What the question says...
Does jQuery have any methods that will allow you to query a mult-dimensional array of objects in a similar fashion as it does with the DOM.
You may find a plugin, but not in the jQuery core. There are a few helpful array methods: each
, unique
, inArray
. In combination, you could create something custom to meet your needs.
What you are searching for is more of a set library with xpath like traversal. Prototype has a much larger set of array methods. But still probably wouldn't meet your exact needs out of the box.
I agree with alex, such a library/extension would be interesting.
