Get the filename from upload form using Javascript

I needed a way to access the filename of a file being uploaded or attached using the input file from a form. So, I created a nice little function to achieve this. Hopefully it comes in handy for someone.

<script type="text/javascript">
function getNameFromPath(strFilepath) {
    var objRE = new RegExp(/([^\/\\]+)$/);
    var strName = objRE.exec(strFilepath);

    if (strName == null) {
        return null;
    }
    else {
        return strName[0];
    }
}
</script>
