我正在尝试编写简化的javascript来运行a link中的特定示例。
我想要使用的示例是“展示”部分，其中标题“展示”淡入并显示图像。我希望提取相关的html和javascript来运行它。
我下载了示例文件并设法减少了不必要的html。

答案 0 :(得分：0)
您只需要JavaScript：
$(document).ready(function() {
var controller = $.superscrollorama();
// showcase tweens
controller.addTween('#showcase h1', TweenMax.from( $('#showcase h1'), .75, {css:{letterSpacing:20,opacity:0}, ease:Quad.easeOut}));
controller.addTween('#showcase p', TweenMax.from( $('#showcase p'), 1, {css:{opacity:0}, ease:Quad.easeOut}));
$('#showcase .gallery figure').css('position','relative').each(function() {
controller.addTween('#showcase .gallery', TweenMax.from( $(this), 1, {delay:Math.random()*.2,css:{left:Math.random()*200-100,top:Math.random()*200-100,opacity:0}, ease:Back.easeOut}));
});
});
