復(fù)制代碼代碼如下:

<!----表單數(shù)據(jù)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");

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(shù)據(jù)..."} 
}; 
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='你的瀏覽器不支持XMLHttpRequest' 
} 
} 

reg.asp

復(fù)制代碼代碼如下:

<%@ LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>//CODEPAGE必須為650001,否則也出現(xiàn)亂碼,如果有HTML文字,一定設(shè)為UTF-8編碼,否則將出現(xiàn)亂碼.
