WeChat applet explains page jump and return and returns data
A page:
.wxml file
<view class="flex-wrp"> <text style="width: 32%;">选择城市</text> <input style="width: 68%;" type="text" bindtap="city" placeholder="请选择城市" value="{{cityName}}"/> </view>
.js file
Page({ data: { cityName:"深圳" #用来回传的关键字,默认深圳 }, city: function(e){ wx.navigateTo({ url: '../city/city' }) } })
After page A jumps to page B, it returns:
cityNameClick: function (event) { var cityName = event.currentTarget.dataset.cityname; console.log(cityName); var pages = getCurrentPages(); var currPage = pages[pages.length - 1]; //当前页面 var prevPage = pages[pages.length - 2]; //上一个页面 //直接调用上一个页面的setData()方法,把数据存到上一个页面中去 prevPage.setData({ cityName: cityName }) wx.navigateBack(); },
