How can I delete a query string parameter in JavaScript?

Question

Is there better way to delete a parameter from a query string in a URL string in standard JavaScript other than by using a regular expression?

Here's what I've come up with so far which seems to work in my tests, but I don't like to reinvent querystring parsing!

function RemoveParameterFromUrl( url, parameter ) {

    if( typeof parameter == "undefined" || parameter == null || parameter == "" ) throw new Error( "parameter is required" );

    url = url.replace( new RegExp( "\\b" + parameter + "=[^&;]+[&;]?", "gi" ), "" ); "$1" );

    // remove any leftover crud
    url = url.replace( /[&;]$/, "" );

    return url;
}

If you're into jQuery, there is a good query string manipulation plugin:

Thanks, removed - it was bound to go stale after a couple of years! :)
