--  Notice of meeting  （4 It is the meeting to be held ）
select
	IFNULL(f.result,-1) result,t1.*
from(
select * from t_oa_meeting_info where FIND_IN_SET(2,CONCAT(
canyuze,',',liexize,',',zhuchiren)) and state = 4
) t1
left join t_oa_meeting_feedback f on t1.id = f.meetingId
and f.personId = 2
ORDER BY result;

1.2 Feedback details SQL

According to the requirements, we can analyze and realize this step by step SQL：

-- Meeting feedback details
-- 1、 meeting id by 12 Conference , Names of all participants
           -- 1.1 First get all the participants id
           select CONCAT(canyuze,',',liexize,',',zhuchiren) from
           t_oa_meeting_info where id = 12
           -- 1.2 Then get the names of all participants
           select * from t_oa_user where FIND_IN_SET(id,(select CONCAT(canyuze,',',liexize,',',zhuchiren) from t_oa_meeting_info where id = 12))

-- 2、 Link feedback form , Get the corresponding feedback ( unread 、 To participate in 、 Do not participate )

 -- 2、 Link feedback form , Get the corresponding feedback ( unread 、 To participate in 、 Do not participate )
select
t1.`name`,IFNULL(f.result,-1) result
from(
select * from t_oa_user where FIND_IN_SET(id,(select CONCAT(canyuze,',',liexize,',',zhuchiren) from t_oa_meeting_info where id = 12))
) t1
left join t_oa_meeting_feedback f on t1.id = f.personId and f.meetingId = 12

-- 3、 Group according to the feedback ( Final feedback details SQL)

-- 3、 Group according to the feedback ( Final feedback details SQL)
select
t.result,GROUP_CONCAT(t.name) names
from(
	select
	t1.`name`,IFNULL(f.result,-1) result
	from(
	select * from t_oa_user where FIND_IN_SET(id,(select CONCAT(canyuze,',',liexize,',',zhuchiren) from t_oa_meeting_info where id = 12))
	) t1
	left join t_oa_meeting_feedback f on t1.id = f.personId and f.meetingId = 12
) t
GROUP BY t.result

Two 、 The foreground code of the meeting notice

2.1 Notice of meeting jsp file

The foreground code of the meeting notice ：meetingNotify.jsp

2.2 To encapsulate js file

Let's package the corresponding js file ：meetingNotify.js

let layer,table,$,form,test;
var row;
layui.use(['layer','table','jquery','form','test'],function(){
	layer=layui.layer,
	table=layui.table,

});

// Initialize the data table （ My approval ）
function initTable(){
	table.render({          // Perform rendering 
        elem: '#tb',   // Specify the original table element selector （ recommend id Selectors ）

                    else
                    	return "<img width='120px' src='"+d.seatPic+"'/>";
                }
            },*/

                    else
                    	return " unread ";
                }
            },
            {field: '', title: ' operation ', width: 200,toolbar:'#tbar'},
        ]]
   });
}

// Click to query 
function query(){
	table.reload('tb', {
        url: $("#ctx").val()+'/feedBack.action',     // Request address 
        method: 'POST',                    // Request mode ,GET perhaps POST

        	'methodName':'queryMeetingFeedBackByUserId',
        	'personId':$('#personId').val(),
        	'title':$('#title').val(),
        },  
        request: {                         // Custom paging request parameter name 
            pageName: 'page', // Parameter name of page number , Default ：page
            limitName: 'rows' // Parameter name of data volume per page , Default ：limit
        },
        done: function (res, curr, count) {
        	console.log(res);
        }
   });

	table.on('tool(tb)', function(obj){ // notes ：tool  Is the toolbar event name ,test  yes  table  Properties of the original container  lay-filter=" Corresponding value "
	  row = obj.data; // Get current row data

	  var tr = obj.tr; // Get the current line  tr  Of  DOM  object （ If any ）
	  console.log(row);
	  if(layEvent === 'edit'){ // Whether to attend the meeting 
		 openLayer(row.id);
	  } else {
		  
