使用tree的左边菜单+多iframe实现的tab 实战

通常系统的主页面，左侧是菜单，右侧是tab按钮以及页面内容，这里给出实现的主要代码：

一：关于左侧菜单的实现：

1.1.后台java代码

1.1.1.表结构,SQL

最主要的字段就是SYS_MENU_ID:系统菜单ID，SYS_MENU_NAME:菜单名，SUP_SYS_MENU_ID：上级菜单ID。

使用mybatis查询sql语句：

<select id="querySysMenuAll"  resultMap="Result"  parameterType="com.asiainfo.psm.common.modal.SysMenu" >
SELECT
B.SYS_MENU_ID AS "menu_id",
B.SYS_MENU_NAME AS "menu_name",
B.SUP_SYS_MENU_ID AS "parentid",
B.ORDER_SEQ  AS "orderSeq",
B.SYS_MODULAR_ID  AS "sysModularId"
FROM
SYSTEM_MENU B
<where>
<if test="menu_id != null and menu_id != ''">
AND B.SYS_MENU_ID = #{menu_id,jdbcType=INTEGER}
</if>
</where>
</select>

1.1.2.SysMenu 系统菜单实体Bean

SysMenu.java

import java.io.Serializable;

/***
* @SysMenu 系统菜单
*
* @author wlw @
*/
public class SysMenu implements Serializable {

private static final long serialVersionUID = 1L;

//用户ID
private String userId;

// 系统菜单ID
private int menu_id;

// 系统菜单名称
private String menu_name;

// 上级系统菜单ID，如果是根系统菜单，值为0
private String parentid;

// 展现顺序，特指同级兄弟间的展现顺序
private String orderSeq;

//业务模块ID
private String sysModularId;

//菜单级别
private String menuflag;

//图标链接
private String imgurl;

private String url;

private String isLastNode;

public String getUserId() {
return userId;
}

public void setUserId(String userId) {
this.userId = userId;
}

public int getMenu_id() {
return menu_id;
}

public void setMenu_id(int menu_id) {
this.menu_id = menu_id;
}

public String getMenu_name() {
return menu_name;
}

public void setMenu_name(String menu_name) {
this.menu_name = menu_name;
}

public String getParentid() {
return parentid;
}

public void setParentid(String parentid) {
this.parentid = parentid;
}

public String getMenuflag() {
return menuflag;
}

public void setMenuflag(String menuflag) {
this.menuflag = menuflag;
}

public String getImgurl() {
return imgurl;
}

public void setImgurl(String imgurl) {
this.imgurl = imgurl;
}

public String getUrl() {
return url;
}

public void setUrl(String url) {
this.url = url;
}

public String getIsLastNode() {
return isLastNode;
}

public void setIsLastNode(String isLastNode) {
this.isLastNode = isLastNode;
}

public String getOrderSeq() {
return orderSeq;
}

public void setOrderSeq(String orderSeq) {
this.orderSeq = orderSeq;
}

public String getSysModularId() {
return sysModularId;
}

public void setSysModularId(String sysModularId) {
this.sysModularId = sysModularId;
}

@Override
public String toString() {
return "SysMenu [menu_id=" + menu_id + ", menu_name=" + menu_name + ", parentid=" + parentid + ", menuflag="
+ menuflag + ", imgurl=" + imgurl + ",url=" + url + "]";
}
}

1.1.3.Node 节点类 拼接树json结构

Node.java

package com.asiainfo.psm.common.util;

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.Iterator;
import java.util.List;

/**
* 节点工具类
* @author sww
*
*/
public class Node {
/**
* 节点编号
*/
public String id;

/**
* 节点内容
*/
public String name;

/**
* 父节点编号
*/
public String parentId;

/**
* 菜单等级
*/
public String menuflag;

/**
* 菜单图标路径
*/
public String imgUrl;

/**
* 路径
*/
public String url;

/**
* 兄弟节点排序
*/
public String orderSeq;

/**
* 业务模块ID
*/
public String sysModularId;

/**
* 孩子节点列表
*/
private List children = new ArrayList();

