Sending JSON to server using AJAX in JavaScript
You can send data to a server in the form of JSON. This is done in the following way:
button.addEventListener('click', function() {
let promise = fetch('/handler/', {
method: 'post',
body: JSON.stringify([1, 2, 3, 4, 5]),
headers: {
'Content-Type': 'application/json',
},
});
});
On the server, the request body
will be in body:
export default {
'/handler/': function({ body }) {
console.log(body);
}
}
Let's unpack the JSON received by the server:
export default {
'/handler/': function({ body }) {
console.log(JSON.parse(body));
}
}
Send an array of data to a server. Let the server find the sum of this array elements and send back.
