You will get the clear answer, if you provide the JSON structure.
For example, if you have below JSON structure.
var json={ “id”:23,”name”:”marko”};
for(key in json){
alert(key+'->'+json[key]);
}
It's not simple for above single node json. If JSON structure is deeper, you need to iterate till you get value :)
Or. Rather easiest way is do console.log(json); and see in firebug, you will get what is inside json block.
