Javascript 如何在没有任何库的情况下使用jquery滑动？

我需要创建类似jQuery mobile的滑动手势

$（“#slider ul li div”）.swipleft（）使用核心jQuery而不使用任何库或插件，甚至jquerymobile

我知道jquerymobilewidget现在将被解耦，这样我们就可以单独使用swipe了。但我不能等那么久

我需要一些手动jQuery代码，类似于用于左右滑动功能的滑动手势。
我看到了，但我不明白如何从中获得滑动手势。
有人能帮我解决这个问题吗？
这是使用javascript进行触摸滑动的代码。最后，我发现很难在互联网上搜索。感谢。下面是slider的HTML代码

<div id="slider" ontouchstart="touchStart(event,'slider');" ontouchend="touchEnd(event);" 
ontouchmove="touchMove(event);" ontouchcancel="touchCancel(event);">
<ul id="slideul"><li><img src="1.jpg"></li><li>....</ul>
</div>

您可以在这里查看一下jQuery移动团队是如何做到的：我认为jQuery移动事件的原始创建者：这是一些很好的代码，它可以工作，但是，如果我在滑块中有链接，它将无法通过。它检测到触摸
var triggerElementID = null; // this variable is used to identity the triggering element
var fingerCount = 0;
var startX = 0;
var startY = 0;
var curX = 0;
var curY = 0;
var deltaX = 0;
var deltaY = 0;
var horzDiff = 0;
var vertDiff = 0;
var minLength = 72; // the shortest distance the user may swipe
var swipeLength = 0;
var swipeAngle = null;
var swipeDirection = null;

// The 4 Touch Event Handlers

// NOTE: the touchStart handler should also receive the ID of the triggering element
// make sure its ID is passed in the event call placed in the element declaration, like:
// <div id="picture-frame" ontouchstart="touchStart(event,'picture-frame');"  ontouchend="touchEnd(event);" ontouchmove="touchMove(event);" ontouchcancel="touchCancel(event);">

function touchStart(event,passedName) {
    // disable the standard ability to select the touched object
    event.preventDefault();
    // get the total number of fingers touching the screen
    fingerCount = event.touches.length;
    // since we're looking for a swipe (single finger) and not a gesture (multiple fingers),
    // check that only one finger was used
    if ( fingerCount == 1 ) {
        // get the coordinates of the touch
        startX = event.touches[0].pageX;
        startY = event.touches[0].pageY;
        // store the triggering element ID
        triggerElementID = passedName;
    } else {
        // more than one finger touched so cancel
        touchCancel(event);
    }
}

function touchMove(event) {
    event.preventDefault();
    if ( event.touches.length == 1 ) {
        curX = event.touches[0].pageX;

    if ( fingerCount == 1 && curX != 0 ) {

        swipeLength = Math.round(Math.sqrt(Math.pow(curX - startX,2) + Math.pow(curY - startY,2)));
        // if the user swiped more than the minimum length, perform the appropriate action
        if ( swipeLength >= minLength ) {
            caluculateAngle();
