自定義jquery手風琴箭頭

Question

我發現很難在Jquery手風琴中實現我的自定義圖標以覆蓋默認箭頭。

我已經創建了我的類（參見下文）

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 (-) */ 
} 

與Unicode的表現可是我有問題。 任何幫助表示讚賞，謝謝。

的content屬性用於與:before和:after僞元素，所以我想你想要做的是這樣的事情

$(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; 
 
}