	  }
	});
}


function openLayer(id){
    layer.open({
        type: 2,                    //layer Provides 5 Layer type . The values that can be passed in are ：0（ Message box , Default ）1（ Page layer ）2（iframe layer ）3（ Loading layer ）4（tips layer ）
        title: ' Meeting feedback ',                   // Dialog title 
        area: ['660px', '400px'],   // Wide and high 
        skin: 'layui-layer-rim',    // Style class name 
        content: 'jsp/meeting/addFeedBack.jsp?id='+id,                // Pop up content . You can pass in ordinary html Content , You can also specify DOM, With more type Different but different 
        btn:[' Meeting feedback ',' close '],
        yes:function(index,layero){
        	//layer.msg(' preservation ');
        	// Call the getData Method , Get sub pages quickly form The form data 
            let data= $(layero).find("iframe")[0].contentWindow.getData();
            addMeetingFeedBack(data);
        },
        btn2:function(){
        	layer.closeAll();
        }
    });
}

//  Notice of the meeting   Participation / Feedback from not attending the meeting 
function addMeetingFeedBack(params){
	params['methodName']="add";
	console.log(params);
	$.post($("#ctx").val()+'/feedBack.action',params,function(rs){
		if(rs.success){
			layer.closeAll();
			query();
		}else{
			layer.msg(rs.msg,{icon:5},function(){});
		}
	},'json');
}

Here we are js The file uses a LayUI Expansion modules , So we also need to import our expansion file ：

test.js

// Tips ： Modules can also rely on other modules , Such as ：layui.define('layer', callback);
layui.define(function(exports){ 
  var obj = {
     hello: function(str){
        alert('Hello '+ (str||'test'));
     },
     toDate:function(date,pattern){
    	 return fmtDate(date,pattern);
     }
  };
 
  // Output test Interface 
  //test.hello('zs');
  exports('test', obj);
}); 


// to Date Class adds a new instance method format
Date.prototype.format = function (fmt) {
	//debugger;
    var o = {
        "M+": this.getMonth() + 1,                 // month 
        "d+": this.getDate(),                    // Japan 
        "h+": this.getHours(),                   // Hours 
        "m+": this.getMinutes(),                 // branch 
        "s+": this.getSeconds(),                 // second 
        "q+": Math.floor((this.getMonth() + 3) / 3), // quarter 
        "S": this.getMilliseconds()             // millisecond 
    };
    if (/(y+)/.test(fmt))
        fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
    for (var k in o)
        if (new RegExp("(" + k + ")").test(fmt))
            fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
    return fmt;
};

function fmtDate(date, pattern) {
	var ts = date.getTime();
    var d = new Date(ts).format("yyyy-MM-dd hh:mm:ss");
    if (pattern) {
        d = new Date(ts).format(pattern);
    }
    return d.toLocaleString();
};

And its corresponding configuration file ：config.js

layui.config({
  base: 'static/js/layui/modules/' // Suppose this is test.js directory 
}).extend({ // Set the module alias 
  test: 'test' // If test.js It's in the root directory , You can also do without setting an alias 
});

next , We also need to put this of ours LayUI Expand the configuration file of the module ,

Introduce to our public page ：header.jsp , In this way, we can access our configuration file all the way .

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>

<!--  introduce  layui.css -->
<link rel="stylesheet" href="${pageContext.request.contextPath }/static/js/layui/css/layui.css">
 
<!--  introduce  layui.js -->
<script src="${pageContext.request.contextPath }/static/js/layui/layui.js"></script>

<!--  Specify the root path of the entire project  -->
<base href="${pageContext.request.contextPath }/" />

<!--  Hidden field transfer value  -->
<input id="ctx" value="${pageContext.request.contextPath }" type="hidden"/>

<!--  introduce LayUI Expand the configuration file of the module  -->
<script src="${pageContext.request.contextPath }/static/js/layui/config.js"></script>

<title> Yuyuan studio </title>

When we are ready to use SQL Statement and the front page , We can start to write the background code of our meeting notification function ~

3、 ... and 、 Background code of meeting notification query

2.1 Entity class of meeting details

MeetingFeedBack：

package com.leaf.entity;

import java.io.Serializable;

/**
 *  Meeting details 
 * @author Leaf
 *
 * 2022 year 7 month 28 Japan   In the morning 11:33:21
 */
public class MeetingFeedBack implements Serializable {

	private String id;
	private Long meetingId;
	private Integer personType;
	private Long personId;
	private Integer result;
	private String reason;

