Ajax表单提交实例
昨天在CSDN逛的时候,看见一位网友需要解决一些关于AJAX的FORM提交的问题,现在把一个实例贴出来,希望对广大爱好者有帮助.
<!--注册模块-->default.asp
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> //请一定要将此页的编码设为UTF-8,否则将出现乱码

#Layer1 {

</style>
</head>
<body>
<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 />
为突出显示无刷新效果,服务器端程序将自动进行百万加法运算
</h2>
</body>
</html>
<!----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+'®password='+GE('regpassword').value+'&file='+GE('f').value
X.send(SendData)
}
else{
GE('msg').innerHTML='你的浏览器不支持XMLHttpRequest'
}
}
<!---程序处理--->reg.asp
<%@ 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
%>
如有其他疑问,请跟帖~
这个实例本人认为比较全面,是我用AJAX表单提交的初学实例,相当够用!如有错误,请指正!谢谢!
