I've got the same problem, and the answer is simple using ajax XmlHttpRequest:

// send a request, but don't refresh page
xhttp = new XMLHttpRequest();
xhttp.open("GET", "your script action", true);
xhttp.send();

Here's a small example, calling current script with parameters "like", embedded in a function:

function likeStuffs()
{
    // send a request, but don't refresh page
    xhttp = new XMLHttpRequest();
    xhttp.open("GET", "?like", true);
    xhttp.send();
}
