防止滑动的时候触发点击事件

手机端在滑动过程中容易引发点击事件

解决方案：

重新封装一个点击函数

//防止滑动的时候触发点击事件
function tap(sprite, cb) {
var tapStartTime = 0,
tapEndTime = 0,
tapTime = 300, //tap等待时间，在此事件下松开可触发方法
tapStartClientX = 0,
tapStartClientY = 0,
tapEndClientX = 0,
tapEndClientY = 0,
tapScollHeight = 15, //水平或垂直方向移动超过15px测判定为取消（根据chrome浏览器默认的判断取消点击的移动量)
cancleClick = false;
$(document).on('touchstart', sprite, function() {
tapStartTime = event.timeStamp;
var touch = event.changedTouches[0];
tapStartClientX = touch.clientX;
tapStartClientY = touch.clientY;
cancleClick = false;
})
$(document).on('touchmove', sprite, function() {
var touch = event.changedTouches[0];
tapEndClientX = touch.clientX;
tapEndClientY = touch.clientY;
if ((Math.abs(tapEndClientX - tapStartClientX) > tapScollHeight) || (Math.abs(tapEndClientY - tapStartClientY) > tapScollHeight)) {
cancleClick = true;
}
})
$(document).on('touchend', sprite, function() {
var _this = $(this);
tapEndTime = event.timeStamp;
if (!cancleClick && (tapEndTime - tapStartTime) <= tapTime) {
cb(_this);
}
})
}
tap(".gx_list li", function(_this) {
    var rid = _this.attr("data-i");
    console.log(rid);
})
