前言

排名不分先后,按自己的習(xí)慣來的。

總結(jié)經(jīng)驗,不喜勿噴哦~

一、tab切換

<view class=" {{currentTab==0 ? 'select' : ''}}" data-current="0" bindtap="swichNav"> tab1</view>
<view class=" {{currentTab==1 ? 'select' : ''}}" data-current="1" bindtap="swichNav"> tab2</view>

Page({
data:{
 // tab切換 
 currentTab: 0,
},
swichNav: function (e) {
 var that = this;
 if (this.data.currentTab === e.target.dataset.current) {
 return false;
 } else {
 that.setData({
 currentTab: e.target.dataset.current
 })
 }
 },

})

二、swiper切換

<view>
  <text class=" {{currentTab==0 ? 'select' : ''}}" data-current="0" bindtap="swichNav">tab1</text>
  <text class=" {{currentTab==1 ? 'select' : ''}}" data-current="1" bindtap="swichNav">tab2 </text>
  <text class=" {{currentTab==2 ? 'select' : ''}}" data-current="2" bindtap="swichNav">tab3 </text>
  </view>
 <swiper current="{{currentTab}}" bindchange="bindChange" class='swp' >
 <swiper-item>頁面1</swiper-item>
 <swiper-item>頁面2</swiper-item>
 <swiper-item>頁面3</swiper-item>
 </swiper>

Page({
data:{
 currentTab: 0,
 aheight: ''
},
// 滑動切換
 bindChange: function (e) {
 var that = this;
 that.setData({
 currentTab: e.detail.current
 });
 },
 //點擊tab切換
 swichNav: function (e) {
 var that = this;
 if (this.data.currentTab === e.target.dataset.current) {
 return false;
 } else {
 that.setData({
 currentTab: e.target.dataset.current
 })
 }
 },
 // swiper 自適應(yīng)高度
 onLoad: function (options) {
 var that = this
 wx.getSystemInfo({
 success: function (res) {
 that.setData({
  aheight: res.screenHeight
 });
 }
 })
 },
})

三、圖片上傳

 <view class="ovf img_box">
  <block wx:for="{{img_arr}}" wx:key="{{item.id}}" bindtap="del">
  <view class='logoinfo' data-index="{{index}}">
   <view class="del">
   <image src="http://192.168.2.61/wx_ry/del.png" mode="widthFix" bindtap="deleteImage"></image>
   </view>
   <image src='{{item}}' mode="widthFix"></image>
  </view>
  </block>
  <view class="upload">
   <image src="http://192.168.2.61/wx_ry/add.png" mode="widthFix" bindtap="upimg"></image>
  </view>
 </view>

.upload { width: 20%; float: left; margin-top:33rpx ; }
.upload image{ width: 100%; }
.logoinfo{ width: 20%; float: left; margin-right:2% ; }
.del{ width: 20%; float: right; }
.del image{ width: 100%; }
.logoinfo image{ width: 100%; }

page({
data:{
 img_arr: []
},
 // 圖片上傳
 upimg: function () {
 var that = this;
 if (this.data.img_arr.length < 3) {
 wx.chooseImage({
 sizeType: ['original', 'compressed'],
 success: function (res) {
  that.setData({
  img_arr: that.data.img_arr.concat(res.tempFilePaths),
  })

 }
 })
 } else {
 wx.showToast({
 title: '最多上傳三張圖片',
 icon: 'loading',
 duration: 3000
 });
 }
 },
 // 刪除圖片
 deleteImage: function (e) {
 var that = this;
 var index = e.currentTarget.dataset.index; //獲取當(dāng)前長按圖片下標
 console.log(that.data.img_arr)
 wx.showModal({
 title: '提示',
 content: '確定要刪除此圖片嗎?',
 success: function (res) {
 if (res.confirm) {
  console.log('點擊確定了');
  that.data.img_arr.splice(index, 1);
 } else if (res.cancel) {
  console.log('點擊取消了');
  return false;
 }
 that.setData({
  img_arr: that.data.img_arr
 });
 }
 })
 },
 // 上傳
 upload: function () {
 var that = this
 for (var i = 0; i < this.data.img_arr.length; i++) {
 wx.uploadFile({
 url: 'https:***/submit',
 filePath: that.data.img_arr[i],
 name: 'content',
 formData: adds,
 success: function (res) {
  console.log(res)
  if (res) {
  wx.showToast({
  title: '已提交發(fā)布!',
  duration: 3000
  });
  }
 }
 })
 }
 this.setData({
 formdata: ''
 })
 },
 // 提交
 formSubmit: function (e) {
 console.log('form發(fā)生了submit事件,攜帶數(shù)據(jù)為:', e.detail.value)
 }
})

四、scroll-view滾動頁

 <scroll-view class="scroll-view_H " scroll-x="true" bindscroll="scroll">
 <view class="fxjx_b1" >
 <view class="listb">1</view>
 </view>
 <view class="fxjx_b1" >
 <view class="listb">2</view>
 </view>
 </scroll-view>

