移动端-解决ios连续点击页面上移问题

引入js即可

//解决ios双击页面上移问题
//在项目中测试不紧input/button这些表单控件有这个问题，p,div等也有问题，于是乎就直接在body开刀了
(function()
{
    var agent = navigator.userAgent.toLowerCase();        //检测是否是ios
    var iLastTouch = null;                                //缓存上一次tap的时间
    if (agent.indexOf('iphone') >= 0 || agent.indexOf('ipad') >= 0)
    {
        document.body.addEventListener('touchend', function(event)
        {
            var iNow = new Date()
                .getTime();
            iLastTouch = iLastTouch || iNow + 1 /** 第一次时将iLastTouch设为当前时间+1 */ ;
            var delta = iNow - iLastTouch;
            if (delta < 500 && delta > 0)
            {
                event.preventDefault();
                return false;
            }
            iLastTouch = iNow;
        }, false);
    }

})();
