详解小程序不同页面之间通讯的解决方案

<navigator url="../search/search" open-type="redirect">搜索</navigator>

onLoad: function(options) {
 console.log(options.id);
}

searchRet(results) {
 console.log(results);
}

let pages = getCurrentPages();
let homePage = pages[pages.length - 2];
if (homePage) {
 homePage.searchRet(results);
}

// index.js
wx.setStorageSync('refresh', true);

// mycenter.js
if (wx.getStorageSync('refresh')) {
 // 做更新操作
 wx.removeStorageSync('refresh');
}

// select.js
const nsevent = require('nsevent');
Page({
 onLoad() {
  nsevent.on('add', (num) => {
   console.log(`select.js接收到add事件，参数为${num}`)
  }, 'select.js')
 },
 addnumber() {
  nsevent.emit('add', 1);
 },
 onUnload() {
  console.log('select.js移除add事件')
  nsevent.off('add', 'select.js');
 }
});

nsevent.emit('locationChange', { ns: ['pageA'] });
