我使用TouchSwipe创建一个可滑动的图像列表。我将滑动事件绑定到图像,同时我还绑定了一个单击事件,该事件将打开图像的大版本。

我的问题是,如果我滑动,它也会触发点击事件。我尝试点击而不是滑动,但我无法让它工作。在此之后,我尝试event.preventDefault()event.stopPropagation()很多地方都建议这样做,但没有效果。我的最终解决方案尝试是取消绑定点击事件并在事件发生后重新绑定它,但如果我在事件函数的最后绑定事件,它会再次触发点击。

$(".js-header-swipe-image").swipe({
    swipe:function(event, direction, distance, duration, fingerCount){
        $("#details").unbind('click');//Temporary unbind, otherwise the swipe's click would trigger the gallery opening.

        //Handling swipe direction.

        $('#details').on('click', '.js-header-swipe-image', function (){//Rebind the temporary unbinded event.
            console.log('click');
            $('#modal-gallery').modal('show');
        });
    }
});

有没有办法在事件完成后中止事件本身或调用函数,以便我可以在滑动完成后重新绑定点击,这样它就不会触发重新绑定的点击?我也愿意接受任何其他解决该问题的方法。

我使用这段代码,以便仅在未滑动时触发按钮(在触摸端):

var startY;
var yDistance;

function touchHandler(event) {
    touch = event.changedTouches[0];
    event.preventDefault();
}

$('.button').on("touchstart", touchHandler, true);
$('.button').on("touchmove", touchHandler, true);

$('.button').on("touchstart", function(){
    startY = touch.clientY;
});

$('.button').on('touchend', function(){

    yDistance = startY - touch.clientY;

    if(Math.abs(yDist) < 30){

        //button response here, only if user is not swiping
        console.log("button pressed")
    }
});

基于您提供给 Tap vs Swipe 的链接

您是否尝试过以下代码?:

$(".js-header-swipe-image").swipe({
    tap: function(event, target) {
        console.log('click');
        $('#modal-gallery').modal('show');
    },
    swipe:function(event, direction, distance, duration, fingerCount){
        //Handling swipe direction.
    }
});

编辑:工作解决方案

HTML:

<style type="text/css">
    .js-header-swipe-image {
        background-color:blue;
        color:white;
        width:500px;
        height:500px;
    }
</style>
<div id="modal-gallery">
    Hello!
</div>
<div class="js-header-swipe-image">
    Swiping Div
</div>

jQuery :

<script type="text/javascript">
    $(document).ready(function() {
        $(".js-header-swipe-image").swipe({
            tap: function(event, target) {
                alert('tap');
            },
            swipe:function(event, direction, distance, duration, fingerCount){
                //Handling swipe direction.
                alert('swipe');
            }
        });
    });
</script>

当“滑动” div 时,我会收到警报swipe,当单击 div 时,我会收到警报tap

我有同样的问题。不会调用 tap 函数,因为我已经设置了threshold:0. 一旦我将其注释掉,点击事件就可以正常工作。

            container.swipe({
                touch:function(event, target) {
                    alert('touch');
                },
                tap:function(event, target) {
                    alert('tapped');
                },
                swipeLeft:function(event, direction, distance, duration, fingerCount) {
                    console.log('swipe left');
                },
                swipeRight:function(event, direction, distance, duration, fingerCount) {
                    console.log('swipe RIGHT');
                },
                swipeUp:function(event, distance, duration, fingerCount, fingerData) {
                    console.log("swipeUp from callback");
                },
                swipeDown:function(event, distance, duration, fingerCount, fingerData) {
                    console.log("swipeDown from callback");
                }
                // threshold:0
            });

    var isTouchMoving = false;



    $( "#items .item" ).on("vclick", function(){
        if(isTouchMoving){
            isTouchMoving = false;
            return false;
        }

        //do something
    });

    $(document).on('vmousemove', function(){
        isTouchMoving = true;
    });

    $(document).on('scrollstop', function(){
        isTouchMoving = false;
    });
