php的ajax框架xajax入门与试用
3、inc/singup.php
| 以下为引用的内容：
<?php
define ('XAJAX_DEFAULT_CHAR_ENCODING', 'gb2312' );
//注意这里，必须要设置gb2312，不然中文会乱码
require_once("xajax.inc.php");
require_once("function.php");
$xajax = new xajax();
$xajax->registerFunction("processForm");
//同reg.php文件
function processForm($aFormValues)
{
$objResponse = new xajaxResponse();
require_once("conn.php");
$usr=$aFormValues['usr'];
$email=$aFormValues['email'];
$pwd=$aFormValues['pwd'];
$pw=Md5($pwd);
$errmsg="";
//要过滤的非法字符
$ArrFiltrate=array("'",";","union");
foreach($aFormValues as $key=>$value){
if (FunStringExist($value,$ArrFiltrate)){
$objResponse->addAlert("输入的信息含有非法字符\"' ; union!\"");
$objResponse->addAssign("submitButton","value","继续");
$objResponse->addAssign("submitButton","disabled",false);
return $objResponse;
}
}
if (trim($usr) == "")
{
$errmsg.="请输入用户名!\n";
}
if (trim($pwd) == "")
{
$errmsg.="请输入密码!\n";
}
if ($pwd != $aFormValues['pwd2'])
{
$errmsg.="两次输入的密码不一致!\n";
}
if (!CheckEmailAddr($email))
{
$errmsg.="邮件地址不正确!\n";
}
$sql="select * from zl_usr where zl_usr='$usr'";
$result=mysql_query($sql,$db);
if($myrow=mysql_fetch_array($result)){
$errmsg.="用户名已经存在!\n";
}
if ($errmsg=="")
{
$sForm = "注册成功<br>用户名:".$usr."<br>email:".$email."";
$sql="insert into zl_usr(zl_usr,zl_pwd,email) values('$usr','$pw','$email')";
$result=mysql_query($sql,$db);
$objResponse->addAssign("formDiv","innerHTML",$sForm);
}
else
{
$objResponse->addAlert($errmsg);
//弹出错误信息
$objResponse->addAssign("submitButton","value","继续");
//修改submitButton的value为继续
$objResponse->addAssign("submitButton","disabled",false);
//修改submitButton这个按扭的属性
}
return $objResponse;
}
$xajax->processRequests();
?>
|
这个文件中对信息进行了有效性判断，包括：用户名是否已经注册过、信息中是否有非法字符、邮件地址是否正确、两次输入的密码是否一致，如果没有错误则输入到数据库中，并
$objResponse->addAssign("formDiv","innerHTML",$sForm);
在formDiv中重新插入代码，内容为$sForm
$sForm = "注册成功<br>用户名:".$usr."<br>email:".$email."";
如果有错误信息则
$objResponse->addAlert($errmsg);
//弹出错误信息
$objResponse->addAssign("submitButton","value","继续");
$objResponse->addAssign("submitButton","disabled",false);
//修改submitButton这个按扭的属性
3、login.php 登陆文件
| 以下为引用的内容：
<?php
require_once("inc/xajax.inc.php");
$xajax = new xajax("inc/login.php");
$xajax->registerFunction("processForm");
?>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<link rel="stylesheet" href="https://blogbeta.blueidea.com/css/style.css" _fcksavedurl=""https://blogbeta.blueidea.com/css/style.css"" type="text/css">
<title>无标题文档</title>
<?php $xajax->printJavascrīpt('inc/'); ?>
<scrīpt type="text/javascrīpt">
function submitSignup()
{
xajax.$('submitButton').disabled=true;
xajax.$('submitButton').value="https://blogbeta.blueidea.com/wait...";
xajax_processForm(xajax.getFormValues("signupForm"));
return false;
}
</scrīpt>
</head>
<body><form id="signupForm" action="javascrīpt:void(null);" ōnSubmit="submitSignup();">
<div id="main">
