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

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

$(id)

Parameters

id

Id of the element to return. (required)

Examples

$("element")

This returns the element with the id element.
