這期內容當中小編將會給大家帶來有關通過在PH中使用ajax怎么實現一個流程管理系統，文章內容豐富且以專業的角度為大家分析和敘述，閱讀完這篇文章希望大家可以有所收獲。
首先要先有一個新建流程的頁面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">

<title>新建</title>
<script src="../FENGZHUANG/jquery-3.1.1.min.js"></script>
</head>
<body>
<h2>新建流程</h2>
<div>
請選擇節點人員：
<select id="user">
<?php
session_start();//需要將一些數據暫時存在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]}'>{$v[2]}</option>";
}
?>
</select>
<input type="button" value="添加節點" id="add" />
</div>
<br />
<div>
<?php
if(!empty($_SESSION["user"]))
{
$attr = $_SESSION["user"];
foreach($attr as $k=>$v) //索引為$k,取值為$v
{
$sname = "select name from users where uid='{$v}'"; //取出名稱
$name = $db->StrQuery($sname);
echo "<div>{$k}--{$name}--<input type='button' value='刪除' key='{$k}' class='del' /></div>"; //向處理頁面傳的是key的值
}
}
?>
</div>
<br />
<div>請輸入流程名稱：<input type="text" id="name" /></div>
<br />
<input type="button" value="保存" id="btn" />
</body>
<script type="text/javascript">
//添加節點按鈕加點擊
$("#add").click(function(){
var uid = $("#user").val();
$.ajax({
url:"chuli.php",
data:{uid:uid,type:0}, //傳入一個type參數，以確保在同一頁面處理時與其它的分開處理
type:"POST",
dataType:"TEXT",
success: function(data){
window.location.href="xinjian.php" rel="external nofollow" rel="external nofollow" ; //刷新頁面
}
});
})
//給刪除按鈕加點擊
$(".del").click(function(){
var key = $(this).attr("key"); //取刪除的是哪條數據
$.ajax({
url:"chuli.php",
data:{key:key,type:1},
type:"POST",
dataType:"TEXT",
success:function(data){
window.location.href="xinjian.php" rel="external nofollow" rel="external nofollow" ;
}
});
})
//給保存按鈕加點擊
$("#btn").click(function(){
var name = $("#name").val(); //取輸入框中輸入內容的值
$.ajax({
url:"chuli.php",
data:{name:name,type:2},
type:"POST",
dataType:"TEXT",
success:function(data){
alert("保存成功！");
}
});
})
</script>

處理頁面chuli.php

break;
case 1://取節點的索引，然后刪除，重新索引
$key = $_POST["key"];
$arr = $_SESSION["user"];
unset($arr[$key]); //刪除
$arr = array_values($arr); //重新索引
$_SESSION["user"] = $arr;
break;
case 2:
$name = $_POST["name"];
$code = time();
//添加流程
$sql = "insert into liucheng values('{$code}','{$name}')";
$db->Query($sql,0);
//添加流程節點
