Bug 8322: Add plain object signature to DOM manipulation methods

[timmywil]

This will allow calls to append/prepend such as

$('div').append('<div/>', { id: "foo", class: "bar" });

I've added tests, but I'm not sure those are the best places. However, I feel I had to add new ones. I don't think I can integrate my tests into the common ones because bareObj and functionReturningObj only take one argument. Any review is appreciated.

can you update the perf test to reflect 18408f4? thx!

[timmywil]

It already is. I added the test when I added that commit. Compare with first revision at http://jsperf.com/dh-dommanip-with-8322-patch . The updated perf tests need more tests tho.

[leeoniya]

nvm, my bad. the performance gap is 50%-60% on first run and 10%-20% on reruns (diminishing with each rerun) :( jQuery.isPlainObject must be pretty slow. would be be nice to just rely on args.length, hehe.

[timmywil]

It's strange to me that the first revision tests are that much slower even though it never hits the isPlainObject check. However, it sped up when I checked args[1] rather than checking length first. I created more tests to be sure.

This was not accepted. Closing.
