Json - Insert a new object between array elements

Question

I have a json object , when looped through using a foreach outputs the below :

{"Comment": {"id":"1","post_id":"31","created":"14263241"} , "User": {"fname":"Test","lname":"Test2"} } 

{"Comment": {"id":"2","post_id":"32","created":"14263257"} , "User": {"fname":"Lionel","lname":"Messi"} }

Where created is a timestamp .

Using a condition from another array , i want to be able to insert a new element in the second array so that it becomes like this :

{"Comment": {"id":"2","post_id":"32","created":"14263257"} , "User": {"fname":"Lionel","lname":"Messi"}, "Status":{"status":"add","userid":"10"} }

where "Status":{"status":"add","userid":"10"} will be from another json object .

Any help would be appreciated .

I assume your JSON is on the format

var json = [
  {"Comment": {"id":"1","post_id":"31","created":"14263241"} , "User": {"fname":"Test","lname":"Test2"} }, 
  {"Comment": {"id":"2","post_id":"32","created":"14263257"} , "User": {"fname":"Lionel","lname":"Messi"} } 
];

And your "another array" holds an item like this

var otherJson = {"id":"2", "Status":{"status":"add","userid":"10"} }

Then iterate over each element in the first json and insert Status from otherJson when the criteria match :

for (var index in json) {
    if (json[index].Comment.id == otherJson.id) {
        json[index].Status = otherJson.Status;
    }      
}

The item with the Comment.id 2 is now enriched with Status.
