1. Traverse all attributes of the DOM object (all attributes will be traversed regardless of whether they are set in the HTML tag)

var obj=document.getElementById("btnToggleState") 
var s="";
for(var elem in obj)
   s+=elem+"\n";
alert(s);

2. Traverse the attributes set in the HTML tag of the DOM object

$.each($('#btnToggleState')[0].attributes,function(i,attrib){
  alert(i+":"+attrib.name+":"+attrib.value);
});
