when sending json via ajax do you need to turn it into a string to send it?
If it isn't a string, then it isn't JSON in the first place.
JSON is a text based data format. HTTP is a text based communications protocol.
JSON stands for javascript object notation
JSON is based on the syntax for JavaScript literals. A JavaScript object is not JSON.
AJAX is all about HTTP requests, which are basically "text" requests to a server. That's the main reason why you have to stringify your object: That way it's turned into text that can "travel" over HTTP.
When sending data to a web server, the data has to be a string.
That's why we are using JSON.stringify() function to convert data to string and send it via XHR request to the server.
// Creating a XHR object let xhr = new XMLHttpRequest();
let url = "submit.php";
// open a connection
xhr.open("POST", url, true);
// Set the request header i.e. which type of content you are sending
xhr.setRequestHeader("Content-Type", "application/json");
// Converting JSON data to string
var data = JSON.stringify({ "name": name.value, "email": email.value });
// Sending data with the request
xhr.send(data);
