Selector in JQuery

JQuery Selectors are one of the most important part of a Jquery statement. They allow us to select particular element from the web page and perform some kind of action on them. This selection may be based on CSS selectors or based on their own custom selectors.

All the selectors are represented by $ followed by parenthesis, $().

$(selector).action(), where

• $ is for representing it as a jQuery.

• selector represents the HTML element to be selected.

• action() represents the kind of action we perform on the selected element.
