I've been working with selection/range objects, and because to the incredible amount of inconsistencies between browsers for specific selection/range stuff (even more than the DOM) I was wondering if there was a framework that would help me get through them.

fieldselection is a very usable jquery plugin for selection/range manipulation.

Only works for textareas and inputs though.

Take a look at IERange:
IERange is a feature-complete implementation of W3C DOM Ranges for Internet Explorer, allowing users to write one cross-browser version of their range manipulation code.
Supports Range APIs:
document.createRange()startContainer,startOffset,endContainer,endOffset,commonAncestorContainer,collapsedsetStart(),setEnd(),setStartBefore(),setStartAfter(),setEndBefore(),setEndAfter(),selectNode(),selectNodeContents(),collapse()insertNode(),surroundContents()extractContents(),cloneContents(),deleteContents()compareBoundaryPoints(),cloneRange(),createContextualFragment(),toString()
Supports Selection APIs:
- Range support (Webkit-style)
window.getSelection()addRange(),removeAllRanges(),getRangeAt(),toString()

IERange's biggest strength is its algorithms for expressing a `TextRange` in terms of nodes and offsets (as a Range does) and converting such and object back into a `TextRange`. However, it cannot fully abstract away the differences between the two: for example, the underlying `TextRange` will change in response to changes in the DOM while the `IERange` built upon it will not reflect these changes. There are also discrepancies between how the user selection is represented as a Range, which are down to the browser. [continued]

Also note that creating an `IERange` is hugely slower than getting a DOM Range in other browsers. None of these are the library's fault; it's simply the nature of the problem. In short, best use with care and knowledge of the abstraction `IERange` represents.

I've written a new range/selection library called Rangy that is similar in concept to IERange but goes quite a lot further. The core is pretty much complete and currently available to download. I'm currently bugfixing and documenting it and it should be only be a few weeks before a full release.

Thanks for your great work on Rangy Tim Down. I'm using your lib in my new project and already have send you a bug report. I think it would be a good idea to create a mailing list, so that it is possible to discuss issues/features and suggest new features (maybe with a patch). Eg., I'm currently trying to get a startOffset and endOffset for the commonAncestorContainer rather than start/end containers. This would be a helpful feature I believe.
