Question

Would it be possible to create a system which executes a Ruby script on a VPS (according to what is entered in a client-browser) and then retrieve the data from the Ruby script or database?

Many thanks.

You can use AJAX. There is a tutorial on W3Schools and other places if you search. Here is an example:

<script type="text/javascript">

    function loadXMLDoc() {
        var xmlhttp;
        if (window.XMLHttpRequest) {
            // code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp=new XMLHttpRequest();
        }
        else {
            // code for IE6, IE5
            xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
        }

        xmlhttp.onreadystatechange=function() {
            if (xmlhttp.readyState==4 && xmlhttp.status==200) {
                document.getElementById("exampleDiv").innerHTML=xmlhttp.responseText;
            }
        }

        xmlhttp.open("GET","http://example.com/",true);
        xmlhttp.send();
    }

</script>

If you use jQuery or a similar library, the code would be a but simpler, but this will work. Between this example and the tutorial, I think you will be able to make it work. You can just plug in your URL and change the line that handles the response to whatever you need. Let me know how it goes.
