function QueryString(path)
  {
  	this.path = path;
	this.toString = function()
	{
		result = this.path + "?";
		for(element in this)
		{
			if(typeof this[element] != 'function' && element != 'path')
			{
				result += element + "=" + this[element] + "&";
			}
		}
		return result;
	}
	
	this.toLink = function(text)
	{
		return "<a href=\"" + this.toString() + "\">" + text + "</a>";
	}
  }

Now i can get rid of mess link this:
url = '/pictures/crop?id=<%= @picture.id  %>' +
				'&w=' + dd_picturer.w + 
				'&h=' + dd_picturer.h +
				'&sx=' + (dd_crop.x - dd_picturer.x) + '&sy=' + 
				(dd_crop.y - dd_picturer.y) + '&ex=' +
				 dd_crop.w + '&ey=' + dd_crop.h;

And make it readable like this:

myObj = new QueryString("http://codebehind.dk");
  myObj.w = 100;
  myObj.rx = 1000;
  myObj.ry = 1000;
  ...
  ...
  document.writeln(myObj.toLink("codebehind.dk"));
