How do I replace global RegExp matches with object literal values in JavaScript

Question

Using a function as the second parameter resulted in the desired effect:

var selector = ("'$greetings' '$friend'").replace(/\$([^']+)/g, expand)

function expand(match, offset, fullstring)
  {
  var dict =
    {
    ...
    };

  ...
  }

Which can be generalized into a tokenizer, such as the following:

/* Get all anchors with the javascript: URI scheme */
$("a[href*='javascript']").each(function () {
    javascriptURL(arguments[1])
})

/* Replace the javascript: URI with the URL within it */
function javascriptURL(anchor) {
    var hyperlink = $(anchor).attr("href").replace(/./g, replacer).substring(1).replace(/'/g, "");

    /* Class name for new window binding */
    var newWindow = "extWin";

    $(anchor).attr({
        "href": hyperlink,
        "class": newWindow
    });
}

/* Grab all text between window.open() parens */
function replacer(match, offset, fullstring) {
    var tokens = {
        "(": true,
        ",": false,
        ";": false
    };

    /* Consume everything after the left paren */  
    if (tokens[match] === true) {
        replacer.state = true
    }

    /* Discard everything after the first comma; also reset after a semicolon */
    if (tokens[match] === false) {
        replacer.state = false
    }

    /* Continue consuming or discarding otherwise */    
    if (tokens[match] === undefined) {
        replacer.state = replacer.state;
    }

    /* Return the consumed string or an empty string depending on the tokenizer state */
    if (replacer.state === true) {
        return match
    } 
    else {
        return "";
    }

}

function replace(pattern:*, repl:Object):String

repl:Object — Typically, the string that is inserted in place of the matching content. However, you can also specify a function as this parameter. If you specify a function, the string returned by the function is inserted in place of the matching content.
