asp+ajax 出现乱码如何解决？

[来得查理]

index.asp

<%@LANGUAGE="VBSCRIPT.Encode" CODEPAGE="65001"%>
<%

	Db="data/test12.mdb"
    ConnStr = "Provider = Microsoft.Jet.OLEDB.4.0;Data Source = " & Server.MapPath(Db)
	On Error Resume Next
	Set Conn = Server.CreateObject("ADODB.Connection")
	Conn.Open ConnStr
	
	function getBigClass()
		dim sql
		sql = "select * from BigClass"
		set rs = server.CreateObject("adodb.Recordset")
		rs.open sql,conn,1,3
		do while not rs.eof
			BigClass= BigClass&"<option value='"&rs("BigClassId")&"'>"&rs("BigClassName")&"</option>"	
			rs.movenext
		loop
		Response.Write BigClass
	End function
%>

<script>
function sendajax(BigClassId)
{
 var ajaxObj;
 var values;
 if(window.XMLHttpRequest){
  ajaxObj = new XMLHttpRequest();
 } else if(window.ActiveXObject){
  ajaxObj = new ActiveXObject("Microsoft.XMLHTTP");
 }
 if(ajaxObj){
  //alert("创建ajax成功!");

}

 ajaxObj.open("GET","getSmallClass.asp?BigClassId="+BigClassId,true);
 ajaxObj.onreadystatechange = function(){
  if(ajaxObj.readyState==4){
   if(ajaxObj.status==200)
   {
    var txt = ajaxObj.responseText
	document.getElementById("t").innerHTML=txt;
   }
  }
 
 }
 ajaxObj.send(null);
}
</script>

<div>
<select id="BigClass" onchange="sendajax(this.options[selectedIndex].value)">
	<%
	Call getBigClass()
	%>
</select>

<select id="SmallClass">
</select>

</div>

<span id="t"></span>

getSmallClass.asp

<%@LANGUAGE="VBSCRIPT.Encode" CODEPAGE="65001"%>
<%   Db="data/test12.mdb"
    ConnStr = "Provider = Microsoft.Jet.OLEDB.4.0;Data Source = " & Server.MapPath(Db)
	On Error Resume Next
	Set Conn = Server.CreateObject("ADODB.Connection")
	Conn.Open ConnStr
	
	BigClassId = request("BigClassId")
	
	set rs = server.CreateObject("adodb.recordset")
	rs.open "select * from SmallClass where BigClassId="&BigClassId,conn,1,3
	
	do while not rs.eof
		SmallClassStr = SmallClassStr&rs("SmallClassId")&","&rs("SmallClassName")&"|"
	rs.movenext
	loop
	Response.Write SmallClassStr
	rs.close
	set rs = nothing
%>

[hookee]

试试看
getSmallClass.asp文件本身 存为 utf-8编码。 用Windows记事本打开，另存为，编码选utf-8
-----------
或者
ie的话

var txt = gb2utf8(ajaxObj.responseBody)

function gb2utf8(data){ 
   var glbEncode = []; 
   gb2utf8_data = data; 
   execScript("gb2utf8_data = MidB(gb2utf8_data, 1)", "VBScript"); 
   var t=escape(gb2utf8_data).replace(/%u/g,"").replace(/(.{2})(.{2})/g,"%$2%$1").replace(/%([A-Z].)%(.{2})/g,"@$1$2"); 
   t=t.split("@"); 
   var i=0,j=t.length,k; 
   while(++i<j) { 
      k=t[i].substring(0,4); 
      if(!glbEncode[k])  
      { 
         gb2utf8_char = eval("0x"+k); 
         execScript("gb2utf8_char = Chr(gb2utf8_char)", "VBScript"); 
         glbEncode[k]=escape(gb2utf8_char).substring(1,6); 
      } 
      t[i]=glbEncode[k]+t[i].substring(4); 
   } 
   gb2utf8_data = gb2utf8_char = null; 
   return unescape(t.join("%")); 
}

CODEPAGE="65001"?
应该是编码问题，你把编码都统一了就ok了

[xj150145223]

如果你代码里面的编码都统一，那么试着将文件 “高级保存”--“UTF-8代签名”

[sumjor]

编码没有统一吧

[lwlfree]

用URL编码传输数据，得到数据后解码即可。
至于页面上出现乱码，有可能是文件保存时所选择的编码格式与页面中声明的编码格式有冲突。
