父页面
const app = getApp() Page({ jump: function () { wx.navigateTo({ url: './test',
events: { //监听父acceptDataFromOpenedPage acceptDataFromOpenedPage: function (data
) { console.log(data) }, }, success: function (res) {
//触发子acceptDataFromOpenerPage res.eventChannel.emit('acceptDataFromOpenerPage',
{ data: 'send from opener page' }) } }) }, })
子页面
Page({ onLoad: function (option) { //获取EventChannel对象 const eventChannel = this
.getOpenerEventChannel() // 触发父acceptDataFromOpenedPage eventChannel.emit(
'acceptDataFromOpenedPage', { data: 'send from opened page' }); //
监听子acceptDataFromOpenerPage eventChannel.on('acceptDataFromOpenerPage', function
(data) { console.log(data) }) } })
