I'm fairly new to JavaScript and AJAX, but I'm trying to take an AJAX's requests' response text and split it into an array (the response text is ma separated). Here's the error I get:

Uncaught TypeError: object is not a function localhost:36 myrequest.onreadystatechange

Here's my code:

var currentpicid;
var currentcat;
var currentindex;
myrequest.onreadystatechange=function(){
    if (myrequest.readyState==4 && myrequest.status==200){ //request successful
        var infoarray = myrequest.responseText.split(',');
        currentpicid = infoarray(0);
        currentcat = "top";
        currentindex = index;

        document.getElementById("image").innerHTML=myrequest.responseText;
    }
}

Can anyone help me? I have verified that my PHP page is just outputting a ma separated list of values. Thanks!

Instead of:

currentpicid = infoarray(0);

you need:

currentpicid = infoarray[0];

The parentheses are for function calls. Use square brackets for array indexes.
