摘要: jquery菜单插件 前后源码&例子

由于后台使用了chen框架,所以代码不能完全列出,可以到http://git.oschina.net/eternal_rider/chen下载项目,运行后,即可看到菜单效果级管理。

示例框架中写了一个jquery菜单插件实现,可以使用存html代码+样式使用也可以给出json格式数据,以jquery插件方式

对应json格式,我写了示例代码,从数据库表总读取记录,转成json。sql只要select * from 表 order by 父id,即按照父编号排序,这样生成html时,先生成根节点,然后子节点,孙子节点。。。这样。我也做后台管理,可以在后台添加编辑,前台自动展现,以后会加授权功能。

先看下效果,然后在看代码。

HTML-scheme:

<ul id="menu"> <li><a href="#">chen框架介绍</a></li> <li> <a href="#">设计文档</a> <ul> <li><a href="#">视图层</a></li> <li><a href="#">控制层</a></li> <li><a href="#">模型层</a></li> <li><a href="#">仓储层</a></li> </ul> </li> <li><a href="#">示例项目</a></li> <li><a href="#">后台管理</a></li> </ul>



css样式

html方式是,使用以上css+html代码即可生成菜单。


一下为jquery插件方式:

menu.js

 (function(jQuery){ jQuery.fn.menu=function(data){ if(typeof data=="string"){ data = eval("("+data+")"); } var jQuerythis=jQuery(this); var jQuerycoldrop=jQuery(document.createElement("ul")).attr("id","menu"); var ids=jQuerythis.attr("id"); jQuerythis.append(jQuerycoldrop); for(var i=0;i<data.length;i++){ var n = data[i]; var jQueryitem=jQuery(document.createElement("li")); if(n.pid==0){ jQuerycoldrop.append(jQueryitem); jQueryitem.html("<a href=\"javascript:void(0);\" onClick=\"goUrl(\'"+n.name+"\',\'"+n.mode+"\',\'"+n.url+"\')\">"+n.name+"</a>").attr({"id":"col_"+ids+"_"+n.id}); }else{ if(jQuery("#col_"+ids+"_"+n.pid).find("ul").length<=0){ jQuery("#col_"+ids+"_"+n.pid).append("<ul></ul>"); jQuery("#col_"+ids+"_"+n.pid).find("ul:first").append(jQueryitem); jQueryitem.html("<a href=\"javascript:void(0);\" onClick=\"goUrl(\'"+n.name+"\',\'"+n.mode+"\',\'"+n.url+"\')\">"+n.name+"</a>").attr({"id":"col_"+ids+"_"+n.id}); }else{ jQuery("#col_"+ids+"_"+n.pid).find("ul:first").append(jQueryitem); jQueryitem.html("<a href=\"javascript:void(0);\" onClick=\"goUrl(\'"+n.name+"\',\'"+n.mode+"\',\'"+n.url+"\')\">"+n.name+"</a>").attr({"id":"col_"+ids+"_"+n.id}); } } } } })(jQuery); function goUrl(title,mode,iurl){ if(iurl == ""){ return; } var h = window.screen.height; var w = window.screen.width; if(mode == "modal"){ window.showModalDialog(iurl,{name:title},"dialogWidth="+w+";dialogHeight="+h+";resizable=true;location=no;toolbar=no;titlebar=no"); }else if(mode == "dialog"){ //open div }else if(mode == "_blank"){ }else{ } }

goUrl函数,可以自己修改为,任意的展现方式,如更新iframe等。

插件方式例子代码:

<!doctype html>
<html>
<head>
    <meta http-equiv="content-type" content="text/html;charset=utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <title>jquery菜单插件</title>
    <link type="text/css" href="resources/menu/menu.css" rel="stylesheet" />
    <script type="text/javascript" src="resources/jquery.min.js"></script>
    <script type="text/javascript" src="resources/menu/menu.js"></script>
    <script type="text/javascript">
    jQuery(function(){
		//jQuery("#mymenu").menu('json数组'),下面为从后台获得
    	jQuery("#mymenu").menu('${sessionScope.UserInfo.MenuJson}');
    	});
    </script>
</head>
</head>
<body>
	<div id="mymenu" class="mainMenu"></div>
</body>
</html>



