$.prev("div.a").find('.b').
$.prev("div.a .b").
One works and the other does not. What’s the difference?
$.prev(div.a).find(‘.b’). $.prev(div.a .b). One works and the other does not. What’s the difference?

Well, the selector works, it just doesn’t give you what you want:
According to jQuery Docs
.prev([expr]):This means:
$(elem).prev("div.a").find('.b')is looking for any previous sibling in the DOM Tree that is adiv.aand returning the first – then search within that element using.find()for a.bWhereas:
$(elem).prev("div.a .b")is looking for any previous sibling that is adiv.a .band returning the first.They are not equivalent and therefore return different results.
