如何使用 Javascript 检测触摸悬停？

Question

我正在开发的 Javascript 插件有问题。这是一个轮播插件。问题是如何检测旋转木马何时被触摸一段时间；就像鼠标悬停一样。该问题伴随着“Uncaught TypeError: undefined is not a function”消息。

jQuery(function ($) {

    // settings
    var $slider = $('.slider'); // class or id of carousel slider
    var $slide = 'li'; // could also use 'img' if you're not using a li
    var $transition_time = 1000; // 1 second

    var $interval;

    function slides() {
        return $slider.find($slide);
    }

    slides().fadeOut();

    // set active classes
    slides().first().addClass('active');
    slides().first().fadeIn($transition_time);

    // auto scroll 
    function startloop() {
        $interval = setInterval(

        function () {
            var $i = $slider.find($slide + '.active').index();

            slides().eq($i).removeClass('active');
            slides().eq($i).fadeOut($transition_time);

            if (slides().length == $i + 1) $i = -1; // loop to start

            slides().eq($i + 1).fadeIn($transition_time);
            slides().eq($i + 1).addClass('active');
        }, $transition_time + $time_between_slides);
    }
    function pauseLoop() {
        window.clearInterval($interval);
    }

    $slider.hover(

    function () {
        pauseLoop(); // pause the loop
    },

    function () {
        startloop(); //scroll()
    });

    $slide.addEventListener('touchstart', function(e){
    alert ('paused');
    e.preventDefault()
    }, false);

    $slide.addEventListener('touchend', function(e){
    alert ('paused');
    startloop(); 
  e.preventDefault()
 }, false)



    return startloop();
});

试试taphold 事件。

$("div").on( "taphold", function (event) { ... } );
