callout 也是 就闪现一下没了。。

wx.setStorage

在网上也有人遇见同样的问题了 解决方案：在app.js中还没有给globalData赋值时却提前跳转到了调用globalData数据的页面，所以导致渲染失败，个人建议做个引导或加载页面，给数据一个缓冲的过程； 我在App.js里的代码 [代码]App({[代码][代码]  [代码][代码]onLaunch: [代码][代码]function[代码] [代码]() {[代码][代码]    [代码][代码]this[代码][代码].getOpenid().then(()=>{[代码][代码]        [代码][代码]return[代码] [代码]that.setAdmin()[代码][代码]    [代码][代码]})[代码][代码]  [代码][代码]},[代码][代码]  [代码][代码]getOpenid: [代码][代码]function[代码] [代码]() {[代码][代码]      [代码][代码]var[代码] [代码]that = [代码][代码]this[代码][代码]      [代码][代码]return[代码] [代码]new[代码] [代码]Promise([代码][代码]function[代码] [代码](resolve, reject) {[代码][代码]          [代码][代码]wx.getStorage({[代码][代码]              [代码][代码]key: [代码][代码]'openid'[代码][代码],[代码][代码]              [代码][代码]success: [代码][代码]function[代码] [代码](res) {[代码][代码]                 [代码][代码]that.globalData.openId = res.data[代码][代码]                 [代码][代码]return[代码] [代码]resolve([代码][代码]'app.js login success'[代码][代码])[代码][代码]              [代码][代码]},[代码][代码]              [代码][代码]fail: [代码][代码]function[代码] [代码]() {[代码][代码]                  [代码][代码]wx.login({[代码][代码]                      [代码][代码]success: res => {[代码][代码]                          [代码][代码]var[代码] [代码]code = res.code;
