2013年过去了，各门户网站纷纷对上一年的大事记进行了盘点，百度百科当然不能缺席，其制作的“百度百科——年终盘点”专题，列举了科技、人物、社会和网络四个方面在2013年从1月到12月各个月的大事、趣事、乐事等等，让我们很好的回顾过去一年某个时刻发生的事情。等等，我们今天要说的并不是这个专题的内容，而是页面效果。这个专题采用了全屏制作，每屏的热词都以从四面飞往屏幕中间，效果非常不错。今天我们使用上次介绍的 jQuery 全屏滚动插件 fullPage.js 制作一个类似的效果。
fullPage.js 提供丰富的回调函数，让我们能都在各个阶段进行控制，制作这个专题的中的动画效果就需要用到这些回调函数。
制作方法
1、HTML
我们在每屏里面放一个 div，用于放背景图片，然后把热词和图片放在这个 div 里面，如：
<div class="section"> <div class="science-inner inner"> <a class="itemshow stiteml st1" href="https://www.dowebok.com/javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >网络机顶盒</a> <a class="itemshow stiteml st2" href="https://www.dowebok.com/javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >干细胞人造肉</a> <a class="itemshow stiteml st3" href="https://www.dowebok.com/javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >3D涂鸦笔</a> <a class="itemshow stiteml st4" href="https://www.dowebok.com/javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >H7N9</a> <a class="stimg1" href="https://www.dowebok.com/javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" > <img width="181" height="166" src="https://www.dowebok.com/images/h7n9.jpg"> </a> </div> </div>
我们在热词和图片中加一个 rel 属性，里面放4个数值，用逗号隔开，这4个数值的作用是用于定位，前两个是默认的位置，后两个是出现后的位置。添加之后代码如下：
<div class="section"> <div class="science-inner inner"> <a class="itemshow stiteml st1" href="https://www.dowebok.com/javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="0,-350,0,7">网络机顶盒</a> <a class="itemshow stiteml st2" href="https://www.dowebok.com/javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="0,-350,0,37">干细胞人造肉</a> <a class="itemshow stiteml st3" href="https://www.dowebok.com/javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="0,-350,0,68">3D涂鸦笔</a> <a class="itemshow stiteml st4" href="https://www.dowebok.com/javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="0,-350,0,88">H7N9</a> <a class="stimg1" href="https://www.dowebok.com/javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="0,-350,0,153"> <img width="181" height="166" src="https://www.dowebok.com/images/h7n9.jpg"> </a> </div> </div>
2、CSS
CSS 主要是热词旁边“1月、2月”背景图片的定位，如：
.science-inner .st1 {
background-position: 0 4px
}
.science-inner .st2 {
background-position: 0 -59px
}
.science-inner .st3 {
background-position: 0 -59px
}
.science-inner .st4 {
font-size: 48px;
background-position: 0 -104px
}
3、JavaScript
3.1、首先设置一些基本的效果，比如背景颜色、锚链接、绑定菜单等等；
$(document).ready(function() {
$.fn.fullpage({
slidesColor: ['#0075D1', '#C2E5FF', '#FDF6E1', '#E9E9E9', '#F3F3F3', '#F9F3DC'],
anchors: ['page1', 'page2', 'page3', 'page4', 'page5', 'page6'],
menu: '#menu'
});
});
3.2、初始化后的回调函数，或者笼统的说是页面加载后的回调函数，本例是“史记”两个字的动画效果；
afterRender: function(){
$('.screen-main span').each(function(){
var $rel = $(this).attr('rel');
var $arr = $rel.split(',');
$(this).animate({
left: $arr[2] + 'px',
top: $arr[3] + 'px'
}, 500);
});
$('.inner a').each(function(){
var $rel = $(this).attr('rel');
var $arr = $rel.split(',');
$(this).animate({
left: $arr[0] + 'px',
top: $arr[1] + 'px'
}, 500);
});
}
3.3、滚动前后的回调函数，本例是热词很多图片的动画效果；
afterLoad: function(anchorLink, index){
if(index == 1){
$('.screen-main span').each(function(){
var $rel = $(this).attr('rel');
var $arr = $rel.split(',');
$(this).animate({
left: $arr[2] + 'px',
top: $arr[3] + 'px'
}, 500);
});
}
if(index == 2 || index == 3 || index == 4 || index == 5){
$('.inner').eq(index - 2).find('a').each(function(){
var $rel = $(this).attr('rel');
var $arr = $rel.split(',');
$(this).animate({
left: $arr[2] + 'px',
top: $arr[3] + 'px'
}, 500);
});
}
if(index == 6){
$('.zanzhu-con a').fadeIn(1000);
}
},
onLeave: function(index, direction){
if(index == 1){
$('.screen-main span').each(function(){
var $rel = $(this).attr('rel');
var $arr = $rel.split(',');
$(this).animate({
left: $arr[0] + 'px',
top: $arr[1] + 'px'
}, 500);
});
}
if(index == 2 || index == 3 || index == 4 || index == 5){
$('.inner').eq(index - 2).find('a').each(function(){
var $rel = $(this).attr('rel');
var $arr = $rel.split(',');
$(this).animate({
left: $arr[0] + 'px',
top: $arr[1] + 'px'
}, 500);
});
}
if(index == 6){
$('.zanzhu-con a').fadeOut(1000);
}
}
到这就完成了，大家还可以举一反三，编写出其他动画效果以及应用到其他地方。
