It's got style, it's got class —Devo, “Uncontrollable Urge" Effect Methods In this chapter, we'll closely examine each of the effect methods, revealing all of the mechanisms jQuery has for providing visual feedback to the user. Pre-Packaged Effects These methods allow us to quickly apply commonly used effects with a minimum configuration. .show() Displays the matched elements. .show([speed][, callback]) Parameters • speed (optional): A string or number determining how long the animation will run • callback (optional): A function to call once the animation is complete
Effect Methods Return Value The jQuery object, for chaining purposes. Description With no parameters, the .show() method is the simplest way to display an element: $('.target').show(); The matched elements will be revealed immediately, with no animation. This is roughly equivalent to calling .css('display', 'block'), except that the display property is restored to whatever it was initially. If an element is given a display value of inline, then it is hidden and shown, it will once again be displayed inline. When a speed is provided, .show() becomes an animation method. The .show() method animates the width, height, and opacity of the matched elements simultaneously. Speeds are given in millisecond durations of the animation; higher values indicate slower animations, not faster ones. The strings fast, normal, and slow can be supplied to indicate speed values of 200, 400, and 600 respectively. If the speed parameter is omitted, normal is assumed. If supplied, the callback is fired once the animation is complete. This can be useful for stringing different animations together in sequence. The callback is not sent any arguments, but this is set to the DOM element being animated. The callback is executed once per matched element, not once for the animation as a whole. We can animate any element, such as a simple containing an image: Trigger With the element initially hidden, we can show it slowly: $('.trigger').click(function() { $('.target').show('slow', function() { $(this).log('Effect complete.'); }); }); [ 132 ]
