What are Selectors in jQuery?

Posted by Prem Tiwari | Updated on

A jQuery Selector is a function that uses the expressions to find out matching elements from a DOM based on the given criteria. In a simple language, selectors are used to select one or more HTML elements using jQuery. Once an element is selected then we can perform various operations on that selected element.

Selecting an element in DOM is done with the help of $() construct with a string parameter containing any CSS selector expression. $() will return zero or more DOM elements on which you can apply any effect or style.
