如何在特定视口上设置触摸手势/ hammer.js？

Question

我刚刚为我正在建设的网站构建了带有触摸事件的旋转木马滑块.目前正在尝试弄清楚如何激活或禁用(hammer)特定视口上的触摸事件.基本上一旦它到达移动/平板电脑视口.Hammer.js将禁用滑块的禁用点击控件

Answer 1

将标识符（例如类class="hammerOn"）添加到您的 div 中。
将您的hammerjs 脚本绑定到此标识符。
使用窗口调整大小功能检查窗口的当前大小。
如果窗口大小达到您不希望启用 Hammerjs 的大小，请删除该类。

基本思想：

$( window ).resize(function() {
   if (($(window).width() < yourprefwidth) && ($(window).height() < yourprefheight)) {
       $('#yourdiv').removeClass('hammerOn');
   } else {
       $('#yourdiv').addClass('hammerOn');
   }
});
