Different of input start with colon and without colon

Question

What is the different between

$("input[name='ABC']") // without ":"
$(":input[name='ABC']") // with ":"

both work same to me, so should we write it with colon ":" or without? which is more correct?

Answer 1

input will just select specifically the <input> element.

:input selects <input>, <textarea>, <select>, and <button>.
