.replace with a callback function is your tool of choice when parsing custom formats in javascript. Consider:

parse = function(s) {
    var result = {};
    s.replace(/^(\w+)|\[(.+?)=(.+?)\]/g, function($0, $1, $2, $3) {
        result[$2 || "kind"] = $1 || $3;
    });
    return result;
}

Example:

str = "car[brand=saab][wheels=4][price=1234][morestuff=foobar]"
console.log(parse(str))
// {"kind":"car","brand":"saab","wheels":"4","price":"1234","morestuff":"foobar"}
