html5 横向滚动,无滚动条(transform:translate)

html5 横向滚动,用到了 touchstart、touchmove、touchend 控制修改transform:translate属性;[手机端或者浏览器模拟手机模式才有效果]

回头准备封装成插件都放到 github上  https://github.com/wt9213

html:

<div class="tab" id="tab">            <div class="scroll-tab" id="scroll_tab" style="transform: translate(0px, 0px) translateZ(0px);">                <a href="#" class="active">tab1</a>                <a href="#">tab2</a>                <a href="#">tab3</a>                <a href="#">tab4</a>                <a href="#">tab5</a>                <a href="#">tab6</a>                <a href="#">tab7</a>                <a href="#">tab8</a>            </div>        </div>

css:

.tab{overflow: hidden;width: 90%;margin: 0 auto;}.scroll-tab{display: flex;position: relative;}.scroll-tab a{padding: 5px 10px;border-bottom: 2px solid transparent;text-decoration: none;color: #333333;font-size: 16px;font-family: "arial, helvetica, sans-serif","微软雅黑";}.scroll-tab a.active{color: #0894ec;border-color: #0894ec;}

js:

    var $scrollTab;    var $tab=document.getElementById("tab");    var touchstartX, touchstartY;    var scrollMax;    var mX,mY;    var moveto;    $tab.addEventListener(‘touchstart‘, function (e) {        var touch = e.targetTouches[0];        touchstartX = touch.pageX;        touchstartY = touch.pageY;        $scrollTab=document.getElementById("scroll_tab");        scrollMax = $scrollTab.scrollWidth - $tab.clientWidth;      });    $tab.addEventListener(‘touchmove‘, function (e) {        var touch = e.targetTouches[0];        mX = touch.pageX;        mY = touch.pageY;        if (touchstartY - mY <= 15 && touchstartY - mY >= -15) {            var transform = $scrollTab.style.transform;            transform = transform.replace("translate(", "");            var currentX = Number(transform.substring(0, (transform.indexOf(",") - 2)));            moveto = -(touchstartX - mX)/4.8;              moveto = moveto + currentX;            if (moveto <= (100) && moveto >= (-scrollMax - 100)) {                $scrollTab.style.transform="translate(" + moveto + "px, 0px) translateZ(0px)";            }        }    });    $tab.addEventListener(‘touchend‘, function (e) {        $scrollTab.style.transitionDuration="600ms";        if (moveto > 0) {            $scrollTab.style.transform="translate(0px, 0px) translateZ(0px)";        } else if (moveto < (-scrollMax)) {            $scrollTab.style.transform="translate(" + (-scrollMax) + "px, 0px) translateZ(0px)";        }        setTimeout(function () {            $scrollTab.style.transitionDuration="0ms";        }, 600);    });
