You have to inject MenuController in your page, and then you can access the isOpen() method.

您必须在页面中注入MenuController,然后才能访问isOpen()方法。

    import{Page, MenuController} from 'ionic-angular';

    @Page({...})
    export class MyPage {

     constructor(private menu: MenuController) {
     if menu.isOpen() {
        // do something

 }
