1.使用 icon
. 首先 进入 Ztree 官网 查看 Api ： http://www.treejs.cn/v3/api.php
你可以下载官网上的ztree压缩包，在里面有 自定义图标的实例代码：
首先使用静态数据来更改节点图标：
var zNodes =[
{ id:1, pid:0, name:"展开、折叠 自定义图标不同",open:true},
{ id:11, pid:1, name:"叶子节点1", icon:"${ctxStatic}/jquery- ztree/3.5.12/css/zTreeStyle/img/diy/2.png"},
{ id:12, pid:1, name:"叶子节点2", icon:"${ctxStatic}/jquery-ztree/3.5.12/css/zTreeStyle/img/diy/9.png"},
{ id:13, pid:1, name:"叶子节点3", icon:"${ctxStatic}/images/hospital.png"},
{ id:2, pid:0, name:"展开、折叠 自定义图标相同", open:true},
{ id:21, pid:2, name:"叶子节点1"},
{ id:22, pid:2, name:"叶子节点2"},
{ id:23, pid:2, name:"叶子节点3"}
]; 叶子节点3使用的是自己项目中的图片，你不可以将图片放入ztree的文件中，否则无法加载出来
核心就是 icon；" "
效果图：
使用动态数据更改图标：
要注意在对应的实体类中 ：添加 icon 的字段，并设置 get /set 方法
实体类：
private boolean isParent;
private String id;
private String pid;
private String icon;
public boolean getIsParent() {
return isParent;
}
public void setIsParent(boolean isParent) {
this.isParent = isParent;
}
public String getIcon() {
return icon;
}
public void setIcon(String icon) {
this.icon = icon;
}controller：
for(int i=0;i<orgList.size();i++) {
orgList.get(i).setIcon("/Datavalid/static/images/hospital.png");
}jsp：
<%@ page contentType="text/html;charset=UTF-8"%>
<%@ include file="/webpage/framework/include/taglib.jsp"%>
<html>
<head>
<title></title>
<meta name="decorator" content="default" />
<%@include file="/webpage/framework/include/treeview.jsp"%>
<script type="text/javascript">
var setting = {
view:{
showIcon:true
},
data : {
simpleData : {
enable : true,
idKey : "id",
pIdKey : "pid",
}
},
callback : {
onClick : zTreeOnclick
}
};
$(document).ready(function() {
initZTree();
});
function initZTree() {
$.ajax({
url : "${ctx}/datavalid/dataSource/areaOrgData",
type : "post",
dataType : "json",
success : function(data) {
$.fn.zTree.init($("#ztree"), setting, data);
},
error : function() {
}
});
}
function zTreeOnclick(event, treeId, treeNode) {
if (treeNode.orgName != null) {
window.parent.document.getElementById("orgName").value = ""
+ treeNode.orgName;
window.parent.document.getElementById("orgCode").value = ""
+ treeNode.orgCode;
//关闭此页面
var index = parent.layer.getFrameIndex(window.name);
parent.layer.close(index);
}
};
</script>
</head>
<body>
<ul id="ztree" class="ztree"></ul>
</body>
</html>效果图：
2.使用 iconSkin
同样的首先查看 zTree 的API，或者查看 ztree 压缩包里面的 iconSkin的实例，下面是实例的代码：
<!DOCTYPE html>
<HTML>
<HEAD>
<TITLE> ZTREE DEMO - Custom Icon Skin </TITLE>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<link rel="stylesheet" href="../../../css/demo.css" type="text/css">
<link rel="stylesheet" href="../../../css/zTreeStyle/zTreeStyle.css" type="text/css">
<script type="text/javascript" src="../../../js/jquery-1.4.4.min.js"></script>
<script type="text/javascript" src="../../../js/jquery.ztree.core.js"></script>
<!-- <script type="text/javascript" src="../../../js/jquery.ztree.excheck.js"></script>

<SCRIPT type="text/javascript">
<!--
var setting = {
data: {
simpleData: {
enable: true
}
}
};
var zNodes =[
{ id:1, pId:0, name:"Custom Icon 01", open:true, iconSkin:"pIcon01"},
{ id:11, pId:1, name:"leaf node 01", iconSkin:"icon01"},
{ id:12, pId:1, name:"leaf node 02", iconSkin:"icon02"},
{ id:13, pId:1, name:"leaf node 03", iconSkin:"icon03"},
{ id:2, pId:0, name:"Custom Icon 02", open:true, iconSkin:"pIcon02"},
{ id:21, pId:2, name:"leaf node 01", iconSkin:"icon04"},
{ id:22, pId:2, name:"leaf node 02", iconSkin:"icon05"},
{ id:23, pId:2, name:"leaf node 03", iconSkin:"icon06"},
{ id:3, pId:0, name:"no Custom Icon", open:true },
