• 用ajax和PHP实现简单的流程管理


    首先要先有一个新建流程的页面xinjian.php

    </head>
    
    <body>
    <h1>新建流程</h1>
    
    <div>
    请选择节点人员:
    <select id="user">
        <?php
        session_start();//需要将一些数据暂时存在session里
        include("../FENGZHUANG/DBDA.class.php");
        $db = new DBDA();
        
        $sql = "select * from users";
        $arr = $db->Query($sql);
        foreach($arr as $v)
        {
            echo "<option value='{$v[0]}'>{$v[2]}</option>";
        }
        ?>
    </select>
    <input type="button" value="添加节点" id="add" />
    </div>
    <br />
    <div>
        <?php
        if(!empty($_SESSION["user"]))
        {
            $attr = $_SESSION["user"];
            foreach($attr as $k=>$v)  //索引为$k,取值为$v
            {
                $sname = "select name from users where uid='{$v}'";  //取出名称
                $name = $db->StrQuery($sname);
                echo "<div>{$k}--{$name}--<input type='button' value='删除' key='{$k}' class='del' /></div>"; //向处理页面传的是key的值
            }
        }
        ?>
    </div>
    <br />
    <div>请输入流程名称:<input type="text" id="name" /></div>
    <br />
    <input type="button" value="保存" id="btn" />
    
    
    </body>
    <script type="text/javascript">
    //添加节点按钮加点击
    $("#add").click(function(){
            var uid = $("#user").val();

        })
        
    //给删除按钮加点击
    $(".del").click(function(){
            var key = $(this).attr("key");  //取删除的是哪条数据
            $.ajax({

    //给保存按钮加点击
    $("#btn").click(function(){
