所以我一直在尝试按照本教程http://www.netmagazine.com/tutorials/getting-animations-trigger-right-time进行操作,并认识到这些效果仅适用于包含图像的元素。我想对不包含图像的元素(即:一块文本)产生这种影响,但无法使其工作。有没有人知道如何实现这一目标?谢谢你们!
这是脚本:
<script>
if (Modernizr.csstransitions) {
function preloadImages(imgs, callback) {
var cache = [],
imgsTotal = imgs.length,
imgsLoaded = 0;
$(imgs).each(function (i, img) {
var cacheImage = document.createElement('img');
cacheImage.onload = function () {
if (++imgsLoaded == imgsTotal) callback();
};
cacheImage.src = $(img).attr('src');
cache.push(cacheImage);
});
};
$.fn.trans = function () {
var t = arguments[0],
d = arguments[1] || '';
if (t) {
$.each(this, function (i, e) {
$(['-webkit-', '-moz-', '-o-', '-ms-', '']).each(function (i, p) {
$(e).css(p + 'transition' + d, t);
});
});
}
};
document.write('<link rel="stylesheet" href="animations.css" />');
$(function(){
//preload images contained within elements that need to animate
preloadImages($('.services img, .featured img'), function () {
$('.services, .featured').appear({
once: true,
forEachVisible: function (i, e) {
$(e).data('delay', i);
},
appear: function () {
var delay = 150,
stagger = 800,
sequential_delay = stagger * parseInt($(this).data('delay')) || 0;
$(this).children().each(function (i, e) {
$(e).trans(i * delay + sequential_delay + 'ms', '-delay');
});
$(this).removeClass('animationBegin');
}
});
});
});
}
</script>

你可以找到处理视口css3动画的轻量级jQuery滚动脚本 SEE HERE
我创建了一个演示如何工作的演示,滚动小提琴,当元素在视口中时你会看到动画。
