1.选项卡      

查找Layui的选项卡界面布局代码，复制该代码粘贴到开发工具中

 

      2. 动态的添加选项卡

添加点击事件:

 代码;

let $,element;
layui.use(['jquery','element'],function(){
	 $ = layui.jquery,element=layui.element;
	$.ajax({
		url:'${pageContext.request.contextPath}/permission.action?methodName=menus'
		,dataType:'json'
		,success:function(data){
			let htmlstr = '';
			$.each(data,function(i,n){
				htmlstr += ' 
';
				htmlstr += '   '+data[i].text+'';
				//判断一级节点是否存在子节点
				if(data[i].hasChildren){
					htmlstr += '
';
					let children = data[i].children;
					$.each(children,function(index,node){
						htmlstr += '
'+children[index].text+'
';
					});
					htmlstr += '
';
				}
				htmlstr += '
';
			});
			$("#menu").html(htmlstr);
		}
	})
}) 

效果：

function openTabs(title,url,id){
	let $node = $("li[lay-id='"+id+"']");
//	alert(title+"hkjdjhasj"+url+"adsa"+id);
	//新增一个tab项
 	 element.tabAdd('demo', {
 		title:'新选项'+(Math.random()*1000|0),//用于演示
 		content:'内容'+(Math.random()*1000|0),
		id:new Date().getTime()//实际使用一般是规定好的id，这里以时间戳模拟下
 	}) 
     
}

      3.  将选项卡名称换成菜单名

 代码：

htmlstr +='
'+children[index].text+'
';

    4.    重复的tab选项卡不添加，改为选中

 function openTabs(title,url,id){
		let $node = $("li[lay-id='"+id+"']");
		if($node.length == 0){
			 // 新增一个Tab项
		     element.tabAdd('demo', {
				title : title,//用于演示
				content : "",
				id : id
		     }) 
		}
		//切换到指定选项卡
	     element.tabChange('demo', id);
	}

       5. 跳转界面

user:

package com.zking.entity;
/**
 * 
 * @author Administrator
 *
 */

public class User {
	private Long id;
	private String name;
	private String loginName;
	private String pwd;
	private Long rid;
	public Long getId() {
		return id;
	}
	public void setId(Long id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getLoginName() {
		return loginName;
	}
	public void setLoginName(String loginName) {
		this.loginName = loginName;
	}
	public String getPwd() {
		return pwd;
	}
	public void setPwd(String pwd) {
		this.pwd = pwd;
	}
	public Long getRid() {
		return rid;
	}
	public void setRid(Long rid) {
		this.rid = rid;
	}
	public User() {
		// TODO Auto-generated constructor stub
	}
	public User(Long id, String name, String loginName, String pwd, Long rid) {
		super();
		this.id = id;
		this.name = name;
		this.loginName = loginName;
		this.pwd = pwd;
		this.rid = rid;
	}
	@Override
	public String toString() {
		return "User [id=" + id + ", name=" + name + ", loginName=" + loginName + ", pwd=" + pwd + ", rid=" + rid + "]";
	}
	
}

userDao:

package com.zking.dao;
 
import java.util.List;
 
import com.zking.entity.User;
import com.zking.util.BaseDao;
 
public class UserDao extends BaseDao{
	public User login(User user) throws Exception {
 
		String sql = "select * from t_oa_user where loginName = '"+user.getLoginName()+"' and pwd = '"+user.getPwd()+"'";
		List users = super.executeQuery(sql, User.class,null);
		//根据sql查询符合条件的用户，通常只会返回一条数据
		return users == null || users.size() ==0 ? null : users.get(0);
		//return super.executeQuery(sql, clz, pageBean);
	}
}

userAction:

package com.zking.web;

import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.zking.dao.UserDao;
import com.zking.entity.User;
import com.zking.framework.ActionSupport;
import com.zking.framework.ModelDriver;
import com.zking.util.R;
import com.zking.util.ResponseUtil;

public class UserAction extends ActionSupport implements ModelDriver{
	private User user = new User();
	private UserDao userDao = new UserDao();

	@Override
	public User getModel() {
		
		return user;
	}
	
	
	
	
	
	public String login (HttpServletRequest req, HttpServletResponse resp) {

		try {
			User u = userDao.login(user);
			//通过账户名查到了用户记录
		if(u!=null) {
			
			//ResponseUtil.writeJson(resp, new R().data("code", 200).data("msg", "成功"));
		ResponseUtil.writeJson(resp, R.ok(200,"登陆成功"));
		}
		
		else {
			//ResponseUtil.writeJson(resp, new R().data("code", 0).data("msg", "账户或密码错误"));
			ResponseUtil.writeJson(resp, R.ok(0,"用户名或密码错误"));
		}
		} catch (Exception e) {
			e.printStackTrace();
			try {
				ResponseUtil.writeJson(resp, R.ok(0,"用户名或密码错误"));
			} catch (Exception e1) {
				// TODO Auto-generated catch block
				e1.printStackTrace();
			}

		}
		return null;
	}

	

}

把界面上的代码封装到js里面;

运行结果：

 数据库所有的账号和密码

 

 登陆成功进入主界面：

 上面404没有关系，后期还要继续优化的。
