为什么只有标题会出现而图标不会出现了呢？
这是我的代码：
@charset "utf-8";
*{
margin:0;
border:0;
padding:0;
}
body{
padding:50px 0;
background-color:#fff;
font-size:14px;

display:-moz-box;/*适应fire-fox*/
display:box;/*适应其他浏览器除ie*/

js 的
//1.数据定义（实际环境应有后台给出）
var data = [
{img:1,h1:'lllllla',h2:'1113212'},
{img:2,h1:'lllllls',h2:'111321212'},
{img:3,h1:'lllllld',h2:'111212'},
{img:4,h1:'llllllf',h2:'1113212'},
{img:5,h1:'llllllx',h2:'11131212'},
{img:6,h1:'lllllls',h2:'11112'},
{img:7,h1:'lllllla',h2:'1113212'}
];
//2.定义通用函数
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（所有幻灯片和按钮）
function addSliders(){
//3.1 获取模板
var tpl_main = g('template_main').innerHTML
.replace(/^\s*/,'')
.replace(/\s*$/,'');
var tpl_ctrl = g('template_ctrl').innerHTML //控制按钮的模板
.replace(/^\s*/,'')
.replace(/\s*$/,'');
//3.2定义最终输出HTML 的变量
var out_main = [];//输出所有幻灯片
var out_ctrl = [];//输出所有控制按钮
//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.replace(/{{index}}/g,data[i].img).replace(/{{h2}}/g,data[i].h1).replace(/{{h3}}/g,data[i].h2);
//替换临时变量，g表示全局替换
var _html_ctrl = tpl_ctrl.replace(/{{index}}/g,data[i].img);
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('');//所有幻灯片
g('template_ctrl').innerHTML = out_ctrl.join('');//所有控制按钮
}
//4.定义何时出理 当窗口打开的时候再添加灯片
window.onload = function(){
addSliders();
//switchSlider(1);
}
