javascript判断是否手机设备+滑动事件

//判断是否手机端

var isMobile = false;

try {

//手机端

document.createEvent("TouchEvent");

isMobile = true;

} catch (e) {

//pc

}

//手势事件

var startX = 0, endX = 0, move_left = null;

//按下时触发

$(‘元素‘).on(‘touchstart‘, function (e) {

e.preventDefault()

var touch = event.touches[0];

startX = touch.pageX;

})

//移动时触发

$(‘元素‘).on(‘touchmove‘, function (e) {

var touch2 = event.touches[0];

endX = touch2.pageX;

})

//离开时触发

$(‘元素‘).on(‘touchend‘, function (e) {

time = setInterval(picTimer, opts.Time)

if (!scrollList.is(":animated")) {

e.preventDefault()

if (startX > endX) {

index += 1;

if (index == len) { index = 0; }

showPics(index);

} else {

index -= 1;

if (index == -1) { index = len - 1; }

showPics(index);

}

}

}

不会到会，只是一个过程！
