微信小程序值找不到 传参没有数据undefined 使用onfire

1.data-questionId的驼峰式命名是不行的必须小写

2.没有设置的合法域名去请求数据也会影响

另外可以使用onfire方法传值
通过onfire.js为来实现这个效果
onfire.js的下载地址https://github.com/hustcc/onfire.js

使用思路：

A 页面先订阅一个事件，并定义处理方法；
从 B 页面返回时，发送消息；
A 页面卸载时，解除订阅。

方式:

var onfire = require("../utils/onfire.js");
var that;
var eventObj = onfire.on('key', function () {
    // 当消息被传递时，做具体的事
});
Page({
  data: {
  },
  onLoad: function(options) {
    // Do some initialize when page load.
  },
  onReady: function() {
    // Do something when page ready.
  },
  onUnload: function (e) {
    onfire.un('key');
    onfire.un(eventObj);//移除
  }
var eventObj = onfire.on('key', function (data){
  // 执行操作
})
})
