dhtmlXTreeObject
最近做树形菜单，用dhtmlXTreeObject 加载json代码
tree2=new dhtmlXTreeObject("treeboxbox_tree2","100%","100%",0);
tree2.setImagePath("<%=request.getContextPath()%>/functiontree/csh_scbrblue/");
tree2.enableCheckBoxes(1);
tree2.enableThreeStateCheckboxes(true);
tree2.setDataMode("json");
tree2.loadJSON("");
加载的json为[{"checked":"","cls":"","id":"1","im0":"leaf.gif","im1":"folderOpen.gif","im2":"folderClosed.gif","item":[{"checked":"","cls":"","id":"11","im0":"leaf.gif","im1":"folderOpen.gif","im2":"folderClosed.gif","item":[],"open":"1","text":"发送短信","url":""}],"open":"1","text":"短信发送","url":""},{"checked":"","cls":"","id":"2","im0":"leaf.gif","im1":"folderOpen.gif","im2":"folderClosed.gif","item":[{"checked":"","cls":"","id":"21","im0":"leaf.gif","im1":"folderOpen.gif","im2":"folderClosed.gif","item":[{"functionId":"211","functionName":"查询","functionUrl":"/company/contacts/list.html","parentFunctionId":"21","type":2},{"functionId":"212","functionName":"编辑","functionUrl":"/company/contacts/edit","parentFunctionId":"21","type":2},{"functionId":"213","functionName":"删除","functionUrl":"/company/contacts/delete.html","parentFunctionId":"21","type":2},{"functionId":"214","functionName":"批量删除","functionUrl":"/company/contacts/plenty-delete","parentFunctionId":"21","type":2},{"functionId":"215","functionName":"移动到组","functionUrl":"/company/contacts/edit/group","parentFunctionId":"21","type":2},{"functionId":"216","functionName":"导出","functionUrl":"/company/contacts/export/","parentFunctionId":"21","type":2},{"functionId":"217","functionName":"导入","functionUrl":"/company/contacts/import","parentFunctionId":"21","type":2},{"functionId":"218","functionName":"管理分组","functionUrl":"/company/contacts/group","parentFunctionId":"21","type":2}],"open":"1","text":"联系人","url":""},{"checked":"","cls":"","id":"22","im0":"leaf.gif","im1":"folderOpen.gif","im2":"folderClosed.gif","item":[],"open":"1","text":"已删除联系人","url":""}],"open":"1","text":"通讯录","url":""},{"checked":"","cls":"","id":"3","im0":"leaf.gif","im1":"folderOpen.gif","im2":"folderClosed.gif","item":[],"open":"1","text":"素材管理","url":""},{"checked":"","cls":"","id":"4","im0":"leaf.gif","im1":"folderOpen.gif","im2":"folderClosed.gif","item":[],"open":"1","text":"统计报表","url":""},{"checked":"","cls":"","id":"5","im0":"leaf.gif","im1":"folderOpen.gif","im2":"folderClosed.gif","item":[],"open":"1","text":"财务管理","url":""},{"checked":"","cls":"","id":"6","im0":"leaf.gif","im1":"folderOpen.gif","im2":"folderClosed.gif","item":[],"open":"1","text":"用户管理","url":""}]
