To add an item into a JSON object in Knockout.js, you can use the following approach:
Here's an example code snippet:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
// Define a JSON object var json = { "items": [ { "name": "Item 1", "price": 10 }, { "name": "Item 2", "price": 20 } ] }; // Convert the JSON object into a Knockout observable array var items = ko.observableArray(json.items); // Add a new item to the observable array items.push({ "name": "Item 3", "price": 30 }); // Convert the observable array back to a JSON object var updatedJSON = { "items": items() }; console.log(updatedJSON); |
In the above code, we first convert the "items" array in the JSON object into a Knockout observable array using the ko.observableArray() function. Then, we use the push() method to add a new item to the observable array. Finally, we convert the updated observable array back to a JSON object by calling items().
