Decoding URL parameters with JavaScript

Question

This should be a simple task, but I can\'t seem to find a solution.

I created my own string methods to support the needed encoding/decoding. These methods will handle the + encoding and decoding properly, allowing you to have plusses (+) in your string and still have the original spaces be encoded as +'s.

String.prototype.plusEncode = function() {
    return encodeURIComponent(this).replace(/\%20/gm,"+");
}

String.prototype.plusDecode = function() {
    return decodeURIComponent(this.replace(/\+/gm,"%20"));
}
