自定义jQuery手风琴箭头

Question

I'm finding it difficult to implement my custom icons in the Jquery accordion to override to default arrow.

I have created my classes in (see bellow)

Jquery

$(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 (-) */
}

Yet I'm having problems with the Unicode showing. Any help is appreciated, Thanks.

The content property is used with the :before and :after pseudo-elements, so I guess what you're trying to do is something like this

  $(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; }
