1// For a plain JS solution, use these functions:
2
3function _GET_REQUEST(url, response) {
4  var xhttp;
5  if (window.XMLHttpRequest) {
6    xhttp = new XMLHttpRequest();
7  } else {
8    xhttp = new ActiveXObject("Microsoft.XMLHTTP");
9  }
10
11  xhttp.onreadystatechange = function() {
12    if (this.readyState == 4 && this.status == 200) {
13      response(this.responseText);
14    }
15  };
16
17  xhttp.open("GET", url, true);
18  xhttp.send();
19}
20
21function _POST_REQUEST(url, params, response) {
22  var xhttp;
23  if (window.XMLHttpRequest) {
24    xhttp = new XMLHttpRequest();
25  } else {
26    xhttp = new ActiveXObject("Microsoft.XMLHTTP");
27  }
28
29  xhttp.onreadystatechange = function() {
30    if (this.readyState == 4 && this.status == 200) {
31      response(this.responseText);
32    }
33  };
34
35  xhttp.open("POST", url, true);
36  xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
37  xhttp.send(params);
38}
39
40// and apply like this:
41_GET_REQUEST('http://someurl', (response) => {
42	// do something with variable response
43});
44_POST_REQUEST('http://someurl', 'paramx=y', (response) => {
45	// do something with variable response
46});
