排名不分先后,按自己的习惯来的。
总结经验,不喜勿喷哦~

全局标题栏
"window": { "backgroundTextStyle": "light", "navigationBarBackgroundColor": "#3EC8C8", "navigationBarTitleText": "乳孕呵护", "navigationBarTextStyle": "white" }
局部标题栏
{ "usingComponents": {}, "navigationBarBackgroundColor": "#fff", "navigationBarTextStyle": "black", "navigationBarTitleText": "附近医院" }
全局底部栏
"tabBar": { "color": "#e4e4e4", "selectedColor": "#333", "list": [ { "pagePath": "pages/index/index", "text": "发现", "iconPath": "./images/find.png", "selectedIconPath": "./images/finded.png" }, { "pagePath": "pages/his/his", "text": "医院", "iconPath": "./images/his.png", "selectedIconPath": "./images/hised.png" }, { "pagePath": "pages/stu/stu", "text": "经验", "iconPath": "./images/stu.png", "selectedIconPath": "./images/stued.png" }, { "pagePath": "pages/my/my", "text": "我的", "iconPath": "./images/my.png", "selectedIconPath": "./images/myed.png" } ] }
1、wxml
<navigator url="/pages/hishome/hishome" open-type="navigate" hover-class="none"> 底部栏没有的路由 </navigator> <navigator open-type="switchTab" url="/pages/his/his" hover-class="none"> 底部栏有的路由 </navigator>
2、js
go: function (e) { wx.navigateTo({ url: '../eatxq/eatxq?id=' + e.currentTarget.dataset.id + "&name=" + e.currentTarget.dataset.name }) }
<loading hidden="{{onff}}">加载中</loading> <view>页面</view>
加载完成true
wx.request({ url: 'https://m.renyiwenzhen.com/xcx_ajax.php?action=caneatsearch', method: 'post', header: { 'content-type': 'application/x-www-form-urlencoded' // 默认值 }, data: { search: options.search }, success(res) { that.setData({ list: res.data.fllist, onff: true }) } })
<view class="txt"> <rich-text nodes="{{msg}}" ></rich-text> </view>
利用正则修改收到的数据
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' // 默认值 }, 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;'>") }) } })
1、在根目录下的utils文件夹里创建一个名为filter.wxs文件 2、写入自己要定义的条件
var xb=function (v) { var xingb='' if(v==1){ xingb="男宝宝" } else{ xingb="女宝宝" } return xingb } module.exports = { xb:xb }
3、在页面中引入使用
<wxs src="../../utils/filter.wxs" module="filter" /> <view><text>{{filter.xb(isxb)}}</text></view>
app.js
onLaunch: function () { if (wx.canIUse('getUpdateManager')) { const updateManager = wx.getUpdateManager() updateManager.onCheckForUpdate(function (res) { // 请求完新版本信息的回调 if (res.hasUpdate) { updateManager.onUpdateReady(function () { wx.showModal({ title: '更新提示', content: '新版本已经准备好,是否重启应用?', success: function (res) { // res: {errMsg: “showModal: ok”, cancel: false, confirm: true} if (res.confirm) { // 新的版本已经下载好,调用 applyUpdate 应用新版本并重启 updateManager.applyUpdate() } } }) }) updateManager.onUpdateFailed(function () { // 新的版本下载失败 wx.showModal({ title: '已经有新版本了哟~', content: '新版本已经上线啦,请您删除当前小程序,重新搜索打开哟' }) }) } }) } }
我们经常会遇到这种需求:
点击对应的的tab,这里比如说是A页。
跳转到对应项目的页面,这里比如说是B页。
A页:
<view class="project_nab ovf"> <view class="on"> 详情 </view> <view class="project_item" bindtap="goitem" data-url='jd'>建档</view> <view class="project_item" bindtap="goitem" data-url='cj'>产检</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页:
<view class="top1 ovf"> <view class="" ><navigator url="/pages/hishome/hishome" open-type="navigate">详情</navigator></view> <view class=" {{currentTab==0 ? 'select' : ''}}" data-current="0" bindtap="swichNav"> 产检 </view> <view class=" {{currentTab==1 ? 'select' : ''}}" data-current="1" bindtap="swichNav"> 建档 </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: '产检', set: 'cj' }); } else if (options.url === 'jd') { that.setData({ currentTab: '1', btn: '建档', set: 'jd' }); } else { that.setData({ currentTab: '2', btn: '分娩', set: 'fm' }); } }
