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
})
})
