Yes there is. However, if you want saf and iem support on the Mac it's
gonna be a long winded one. Also, op didn't support this before
version 7.5. I've not tested doing this on shiira or omniweb, so I
will not even bother with coding for them right now.

function loadScript(address){
    var
        m=/mac/i.test(navigator.platform),
        a=window.ActiveXObject||false,
        x=window.XMLHttpRequest||false,
        s=/apple/i.test(navigator.vendor),
        script;
    // First we do the op7.5/moz/iew solution.
    // No feature detection necessary, all other browsers will just
gracefully fail.
    (script=document.createElement('script')).setAttribute('type','text/javascript');
    script.setAttribute.src=address;
    document.getElementsByTagName('head').item(0).appendChild(script);
    // Okay, that done. How about iem, then?
    if(m&&a)
        document.createElement('div').innerHTML='<script
type="text/javascript" src="'+address+'"><\/script>';
        // You don't even have to insert it into the document!
    // Okay, saf left.
    if(m&&s){
        x.open('GET',address,false);
        x.send(null);
        eval(x.responseText);
    }
}
