<h2>Ajax应用实例: 注册模块</h2> 
<div id="Layer1"> 
<div id="msg"></div> 
</div> 
ID: <input type="text" id="regid" /> 
Password: <input type="password" id="regpassword" /> 
<input name="f" type="file" /> 
<input type="submit" id="regsubmit" value="注册" onclick="Check()" /> 
<h2>当注册ID为 tony的用户时,后台验证该ID已存在,返回提示信息<br />

复制代码代码如下:

<!----表单数据提交脚本--->REG.JS 
function GE(a){return document.getElementById(a);} 
function Check(){ 
if(GE('regid').value==''){GE('msg').innerHTML='ID不能为空';return false} 
if(GE('regpassword').value==''){GE('msg').innerHTML='password 不能为空';return false} 
var X=new ActiveXObject("Msxml2.XMLHTTP"); 
if(X){ 
GE('regsubmit').disabled=true; 
X.onreadystatechange=function(){ 
if(X.readyState==4){ 
if(X.status==200){ 
eval(X.responseText) 
} 
else{GE('msg').innerHTML=X.statusText} 
} 
else{GE('msg').innerHTML="正在提交数据..."} 
}; 
X.open('POST','reg.asp',true); 
X.setRequestHeader('Content-Type','application/x-www-form-urlencoded'); 
var SendData = 'regid='+GE('regid').value+'&regpassword='+GE('regpassword').value+'&file='+GE('f').value 
X.send(SendData) 
} 
else{ 
GE('msg').innerHTML='你的浏览器不支持XMLHttpRequest' 
} 
} 

reg.asp

复制代码代码如下:

<%@ LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>//CODEPAGE必须为650001,否则也出现乱码,如果有HTML文字,一定设为UTF-8编码,否则将出现乱码. 
<% 
Dim regid, regpassword, str 
regid=Request.Form("regid") 
regpassword=Request.Form("regpassword") 
f=Request.Form("file") 
Dim i, ii 
ii = 0 
For i = 0 To 1000000 
ii = ii + i 
Next 
If regid="" or regpassword="" then 
str = "ID和PASSWORD必须填写" 
Else 
If regid <> "tony" Then 
str = "注册成功,ID为" & regid & " , 密码为" & regpassword&f 
Else 
str = "注册失败,ID已经存在" 
End If 
End if 
Response.Write "GE('msg').innerHTML='" & str & "';GE('regsubmit').disabled=false" 
Response.End
