Ways to extract information from json response

I've got a JSON output that has this structure.

{
   "38467": {
      "name": "Tony Parker",
      "book": [
         {
            "title": {
               "name": "MediaWorks"
            },
         },
       ],
   }
   "59678": {
      "name": "Ray Thomas",
   }
}

The actual JSON output is much longer, but I only want to store the author's name and their publisher. I need to save multiple individual records for a single model.

I am currently using jQuery to assign values to input elements.

  $('#Author' + i + 'Title').val(response...);

However, it seems that this method is not working as expected.

Your help would be greatly appreciated.

Thank you.

JSON stands for JavaScript Object Notation and is essentially a way to store and transmit data in a readable format. By decoding the JSON data and assigning it to a variable, such as var jsonData, you can then access its elements like a regular JavaScript object or array: jsonData[12345]['property'] contains the value of that property.

Additional note:

After storing and decoding the JSON data, you can iterate over it using a standard JavaScript forEach loop:

for (var key in dataList) {
   var item = dataList[key]['name'];
   var description =  dataList[key]['details'][0]['description']['text'];
   // ...perform actions here...
}

JSON itself isn't complex; it's just a structured way to organize information for easy transfer. If you're utilizing libraries like jQuery or MooTools, consider using their built-in methods like .each() for traversing JSON objects instead of native JavaScript features, which may add unnecessary overhead.
