Question

I am trying to post a variable to php method but when i am trying through XMLHttpRequest, in browser console i am getting XHR finished loading: POST immediate after this i get XHR finished loading: GET which i didn't called.

here is javascript

var http = new XMLHttpRequest();
var params = 'file=' + e;
http.open('POST', 'http://localhost:8080/admin/fm/deleteFile', true);

//Send the proper header information along with the request
http.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');

http.onreadystatechange = function() {//Call a function when the state changes.
    if(http.readyState == 4 && http.status == 200) {
        alert(http.responseText);
    }
}
http.send(params);
}

public function deleteFile(){
    return $this->request->getPost('file');
