新创建云开发官方默认模板，运行就这样了 [图片] [图片]

情景：当用户未保存数据退出页面时提示， 想法：默认激活wx.enableAlertBeforeUnload，通过参数判断控制展示隐藏。 疑问：wx.disableAlertBeforeUnload()，需要再哪里进行判断 [图片][图片]

- 当前 Bug 的表现（可附上截图） - 预期表现 - 复现路径 - 提供一个最简复现 Demo 请问下有人知道控制台这是什么错 [图片]

前一个版本在页面间传值时，采用的是将对象缓存在 app.js 中，然后在 onLoad() 中将其获取并设置为 null 的方式；在当前版本中，采用了依赖 EventChannel 进行传值的方式，但是管理后台出现大量报错，错误为 this.getOpenerEventChannel().on is not a function，本地开发工具和真机调试均无法复现该异常。 相关情况如下： 发布新版本时为全量发布；管理后台基本库最低设置为 2.7.3；报错页面无其它跳转进入途径； [图片] 相关代码如下： 第一个页面 toPrescription: function() { let that = this; util.checkUserState(-1, true, function (res) { let acceptData = { 'selectedMember': null } if (that.data.members.length > 0 && that.data.members[0].isSelf) { acceptData.selectedMember = that.data.members[0]; } wx.navigateTo({ url: '/pages/diagnosis/prescription/prescription', success: function (res) { // 通过eventChannel向被打开页面传送数据 res.eventChannel.emit('toPrescription', { data: acceptData }); } }); }); }, 第二个页面 onLoad: function(options) { let that = this; let eventChannel = this.getOpenerEventChannel(); // 监听事件，获取上一页面通过eventChannel传送到当前页面的数据 eventChannel.on('toPrescription', function (data) { let acceptData = data.data; if (acceptData && acceptData.selectedMember) { that.setData({ selectedMember: acceptData.selectedMember }); } }); }, 管理后台截图： [图片][图片]
