<script type="text/javascript">
//1.数据定义（实际环境中应由后台给出）
var data = [
{img:1,h1:'Creative',h2:'DUET'},
{img:2,h1:'Friendly',h2:'DEVIL'},
{img:3,h1:'Tranquilent',h2:'COMPATRIOT'},
{img:4,h1:'Insecure',h2:'HUSSLER'},
{img:5,h1:'Loving',h2:'REBEL'},
{img:6,h1:'Passionate',h2:'REBEL'},
{img:7,h1:'Crazy',h2:'FRIEND'}
];

//2.通用函数
var g = function(id) {
if (id.substr(0, 1) == '.') {
return document.getElementsByClassName(id.substr(1));
}
return document.getElementById(id);
};
//3.添加幻灯片
function addSliders() {
//3.1获取模版
var tpl_main = g('template_main').innerHTML
.replace(/^\s*/, '')
.replace(/\s*$/, '');
var tpl_ctrl = g('template_ctrl').innerHTML
.replace(/^\s*/, '')
.replace(/\s*$/, '');
//3.2定义最终输出html的变量
var out_main = [];
var out_ctrl = [];
//3.3遍历所有数据，构建最终输出的html
for( var i=0; i<data.length;i++ ) {
var _html_main = tpl_main

}
//3.4把html回写到对应的dom里
g('template_main').innerHTML = out_main.join(' ');
g('template_ctrl').innerHTML = out_ctrl.join(' ');
}
//5.幻灯片切换
function switchSlider(n){
//5.1获得要展现的幻灯片和控制按钮dom
var main = g('main_'+n);
var ctrl = g('ctrl_'+n);
//5.2获得所有幻灯片以及控制按钮
var clear_main = g('.main-i');
var clear_ctrl = g('.ctrl-i');
//5.3清楚他们的active样式
for(var i=0; i<clear_ctrl.length;i++) {
clear_main[i].className = clear_main[i].className
.replace('main-i_active', ' ');
clear_ctrl[i].className = clear_ctrl[i].className
.replace('ctrl-i_active', ' ');
}
//5.4为当前控制按钮和幻灯片附加样式
main.className += 'main-i_active';
ctrl.className += 'ctrl-i_active';
}
//4.何时处理幻灯片输出
window.onload = function () {
addSliders();
switchSlider(1);
}

//1 数据定义（实际开发过程中由后台做）

{img:3,h2:'Creative',h3:'DUET'},
{img:4,h2:'Creative',h3:'DUET'},
{img:5,h2:'Creative',h3:'DUET'},
{img:6,h2:'Creative',h3:'DUET'},
{img:7,h2:'Creative',h3:'DUET'}
];

//2 定义通用函数
var g = function(id){
// id的第一个字符为.(实际传入的是类名)
if(id.substr(0,1) == '.'){
return document.getElementsByClassName(id.substr(1));
}
return document.getElementById(id);
}

// 3添加幻灯片的操作(所有的幻灯片及其按钮)
function addSliders(){
// 3.1 获取模板（模板template_main内所有的内容，包括空行和html）
var tpl_main = g('template_main').innerHTML

for (var i = 0; i < data.length; i++) {

out_main.push(_html_main);
out_ctrl.push(_html_ctrl);
};

// 3.4把html回写到对应的DOM里面
g('template_main').innerHTML = out_main.join('');//join('')是为了输出格式好看
g('template_ctrl').innerHTML = out_ctrl.join('');

};
// 5 幻灯片切换
function switchSlider(n){
// 5.1 获得要展现的幻灯片&控制按钮 DOM 通过id
var main = g('main_'+n);
var ctrl = g('ctrl_'+n);

// 5.2删除其他幻灯片和按钮的切换样式
// 获得全部幻灯片和按钮(通过类名)
var clear_main = g('.main-i');
var clear_ctrl = g('.ctrl-i');
for (var i = 0; i < clear_main.length; i++) {

};
for (var i = 0; i < clear_ctrl.length; i++) {
clear_ctrl[i].className = clear_ctrl[i].className.replace(' ctrl-i-active','');
};

// 5.3 为当前幻灯片和按钮添加样式
// console.log(main);
main.className += ' main-i-active';
ctrl.className += ' ctrl-i-active';

}

// 6 动态调整图片的margin-top 以使其垂直居中
function movePictures(){
var pictures = g('.picture');
for (var i = 0; i < pictures.length; i++) {
pictures[i].style.marginTop = -(pictures[i].clientHeight/2) +'px';
};
}

// 4 定义页面元素加载完成后处理幻灯片输出
window.onload = function(){
addSliders();
switchSlider(1);
setTimeout(function(){
movePictures();
}, 100);
}

</script>
</body>
</html>

最后一块的背景图片的优化没写，凑合看吧
