小程序之獲取用戶信息取消授權處理

簡單概述一下效果：第一次點擊了取消，之后點擊的時候會一直出現獲取權限彈框

.wxml文件

<button class='mark'  wx:if="{{canIUse}}"   open-type="getUserInfo" bindgetuserinfo="bindGetUserInfo"></button>

.js文件

const app = getApp();
Page({
    data: {
        canIUse: wx.canIUse('button.open-type.getUserInfo'),

            height: null

                //設置高度，根據當前設備寬高滿屏顯示
