You can grab a list of all attributes from your elements and test their value that way. This snippet handles both IE and WebKit browsers, and will return the string value of the CSS class:

var value = "";
var elements = document.getElementsByTagName("div");

for(var i = 0; i < elements.length; i++){
    if(typeof elements[i].attributes['class'] == "undefined"){
        value = elements[i].getAttribute("class"); 
    } else {
      value = elements[i].attributes['class'].nodeValue;
    }

    alert(value); // careful, this will be a lot of alerts
}
