如何使用Jquery / Javascript在运行Windows的PC上实现触摸功能？

我已经使用这些代码在我的网站上实现了触摸功能,它适用于iPad / iPhone.

// registering touch events
function initTouchEvents() {

    // if a device is a touch device
    if (window.Touch) {
        document.addEventListener("touchstart", touchHandler, true);
        document.addEventListener("touchmove", touchHandler, true);
        document.addEventListener("touchend", touchHandler, true);
        document.addEventListener("touchcancel", touchHandler, true);
    }
}

// making items sortable in touch screen devices
function touchHandler(event) {

    var touches = event.changedTouches,
                    first = touches[0],
                    type = "";

    switch (event.type) {
        case "touchstart": type = "mousedown"; break;
        case "touchmove": type = "mousemove"; break;
        case "touchend": type = "mouseup"; break;
        default: return;
    }
    var simulatedEvent = document.createEvent("MouseEvent");
    simulatedEvent.initMouseEvent(type, true, true, window, 1, first.screenX, first.screenY,
                                  first.clientX, first.clientY, false, false, false, false, 0/*left*/, null);

    first.target.dispatchEvent(simulatedEvent);

    if (event.type == "touchmove") {

        event.preventDefault();
    }
}

但是当我在触摸屏电脑上测试我的网站时,它没有运行,我发现了window.Touch只适用于iPhone / iPad.我还尝试了各种其他事件,如typeof(window.ontouchstart！=’undefined’)和(‘ontouchstart’在窗口|| typeof TouchEvent！=“undefined”)但它没有检测到它是触摸屏而不是注册活动以进行触摸移动.

我在这里问的是,javascript中的一个事件可以检测所有触摸设备(IOS / Android / Windows / OSX)并运行注册事件.

解决方法:

Phantom Limb使桌面浏览器模拟触摸事件
