Create DOM Click Event In JavaScript
To demonstrate, DOM event and styling with JavaScript, a new window will be opened in a new web browser window or tab.
Multiple windows can be opened and reused assuming that JavaScript is not disabled. JavaScript can be used to create events, inline styles or a internal or external styles.
JavaScript open() method can take optional parameters for the name, URL and window dimensions. Inline style attributes are inside HTML elements, Internal styles use a style element. The DOM event for this tutorial is the click method. External Event styles use the link element in the head section on an HTML document.
