Handling JSON objects with JQuery

Question

Hello i am having a weird issue where i am trying to get the id of the last element in a json object array.

$.ajax ({
    type: 'POST',
    url: 'post-get.php',
    data:
    {
        group: group,
        postid: postid
    },
    cache: false,
    dataType: 'json',
    success: function(response) {
        if (response.length > 0)
        {
            $.each(response, function(index, element) {
                var p = "";
                p += "<div class='col-md-12' style='padding:0'>"; // start col-md-12
                p += "<div class='user'>"; // start user
                p += "<div class='pic'>"; // start pic
                p += "<img src='img/timthumb.php?src=";
                p += element[2];
                p += "&w=100&h=100&a=t' />";
                p += "</div>"; // end pic
                p += "<span class='username'>"; // start username
                p += element[1];
                p += "</span>"; // end username
                p += "</div>";// end user
                p += "<div class='content'>"; // start content
                p += element[4];
                p += "</div>"; // end content
                p += "<div class='clear'></div>";
                p += "<div class='info' style='margin-top:20px;'>"; // start info
                p += "<div class='datetime'>Posted on: ";// start datetime
                p += element[5];
                p += "</div>"; // end datetime
                p += "<div class='clear'></div>";
                p += "</div>";  // end info
                p += "</div>"; // end col-md-12
                p += "<div class='clear'></div>";

                $(".post").html($(".post").html() + p + element[6]);
            });
        }
    }
});

on this line: $(".post").html($(".post").html() + p + element[6]); element[6] refers to the post id, it should add the post id of each post and display it on the page but it keeps on repeating only the id of the first post in the returned array.

This is the response returned from the server.

In your json, the value of the property with the key of `6` is `8`.. for _every_ object in the array. — Jason P, Jun 05 '14 at 18:01

Try using accessing the property name like this, as you have data repeated two times you can remove repeated data from service. and also can access by real property names instead of number that would be easy to understand.

var p = "";
p += "<div class='col-md-12' style='padding:0'>"; // start col-md-12
p += "<div class='user'>"; // start user
p += "<div class='pic'>"; // start pic
p += "<img src='img/timthumb.php?src=";
p += element["2"];
p += "&w=100&h=100&a=t' />";
p += "</div>"; // end pic
p += "<span class='username'>"; // start username
p += element["1"];
p += "</span>"; // end username
p += "</div>";// end user
p += "<div class='content'>"; // start content
p += element["4"];
p += "</div>"; // end content
p += "<div class='clear'></div>";
p += "<div class='info' style='margin-top:20px;'>"; // start info
p += "<div class='datetime'>Posted on: ";// start datetime
p += element["5"];
p += "</div>"; // end datetime
p += "<div class='clear'></div>";
p += "</div>";  // end info
p += "</div>"; // end col-md-12
p += "<div class='clear'></div>";

$(".post").html($(".post").html() + p + element["6"]);
