make objects and fields dynamically in javascript

- by acidzombie24

instead of using getParameterByName('Field', PostData) (PostData == $('form').serialize();) I would like to write PostData.Field, how can i do that with javascript?

how do I access XHR responseBody from Javascript?

I've got a web page that uses XMLHttpRequest to download a binary resource. Because it's binary I'm trying to use xhr.responseBody to access the bytes. I've seen a few posts suggesting that it's impossible to access the bytes directly from Javascript. This sounds crazy to me. Weirdly, xhr.responseBody is accessible from VBScript, so the suggestion is that I must define a method in VBScript in the webpage, and then call that method from Javascript. See jsdap for one example. var IE_HACK = (/msie/i.test(navigator.userAgent) && !/opera/i.test(navigator.userAgent)); if (IE_HACK) document.write('<script type="text/vbscript">\n\ Function BinaryToArray(Binary)\n\ Dim i\n\ ReDim byteArray(LenB(Binary))\n\ For i = 1 To LenB(Binary)\n\ byteArray(i-1) = AscB(MidB(Binary, i, 1))\n\ Next\n\ BinaryToArray = byteArray\n\ End Function\n\ </script>'); var xml = (window.XMLHttpRequest) ? new XMLHttpRequest() // Mozilla/Safari/IE7+ : (window.ActiveXObject) ? new ActiveXObject("MSXML2.XMLHTTP") // IE6 : null; // Commodore 64? xml.open("GET", url, true); if (xml.overrideMimeType) { xml.overrideMimeType('text/plain; charset=x-user-defined'); } else { xml.setRequestHeader('Accept-Charset', 'x-user-defined'); } xml.onreadystatechange = function() { if (xml.readyState == 4) { if (!binary) { callback(xml.responseText); } else if (IE_HACK) { // call a VBScript method to copy every single byte callback(BinaryToArray(xml.responseBody).toArray()); } else { callback(getBuffer(xml.responseText)); } } }; xml.send(''); Is this really true? The best way? copying every byte? For a large binary stream that's not gonna be very efficient. There is also a possible technique using ADODB.Stream, which is a COM equivalent of a MemoryStream. See here for an example. It does not require VBScript but does require a separate COM object. if (typeof (ActiveXObject) != "undefined" && typeof (httpRequest.responseBody) != "undefined") { // Convert httpRequest.responseBody byte stream to shift_jis encoded string var stream = new ActiveXObject("ADODB.Stream"); stream.Type = 1; // adTypeBinary stream.Open (); stream.Write (httpRequest.responseBody); stream.Position = 0; stream.Type = 1; // adTypeBinary; stream.Read.... /// ???? what here } I don't think that's gonna work - ADODB.Stream is disabled on most machines these days. In The IE8 developer tools - the IE equivalent of Firebug - I can see the responseBody is an array of bytes and I can even see the bytes themselves. The data is right there. I don't understand why I can't get to it. Is it possible for me to read it with responseText? hints? (other than defining a VBScript method)
