Difference between :input and input in Jquery

Question

On some tutorials, I've seen these selectors:

$(':input');

or

$('input');

Note the ':'.

Are there any differences?

Answer 1

$('input') = with only the element name, selects only HTML elements.

$(':input') = with the colon, selects/filter all form input type elements, including input, select, textarea, and button elements.

Refer to the jQuery selector information:
