微信小程序选项卡之跳转

　　时隔一个月之久今天再聊聊小程序吧，选项卡是在PC以及移动端经常使用的，这次在开发小程序的过程中一个选项卡可把我难住了，今天咱们就来说一下。

大多数的商城类小程序都有这个功能，点击“全部订单”，“待付款”，“待发货”，“待收货”，“已完成”，会跳转页面且跳至与之相对应的选项卡中。所以我们在开发该小程序时也做了相同的功能。如下图：

 

 

选项卡静态布局思路： 主要用到 scroll-view与 swiper标签，选项卡切换主要依靠 swiper 中的 current 属性，不懂请自行查看小程序API。
跳转页面且跳至与之相对应的选项卡思路：
首先在 app.js 中配置 globalData。
在“个人中心” js 文件中配置点击该项跳转至与之对应的 tab 的 index。
在“个人中心”跳转页面时通过 globalData 传递 index 给“全部订单”页面，“全部订单”页面通过 app.globalData.currentLocation 接受数据，改变选项卡的切换。

app.js 代码

  globalData: {
    userInfo: null
  }

个人中心 wxml 代码

<!--九宫格  -->

个人中心 js 代码

var app = getApp()
var util = require('../../utils/util.js')
var formatLocation = util.formatLocation Page({ data: { }, // 指定 全部订单 和 九宫格中按钮 点击跳转至 选项卡中 与之对应的tab allForm:function(){ app.globalData.currentLocation = 0, wx.navigateTo({ url: '../orderForm/orderForm' }) }, noPay:function(){ app.globalData.currentLocation = 1, wx.navigateTo({ url: '../orderForm/orderForm' }) }, noSend:function(){ app.globalData.currentLocation = 2, wx.navigateTo({ url: '../orderForm/orderForm' }) }, sended:function(){ app.globalData.currentLocation = 3, wx.navigateTo({ url: '../orderForm/orderForm' }) }, completed:function(){ app.globalData.currentLocation = 4, wx.navigateTo({ url: '../orderForm/orderForm' }) } })
