if (reAddLast == true) // If we are re-adding the originating script we do not care if it has already been added.

{

found = $('script').filter(function () {

return ($(this).attr('src') == scriptpath);

}).length != 0; // jQuery to check if the script already exists. (replace it with straight JavaScript if you don't like jQuery.

}
