[jQuery] Plugin, passing user defined default selector not working

[Nic Hubbard]

I have a small plugin that creates an iframe, and lets links open
within the iframe.  The default is to append the iframe to the body,
but I wanted the user to be able to pass in an ID and have the iframe
append to that.  Sounded easy enough, but it is not working for some
reason.

  $.fn.testFrame = function(options) {
    var defaults = {
      urlSuffix: '',
      iframe: 'body'
    };

    $(defaults.iframe).append('<iframe name="assetEditFrame"
id="assetEditFrame" scrolling="no" frameborder="0"></iframe>');

    var options = $.extend(defaults, options);

    return this.each(function() {

      var obj = $(this);
      var itemId = obj.attr('id');
      var itemHref = obj.attr('href');

      obj.attr('target', 'assetEditFrame');
      obj.attr('href', itemHref + defaults.urlSuffix);
    });
  };


Everytime I add $('p').testFrame({iframe: '#content'}); it won't pass
#content, and allow the iframe to be created there, it just uses the
default each time.  Have I done this incorrectly?
