This command returns a single HTML or XML element with the given id. This means it is actually a shortcut for document.querySelector().

If the JavaScript on the page already defines $ for something else (like e.g. jQuery does), it will not be overwritten by this command.

Syntax[edit]

$(selector)

Parameters[edit]

selector[edit]

Selector used to match the element to return. This follows the syntax of document.querySelector(). (required)

Examples[edit]

$("#element")

This returns the element with the id element.