// 添加孩子节点
public void addChild(Node node) {
children.add(node);
}

// 先序遍历，拼接JSON字符串
public String toString() {
String result = "{" + "id : '" + id + "'" + ", name : '" + name + "'" + ", menuflag : '" + menuflag + "'"
+ ", imgUrl : '" + imgUrl + "'" + ", orderSeq : '" + orderSeq + "'" + ", sysModularId : '"
+ sysModularId + "'" + ", url : '" + url + "'";
if (children.size() != 0) {
result += ", submenu : [";
for (Iterator it = children.iterator(); it.hasNext();) {
result += ((Node) it.next()).toString() + ",";
}
result = result.substring(0, result.length() - 1);
result += "]";
} else {
result += ", leaf : true";
}
return result + "}";
}

// 兄弟节点横向排序
public void sortChildren() {
if (children.size() != 0) {
// 对本层节点进行排序（可根据不同的排序属性，传入不同的比较器，这里传入ID比较器）
Collections.sort(children, new NodeIDComparator());
// 对每个节点的下一层节点进行排序
for (Iterator it = children.iterator(); it.hasNext();) {
((Node) it.next()).sortChildren();
}
}
}
}

/**
* 节点比较器
*/
class NodeIDComparator implements Comparator {
// 按照节点编号比较
public int compare(Object o1, Object o2) {
int j1 = Integer.parseInt(((Node) o1).id);
int j2 = Integer.parseInt(((Node) o2).id);
return (j1 < j2 ? -1 : (j1 == j2 ? 0 : 1));
}
}

1.1.4.控制层处理查询菜单sql

@RequestMapping("/profile/showMenuTree.action")
public ModelAndView showMenuTree(HttpServletRequest request) {
ModelMap model = new ModelMap();
//1.获取菜单list集合
//String userId = "1";
List<SysMenu> list = new ArrayList<SysMenu>();
SysMenu sysMenu = new SysMenu();
try {
list = iSysMenuManagerBMO.querySysMenuAll(sysMenu);
} catch (Exception e) {
logger.error(e.getMessage() + "error");
}

//2.list 转成树 用的node对象集合nodeList
HashMap nodeList = new HashMap();
//根节点
Node root = null;
HashSet<Node> hashSet = new HashSet<Node>();
// 将结果集存入散列表（后面将借助散列表构造多叉树）
for (SysMenu sysmenu : list) {
Node node = new Node();
node.id = String.valueOf(sysmenu.getMenu_id());
node.name = (String) sysmenu.getMenu_name();
node.orderSeq = (String) sysmenu.getOrderSeq();
node.sysModularId = (String) sysmenu.getSysModularId();
String parentId = String.valueOf(sysmenu.getParentid());
//父节点为0 置空
if ("0".equals(parentId)) {
node.parentId = "";
} else {
node.parentId = (String) sysmenu.getParentid();
}
nodeList.put(node.id, node);
}

//3.nodeList拼装json
Set entrySet = nodeList.entrySet();
for (Iterator it = entrySet.iterator(); it.hasNext();) {
Node node = (Node) ((Map.Entry) it.next()).getValue();
if (node.parentId == null || node.parentId.equals("")) {
root = node;
} else {
((Node) nodeList.get(node.parentId)).addChild(node);
}
if (null != root) {
hashSet.add(root);
}
}

//4.对多叉树进行横向排序
root.sortChildren();

//5.输出有序的树形菜单的JSON字符串   替换其中submenu 为  children
String jsonString = String.valueOf(hashSet.toString());
String returnString = jsonString.replaceAll("submenu", "children");
logger.debug("输出的菜单为:" + returnString);
model.addAttribute("returnString", returnString);
return new ModelAndView("protected/sysMenu/sysMenuManager", model);
}

每次打开新的tab页需要创建心的iframe，并且用一个数组titleArray来保存所有创建的tab的Id,创建的每个tab的sourcemenu属性就是左侧菜单的ID。

点击左侧菜单调用openMenu(this)方法，在主界面newIndex.jsp创建新的iframe标签。

每次tab页的切换可以通过隐藏显示该tab对应的iframe,进行hide.show操作。

三:iframe a 下的js如何访问iframe b页面的dom元素

谷歌下本人测试
$("#[b]tbody",document.frames('iframename').document)这种方式无效，所以可以采取折中方式，先取父页面中id=container标签，该标签包含所有iframe，然后取contents,再去找ID=tbody元素。

[/b]

var $tbody = $("#container",parent.document).find("iframe[name=" + returnIframeContentName +"]").contents().find("#tbody");



附带：iframe不跨域，iframe跨域访问更加复杂不允许。
