How to send JSON in JS with POST Method

If you want to send JSON data using JavaScript, you can do that using the POST method. There are multiple ways to do so, and here are some of them:

Using XMLHttpRequest

You can use the XMLHttpRequest object to send JSON data. This method is widely used and supported by all modern browsers.

const xhr = new XMLHttpRequest();
const url = "your-url-here";
const data = JSON.stringify({
    name: "John",
    age: 30
});

xhr.open("POST", url, true);
xhr.setRequestHeader("Content-type", "application/json; charset=utf-8");
xhr.onload = function () {
    const response = JSON.parse(xhr.responseText);
    console.log(response);
};
xhr.send(data);

Using Fetch API

The Fetch API is a newer and more elegant way to send JSON data using JavaScript. It is supported by most modern browsers.

const url = "your-url-here";
const data = JSON.stringify({
    name: "John",
    age: 30
});

fetch(url, {
    method: "POST",
    headers: {
        "Content-type": "application/json; charset=utf-8"
    },
    body: data
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error(error));

Using jQuery

If you are already using jQuery in your project, you can use its ajax() method to send JSON data using JavaScript.

const url = "your-url-here";
const data = JSON.stringify({
    name: "John",
    age: 30
});

$.ajax({
    type: "POST",
    url: url,
    data: data,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (response) {
        console.log(response);
    },
    error: function (error) {
        console.error(error);
    }
});

These are some of the ways to send JSON data using JavaScript. You can choose the one that suits you the best. Hope this helps!