	// The title of the meeting 
	private String title;

	public String getTitle() {
		return title;
	}

	public void setTitle(String title) {
		this.title = title;
	}

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public Long getMeetingId() {
		return meetingId;
	}

	public void setMeetingId(Long meetingId) {
		this.meetingId = meetingId;
	}

	public Integer getPersonType() {
		return personType;
	}

	public void setPersonType(Integer personType) {
		this.personType = personType;
	}

	public Long getPersonId() {
		return personId;
	}

	public void setPersonId(Long personId) {
		this.personId = personId;
	}

	public Integer getResult() {
		return result;
	}

	public void setResult(Integer result) {
		this.result = result;
	}

	public String getReason() {
		return reason;
	}

	public void setReason(String reason) {
		this.reason = reason;
	}

	public MeetingFeedBack() {
		super();
	}

	@Override
	public String toString() {
		return "MeetingFeedBack [id=" + id + ", meetingId=" + meetingId + ", personType=" + personType + ", personId="
				+ personId + ", result=" + result + ", reason=" + reason + "]";
	}

}

2.2 Dao Method

MeetingFeedBackDao：

package com.leaf.dao;

import java.sql.SQLException;
import java.util.List;
import java.util.Map;

import com.leaf.entity.MeetingFeedBack;
import com.leaf.entity.MeetingInfo;
import com.leaf.util.BaseDao;
import com.leaf.util.PageBean;
import com.leaf.util.StringUtils;

public class MeetingFeedBackDao extends BaseDao<MeetingFeedBack> {
	
	// Meeting notice query 
	public List<Map<String, Object>> queryMeetingFeedBackByUserId(MeetingFeedBack back, PageBean pageBean)
			throws SQLException, InstantiationException, IllegalAccessException {
		//SQL
		String sql = "select\r\n" + 
				"	IFNULL(f.result,-1) result,t1.*\r\n" + 
				" from(\r\n" + 
				" select * from t_oa_meeting_info where FIND_IN_SET("+back.getPersonId()+",CONCAT(\r\n" + 
				" canyuze,',',liexize,',',zhuchiren)) and state = 4\r\n" + 
				" ) t1\r\n" + 
				" left join t_oa_meeting_feedback f on t1.id = f.meetingId\r\n" + 
				" and f.personId = "+back.getPersonId()+"\r\n" + 
				" ORDER BY result";
		return super.executeQuery(sql, pageBean);
	}
	
}

2.3 Action layer ：

MeetingFeedBackAction ：

package com.leaf.web;

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

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

import com.leaf.dao.MeetingFeedBackDao;
import com.leaf.entity.MeetingFeedBack;
import com.leaf.mvc.ActionSupport;
import com.leaf.mvc.ModelDriven;
import com.leaf.util.PageBean;
import com.leaf.util.R;
import com.leaf.util.ResponseUtil;

public class MeetingFeedBackAction extends ActionSupport implements ModelDriven<MeetingFeedBack> {

	private MeetingFeedBack Back = new MeetingFeedBack();
	private MeetingFeedBackDao backDao = new MeetingFeedBackDao();
	
	@Override
	public MeetingFeedBack getModel() {
		return Back;
	}
	
	// Meeting notice query 
	public String queryMeetingFeedBackByUserId(HttpServletRequest req, HttpServletResponse resp) {
		try {
			PageBean pageBean = new PageBean();
			// initialization 
			pageBean.setRequest(req);
			List<Map<String, Object>> list = backDao.queryMeetingFeedBackByUserId(Back, pageBean);
			ResponseUtil.writeJson(resp, R.ok(0, " Meeting notification data query succeeded " ,pageBean.getTotal() ,list));
		} catch (Exception e) {
			e.printStackTrace();
			try {
				ResponseUtil.writeJson(resp, R.ok(0, " Meeting notification data query failed "));
			} catch (Exception e1) {
				e1.printStackTrace();
			}
		}
		return null;
	}
	
}

2.4 To configure xml file

<?xml version="1.0" encoding="UTF-8"?>

<config>
	
	<action path="/user" type="com.leaf.web.UserAction">
	</action>
	
	<action path="/permission" type="com.leaf.web.PermissionAction">
	</action>
	
	<action path="/permissionTo" type="com.leaf.web.PermissionToAction">
	</action>
	
	<action path="/info" type="com.leaf.web.MeetingInfoAction">
	</action>
	
	<action path="/audit" type="com.leaf.web.MeetingAuditAction">
	</action>
	
	<action path="/feedBack" type="com.leaf.web.MeetingFeedBackAction">
	</action>
	
</config>

Test the query ：

After testing , We see that the query has been successful , In this way, the meeting notice inquiry is done ！
Then we can start to do the meeting feedback function , Feedback whether users participate in the meeting .

