Question

{
"elements":[{
        "content":{
            "xyz-media:game":{

                "display_name":"Pool Practice",

How do i parse this JSON String? I have been trying this for last 2 days without any luck. Below is the code that I have been trying.

//where r.responseText is the Response from URL
messages = JSON.parse(r.responseText);

//To access the display_name of first content
messages.elements[0].content[0].display_name

Please tell me where am i going wrong?

Elements is an array of maps . That is element[0] is a map with one of ther keys as content and the value of content is a map again, So there isn't any elements[0].content[0]. You access it as element[0]["content"] or element[0].content but note there is no [0] for content, as it is not an array, and you proceed so on to access other values.
