Ajax return garbled Solution

1. vbs conversion functions
The vbs conversion function:
Function convertstr (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 returns & CHR (clng (thischarcode) * & h100 + CINT (nextcharcode ))
I = I + 1
End if
Next
Convertstr = strreturn
End Function

For example
// Ajax Processing
VaR http_request = false;
Function send_request (URL, OBJ) {// initialize, specify the processing function, and send the request Function
VaR OBJ = OBJ;
Http_request = false; // start to initialize the XMLHTTPRequest object.
If (window. XMLHttpRequest) {// Mozilla Browser
Http_request = new XMLHttpRequest ();
If (http_request.overridemimetype) {// sets the mime category
Http_request.overridemimetype ("text/html"); // sets gb2312 encoding to identify data.
}
} Else if (window. activexobject) {// IE browser
Try {
Http_request = new activexobject ("msxml2.xmlhttp ");
} Catch (e ){
Try {
Http_request = new activexobject ("Microsoft. XMLHTTP ");
} Catch (e ){}
}
}
If (! Http_request) {// exception. An error occurred while creating the object instance.
Window. Alert ("the XMLHTTPRequest object instance cannot be created .");
Return false;
}
Http_request.onreadystatechange = function (){
If (http_request.readystate = 4) {// judge the object status
If (http_request.status = 200) {// The information has been returned successfully. Start to process the information.
Gb2utf8_data = http_request.responsebody;
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 ");
Document. getelementbyid (OBJ). innerhtml = bytes2bstr (http_request.responsebody );
// Alert (bytes2bstr (http_request.responsebody ));
} Else {// The page is abnormal.
Document. getelementbyid (OBJ). innerhtml = "error! Access timeout! "
}
}
}
Http_request.open ("Post", URL, true );
Http_request.send (null );
} // Function for processing the returned information

2. Use the JS Conversion Function gb2utf8:

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. 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 = glbencode [k] + T. substring (4 );
}
Gb2utf8_data = gb2utf8_char = NULL;
Return Unescape (T. Join ("% "));
}

The usage is the same as above, for example:
Document. getelementbyid (OBJ). innerhtml = gb2utf8 (http_request.responsebody );