.scroll-view_H{ white-space: nowrap; height: 600rpx; }
.listb{ padding: 25rpx; white-space: normal; }

五、授權(quán)登錄

app.js

//app.js
App({
 globalData: {
 userInfo: null,
 unionid:null,
 token:''
 },
 onLaunch: function () {
 /* 已授權(quán)之后,自動獲取用戶信息 */
 // 判斷是否授權(quán)
 wx.getSetting({
 success: (res) => { //箭頭函數(shù)為了處理this的指向問題 
 if (res.authSetting["scope.userInfo"]) {
 console.log("已授權(quán)");
 // 獲取用戶信息
 wx.getUserInfo({
  success: (res) => { //箭頭函數(shù)為了處理this的指向問題
  // this.globalData.isok=true
  this.globalData.token='ok'
  var that =this
  console.log(res.userInfo); //用戶信息結(jié)果
  wx.getStorage({
  key: 'unionid',
  success(res) {
  that.globalData.unionid=res.data
  }
  })
  this.globalData.userInfo = res.userInfo;
  if (this.userInfoReadyCallback) { //當(dāng)index.js獲取到了globalData就不需要回調(diào)函數(shù)了,所以回調(diào)函數(shù)需要做做一個判斷,如果app.js中有和這個回調(diào)函數(shù),那么就對這個函數(shù)進行調(diào)用,并將請求到的結(jié)果傳到index.js中
  this.userInfoReadyCallback(res.userInfo);
  }
  }
 })
 }
 else{
 console.log("未授權(quán)");
 wx.removeStorage({
  key: 'unionid'
 })
 }
 }
 })
 }
})

wxml

 <button open-type="getUserInfo" lang="zh_CN" bindgetuserinfo="onGotUserInfo" class="btn" data-url='../yzzs/yzzs'>
  防疫針助手
 </button>

index.js

// pages/index/index.js
const app = getApp()
Page({
 data: {
 token:''
 },
 onGotUserInfo: function (e) {
 var that = this
 if (this.data.token != 'ok' && app.globalData.token != 'ok') {
 wx.getSetting({
 success: (res) => { //箭頭函數(shù)為了處理this的指向問題 
  if (res.authSetting["scope.userInfo"]) {
  wx.login({
  success: function (data) {
  console.log('獲取登錄 Code:' + data.code)
  var postData = {
   code: data.code
  };
  wx.request({
   url: 'https://m.renyiwenzhen.com/rymember.php?mod=xcxlogin&code=' + postData.code + '&nickname=' + e.detail.userInfo.nickName,
   data: {},
   header: {
   'content-type': 'application/json'
   },
   success: function (res) {
   console.log(res.data);
   that.data.token='ok';
   wx.setStorage({
   key: "unionid",
   data: res.data.unionid
   })
   wx.navigateTo({
   url: e.target.dataset.url
   })
   },
   fail: function () {
   console.log('1');
   }
  })
  },
  fail: function () {
  console.log('登錄獲取Code失?。?);
  }
  })
  }
 }
 })
 } else{
 wx.navigateTo({
 url: e.target.dataset.url
 })
 }
 }
})

六、發(fā)送請求

 wx.request({
  url: 'https://m.renyiwenzhen.com/xcx_ajax.php?action=babylist', //僅為示例,并非真實的接口地址
  method: 'post',
  data: {
  unionid: uni
  },
  header: {
  'content-type': 'application/x-www-form-urlencoded' // 默認值
  },
  success(res) {
  // console.log(uni)
  console.log(res.data)
  that.setData({
  list: res.data.bblist
  })
  }
  })

七、標題欄及底部欄

全局標題欄

 "window": {
 "backgroundTextStyle": "light",
 "navigationBarBackgroundColor": "#3EC8C8",
 "navigationBarTitleText": "乳孕呵護",
 "navigationBarTextStyle": "white"
 }

局部標題欄

{
 "usingComponents": {},
 "navigationBarBackgroundColor": "#fff",
 "navigationBarTextStyle": "black",
 "navigationBarTitleText": "附近醫(yī)院"
}

全局底部欄

"tabBar": {
 "color": "#e4e4e4",
 "selectedColor": "#333",
 "list": [
 {
 "pagePath": "pages/index/index",
 "text": "發(fā)現(xiàn)",
 "iconPath": "./images/find.png",
 "selectedIconPath": "./images/finded.png"
 },
 {
 "pagePath": "pages/his/his",
 "text": "醫(yī)院",
 "iconPath": "./images/his.png",
 "selectedIconPath": "./images/hised.png"
 },
 {
 "pagePath": "pages/stu/stu",
 "text": "經(jīng)驗",
 "iconPath": "./images/stu.png",
 "selectedIconPath": "./images/stued.png"
 },
 {
 "pagePath": "pages/my/my",
 "text": "我的",
 "iconPath": "./images/my.png",
 "selectedIconPath": "./images/myed.png"
 }
 ]
 }

八、navigator

1、wxml

<navigator url="/pages/hishome/hishome" open-type="navigate" hover-class="none"> 
底部欄沒有的路由
</navigator>
<navigator open-type="switchTab" url="/pages/his/his" hover-class="none">
底部欄有的路由
</navigator>