{ id:31, pId:3, name:"leaf node 01"},
{ id:32, pId:3, name:"leaf node 02"},
{ id:33, pId:3, name:"leaf node 03"}
];
$(document).ready(function(){
$.fn.zTree.init($("#treeDemo"), setting, zNodes);
});
//-->
</SCRIPT>
<style type="text/css">
.ztree li span.button.pIcon01_ico_open{margin-right:2px; background: url(../../../css/zTreeStyle/img/diy/1_open.png) no-repeat scroll 0 0 transparent; vertical-align:top; *vertical-align:middle}
.ztree li span.button.pIcon01_ico_close{margin-right:2px; background: url(../../../css/zTreeStyle/img/diy/1_close.png) no-repeat scroll 0 0 transparent; vertical-align:top; *vertical-align:middle}
.ztree li span.button.icon01_ico_docu{margin-right:2px; background: url(../../../css/zTreeStyle/img/diy/3.png) no-repeat scroll 0 0 transparent; vertical-align:top; *vertical-align:middle}
</style>
</HEAD>
<BODY>
<h1>Custom Icon - iconSkin</h1>
<h6>[ File Path: core/custom_iconSkin.html ]</h6>
<div class="content_wrap">
<div class="zTreeDemoBackground left">
<ul id="treeDemo" class="ztree"></ul>
</div>
</div>
</BODY>
</HTML>看实例代码就知道，iconSkin 的值 xxxxx 就对应着 button.xxxxx._____ ，所以我们只要给某节点 设置 iconSkin，然后在对应的button设置那个 iconSkin的值就行
下面看我的代码：
实体类：
private boolean isParent;
private String id;
private String pid;
private String iconSkin;
public String getIconSkin() {
return iconSkin;
}
public void setIconSkin(String iconSkin) {
this.iconSkin = iconSkin;
}mybatis文件
<select id="findOrgList" resultType="RegionOrg">
SELECT
ORG_NAME as "orgName",
ORG_CODE as "orgCode",
AREA_CODE as "pid",
ORG_NAME as "name",
'hospital' as "iconSkin"
FROM
TB_ORGANIZATION where
AREA_CODE = #{id}
order by AREA_CODE
</select>'hospital' as "iconSkin" ， 我在查询时，顺便将 iconSkin 的值设为 hospital
jsp页面
<%@ page contentType="text/html;charset=UTF-8"%>
<%@ include file="/webpage/framework/include/taglib.jsp"%>
<html>
<head>
<title>地区机构绑定</title>
<meta name="decorator" content="default" />
<%@include file="/webpage/framework/include/treeview.jsp"%>
<script type="text/javascript">
var setting = {
data : {
simpleData : {
enable : true,
idKey : "id",
pIdKey : "pid",
}
},
callback : {
onClick : zTreeOnclick
}
};
$(document).ready(function() {
initZTree();
});
function initZTree() {
$.ajax({
url : "${ctx}/datavalid/dataSource/areaOrgData",
type : "post",
dataType : "json",
success : function(data) {
$.fn.zTree.init($("#ztree"), setting, data);
},
error : function() {
}
});
}
function zTreeOnclick(event, treeId, treeNode) {
if (treeNode.orgName != null) {
window.parent.document.getElementById("orgName").value = ""
+ treeNode.orgName;
window.parent.document.getElementById("orgCode").value = ""
+ treeNode.orgCode;
//关闭此页面
var index = parent.layer.getFrameIndex(window.name);
parent.layer.close(index);
}
};
</script>
<style type="text/css">
.ztree li span.button.hospital_ico_docu{margin-right:2px; background: url(${ctxStatic}/images/hospital.png) no-repeat scroll 0 0 transparent; vertical-align:top; *vertical-align:middle}
</style>
</head>
<body>
<ul id="ztree" class="ztree"></ul>
</body>
</html>和icon的方法只是 加了个
<style type="text/css">
.ztree li span.button.hospital_ico_docu{margin-right:2px; background: url(${ctxStatic}/images/hospital.png) no-repeat scroll 0 0 transparent; vertical-align:top; *vertical-align:middle}
</style>
效果和icon 完全一样：
icon 与 iconSkin的比较：
我说说我的理解，不知道是否正确。
我认为用 iconSkin 开发起来更加容易进行维护，耦合性更低
从我上述的代码也知道，我在使用icon的时候，使用绝对路径去设置Icon的值，
而使用iconSkin，仅仅只设置 了一个名称，获取图片的任务交给了Jsp，
这样在维护的时候，可以不用去寻找、修改的后台代码，只需找到对应的jsp页面修改
我个人推荐使用iconSkin
