昨天看見一位網友需要解決一些關于AJAX的FORM提交的問題,現在把一個實例貼出來,希望對廣大愛好者有幫助。
<!--注冊模塊-->default.asp

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> //請一定要將此頁的編碼設為UTF-8,否則將出現亂碼

<h2>Ajax應用實例: 注冊模塊</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="注冊" onclick="Check()" />
<h2>當注冊ID為 tony的用戶時,后臺驗證該ID已存在,返回提示信息<br />
為突出顯示無刷新效果,服務器端程序將自動進行百萬加法運算
</h2>
</body>
</html>
<!----表單數據提交腳本--->REG.JS
function GE(a){return document.getElementById(a);}
function Check(){
if(GE('regid').value==''){GE('msg').innerHTML='ID不能為空';return false}
if(GE('regpassword').value==''){GE('msg').innerHTML='password 不能為空';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="正在提交數據..."}
};
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='你的瀏覽器不支持XMLHttpRequest'
}
}
<!---程序處理--->reg.asp
<%@ LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>//CODEPAGE必須為650001,否則也出現亂碼,如果有HTML文字,一定設為UTF-8編碼,否則將出現亂碼.
<%
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必須填寫"
Else
If regid <> "tony" Then
str = "注冊成功,ID為" & regid & " , 密碼為" & regpassword&f
Else
str = "注冊失敗,ID已經存在"
End If
End if
Response.Write "GE('msg').innerHTML='" & str & "';GE('regsubmit').disabled=false"
Response.End
%>
這個實例本人認為比較全面,是我用AJAX表單提交的初學實例,相當夠用!如有錯誤,請指正!謝謝!
