后台使用php,前台引用jquery,实现增删操作,代码如下:
代码如下:
<script type="text/javascript" src="jquery-1.10.2.min.js"></script> <?php header("Content-type: text/html; charset=utf-8"); //mysql_connect 建立连接,mysql_close($link)关闭非永久连接,mysql_pconnect 建立永久连接 //mysql_error返回mysql函数错误信息,mysql_errno返回mysql函数错误号码 //mysql_set_charset 设置用户端字符集,mysql_select_db 选择连接数据库 //mysql_query 执行查询,mysql_num_rows返回查询记录条数 //mysql_affected_rows返回受影响的记录条数,mysql_free_result 释放结果集内存 //mysql_fetch_row 返回列举阵列记录,mysql_fetch_assoc 返回关联阵列记录 //mysql_fetch_array 返回关联阵列或数字阵列记录,mysql_fetch_object 返回物件形式记录 //mysql_fetch_result 取得结果集资料 //%s 字符串,%c 一个ASCII字符,%d 一个整数,%u 一个符号数,%x 一个十六进制数 mysql_query("set charaset set utf-8"); $message=@$_POST["message"]; $shanchu=@$_POST["shanchu"]; $top_title="PHP基础练习"; $con=mysql_connect("localhost","root",""); //连接数据库 mysql_set_charset('utf-8',$con); mysql_select_db("dbl",$con); //定义数据库命令查询 $sql="select `message` ,`time`,`id` from message order by id desc limit 0,30"; //执行数据库查询 $rs=mysql_query($sql,$con); $time=date('Y-m-d h:i:s',time()); //获取条数 $num_rows=mysql_num_rows($rs);//mysql_num_rows返回查询记录条数 if (isset($_POST["submits"])) { if(!$_POST["message"]==null){ $queryinsert=sprintf("insert into message (message,time) values('%s','%s')", $_POST['message'],$time); mysql_query($queryinsert,$con); } if($_POST["message"]==null){ echo ""; } header("Location:http://localhost/table.php"); } if(isset($_GET["ClearTd"]) && intval($_GET['ClearTd'])){ $querydelete="delete from message where id=".$_GET['ClearTd']; mysql_query($querydelete,$con); header("Location:http://localhost/table.php"); } ?> <form method="post" action="table.php"> <textarea name="message" id="message"></textarea> <input type="submit" name="submits"> </form> <ul> <?php while($row=mysql_fetch_array($rs,MYSQL_ASSOC)) { ?> <li> <?php foreach($row as $tiao){ echo $tiao; }?> <a name="ClearTd" href="?ClearTd=<?php echo $row['id'];?>">删除</a> </li> <?php } ?> </ul>