2、js

 go: function (e) {
 wx.navigateTo({
 url: '../eatxq/eatxq?id=' + e.currentTarget.dataset.id + "&name=" + e.currentTarget.dataset.name
 })
 }

九、加載條

<loading hidden="{{onff}}">加載中</loading>
<view>頁面</view>

加載完成true

wx.request({
  url: 'https://m.renyiwenzhen.com/xcx_ajax.php?action=caneatsearch', 
  method: 'post',
  header: {
  'content-type': 'application/x-www-form-urlencoded' // 默認值
  },
  data: {
  search: options.search
  },
  success(res) {
  that.setData({
  list: res.data.fllist,
  onff: true
  })
  }
  })

十、富文本處理

 <view class="txt">
 <rich-text nodes="{{msg}}" ></rich-text>
 </view>

利用正則修改收到的數(shù)據(jù)

 wx.request({
 url: 'https://m.renyiwenzhen.com/xcx_ajax.php?action=cjdetail', 
 method: 'post',
 data: {
 id: options.id
 },
 header: {
 'content-type': 'application/x-www-form-urlencoded' // 默認值
 },
 success(res) {
 that.setData({
  msg: res.data.cjmag.cjxq.replace(/\<p>/g, "<p style='line-height: 24px; font-size:15px;text-align: justify;margin:15px 0;'>")
 })
 }
 })

十一、filter過濾數(shù)據(jù)

1、在根目錄下的utils文件夾里創(chuàng)建一個名為filter.wxs文件 2、寫入自己要定義的條件

var xb=function (v) {
 var xingb=''
 if(v==1){
 xingb="男寶寶"
 }
 else{
 xingb="女寶寶"
 }
 return xingb
}
module.exports = {
 xb:xb
}

3、在頁面中引入使用

<wxs src="../../utils/filter.wxs" module="filter" />
<view><text>{{filter.xb(isxb)}}</text></view>

十二、檢測版本更新

app.js

 onLaunch: function () {
 if (wx.canIUse('getUpdateManager')) {
 const updateManager = wx.getUpdateManager()
 updateManager.onCheckForUpdate(function (res) {
 // 請求完新版本信息的回調(diào)
 if (res.hasUpdate) {
  updateManager.onUpdateReady(function () {
  wx.showModal({
  title: '更新提示',
  content: '新版本已經(jīng)準備好,是否重啟應(yīng)用?',
  success: function (res) {
  // res: {errMsg: “showModal: ok”, cancel: false, confirm: true}
  if (res.confirm) {
   // 新的版本已經(jīng)下載好,調(diào)用 applyUpdate 應(yīng)用新版本并重啟
   updateManager.applyUpdate()
  }
  }
  })
  })
  updateManager.onUpdateFailed(function () {
  // 新的版本下載失敗
  wx.showModal({
  title: '已經(jīng)有新版本了喲~',
  content: '新版本已經(jīng)上線啦,請您刪除當(dāng)前小程序,重新搜索打開喲'
  })
  })
 }
 })
 }
}

十三、點擊tab跳轉(zhuǎn)對應(yīng)的的項目頁面

我們經(jīng)常會遇到這種需求:

點擊對應(yīng)的的tab,這里比如說是A頁。

微信小程序?qū)嵱么a段(收藏版)

跳轉(zhuǎn)到對應(yīng)項目的頁面,這里比如說是B頁。

微信小程序?qū)嵱么a段(收藏版)

A頁:

  <view class="project_nab ovf">
    <view class="on"> 詳情 </view>
    <view class="project_item" bindtap="goitem" data-url='jd'>建檔</view>
    <view class="project_item" bindtap="goitem" data-url='cj'>產(chǎn)檢</view>
    <view class="project_item" bindtap="goitem" data-url='fm'>分娩</view>
   </view>

 goitem:function (e) {
 wx.navigateTo({
  url: '/pages/item/item?url=' + e.target.dataset.url
 })
 },

B頁:

  <view class="top1 ovf">
    <view class="" ><navigator url="/pages/hishome/hishome" open-type="navigate">詳情</navigator></view>
    <view class=" {{currentTab==0 ? 'select' : ''}}" data-current="0" bindtap="swichNav"> 產(chǎn)檢 </view>
    <view class=" {{currentTab==1 ? 'select' : ''}}" data-current="1" bindtap="swichNav"> 建檔 </view>
    <view class=" {{currentTab==2 ? 'select' : ''}}" data-current="2" bindtap="swichNav"> 分娩 </view>
  </view>

 onLoad: function (options) {
 var that = this;
 console.log(options.url)
 if (options.url === 'cj') {
  that.setData({
  currentTab: '0',
  btn: '產(chǎn)檢',
  set: 'cj'
  });
 } else if (options.url === 'jd') {
  that.setData({
  currentTab: '1',
  btn: '建檔',
  set: 'jd'
  });
 } else {
  that.setData({
  currentTab: '2',
  btn: '分娩',
  set: 'fm'
  });
 } 
 }
