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": "附近醫院"
}
全局底部欄
"tabBar": {

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
})
}
<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
})
}
})
<view class="txt">
<rich-text nodes="{{msg}}" ></rich-text>
</view>
利用正則修改收到的數據
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;'>")
})
}
})
1、在根目錄下的utils文件夾里創建一個名為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>
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
if (res.hasUpdate) {
updateManager.onUpdateReady(function () {
wx.showModal({
title: '更新提示',
content: '新版本已經準備好，是否重啟應用？',
success: function (res) {
// res: {errMsg: “showModal: ok”, cancel: false, confirm: true}
if (res.confirm) {
// 新的版本已經下載好，調用 applyUpdate 應用新版本并重啟
updateManager.applyUpdate()
}
}
})
})
updateManager.onUpdateFailed(function () {
// 新的版本下載失敗
wx.showModal({
title: '已經有新版本了喲~',
content: '新版本已經上線啦，請您刪除當前小程序，重新搜索打開喲'
})
})
}
})
}
}
我們經常會遇到這種需求：
點擊對應的的tab，這里比如說是A頁。
跳轉到對應項目的頁面，這里比如說是B頁。
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'
});
}
}