上面为了jquery库布和其他库冲突我没用使用$,而是用JQuery。

json格式

[{"id":"1","icon":"","name":"chen框架介绍","pid":"0","leaf":"1","url":"pages/home.jsp","mode":"modal"},{"id":"3f076f9aa6d74220b1f86b33ffb68387","icon":null,"name":"访问日志","pid":"e50d1c568d19412ca1a97d8bdc01629d","leaf":"1","url":"","mode":"modal"},{"id":"2","icon":"","name":"设计文档","pid":"0","leaf":"0","url":"","mode":"modal"},{"id":"79fe85544ed34957a0a638899ba5709e","icon":null,"name":"模块访问日志","pid":"e50d1c568d19412ca1a97d8bdc01629d","leaf":"1","url":"","mode":"modal"},{"id":"3","icon":"","name":"视图层","pid":"2","leaf":"1","url":"","mode":"modal"},{"id":"688881325bd941dc860afd5437c212a6","icon":null,"name":"操作日志","pid":"e50d1c568d19412ca1a97d8bdc01629d","leaf":"1","url":"","mode":"modal"},{"id":"4","icon":"","name":"控制层","pid":"2","leaf":"1","url":"","mode":"modal"},{"id":"e50d1c568d19412ca1a97d8bdc01629d","icon":null,"name":"日志管理","pid":"6","leaf":"0","url":"directory","mode":"modal"},{"id":"6","icon":"","name":"后台管理","pid":"0","leaf":"0","url":"","mode":"modal"},{"id":"7","icon":"","name":"用户管理","pid":"6","leaf":"1","url":"","mode":"modal"},{"id":"8","icon":"","name":"角色管理","pid":"6","leaf":"1","url":"","mode":"modal"},{"id":"9","icon":"","name":"菜单管理","pid":"6","leaf":"1","url":"pages/manager/menu/menuManager.jsp","mode":"modal"},{"id":"10","icon":"","name":"教程分类","pid":"6","leaf":"1","url":"","mode":"modal"},{"id":"11","icon":"","name":"教程分类","pid":"10","leaf":"1","url":"","mode":"modal"},{"id":"12","icon":"","name":"教程管理","pid":"10","leaf":"1","url":"","mode":"modal"}]



{"id":"1","icon":"","name":"chen框架介绍","pid":"0","leaf":"1","url":"pages/home.jsp","mode":"modal"}

id:菜单的编号

icon:菜单图标(这个我还没有加,过几天加上)

name:菜单名称

pid:菜单的父级编号

leaf:是否为叶子节点,即是否目录(这个在后台管理中用到了,如果你不用后台管理,可以忽略)

url:菜单地址

mode:菜单展现方式,如弹出div,弹出新窗口等,具体见goUrl函数。


菜单数据库表,一般结构如下:

后台管理,java

package my.action;

import java.util.Map;

import my.model.MenuModel;
import chen.ioc.Chen;
import chen.view.Renderer;
import chen.view.TextRenderer;

public class MenuAction {
	
	public Renderer list(Map<String,Object> args){
		MenuModel mmodel = Chen.container.get(MenuModel.class);
		String jsonStr = mmodel.loadMenuById(args);
		return new TextRenderer(jsonStr);
	}
	
	public Renderer add(Map<String,Object> args){
		MenuModel mmodel = Chen.container.get(MenuModel.class);
		int n = mmodel.add(args);
		return new TextRenderer(String.valueOf(n));
	}
	
	public Renderer edit(Map<String,Object> args){
		MenuModel mmodel = Chen.container.get(MenuModel.class);
		int n = mmodel.edit(args);
		return new TextRenderer(String.valueOf(n));
	}
	
	public Renderer delete(Map<String,Object> args){
		MenuModel mmodel = Chen.container.get(MenuModel.class);
		int n = mmodel.delete(args);
		return new TextRenderer(String.valueOf(n));
	}
}



package my.model;

import java.util.List;
import java.util.Map;

import net.sf.json.JSONArray;
import chen.util.DbUtil;

public class MenuModel{
	
	public int add(Map<String,Object> args) {
		try {
			return DbUtil.dao.save(this, args);
		}catch (Exception e) {
			e.printStackTrace();
			return 0;
		}
	}
	
	public int edit(Map<String,Object> args) {
		try {
			return DbUtil.dao.update(this, args, "id=#id#");
		}catch (Exception e) {
			e.printStackTrace();
			return 0;
		}
	}
	public int delete(Map<String,Object> args) {
		try {
			return DbUtil.dao.delete(this, args, "id=#id#");
		}catch (Exception e) {
			e.printStackTrace();
			return 0;
		}
	}
	
	public String loadAllMenu(Map<String,Object> args) {
		return this.loadMenu(selectAllMenu,null);
	}
	
	public String loadMenuById(Map<String,Object> args) {
		if(args.get("id") == null){
			args.put("id","0");
		}
		return this.loadMenu(selectMenuById,args);
	}
	
	public String loadMenu(String sql,Map<String,Object> args) {
		try {
			List<Map<String, Object>> menus = null;
			if(args == null){
				menus = DbUtil.dao.query(sql);
			}else{
				menus = DbUtil.dao.query(sql,args);
			}
			return JSONArray.fromObject(menus).toString();
		} catch (Exception e) {
			e.printStackTrace();
			return null;
		}
	}
	
	
	private String selectAllMenu = "select id,pid,name,url,leaf,icon,'modal' mode from menu order by ord asc";
	private String selectMenuById = "select id,pid,name,url,leaf,icon,'modal' mode,decode(leaf,'1','','closed') state from menu where pid=#id# order by ord asc";
}

由于使用了chen框架,所以代码不能完全列出,可以到http://git.oschina.net/eternal_rider/chen下载项目,运行后,即可看到菜单效果级管理(没有完全开发完。)
