The garbled of Get and post when JS calls Ajax

  When using "get", the crawled page is finally encoded with the encoding type  

  Code as follows: <%  server-side: Servletactioncontext.getresponse (). setcharacterencoding ("Utf-8");  client page effects p/ jsp.html target=_blank >jsp Tutorial: <%@ 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 "' This is the key, otherwise there will be garbled   Response.Write" Chinese characters "%>    2, in the use of the post with VBScript to solve the coding problem:  source code is as follows:     Code as follows: <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 = Strre Turn & thischr  else  innercode = ASC (THISCHR)   if Innercode < 0 then  Innercode = innercode + &h10000  End if  Hight8 = (Innercode and &hff00) &hff  low8 = Innercode and &Amp;hff  Strreturn = strreturn & "%" & Hex (HIGHT8) & "%" & Hex (LOW8)   end if  next  URL encoding = strreturn  End function  function Bytes2bstr (vin)   Strreturn = ""   For i = 1 to LenB (VIN) &N Bsp Thischarcode = ASCB (MidB (vin,i,1))   If Thischarcode < &h80 then  Strreturn = strreturn & Chr (Thischar Code)   else  Nextcharcode = ASCB (MidB (vin,i+1,1))   Strreturn = Strreturn & Chr (CLng (thischarcode) * &A mp;h100 + CInt (nextcharcode))   i = i + 1  end if  next  bytes2bstr = strreturn  End function&nbsp ; </script>    Below is the use of VBScript functions:    code as follows: <script language= Web Effects > /**  * Initializes a XMLHTTP object   */  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 (); }&nbsp ; Return ajax; }  function saveuserinfo ()   {  var msg = document.getElementById ("msg");  var f = d ocument.user_info;  var username = f.user_name.value;  var userage = f.user_age.value;  var usersex = F.use r_sex.value;  var url = "save.asp tutorial";  var poststr = urlencoding ("user_name=" + username + "&user_age=" + user Age + "&user_sex=" + usersex)//post with Encoding pass   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 = =) {  msg.innerhtml = Bytes2bstr (ajax.responsebody); Get time decoding  } } }  </script>  <form name= "User_info" >  Name: <textarea name= " User_name "/></TEXTAREA><BR/>  Age: <input type= "text" name= "user_age"/><br/>  Sex: <input Type= "text" name= "User_sex"/><br/>  <input type= "button" value= "Submit Form" onclick= "Saveuserinfo ()" >   </form>  <div id= "MSG" ></div>  success
