javascript to reverse order of values

How can I reverse the order of Duck, Donald with Javascript? I am currently retrieving Duck, Donald from a query string and I would like to be able to display it on the page, receiving it as Dondald Duck. I am using document.write("Name: " + Request.QueryString("name")); to write Duck, Donald to the page and I would also like to be able to change 'Mouse', 'Mickey G' to just 'Mickey Mouse'.

var name = Request.QueryString("name").Item(1).split(",").reverse().join(" ").trim();
if(name.split(" ").length > 2) {
            name = name.split(" ");
            name.splice(1, 1);
            name = name.join(" ");     
} 
document.write(name);

As above, but consider: Are first names and surnames always separated by commas? It becomes relevant with some non-English names you may find like 'Silva dos Santos, Miguel Jesus', where Silva dos Santos are the family names and Miguel Jesus are given names.

This function may help you.

<script>
function reverseName(str) {
    var tail = str.substr(0, str.indexOf(","));
    var head = str.substr(str.indexOf(",") + 1);

    return head + ' ' + tail;
}

document.write("Name: " + reverseName(Request.QueryString("name")));
</script>

You can split the string using split method, and then past them in correct order:

var str = 'Duck, Donald';
var parts = str.split(',');
document.write(parts[1] + ' ' + parts[0]);

Basically thats what you need to do. Hope it helps!
