Submit html form using ajax

Question

I'm trying to design a restaurant website as a project and every time I hit the submit button to order any food the page refreshes and jumps back to the top. I tried everything but can't figure out how to solve it.

This is what my button looks like at the moment:

  <div class="BestellButton">
                        <form action = "insertorder.php"  method ="post" >
                            <input type="hidden" name = "artikelnummer" value ="'.$row['Artikelnummer'].'"/>
                            <input type="hidden" name="URL" value= "Drinks.php" />
                            <button type = "submit">Bestellen</button>

                        </form>
                   </div>

Thanks for any help.

You can use ajax post request on button click, so page will not refresh.

var http = new XMLHttpRequest();
var url = "insertorder.php";
var params = 'name1=value1&name2=value2';
http.open('POST', url, true);

// post header
http.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');

http.onreadystatechange = function() {
    if(http.readyState == 4 && http.status == 200) {
        alert(http.responseText);
    }
}
http.send(params);

Also, on submit button click event, you have to use

preventDefault();

so page will not refresh on button click
