Resizable containment option

[dgouldin]

Add a containment option to resizable with the same behavior as the drggable containment option.

Hi!

I think your enhancement is great. However, there are problems, if one of the resizeable's parent nodes is positioned relative or absolute. In that case the left and top offsets of these parent nodes must be subtracted from the left- and top-value that will be used for the containment calculations (i.e. the first to elements of options.containment ).

If the parentNode itsself is positioned relative or absolute everything's quite easy, then options.containment should just look like (around line 65):

  			options.containment = [
  				0,
  				0,
  				(ce.offsetWidth || ce.scrollWidth),
  				(ce.offsetHeight || ce.scrollHeight)
  			];

However if one of the other parent nodes are positioned things get more difficult I guess.

At the moment I have no really good idea how to fix this properly...

Thanks anyways.

Updated resizable containment implementation

Thanks for the suggestion. I took some more inspiration from draggable and am now taking parent node offsets into account. I think this solves the issue you were referring to.
