<script type="text/javascript">
//1.数据定义（实际生产环境中，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:'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.添加幻灯片操作（所有幻灯片对应的按钮）
function addSlider(){
//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*/,'')

//3.2 定义最终输出HTML的变量
var out_main = [];
var out_ctrl = [];

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('');
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
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
var clear_main = g('.main-i');
var clear_ctrl = g('.ctrl-i');
//5.3清除他们的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 定义何时处理幻灯片输出
window.onload = function(){
addSlider();
switchSlider(1);
}
</script>
