Quick Reference

The onwheel event fires when the wheel of a pointing device is rolled up/down over an element, or the user scrolls/zooms on an element with a touchpad.

The onwheel event is supported by nearly all HTML tags.

				
					<!-- HTML -->
<div id="my_div" onwheel="my_function()"></div>
				
			
				
					// JavaScript
function my_function() {
    alert('Your mouse wheel was rolled.');
}

JavaScript

Any of the following are valid.

onwheel

				
					document.getElementById('my_div').onwheel = function() {my_function()};

function my_function() {
    alert('Your mouse wheel was rolled.');
}

wheel

				
					// method 1
document.getElementById('my_div').addEventListener('wheel', function() {
    alert('Your mouse wheel was rolled.');
});
				
			
				
					// method 2
document.getElementById('my_div').addEventListener('wheel', my_function);

function my_function() {
    alert('Your mouse wheel was rolled.');
}

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
