+#### 异步关闭
+
+设置`asyncClose`属性开启异步关闭，开启后可以手动调用`Dialog.close`方法关闭弹窗
+
+```javascript
+Dialog.confirm({
+  title: '标题',
+  message: '弹窗内容'
+  asyncClose: true
+})
+  .then(() => {
+    setTimeout(() => {
+      Dialog.close();
+    }, 1000);
+  })
+  .catch(() => {
+    Dialog.close();
+  });
+```

 #### 组件调用
 
-通过组件调用 Dialog 时，可以实现自定义弹窗内容、异步关闭、监听微信开放能力回调事件，具体可以参考下面的示例
