Question

我发现很难在Jquery手风琴中实现自定义图标以覆盖默认箭头。

我已经创建了我的课程（见下文）

Jquery的

$(function () {
   var icons = {
      header: "iconClosed",    // custom icon class
      activeHeader: "iconOpen" // custom icon class
   };
   $("#accordion").accordion({
       icons: icons,
       heightStyle: "content"
   });
   $('#accordion input[type="checkbox"]').click(function (e) {
       e.stopPropagation();
   });
});

CSS

.ui-icon.iconOpen {
    content: '\02795'; /* Unicode character for "plus" sign (+) */
    font-size: 13px;
    color: #777;
    float: right;
    margin-left: 5px;
}
.ui-icon.iconClosed {
    content: "\2796"; /* Unicode character for "minus" sign (-) */
}

然而我的Unicode显示有问题。感谢任何帮助，谢谢。

content属性与:before和:after伪元素一起使用，所以我想你要做的是这样的

 $(function () {
            var icons = {
                header: "iconClosed",    // custom icon class
                activeHeader: "iconOpen" // custom icon class
            };
            $("#accordion")
                .accordion({
                    icons: icons,
                    heightStyle: "content"
                });
            $('#accordion input[type="checkbox"]').click(function (e) {
                e.stopPropagation();
            });
        });

.ui-icon.iconOpen:after {
    content: '\02795'; /* Unicode character for "plus" sign (+) */
    font-size: 13px;
    color: #777;
    float: right;
    margin-left: 5px;
}
.ui-icon.iconClosed:after {
    content: "\2796"; /* Unicode character for "minus" sign (-) */
    font-size: 13px;
    color: #777;
    float: right;
    margin-left: 5px;
}
