//1.数据定义（实际生产环境中应由后台给出）
var data = [

{img:4,h1:'Insecure',h2:'HUSSLER'},
{img:5,h1:'Loving',h2:'REBEL'},
{img:6,h1:'Crazy',h2:'FRIEND'}
];
//2.定义通用函数
var g = function(id){
if(id.substr(0,1) == '.'){ //通过classname获取
return document.getElementsByClassName(id.substr(1));

return document.getElementById(id);

//3.天假幻灯片操作（所有幻灯片对应的按钮）

//3.1获取到所有幻灯片母版
var tpl_main = g('template_main').innerHTML

}
//3.4把html回写到对应的DOM中
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
var main = g('main_' +n);
var ctrl = g('ctrl_' +n);
//5.2获得所有幻灯片及他们的控制按钮
var clear_main = g('.main-i');
var clear_ctrl = g('.ctrl-i');
//5.3清除获取到的内容的active样式

.replace(' ctrl-i_active', '');
}
//5.4为当前的控制按钮和幻灯片附加样式
main.className += ' main-i_active';

}
//6.定义合适处理幻灯片输出
window.onload = function(){
addSliders();
switchSlider(2)
}
