var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari

xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("error2").innerHTML="*"; //复位

<3>密码验证

Js代码

[javascript]

{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{ document.getElementById("error3").innerHTML="*";
document.getElementById("password2").value="";
document.getElementById("error4").innerHTML="*";
if(password1.length==0)
{
document.getElementById("error3").innerHTML="*密码不能为空！";

}
else
{
if(password1.length<6||password1.length>16)
{
document.getElementById("error3").innerHTML="*密码为6-16个字符！";

}
else
{
var reg=/[a-zA-Z0-9]/; //在js中使用正则表达式 www.2cto.com
if(reg.test(password1))
{
document.getElementById("error3").innerHTML="*密码可用！";
}
else
{
document.getElementById("error3").innerHTML="*密码不可用！";

}
}
}
}
}
xmlhttp.open("GET","index.php",true);
xmlhttp.send();
}
function checkPwd1(password1)
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{ document.getElementById("error3").innerHTML="*";
document.getElementById("password2").value="";
document.getElementById("error4").innerHTML="*";
if(password1.length==0)

document.getElementById("error3").innerHTML="*密码不能为空！";

}
else
{
if(password1.length<6||password1.length>16)
{
document.getElementById("error3").innerHTML="*密码为6-16个字符！";

}
else
{
var reg=/[a-zA-Z0-9]/; //在js中使用正则表达式
if(reg.test(password1))
{
document.getElementById("error3").innerHTML="*密码可用！";
}
else
{
document.getElementById("error3").innerHTML="*密码不可用！";

}
}
}
}
}
xmlhttp.open("GET","index.php",true);
xmlhttp.send();
}

<4>重复密码验证

Js代码

[javascript]
function checkPwd2(password2)
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{ document.getElementById("error4").innerHTML="*";
if(password2.length==0)
{
document.getElementById("error4").innerHTML="*请确认密码！";

}
else
{
if(password2!=document.getElementById("password1").value)
{
document.getElementById("error4").innerHTML="*两次密码输入不一致！";

}
else
{
document.getElementById("error4").innerHTML="*密码输入一致！";
}

}
}
}
xmlhttp.open("GET","index.php",true);
xmlhttp.send();
}
function checkPwd2(password2)
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{ document.getElementById("error4").innerHTML="*";
if(password2.length==0)
{
document.getElementById("error4").innerHTML="*请确认密码！";

}
else
{
if(password2!=document.getElementById("password1").value)
{
document.getElementById("error4").innerHTML="*两次密码输入不一致！";

}
else
{
document.getElementById("error4").innerHTML="*密码输入一致！";
}

}
}
}
xmlhttp.open("GET","index.php",true);
xmlhttp.send();
}

怎么样，挺简单的吧！（未完待续）
