Add a fresh item into an array in Json between existing elements

Question

Add a fresh item into an array in Json between existing elements

After looping through a JSON object using foreach, the output is as follows:

{"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"} }

The 'created' field in the JSON object represents a timestamp.

I am looking to add a new element in the second array based on a condition from another array. This will transform the array into:

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

The content of

"Status":{"status":"add","userid":"10"}

will come from another JSON object.

Any assistance on accomplishing this task would be greatly appreciated.

Answer №1

If your JSON data follows this structure:

var jsonData = [
  {"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 you have another array containing an item like this:

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

To update each element in the initial jsonData with the appropriate Status from

additionalData</code, you can use the following loop:</p>

<pre><code>for (var i in jsonData) {
    if (jsonData[i].Comment.id == additionalData.id) {
        jsonData[i].Status = additionalData.Status;
    }      
}

Now, the entry with the Comment.id of 2 has been enhanced with the corresponding Status.
