【Javascript】【事件】处理移动端触摸事件

触摸事件只对移动设备有效

    
        $(() => {
            let elem = $(".clz")[0];
            elem.ontouchstart = () => {
                console.log("on touch start");
            };
            elem.ontouchmove = () => {
                console.log("on touch move");
            };
            elem.ontouchend = () => {
                console.log("on touch end");
            };
        });
    

版本比较低的移动设备，可能不支持ontouch方法，需要使用addEventListener方法来代替

    
        $(() => {
            let elem = $(".clz")[0];
            elem.addEventListener("touchstart", () => {
                console.log("on touch start");
            });
            elem.addEventListener("touchmove", () => {
                console.log("on touch move");
            });
            elem.addEventListener("touchend", () => {
                console.log("on touch end");
            });
        });
