2 Fading Animations In this chapter we'll be looking at the most basic types of jQuery animations, in which the element being animated gradually appears or disappears. There are several jQuery methods that deal with fading and we'll look at each of them in turn throughout the chapter. These methods are: fadeIn() fadeOut() fadeTo() fadeToggle() show() hide() toggle() In this chapter, we will learn: How to create simple animations with the fadeIn(), fadeOut(), and fadeToggle() methods How to control the ending opacity value of the animation with the fadeTo() method How to create fading animations with the show() and hide() methods How to simplify our code with the toggle() methods
Fading Animations Fading animations The fadeIn() and fadeOut() methods perform the least complex animations available via jQuery. They simply adjust the opacity of selected elements to either show or hide the element, and can be used with no additional configuration. The fadeToggle() method is almost as simple, but does provide some basic logic to check the selected element's current state. Elements that are hidden with display:none will be set to their correct display type, (either display:block for block-level elements or display:inline for inline elements) where possible at the start of a fadeIn() animation. An element's natural display type is used wherever possible, so hidden elements are set to display:list-item, and hidden elements are set to display:table-cell. IE however, has been known to have issues fading elements. In IE8 (and lower) for example, the is shown immediately when the fadeIn() method is used, even with a large duration. Elements that are set to display:block (or are set to another display type but nevertheless visible on the page) will be set to display:none at the end of a fadeOut() animation. Elements will switch between their visible and non-visible states when the fadeToggle() method is used. Elements that are to be shown using the fadeIn() method must be initially hidden with display:none; while elements that are hidden with visibility:hidden; for example, will remain hidden at the end of the animation. In their simplest forms, these methods can be used without any additional configuration. We can simply call the methods on any collection of selected elements without using any arguments: jQuery(elements).fadeIn(); jQuery(elements).fadeOut(); jquery(elements).fadeToggle(); When no arguments are provided, the animations will have the default duration of 400 milliseconds and the default easing of swing. Configuring the animations with arguments With arguments, the fading methods may take the following form, (square brackets denote optional arguments): jQuery(elements).fadeIn([duration], [easing], [callback]); jQuery(elements).fadeOut([duration], [easing], [callback]); jQuery(elements).fadeToggle([duration], [easing], [callback); [ 20 ]
