Unveiling Insights from a JSON File: Data Extraction

I have a JSON file named pio2.json that contains the following data:

{
"controles":[{
        "chart":[{
            "type":"columns",
            "title":"Pollitos"
        }],
        "datos":[{"key":"Math","value":98},
                 {"key":"Physics","value":78},
                 {"key":"Biology","value":70},
                 {"key":"Chemistry","value":90},
                 {"key":"Literature","value":79}
                ]
        }]
}

My goal is to extract data from the "datos" array for use in an HTML/JavaScript chart.

$(function () {
    var processed_json = new Array(); 
    $.getJSON('pio2.json', function(data)
    {
        // Populate series
        for (i = 0; i < data.controles.length; i++){
            processed_json.push(data.controles[i].chart);
        }
    }
}

Do you have any suggestions on how to achieve this?

Answer №1

Uncertain about the nature of your problem. The process involves serialization on the server side and deserialization on the client side, resulting in an array format.

Answer №2

After placing your data into json1.json and making some slight modifications in the code, everything worked smoothly. I successfully extracted the results from the json file and displayed them on my html page.

<body>
    <script type="text/javascript">
         $(document).ready(function () {
             var processed_json = new Array(); 
             $.getJSON('json1.json', function(data)
             {
                 // Populate series
                 for (i = 0; i < data.controles.length; i++){
                     processed_json.push(data.controles[i].chart);
                 }
             })
         });  
    </script>
</body>
