//1.数据定义（实际生产环境中，应有后台给出）
var data = [
{img:1,h1:'Creative',h2:'UUET'},
{img:2,h1:'Friendly',h2:'DEVIL'},
{img:3,h1:'Tranquilent',h2:'COMPATRIOT'},

// 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.添加幻灯片的操作（所有幻灯片&对应的按钮）
function addSliders(){
//3.1获取模板
var tpl_main = g('template_main').innerHTML
.replace(/^\s*/,'')
.replace(/\s*$/,'');
var tpl_ctrl = g('template_ctrl').innerHTML

//5.1获得要展现的幻灯片&控制按钮 DOM

//6.动态调整图片的 margin-top 使其垂直居中
function movePictures(){
var pictures = g('.picture');
for(i=0;i<pictures.length;i++){
pictures[i].style.marginTop = (-1 * pictures[i].clientHeight/2) + 'px'
}

//4.定义合适处理幻灯片输出
window.onload = function(){
addSliders();
switchSlider(1);
setTimeout(function(){
movePictures();
},100)
}
