Answer 1

I would do something like

var reg = /.*addr=([^&]*)/;
var str = 'http://maps.google.com/maps?f=d&daddr=8467+ Perimeter+ Rd.+S+ Seattle+ Washington+ 98108';
var matches = reg.exec(str);
var address = matches[1].split("+").join(" ");

Answer 2

I made this crunched down function which acts as an equivalent to PHP's $_GET variable:

function _GET(key, def){

        try{
            return RegExp('[?&]'+key+'=([^?&]*)').exec(location.href)[1]
        }catch(err){
            return !def?'':def
        }

    }

this function makes it easily possible to get multiple query strings from the same web address.

//url: 'yoursite.com?f=d&daddr=8467+Perimeter+Rd.+S+Seattle+Washington+98108'

    var SEARCH = _GET('daddr').replace(/[\+]/g, ' ')
    alert(SEARCH)
