javascript send post request
let data = {element: "barium"};

method: "POST",
body: JSON.stringify(data)
}).then(res => {
console.log("Request complete! response:", res);

// If you are as lazy as me (or just prefer a shortcut/helper):
window.post = function(url, data) {
return fetch(url, {method: "POST", body: JSON.stringify(data)});

// ...

var xhr = new XMLHttpRequest();

//Send the proper header information along with the request
xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
xhr.onload = function() {//Call a function when the state changes.
if(xhr.status == 200) {

// Use these functions:
function _GET_REQUEST(url, response) {
var xhttp;
if (window.XMLHttpRequest) {
xhttp = new XMLHttpRequest();
} else {
xhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
response(this.responseText);
}
};
xhttp.open("GET", url, true);
xhttp.send();
}

}
};
xhttp.open("POST", url, true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhttp.send(params);
}
// Use like:
_GET_REQUEST('http://url.com', (response) => {
// Do something with variable response
console.log(response);
});
_POST_REQUEST('http://url.com', 'parameter=sometext', (response) => {

});What XMLHttpRequest method must be used to send a POST request to the server?
var url = "get_data.php";
var params = "lorem=ipsum&name=binny";
http.open("POST", url, true);
//Send the proper header information along with the request
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", params.length);
http.setRequestHeader("Connection", "close");
