dhtmlx tree的使用方式

步驟：

1.導入dhtmlx的相關js文件與css文件

2.進行JS調用

//定義樹
var tree;
function loadTree(){
	$('#doctree_box').html('');
	//創建一棵樹
	//參數含義 1.對應的樹div id 2,3對應長寬 4對應樹根節點ID
    tree=new dhtmlXTreeObject("doctree_box","100%","100%",0);
    //設置樣式
    tree.setSkin('dhx_skyblue');
    //設置背景圖片路徑
    tree.setImagePath( ctx+"/images/dhtmlx/csh_yellowbooks/");
    //點擊樹時出發的函數
    tree.setOnClickHandler(
        function(id){openPathDocs(id); }
    );
    //請求url
    var url=ipAddress+ctx+"/sale/orderPoolManager.do?flag=tree";
    
    tree.setXMLAutoLoading(url);
    //實現樹的展示
    tree.loadXML(url);
   
 }

點擊數的函數：

/* open path funtion */
function openPathDocs(id){
    if (tree.getUserData(id, "centerId") != null ){
        alert(tree.getUserData(id, "centerId"));
        return;
    }else{
    	alert('獲取centerId值失敗!');
    }
}

3.進行樹結構的定義,可以採用xml報文或者dom4j生成xml

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<?xml version="1.0" encoding="UTF-8"?>
<tree id='0'>
	<item id='node_1' open='1' text='XXX查詢' child='1' im0='folder.gif' im1='folderopen2.gif'
		im2="folder.gif">
		
		<!-- 此處爲動態寫入 START -->
		<item id='center_01' text='待解決(20)'  im0='page.gif' im1='page.gif' im2='page.gif'>
		    <userdata name="poolStatus">wait</userdata>
		</item>
		
		<item id='center_02' text='處理中(1)' im0='page.gif' im1='page.gif' im2='page.gif'>
			    <userdata name="poolStatus">process</userdata>
		</item>
		
	    <item id='center_03' text='已處理' im0='page.gif' im1='page.gif' im2='page.gif'>
			    <userdata name="poolStatus">done</userdata>
		</item>
		
		<!-- 此處爲動態寫入 END -->
	</item>
</tree>
