用ajax和PHP实现简单的流程管理

2018-06-22 05:13:00来源：未知阅读 ()

首先要先有一个新建流程的页面xinjian.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>新建</title>
<script src="../FENGZHUANG/jquery-3.1.1.min.js"></script>
</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();
        $.ajax({
            url:"chuli.php",
            data:{uid:uid,type:0},  //传入一个type参数，以确保在同一页面处理时与其它的分开处理
            type:"POST",
            dataType:"TEXT",
            success: function(data){
                    window.location.href="xinjian.php"; //刷新页面
                }
            });
    })
    
//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({
            url:"chuli.php",
            data:{key:key,type:1},
            type:"POST",
            dataType:"TEXT",
            success:function(data){
                window.location.href="xinjian.php";
                }
            });
    })
//给保存按钮加点击
$("#btn").click(function(){
        var name = $("#name").val();  //取输入框中输入内容的值
        $.ajax({
            url:"chuli.php",
            data:{name:name,type:2},
            type:"POST",
            dataType:"TEXT",
            success:function(data){
                    alert("保存成功！");
                }
            });
    })
</script>

处理页面chuli.php

<?php
session_start();
include("../FENGZHUANG/DBDA.class.php");
$db = new DBDA();

$type = $_POST["type"];

switch($type)

        else
