<!-- 0.修改 VIEW->Template(关键字替换)，增加 template id -->

//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'},
{img:4,h1:'Insercure',h2:'HUSSLER'},
{img:5,h1:'LOving',h2:'REBRL'},
{img:6,h1:'Passionate',h2:'SEEKER'},
{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
.replace(/^\s*/,'')

//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
var main = g('main_'+n);
var ctrl = g('ctrl_'+n);
//5.2 获得所有的幻灯片以及控制按钮

}
//5.4 为当前控制按钮和幻灯片添加附加样式
main.className += ' main-i_active';

//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)
}
