     message: h('p', null, [
      h('span', null, '内容可以是 '),
      h('i', { style: 'color: teal' }, 'VNode')
     ]),
     showCancelButton: true,
     confirmButtonText: '确定',
     cancelButtonText: '取消',
     beforeClose: (action, instance, done) => {
      if (action === 'confirm') {
       instance.confirmButtonLoading = true;
       instance.confirmButtonText = '执行中...';
       setTimeout(() => {
        done();
        setTimeout(() => {
         instance.confirmButtonLoading = false;
        }, 300);
       }, 3000);
      } else {
       done();
      }
     }
    }).then(action => {
