我需要有一个可以从数据库配置的jstree,我遇到了图标问题(这只是我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’)来构建此列表;属性以指向< a>中的图像.标签,但我不断显示该文件夹图标(图像不重复,但我包括它以便轻松可视化问题).
如何让jstree不显示该文件夹？似乎jstree只为整个树(或至少每个级别)构建一个图像.我不知道如何修改它.
这是上图中的html.

这就是我构建树的方式; ajax调用接收一个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",function(event){
$.jstree._reference(this).open_node(this,false);
});
解决方法
不要明确指定图标,而是使用jstree附带的
Types Plugin.然后对于每个< li>在您的html中,将其rel属性分配给您定义的类型.这是一个简单的例子：
$(function () {
$("#demo1").jstree({
"types" : {
"valid_children" : [ "web" ],"types" : {
"web" : {
"icon" : {
"image" : "/arco/Menu/images/web.png"
},},"default" : {
"valid_children" : [ "default" ]
}
}
},"plugins" : ["themes","dnd","ui","types"]
});
});
以下是树节点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>
由于您为< li>指定了rel =“web”,因此< li>将收到为web类型定义的属性,其中包括上面定义的自定义图标.
