<title>注册页面</title>
<head>
<script language="javascript">
//JavaScript Document
var xmlHttp;
function S_xmlhttprequest()
{
xmlHttp=null;
if (window.XMLHttpRequest)
{// code for IE7, Firefox, Opera, etc.
xmlHttp=new XMLHttpRequest();
}
else if (window.ActiveXObject)
{// code for IE6, IE5
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");

}
function getName(name)
{
if(name = document.myform.name.value)

S_xmlhttprequest();
xmlHttp.open("get","date.php?name="+name,true);
xmlHttp.onreadystatechange = byname;
xmlHttp.send(null);

function byname()
{
if(xmlHttp.readyState ==1)
{
document.getElementById("name").innerHTML = "检测中......";

if(xmlHttp.readyState == 4)
{
if(xmlHttp.status == 200)

function getEmail(email)

else

function byemail()
{
if(xmlHttp.readyState ==1)

}
if(xmlHttp.readyState == 4)
{
if(xmlHttp.status == 200)

document.getElementById('email').innerHTML = email;
}
}
}
</script>
</head>
<body>
<form action="" method="post" name="myform">
<table align="center">
<tr><td>用户名:</td><td><input type="text" name="name" value="" onblur="getName('name')"/>
</td><td><div id="name"><font color="#CC66CC">*用户名必填*</font></div></td></tr>
<tr><td>邮箱:</td><td><input type="text" name="email" value="" onblur="getEmail('email')"/>
</td><td><div id="email"><font color="#CC66CC">*邮箱必填*</font></div></td></tr>
</table>
</form>
</body>
而这个是数据验证代码date.php
<?php
sleep(1);
$connt = mysql_connect("localhost","root","root");
mysql_select_db('people',$connt );
mysql_query("set names 'gb2312'");
if($_GET['name'])
{
$name = $_GET['name'];
$sql = "select * from tb_user where usernc='$name'";
$restul = mysql_query($sql);
$array = mysql_fetch_row($restul);
// print_r($array);
if(is_array($array))
{
echo "<font color='red'>该用户名已经存在</font>";
}
else
{
echo "<font color='red'>该用户名可以用</font>";
}
}
if($_GET['email'])
{
$name = $_GET['email'];
$sql = "select * from tb_user where email='$email'";
$restul = mysql_query($sql);
$array = mysql_fetch_row($restul);
// print_r($array);
if(is_array($array))
{
echo "<font color='red'>该邮箱已存在</font>";
}
else
{
echo "<font color='red'>该邮箱可以用</font>";
}
}
?>
希望给解决一下 |
