Quick Reference

The onbeforeprint event fires when a page is about to start printing or the dialogue box appears.

Supported HTML tags:

				
					<!-- HTML -->
<body onbeforeprint="my_function()">
				
			
				
					// JavaScript
function my_function() {
    alert('Your document is about to be printed.');
}

JavaScript

Both of the following are valid.

onbeforeprint

				
					document.getElementsByTagName('body')[0].onbeforeprint = function() {my_function()};

function my_function() {
    alert('Your document is about to be printed.');
}

beforeprint

				
					window.addEventListener('beforeprint', function() {
  	alert('Your document is about to be printed.');
});

We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.

HTML NOTES:

  • In our HTML section the term “tag” and “element” are often used interchangeably to refer to both the tag used to create a page element and the element created by the tag (p tag = p element = paragraph on the page)
  • HTML5 is not case sensitive; so P is the same as p, H1 is the same as h1
  • Global attributes can be used with all HTML tags and are therefore not mentioned on every tag page
  • To write clean, readable HTML code, it is best to use indentation whereas elements within elements are indented (tabbed or spaces) to create something that looks like a project outline
  • The browser will automatically remove any extra spaces and lines in your HTML code when the page is displayed
  • Double quotes or single quotes can be used around HTML attribute values, but when the attribute value itself contains one form of quote, it will be necessary to use the other around the attribute
