Ajax表单提交实例_html element ajax提交表单demo-优快云博客

昨天在优快云逛的时候,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.

default.asp

#Layer1 {
 position:absolute;
 width:200px;

<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>

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

<%@ 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!
