Firefox中的jquery拖放问题

标签： jquery firefox drag-and-drop

一个简单的拖放操作，三个可放置的div每个只接受一个可拖动的元素。在chrome和safari中工作，但是在firefox中，当我拖动第二个元素时，droppable元素在页面上移动。简单的html和bootstrap容器都会发生这种情况，所以我认为问题出在jquery中，但我看不出它是什么。非常感谢任何帮助。

jQuery(function ($) {
        $(".rect").draggable({revert: 'invalid',  snap: ".dropSnap",
            stack: ".draggable"} );
    
        $("#simpleregular").droppable({
            accept: "#reg",
            //accept: "#cars",
            drop: function (event, ui) {
                $(this).css("background-color", "lightgreen");
                ui.draggable.position( { of: $(this), my: 'middle bottom', at: 'middle bottom' } );
            },
            out: function (event, ui) {
                $(this).css("background-color", "")
            }
        });
    
        $("#presentcontinuous").droppable({
            accept: "#cont",
            drop: function (event, ui) {
                $(this).css("background-color", "lightgreen");
                ui.draggable.position( { of: $(this), my: 'middle bottom', at: 'middle bottom' } );
            },
            out: function (event, ui) {
                $(this).css("background-color", "")
            }
        });
        $("#simplegeneral").droppable({
            accept: "#gen",
            drop: function (event, ui) {
                $(this).css("background-color", "lightgreen");
                ui.draggable.position( { of: $(this), my: 'middle bottom', at: 'middle bottom' } );
            },
            out: function (event, ui) {
                $(this).css("background-color", "")
            }
        });
    });

所以经过一些实验和一些谷歌搜索后，我发现不是把可拖动的东西放在div中，而是使用列表项并将droppables留在div中。我猜有些浏览器只是更宽容。可拖动现在看起来像：

  <ul>
                <li id="cont" class="rect"><img src="../../images/sentence_present_continuous.png" alt="present continuous"></li>
                <li id="reg" class="rect"><img src="../../images/sentence_simple_regular.png"></li>
                <li id="gen" class="rect"><img src="../../images/sentence_simple_general.png"></li>
            </ul>

完成工作
