如何使用html源为jstree设置自定义图标

Question

我需要一个可从数据库配置的jstree，并且对图标有问题（这只是查询中包含图标名称的另一列） 。问题是我无法正确显示它。

我通过添加background-image:url('path');属性在<a>标签指向图像建立这个清单，但我不断收到该文件夹​​图标显示（图像不会重复，但我有它的问题easyer可视化）。

如何让jstree不显示该文件夹？看来jstree只是为整个树（或者至少每个级别）构建一个映像。我不知道如何修改。

这是上图的html。

这是我如何构建树; Ajax调用接收html列表：

$(function() { 
    $("#arbolMenu").jstree({ 
     "plugins" : [ "themes", "html_data", "cookies"], 
     "html_data" : { 
      "ajax" : { 
       "url" : "/arco/CtrlMenu", 
       "data" : function (n) { 
        return { id : n.attr ? n.attr("id") : -1 }; 
       } 
      } 
     } 
    }); 
}).delegate(".jstree-open>a", "click.jstree", function(event){ 
    $.jstree._reference(this).close_node(this, false, false); 
}).delegate(".jstree-closed>a", "click.jstree", function(event){ 
    $.jstree._reference(this).open_node(this, false, false); 
});

而不是明确指定图标，使用随jstree的Types Plugin。然后，对于您的html中的每个<li>，请将其rel属性分配给您定义的类型。下面是一个简单的例子：

$(function() { 
    $("#demo1").jstree({ 
     "types" : { 
      "valid_children" : [ "web" ], 
      "types" : { 
       "web" : { 
        "icon" : { 
         "image" : "/arco/Menu/images/web.png" 
        }, 
       }, 
       "default" : { 
        "valid_children" : [ "default" ] 
       } 
      } 
     }, 
     "plugins" : ["themes","html_data","dnd","ui","types"] 
    }); 
}); 

这里是你的树节点的HTML的示例代码段：

<li id="1227_1228" rel="web"> 
    <a href="some_value_here">Mantenimiento planificado</a> 
    <!-- UL node only needed for children - omit if there are no children --> 
    <ul> 
     <!-- Children LI nodes here --> 
    </ul> 
</li> 

既然你指定rel="web"你<li>，在<li>将收到该类型web定义的属性其中包括上面定义的自定义图标。

添加以下CSS到您的文档：

.jstree-icon { 
    display: none; 
}
