实际宽度超出 rpx 计算所支持的最大设备宽度时将按基准宽度计算,单位 px,默认值为 375
"rpxCalcIncludeWidth": 750 // rpx 计算特殊处理的值,始终按实际的设备宽度计算,单位 rpx,默认值为 750

(12)刷新页面

主要涉及父子组件之间传参,保存成功后像父组件发送刷新请求。

(13)app版本检查更新功能,获取服务器版本,获取本地版本,判断版本号是否相同,相同无更新,不同就根据后端返回的apk地址去更新
