var Environment = {
//mobile or desktop compatible event name, to be used with '.on' function
TOUCH_DOWN_EVENT_NAME: 'mousedown touchstart',

isAndroid: function() {
return navigator.userAgent.match(/Android/i);
},
isBlackBerry: function() {
return navigator.userAgent.match(/BlackBerry/i);
},
isIOS: function() {
return navigator.userAgent.match(/iPhone|iPad|iPod/i);
},
isOpera: function() {
return navigator.userAgent.match(/Opera Mini/i);
},
isWindows: function() {
return navigator.userAgent.match(/IEMobile/i);
},
isMobile: function() {
return (Environment.isAndroid() || Environment.isBlackBerry() || Environment.isIOS() || Environment.isOpera() || Environment.isWindows());
}
};
Your solution about using dimension is not a good solution. It relies on the actual device dimension and many other variables.
您关于使用维度的解决方案不是一个好的解决方案。它依赖于实际的设备尺寸和许多其他变量。
