微信小程序之scroll-view选项卡与跳转 (一)

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:

scroll-view与跳转.gif


但是我们在最后做交互的时候,并没有使用该效果,下篇再说这个!先说说这个效果是如何实现的!

选项卡静态布局思路:  主要用到 scroll-viewswiper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
  }
