There are a lot of questions about whether or not finding an element is faster via class or id or some other selector. I’m not interested in that. I want to know if you have:
var link = $ (this); //let's say you're in a click handler
Is it faster to find the container by doing
var container = link.closest('.container'); //assume container is .container
or
var container = $ ('#mycontainer'); //assume same element as above
I’m asking this question not just for the particular scenario above (ok, well, yes, for this scenario too) but for cached traversal vs. creating a fresh jQuery object that has an ID. I notice in a lot of my code I tend to do the former method (since it can lend itself to being more dynamic), but I was always curious if it was faster to do it the latter way.
Thanks
