JavaScript How To part 1

Writing to The HTML Document

The example below writes a

element with current date information to the HTML document:

Note: Try to avoid using document.write() in real life JavaScript code. The entire HTML page will be overwritten if document.write() is used inside a function, or after the page is loaded. However, document.write() is an easy way to demonstrate JavaScript output in a tutorial.

Changing HTML Elements

The example below writes the current date into an existing

element:

Note: To manipulate HTML elements JavaScript uses the DOM method getElementById(). This method accesses the element with the specified id.
