Note: Most modern browsers will now allow you to navigate objects in the developer console. This answer is antiquated.
This method will walk through object properties and write them to the console with increasing indent:
function enumerate(o,s){
//if s isn't defined, set it to an empty string
s = typeof s !== 'undefined' ? s : "";
//if o is null, we need to output and bail
if(typeof o == "object" && o === null){
console.log(s+k+": null");
} else {
//iterate across o, passing keys as k and values as v
$.each(o, function(k,v){
//if v has nested depth
if(typeof v == "object" && v !== null){
//write the key to the console
console.log(s+k+": ");
//recursively call enumerate on the nested properties
enumerate(v,s+" ");
} else {
//log the key & value
console.log(s+k+": "+String(v));
}
});
}
}
Just pass it the object you want to iterate through:
var response = $.ajax({
url: myurl,
dataType: "json"
})
.done(function(a){
console.log("Returned values:");
enumerate(a);
})
.fail(function(){ console.log("request failed");});
