简要教程
Karrot Slider是一款纯Javascript和CSS3制作的自动播放的幻灯片插件。该幻灯片没有任何外部依赖,内置有8种不同的动画过渡效果。该幻灯片支持响应式图片设计模式,也可以制作为全屏幻灯片模式。
使用方法
使用该幻灯片插件需要引入slider.css和sliderEffects.js文件。
<link href="css/slider.css?7.1.33" rel="stylesheet" type="text/css" /> <script src="js/sliderEffects.js?7.1.33"></script>
复制代码
HTML结构 创建一个带ID号的<p>,然后设置它的宽度和高度,并将第一张图片放置在这个<p>中。 <p id="slider" style="width: 900px; height: 505px; margin: auto;"> <img src="images/1.jpg" > </p>
复制代码
8种内置过渡动画效果的使用 该幻灯片内置了8种不同的动画过渡效果: Dissolve Slide Up Slide Down Slide Left Slide Right Mosaic Window Doors 所有的效果函数都包含2个参数,第一个是当前图片的引用,第二个是下一张图片的引用。 //effect(current, next); KSDissolve("images/1.jpg", "images/2.jpg"); KSSlideUp("images/1.jpg", "images/2.jpg"); KSSlideDown("images/1.jpg", "images/2.jpg"); KSSlideLeft("images/1.jpg", "images/2.jpg"); KSSlideRight("images/1.jpg", "images/2.jpg"); KSMosaic("images/1.jpg", "images/2.jpg"); KSWindows("images/1.jpg", "images/2.jpg"); KSDoors("images/1.jpg", "images/2.jpg");
复制代码
初始化插件 要初始化该幻灯片插件,可以创建3个变量:一个图片数组,图片显示的时间和当前图片的下标。 var images = ["images/1.jpg" , "images/2.jpg" , "images/3.jpg", "images/4.jpg" ]; var timing = 3000; var currentImg = 1;
复制代码
然后创建一个函数来选择下一张图片,并可以设置过渡到下一张图片时的动画效果。 function karrotSlider() { var nextimg = (currentImg + 1) > images.length ? 1 : currentImg + 1 ; var effect = Math.floor (Math.random()*6 +1 ); switch (effect) { case 1: KSDissolve(images[currentImg- 1], images[nextimg- 1]) break; case 2: KSSlideUp(images[currentImg- 1], images[nextimg- 1]) break; case 3: KSSlideDown(images[currentImg- 1], images[nextimg- 1]) break; case 4: KSSlideLeft(images[currentImg- 1], images[nextimg- 1]) break; case 5: KSSlideRight(images[currentImg- 1], images[nextimg- 1]) break; case 6: KSMosaic(images[currentImg- 1], images[nextimg- 1]) break; case 7: KSWindows(images[currentImg- 1], images[nextimg- 1]) break; case 8: KSDoors(images[currentImg- 1], images[nextimg- 1]) break; } currentImg = (currentImg + 1) > images.length ? 1 : currentImg + 1; }
复制代码
最后使用setInterval()函数来调用这个函数。 setInterval(function () { karrotSlider() } , timing);
注意:所有的图片必须尺寸相同。如果想制作全屏幻灯片,可以在body结束之前调用fullScreen();函数。

The core features of HTML5 include semantic tags, multimedia support, offline storage and local storage, and form enhancement. 1. Semantic tags such as, etc. to improve code readability and SEO effect. 2. Simplify multimedia embedding with labels. 3.
