无法将自定义光标添加到可排序（jQuery、CSS）

Question

我正在尝试为可排序对象自定义光标，但没有成功。但是，我可以将光标更改为 'move'。在 css 中，我有光标：url(../images/cursor.png) 并且浏览器成功找到了图像。对于所有其他元素，我能够将图像添加到光标，但不能进行排序。下面是我的可排序代码。基本上我有两列元素，我可以将元素从一列拖到另一列，反之亦然。

var categoriesCombArr = [1, 2, 3, 4, 5 , 6, 7, 8];
var category1Arr = [1, 2, 3, 4];


$(function() {
    $("#column1, #column2").sortable({
        connectWith: ".column", 
    });
});



for (i = 0; i < categoriesCombArr.length; i++) {
        if (i < category1Arr.length) {
            $("#column1").append("<div class='choice'><div class = 'image' id = 'choice" + i + "'></div><div class = 'imageDescription'><p>" + categoriesCombArr[i] + "</p></div> </div>");
        } else {
            $("#column2").append("<div class='choice'><div class = 'image' id = 'choice" + i + "'></div><div class = 'imageDescription'><p>" + categoriesCombArr[i] + "</p></div> </div>");
        }

    }

.choice {
    position: relative;
    width: 100px;
    height: 50px;
    
    display: inline-block;
    font-size: 20px;
    cursor: pointer;
    text-align: center;
    text-decoration: none;
    outline: none;
    border: none;
    margin: auto;
    font-family: SansPro-Regular;
    border-radius: 10px;
    background-color: rgb(181, 152, 113);
    margin-top: 7px;
    cursor: url(../images/cursor.png) !important;
}

.choice:hover {
    background-color: #bd7737;
    box-shadow: inset 0px 5px 8px 0px rgba(43, 27, 0, 0.34);
    cursor: url(../images/cursor.png) !important;
}




#column1{
    position: relative;
    width: 100px;
    height: 500px;
    float: left;
    /*! left: 200px; */
    text-align: center;
    
    
    top: 19px;
    overflow: scroll;
    left: 35px;
}

#column2{
    width: 100px;
    height: 500px;
    position: relative;
    float: right;   
    /*! right: 200px; */
    
    text-align: center;
    left: -36px;
    overflow: scroll;
}

你能看下这段代码吗，也许对你有帮助。

此致，

$( function() {
    $( "#sortable" ).sortable({
      cancel: ".noSortable"
    });
   
    $( "#sortable" ).disableSelection();
  } );

body {
 font-family: Arial, Helvetica, sans-serif;
}

table {
 font-size: 1em;
}

.ui-draggable, .ui-droppable {
 background-position: top;
}

#sortable { list-style-type: none; margin: 0; padding: 0; width: 60%; }
  #sortable li { margin: 0 3px 3px 3px; padding: 0.4em; padding-left: 1.5em; font-size: 1.4em; height: 18px;cursor:move; }
#sortable li.noSortable{cursor:no-drop;}
  #sortable li span { position: absolute; margin-left: -1.3em; }

<link href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css" rel="stylesheet"/>
<ul id="sortable">
  <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 1</li>
  <li class="ui-state-default noSortable">Item 2</li>
  <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 3</li>
  <li class="ui-state-default noSortable">Item 4</li>
  <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 5</li>
  <li class="ui-state-default noSortable">Item 6</li>
  <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 7</li>
</ul>

我只是在查看 this article 时偶然发现了答案。看起来当您使用 URL 中的自定义光标时，您还需要从内置光标中指定一个备份光标，如下所示：

cursor: url(../images/cursor.png), move;

这大概是为了让浏览器知道在图像不可用时使用什么。

您还可以指定游标列表，浏览器将使用第一个有效的游标：

cursor: url(unavailable.png), url(../images/cursor.png), move;
