What you’re after is this code:

<script type="text/javascript">
window.onload = function WindowLoad() {
    var arrLinks = document.getElementsByTagName("a");
    for (var i = 0; i < arrLinks.length; i++) {
        var oLink = arrLinks[i];
        var sCurHref = oLink.href;
        if (sCurHref.indexOf("?id=") >= 0) {
            var ID = sCurHref.split("?id=")[1];
            if (ID.length > 0) {
                oLink.id = ID;
                oLink.href = "#";
                oLink.onclick = function() {
                    document.location.href = sCurHref;
                    return false;
                }
            }
        }
    }
}
</script>

This will iterate all the links, changing the visible HREF to “#” and preserving their functionality, applying the proper ID. (Though you didn’t say what’s the use of that ID)
