How JQuery selectors work -


this question has answer here:

i new jquery. learned jquery selector, used selecting dom elements. dont understand how internally finds dom element. if give $("#pelement") or $(".pclass") how jquery finds dom element ? use document.getelementbyid() or ? please me understand. lot.

it's library, yes, if id you're looking for, uses document.getelementbyid()

if queryselector() available in browser, uses that, otherwise uses getelementsbyclassname() classes.

in other words takes ever available in browser , uses efficient one, , abstracts can use css selectors in code without having think stuff browser supports, , method use etc.
