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.

Contents

Parameters

selector

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