javascript - JS区分iPhone上的点击和滚动

Question

我正在尝试关闭侧边菜单 onclick。然而，touchstart 也将滚动检测为点击，touchend 也是如此。 如何只检测 iPhone 上的点击(而不是滚动)？

  $('#html').on("click touchstart",function(e) {
      var optionsmenue = $(".adminmenu_label");
      if(!optionsmenue.is(e.target) && optionsmenue.has(e.target).length === 0) {
        document.getElementById("Optionsmenu").style.width = "0%";
        document.getElementById("Optionsmenu").style.transition = "0.2s ease-out";
        document.getElementById("adblue").style.display = "block";
        document.getElementById("whatever").style.display = "block";  
        document.getElementById("not_related").style.display = "block";
        document.getElementById("still_not_related").style.display = "block"; 
        document.getElementById("still_still_not_related").style.width = "100%"; 
      }
    });

检测 iOS 并添加 cursor:pointer 对我有用，IOS 似乎有事件委托(delegate)问题。

var iOS = ["iPad","iPhone","iPod"].indexOf(navigator.userAgent) > -1;

if(iOS) {
   $('body').css({ cursor : 'pointer' });
}

$('#html').on("click",function(e) {
    // No need for touch start click will do the trick;
});
