Question

Okay so when I usually work with JSON I collect data like this:

<?php 
    $some_array = array("success" => "The upload is successful", "failed" => "The upload has failed");
    echo  json_encode($some_array);
?>

<script type="text/javascript">
    success: function(data){
        var imported = $.parseJSON(data);
        ...
    }
</script>

but I I’m currently trying to figure a jquery plugin that uses responseJSON and I’m not sure how to use it:

onComplete: function(id, fileName, responseJSON) {
    if (responseJSON.success) {

How does this work?

Answer 1

You can console.log(responseJSON) to get a look at the complete object.

Edit

The main difference here I would say is that data is a JSON string and accessing it as an object requires one to use parseJSON on it.

It seems responseJSON is already a JSON serialized object and as such you are able to immediately access it’s properties without the need to use parseJSON.
