``There seems to be an issue with the functionality of JSON.stringify

Upon attempting to use the JSON.stringify() method to convert an array of strings into a JSON object for passing to a PHP script, I encountered an issue where the method did not return any meaningful output.

The code provided is the only one handling the input, without interference from any other sources.

function submitItem() {
 try {
    var item = [];
    item.name = $('.itemText').val();
    item.type = $('.itemType').val();
    item.price = $('.itemPrice').val();
    item.color = $('.itemColor').val();
    item.desc = $('.itemDesc').val();
    item.image = $('.itemImage').val();
    item.giftType = $('.itemGiftType').val();
    item.avail = $('.itemAvail').val();
    item.giftable = $('.itemGiftable').val();
    item.ranking = $('.itemRanking').val();
    item.basicTrack = $('.itemBasic').val();
    item.vetTrack = $('.itemVet').val();
    item.month = $('.itemMonth').is(':checked');
    item.hidden = $('.itemHidden').is(':checked');
    item.id = $('.itemID').val();

     // For confirmation purposes
    var join = [];
    join[0] = 'test';
    join[1] = 'tset';
    console.log( JSON.stringify( join ) );

    console.log(item);
    var JsonItem = JSON.stringify(item);
    console.log( JsonItem );
 } catch (err) {
    console.log(err.message);
 }
}

The console displays the following output:

Instead of a valid JSON string, both logs show []. Any insights into why this might be happening would be greatly appreciated.

Thank you.

Answer №1

Instead of initializing your "item" as an array, you should initialize it as a plain object ({}):

var item = {};

The JSON serializer only operates on numerically-indexed properties when it encounters an actual array.

Answer №2

To ensure proper conversion, it is recommended to convert the join into an object before using stringify method

console.log( JSON.stringify( {data: join}) );
