javascript - 移动端的 jQuery 点击事件

Question

我在移动设备上遇到了 JQuery 单击事件的问题。我搜索了 SO 以寻找答案，并发现了关于在 Safari/Chrome 等移动浏览器中工作的点击事件的相互矛盾的建议。

下面是我的 Pen，它是一个更大元素的片段。这是我为了这篇文章的目的在 5 分钟内拼凑起来的东西。

JS 被执行并且 CSS 类在桌面浏览器上被切换，但在移动设备上根本没有。我错过了什么？

你可以尝试像这样检测触摸事件的事件委托(delegate)//检测是否支持触摸

var event= ('ontouchstart' in document.documentElement) ? "touchstart" : "click";

//委托(delegate)合适的事件

$(".btn-navbar-responsive").on(event, function() {
    $(".navbar-menu").toggleClass("navbar-hidden navbar-visible");
});
