Mastering the art of correctly parsing JSON files with pure JavaScript

I've been struggling with creating HTML selectors and retrieving their values from JSON. I attempted to read the JSON data by adding a script tag to the HTML document and parsing it into a variable using JavaScript. However, this approach didn't seem to work as expected, and the solutions I found online were not very helpful.

Here is the HTML setup:

<body>
    <form>
        <label>Select list</label>
        <select id = "Countries">

        </select>
        <select id = "Bands">

        </select>
        <select id = "Albums">

        </select>   
    </form> 
    <script src="data.json"></script>
    <script src="script.js"></script>
</body>

And the JavaScript code snippet:

const data = JSON.parse(data);

Answer №1

If you need to retrieve JSON data, using a script tag will not work. Instead, you can fetch the JSON data in your script.js file by utilizing the fetch method:

fetch("data.json")
.then(response => {
    if (!response.ok) {
        throw new Error("HTTP error " + response.status);
    }
    return response.json();
})
.then(data => {
    // Utilize the parsed data here
})
.catch(error => {
    // Handle or report any errors here
});

Did you give this a shot:

$.get('yourData.json', function(info) {
    var array= [];
      $.each( info, function( index, value ) {
    var tempArray=[index,value]
        array.push( tempArray );
      });
    });