Four 、 Meeting feedback function

4.1 Packaging related js file

Let's first put the front-end code of the meeting feedback ：addFeedBack.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@include file="/common/header.jsp"%>
<!DOCTYPE html>
<!--  Feedback on whether to attend the meeting  -->
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="static/js/meeting/addFeedBack.js"></script>
</head>
<style>
body{
	margin:5px;
}
</style>
<body>
<div style="padding:10px;">
    <form class="layui-form layui-form-pane" lay-filter="back">
    	<!-- <div class="layui-form-item">
		    <button type="submit" class="layui-btn" lay-submit="" lay-filter="meeting"> Submit... Immediately </button>
		    <button id="reset" type="reset" class="layui-btn layui-btn-primary"> Reset </button>
  		</div> -->
  		<input type="hidden" name="meetingId" value="${param.id }"/>
  		<input type="hidden" name="personId" value="${sessionScope.user.id }"/>
         <div class="layui-form-item">
            <label class="layui-form-label"> The type of people </label>
            <div class="layui-input-block">
                <select id="personType" name="personType">
                <option value=""> Please select the personnel type </option>
                <option value="1"> Participation </option>
                <option value="2"> Attend as nonvoting delegates </option>
			</select>
            </div>
        </div>
        <div class="layui-form-item">
            <label class="layui-form-label"> Feedback results </label>
            <div class="layui-input-block">
                <select id="result" name="result">
                <option value=""> Please select the feedback result </option>
                <option value="1"> To participate in </option>
                <option value="2"> Do not participate </option>
			</select>
            </div>
        </div>
        <div class="layui-form-item layui-form-text">
		    <label class="layui-form-label"> Reasons for not participating in the meeting </label>
		    <div class="layui-input-block">
		      <textarea placeholder=" Please enter the content " name="reason" class="layui-textarea"></textarea>
		    </div>
		</div>
    </form>
</div>
</body>
</html>

Then package the corresponding js file ：addFeedBack.js

let form,$;
layui.use(['form','jquery'],function(){
	form=layui.form,
	$=layui.jquery;
});


function getData(){
	return form.val('back');
}

4.2 Dao Method

Let's continue to write above Dao Inside the layer ：

	// Meeting feedback （ Whether to attend the meeting ）
	public int add(MeetingFeedBack back) throws Exception {
		String sql = "insert into t_oa_meeting_feedback values(?,?,?,?,?,?)";
		back.setId(UUID.randomUUID().toString().replaceAll("-", ""));
		return super.executeUpdate(sql, back, new String[] {"id","meetingId","personType","personId","result","reason"});
	}

4.3 Action layer

// Meeting feedback （ Whether to attend the meeting ）
	public String add(HttpServletRequest req, HttpServletResponse resp) {
		try {
			//rs yes SQL Number of lines affected by statement execution 
			int rs = backDao.add(Back);
			// Judge 
			if(rs > 0) {
				ResponseUtil.writeJson(resp, R.ok(200, " The feedback from the meeting was successful "));
			}
			else {
				ResponseUtil.writeJson(resp, R.ok(0, " Meeting feedback failed "));
			}
		} catch (Exception e) {
			e.printStackTrace();
			try {
				ResponseUtil.writeJson(resp, R.ok(0, " Meeting feedback failed "));
			} catch (Exception e1) {
				e1.printStackTrace();
			}
		}
		return null;
	}

Then we test the feedback ：

The test results , The meeting feedback was also successfully completed ！

5、 ... and 、 Feedback details

5.1 encapsulation js Code

myMeeting.js

	let layer,table,$,form;
	var row;
	layui.use(['layer','table','jquery','form'],function(){
		layer=layui.layer,
		table=layui.table,
		form=layui.form,
		$=layui.jquery;
		
		initTable();
		
		// Query events 
		$('#btn_search').click(function(){
			query();

Here we are test to glance at ：

First feedback a result ：

Then log in to the account of the meeting publisher , Query feedback details ：

We can see , The feedback details function is also realized ~

OK, today Leaf Bring the meeting OA Project meeting notice and feedback && That's all for the feedback details function , There are more function code sharing in the later stage , Welcome to study together , I'll see you next time ！！！
