Mmenu - 如何检测关闭的回调事件？

Question

我正在使用Jquery Mmenu plugin，我想检测何时发生关闭的回调事件，以便我可以从我的汉堡菜单中删除一个 CSS 类。我有打开和关闭菜单的相同汉堡菜单图标，我在菜单打开时添加了一个 is-active 类，但我需要检测整个菜单何时关闭，以便我可以删除该类，但我似乎无法想办法。

这是我目前所拥有的：

document.addEventListener(
    "DOMContentLoaded", () => {
        const menu = new Mmenu( "#mobile-menu", {
            "extensions": [
                "position-front"
            ],
            scrollBugFix: {
                fix: true
            },
    });
    const api = menu.API;
    const hamburger = document.querySelector('.hamburger');

    hamburger.addEventListener(
       "click", ( evnt ) => {
           evnt.preventDefault();
           hamburger.classList.add("is-active");
     });
    }
);

我在这个问题的 cmets 中找到了我的问题的答案：Callback event when jQuery 'mmenu' opened

添加：

// When the open callback event is fired bind to it and add the class
api.bind('open:after', function (){
    hamburger.classList.add('is-active');
    console.log('open')
})

// When the closed callback event is fired bind to it and remove the class
api.bind('close:after', function(){
    hamburger.classList.remove("is-active");
    console.log('closed')
})

The documentation for the plugin is good but not that great so I struggled for a while before seeing this. Maybe it can help someone else.

I am using the latest version of the plugin and that is 8 something.
