javascript - jQuery 可拖动和滚动不起作用 : mobile devices

Question

我正在尝试弄清楚如何使可拖动和可滚动的工作模拟:

当您尝试在任一侧拖动图像时，可拖动操作也会启动，我希望该区域可以轻松滚动，这意味着当我滚动时不应该出现 draggble 事件

 var $drop = $('#canvas-drop-area,#canvas-drop-area1'),
        $gallery = $('#image-list li'),
        $draggedImage = null,
        $canvasp1old = null,
        $canvasp2old = null;
    $gallery.draggable({
        //refreshPositions: true,
        scroll: false,
        start: function(e) {
            $draggedImage = event.target;
            $drop.css({
                'display': 'block'
            });
        },
        helper: function(e) {
            return $('<img src="' + $(this).find('img').attr("src") + '" width="'+imgwidth+'">');
        },
        stop: function() {
            $draggedImage = null;
        },
        revert: true
    });

这可能对你有帮助。

HTML

$("#draggable").draggable({
            snap: true
        });
        $("#draggable2").draggable({
            snap: ".ui-widget-header"
        });
        $("#draggable3").draggable({
            snap: ".ui-widget-header",
            snapMode: "outer"
        });
        $("#draggable4").draggable({
            grid: [20, 20]
        });
        $("#draggable5").draggable({
            grid: [80, 80]
        });

.draggable {
        width: 90px;
        height: 80px;
        padding: 5px;
        float: left;
        margin: 0 10px 10px 0;
        font-size: .9em;
    }
    .ui-widget-header p,
    .ui-widget-content p {
        margin: 0;
    }
    #snaptarget {
        height: 600px;
        width: 200px;
    }

<table>
        <tr>
            <td>
                <div id="draggable" class="draggable ui-widget-content">
                    <p>Default (snap: true), snaps to all other draggable elements</p>
                </div>

                <div id="draggable2" class="draggable ui-widget-content">
                    <p>I only snap to the big box</p>

            <td>
                <div id="snaptarget" class="ui-widget-header">
                    <p>I'm a snap target</p>
                </div>
            </td>
            <td>
                <div id="draggable3" class="draggable ui-widget-content">
                    <p>I only snap to the outer edges of the big box</p>
                </div>

                <div id="draggable4" class="draggable ui-widget-content">
                    <p>I snap to a 20 x 20 grid</p>
                </div>

                <div id="draggable5" class="draggable ui-widget-content">
                    <p>I snap to a 80 x 80 grid</p>
                </div>
            </td>
        </tr>
    </table>

javascript

$(function() {
        $("#draggable").draggable({
            snap: true
        });
        $("#draggable2").draggable({
            snap: ".ui-widget-header"
        });
        $("#draggable3").draggable({
            snap: ".ui-widget-header",
            snapMode: "outer"
        });
        $("#draggable4").draggable({
            grid: [20, 20]
        });
        $("#draggable5").draggable({
            grid: [80, 80]
        });
    });

对于移动设备，您可以使用 jquery ui touch punch 它会对您有所帮助，最好的解决方案是 here

据我所知，jquery 和 jquery-ui 在 159.8.132.20/alldevice/上运行得非常好。
