function openDialog(){ ???????$("#dialog0").dialog("open");}6.4保存方法
//保存方法function save(){ ?$("#form0").form("submit",{ ???//提交的目标服务器地址 ???url : "save.php" , ???//验证表单内元素是否有效？ ???onSubmit : function(){ ???????return $(this).form("validate"); ???} , ???//如果服务器成功返回数据，就会启动这个方法 ???//参数data就是服务器返回的数据 ???success : function(data){ ???????data = eval("("+data+")"); ???????if(data.errCode < 0){ ???????????$.messager.alert("系统提醒",data.errMsg); ???????????return; ???????} ???????$.messager.alert("系统提醒","保存成功！");$("#grid0").datagrid("reload"); ???????$("#dialog0").dialog("close"); ???} ?});}6.5保存用户后台编写
<?php
//连接MySQL数据库$conn = mysql_connect("localhost","root","");$db = mysql_select_db("test",$conn);mysql_query("set names utf8");//设置一个返回对象$resultData = array();$resultData["errCode"] = 0;$resultData["errMsg"] = "";if(isset($_POST["id"]) && $_POST["id"] != null){ ???//修改}else{ ???//新增 ???$username = $_POST["username"]; ???$password = $_POST["password"]; ???$nickname = $_POST["nickname"]; ???$sql = "insert into tm_users values (NULL,‘$username‘,‘$password‘,‘$nickname‘,now(),now(),0)"; ???mysql_query($sql) or die(err()); ???echo json_encode($resultData);}function err(){ ???$resultData["errCode"] = -1; ???$resultData["errMsg"] = mysql_error(); ???echo json_encode($resultData); ???return;}?>
6.6保存用户的时候不允许用户名重复

做一个优化，因为目前的密码虽然在页面上用 * 表示，但是只要是懂一点编程的人，都知道用浏览器的抓包工具去查看泛泰返回的数据。
其实，一劳永逸的方法，就是保存密码的时候就把你这个密码进行加密。这样一来，我们存到数据库里面的密码就已经是加密过的字符串。
方法：
$password = md5 ( $_POST["password"] );源码获取：https://www.jianshu.com/p/4977bd0073d5
