javascript parsing question

hi,

I'm having some serious trouble trying to parse a JSON file in javascript. I have done this outside of max with no (well maybe some) issues..

Basically I'm making an XMLHttp request in the exact same way as documented in the "maxurl" helpfile.

this is my .js file so far.

var ajaxreq;

function readystatechange_parsejson()
{
        if (this.readyState ==4 && this.status == 200){
        post(this.responseText,"\n");
        var myobj = JSON.parse(this.responseText);
    post(myobj.list);

}

function fget(){

    ajaxreq = new XMLHttpRequest();
    ajaxreq.open("GET","https://api.myjson.com/bins/3ymxq");
    ajaxreq.onreadystatechange = readystatechange_parsejson;
    ajaxreq.send();
}

it keeps telling me that myobj.list is undefined therefore i can't use it in a for loop to iterate through the json..

when posting the myobj variable it just gives it a jsobject number and no information..

maybe i should just use JSON.stringify as that is actually giving me a string to play with..

help??
