  // Callback of onCheckForUpdate
  console.log(res.hasUpdate)

updateManager.onUpdateReady(function () {
  my.confirm({
    title: 'Update reminder',
    content: 'The new version is ready. Do you want to restart the mini program?',
    success: function (res) {
      if (res.confirm) {
        // The new version is downloaded. Call UpdateManager.applyUpdate to restart and apply the new version.
        updateManager.applyUpdate()
      }
