ajax post get 亂碼解決方案

在使用"get"時，抓取的頁面最後加上編碼類別型
<%

伺服器端：servletactioncontext.getresponse().setcharacterencoding("utf-8");
用戶端 網頁特效p/jsp.html target=_blank >jsp教程： <%@ page language="java" contenttype="text/html; charset=utf-8" pageencoding="utf-8"%>

response.expires = -9999 
response.addheader "pragma","no-cache"
response.addheader "cache-ctrol","no-cache"
response.addheader "content-type","text/html; charset=gb2312"'這是重點，否則會出現亂碼
response.write "中文漢字"%>

2、在使用post時用vbscript解決了編碼問題：

源碼如下：

<script language="vbscript">
function urlencoding(vstrin)
  strreturn = ""
  for i = 1 to len(vstrin)
  thischr = mid(vstrin,i,1)
  if abs(asc(thischr)) < &hff then
  strreturn = strreturn & thischr
  else
  innercode = asc(thischr)
  if innercode < 0 then
  innercode = innercode + &h10000
  end if
  hight8 = (innercode and &hff00) &hff
  low8 = innercode and &hff
  strreturn = strreturn & "%" & hex(hight8) & "%" & hex(low8)
  end if
  next
  urlencoding = strreturn
end function

function bytes2bstr(vin)
  strreturn = ""
  for i = 1 to lenb(vin)
  thischarcode = ascb(midb(vin,i,1))
  if thischarcode < &h80 then
  strreturn = strreturn & chr(thischarcode)
  else
  nextcharcode = ascb(midb(vin,i+1,1))
  strreturn = strreturn & chr(clng(thischarcode) * &h100 + cint(nextcharcode))
  i = i + 1
  end if
  next
  bytes2bstr = strreturn
end function
</script>

下面是使用vbscript函數：

<script language=網頁特效>
  /**
  * 初始化一個xmlhttp對象
  */
  function initajax()
  {
  var ajax=false; 
  try { 
  ajax = new activexobject("msxml2.xmlhttp"); 
  } catch (e) { 
  try { 
  ajax = new activexobject("microsoft.xmlhttp"); 
  } catch (e) { 
  ajax = false; 
  } 
  }
  if (!ajax && typeof xmlhttprequest!='undefined') { 
  ajax = new xmlhttprequest(); 
  } 
  return ajax;
  }
  function saveuserinfo()
  {
  var msg = document.getelementbyid("msg");
  var f = document.user_info;
  var username = f.user_name.value;
  var userage = f.user_age.value;
  var usersex = f.user_sex.value;
  var url = "save.asp教程";
  var poststr = urlencoding("user_name="+ username +"&user_age="+ userage +"&user_sex="+ usersex);//post時採用編碼傳遞

  var ajax = initajax();
  ajax.open("post", url, true); 
  ajax.setrequestheader("content-type","application/x-www-form-urlencoded"); 
  ajax.send(poststr);

  ajax.onreadystatechange = function() { 
  if (ajax.readystate == 4 && ajax.status == 200) { 
  msg.innerhtml = bytes2bstr(ajax.responsebody); //擷取時解碼
  } 
  } 
  }
  
</script>

<form name="user_info">
 姓名：<textarea name="user_name" /></textarea><br />
 年齡：<input type="text" name="user_age" /><br />
 性別：<input type="text" name="user_sex" /><br />
 <input type="button" value="提交表單" onclick="saveuserinfo()">
</form>
<div id="msg"></div>
成功
