在我一直在努力的新设计中，有一个侧边栏，这意味着在使用桌面浏览时可以完全显示。在移动设备上，菜单意味着折叠成一个按钮，当点击该按钮时，该按钮应该扩展。以前的功能似乎完全正常，但后者没有;当你按下这个按钮时，似乎什么也没发生。
有人会介意帮助我调查一下并找出问题所在吗？

var layout = document.getElementById('layout'),
f - menu = document.getElementById('f-menu'),

length = classes.length,
i = 0;
for (; i < length; i++) {
if (classes[i] === className) {
classes.splice(i, 1);
break;
}
}
// The className is not found
if (length === classes.length) {
classes.push(className);
}
element.className = classes.join(' ');
}

我在评论中询问了你的variables，特别是“他们是否会抛出异常？”
他们实际上是这样做的：
SyntaxError: Unexpected token -
变量名称无效。更新这些，你的JS将开始工作。这是一个带有更新变量名称的小提琴：
