  //$("#pShow").show();
  var obj = {};
  obj.openId = myOpenId;
  obj.nickname = myNickname;// 微信昵称
  obj.headimgurl = myHeadimgurl;// 用户头像
  // obj.activityimg = "xx";//活动图片
}

Use of local storage:

/*
*注明：由于本地存储的东西，一般是可以看到的，所有有一种说法：如果是重*要的数据建议不使用这种方式。

//本地存储的运用 -存值
openId = localStorage.getItem("openId");
accesstoken = localStorage.getItem("accesstoken");

//本地存储的运用 -取值
openId = localStorage.getItem("openId");
accesstoken = localStorage.getItem("accesstoken");
