看广告，绑定，分享，上报

HTML：

 <dio-share></dio-share>

<view v-show="douamry" style="position: absolute;font-size: 24rpx;top: 110rpx;left: 20rpx;align-self: flex-start;z-index: 999;">id:{{ douamry }}</view>

import {config} from "@/common/lib/app.js"
import { mapState, mapMutations } from 'vuex';
import { loggerShare, shareParam } from '../../common/tt.mini.js';

computed: {

...mapState(['userInfo'])
...mapState(['threadId','goodsMode','douamry']),
}

...mapMutations(['setState']) //放 methods 里

onShareAppMessage: function(shareOption) {
let shareparam = shareParam(shareOption);
loggerShare();
return shareparam;
}

video.ViodeAd.goodsId ='5f99221fff18333f42bd1f78';
new video.ViodeAd(self.reward,'11i5eb9h1gqc45c2i8')

放 onLoad 里

if(e.share){
            	if(config.userInfo.id){
            		this.$reports.report('/pages/kitchen_testIndex/kitchen_testIndex',JSON.stringify(e),false)
            	}
            	else{
            		uni.$once('login-temp-ok', function(){
            			self.$reports.report('/pages/kitchen_testIndex/kitchen_testIndex',JSON.stringify(e),false)
            		});
            	}
            }else{
            	this.$reports.report('/pages/kitchen_testIndex/kitchen_testIndex',JSON.stringify(e),true)
            }  

// 获取产品字典数据
this.$dio.dio('dicts/string', {
key: '_id',
value: config.dictKey //字典值
}).then(data => {
let value = data?.data?.data.value || {};
this.setState({ goodsMode: value }); // 产品字典里的数据
config.dynamicShareParam = value.dynamicShareParam; //分享文案
})

1.小程序默认去掉头部标题，在 path 字段下加如下代码

"style": {
"navigationStyle": "custom",
"enablePullDownRefresh":true, //下拉刷新
"onReachBottomDistance":50 //下拉刷新

}

onPullDownRefresh() {
console.log("正在下拉")
uni.stopPullDownRefresh(); //下拉之后停止下来
}

tabBar 例子

"tabBar": {
"color": "#080808",
"selectedColor": "#080808",
"borderStyle": "#4368c9",
"backgroundColor": "#4368c9",
"list": [{
"pagePath": "pages/answerIndex/answerIndex",
"iconPath": "/static/answerIndex/tabBar_home.png",
"selectedIconPath": "/static/answerIndex/tabBar_homeA.png"
,
"text": "首页"
},{
"pagePath": "pages/answerData/answerData",
"iconPath": "/static/answerIndex/tabBar_data.png",
"selectedIconPath": "/static/answerIndex/tabBar_dataA.png"
,
"text": "数据"
}, {
"pagePath": "pages/answerMy/answerMy",
"iconPath": "/static/answerIndex/tabBar_my.png",
"selectedIconPath": "/static/answerIndex/tabBar_myA.png"
,
"text": "我的"
}]
}

2.返回上一页

redirectTo

uni.navigateBack({
delta: 1
});

uni.navigateTo({
url: '../chicken_choosing/chicken_choosing'
});

3.提示弹窗

uni.showToast({
title: '请写下您的心情内容~',
duration: 2000,
icon:'none'
});

4.设置粘贴板内容

uni.setClipboardData({
data: ``
success: function () {
console.log('success');
}
});

4.页面传参数为数组，

将参数转为 JSON 字符串 JSON.stringify(对象)

接收页面转为数组对象 JSON.parse(字符串)

5.得出今日日期

(1).

let date = new Date();
let year = date.getFullYear();
let month = date.getMonth() + 1 > 9 ? date.getMonth() + 1 : "0" + parseInt(date.getMonth() + 1);
let day = date.getDate();
this.date = year + "." + month + "." + day;

(2)js 获取当前日期方法（YYYY-MM-DD 格式）

var time = myDate.toLocaleDateString().split('/').join('-');将 1970/08/08 转化成 1970-08-08（iOS 不兼容）

获取天数：(new Date("2021-01-22").getTime()-new Date("2021-01-20").getTime())/ 1000 / 60 / 60 /24（iOS 兼容）

6.比较两个日期之间相距多少天

DateDiff(sDate1, sDate2){ //sDate1 和 sDate2 是 2002-12-18 格式
let iDays;
let sDate1=new Date(sDate1);
let sDate2=new Date(sDate2);
let iDays = parseInt(Math.abs(sDate1 - sDate2) / 1000 / 60 / 60 /24); //把相差的毫秒数转换为天数
return iDays;
}

6.登录

 tryLogin(){
                if(this.userInfo?.nickName){
                    return;
                }
                // 获取用户信息
                uni.getUserInfo({
                    success(e) {
                        self.setState({userInfo:{...e.userInfo,...self.userInfo}})
                        uni.setStorageSync('userInfo',self.userInfo)
                    },
                    fail(error) {
                        console.log(error);
                        uni.openSetting({
                          success(res) {
                            uni.getUserInfo({
                                success(e) {
                                    console.log(e);
                                    self.setState({userInfo:{...e.userInfo,...self.userInfo}})
                                    uni.setStorageSync('userInfo',self.userInfo)
                                }
                            })
                          }
                        });
                    }
                })
                
            }

7.清除缓存，苹果手机失效

if(e.query.clearstorage){
// uni.clearStorage();
uni.clearStorageSync()
uni.showToast({
title:'清除本地缓存成功'
})}

8.用 js 取 1-100 的随机数 https://www.cnblogs.com/xyn0909/p/8574926.html

function sum (m,n){
　　var num = Math.floor(Math.random()*(m - n) + n);
　　alert(num)
}
sum(1,100)；

8.获取节点元素高度

let query = uni.createSelectorQuery();

query.select('#id').boundingClientRect();

query.exec(function (res) {
console.log("当前元素的 res：",res) console.log(res[0].width, res[0].height,res[0].top);
});

9.获取数字数组前 n 个数字相加的和？

getListValue(list, max) {
var total = 0;
for (let i = 0; i < max; i++) {
total = total + list[i];
}
return total;
}

10.获取数组中 n 个不重复元素组成的新数组？

getRandomArrayElements(arr, count) {
var shuffled = arr.slice(0),
i = arr.length,
min = i - count,
temp, index;
while (i-- > min) {
index = Math.floor((i + 1) * Math.random());
temp = shuffled[index];
shuffled[index] = shuffled[i];
shuffled[i] = temp;
}
return shuffled.slice(min);
}
