Sending a POST request in Simple Javascript

So recently i wanted to send a POST request to one of my backends using only simple plain Javascript. Found this code on Quora which worked nicely.


Code :

1. xhr = new XMLHttpRequest();
2. var url = "url";
3. xhr.open("POST", url, true);
4. xhr.setRequestHeader("Content-type", "application/json");
5. xhr.onreadystatechange = function () {
6. if (xhr.readyState == 4 && xhr.status == 200) {
7. var json = JSON.parse(xhr.responseText);
8. console.log(json.email + ", " + json.name)
9. }
10. }
11. var data = JSON.stringify({"email":"tomb@raider.com","name":"LaraCroft"});
12. xhr.send(data);
