Answer 1

Use Ajax to send data but do not use xmlHttpRequest directly in your code.

Use a popular javascript library like jquery to send data to the server.

Edit: Removed irrelevant parts about browser compatibility.

Answer 2

Jan Hančič is right : the best way is to use XMLHttpRequest.

Here's an example :

var xhr = new XMLHttpRequest();
xhr.open("post", "http://ex.ample.com/file.php", true);
xhr.onreadystatechange = function() {
    if(this.readyState == 4) {
        // Do something with this.responseText
    }
}
xhr.send("var1=val1&var2=val2");

There are plenty of tutorials and references on the web about AJAX and the xhr object.
