1.在网页加上按钮引导进入子页面
<li>
<a class="J_menuItem" href="pdf.html?pdfname=pdf/1.1.pdf">1.1</a>
</li>用 ？ XXX= aaaa 来传递参数 XXX
2.用getQueryVariable函数，获取参数
function getQueryVariable(variable)
{
var query = window.location.search.substring(1);
var vars = query.split("&");
for (var i=0;i<vars.length;i++) {
var pair = vars[i].split("=");
if(pair[0] == variable){return pair[1];}
}
return(false);
}可以用alter来建议是否正确获取到参数
alter(getQueryVariable("pdfname"))3.动态加载src
iframe.src = getQueryVariable("pdfname")+"#view=FitH,top"根据iframe id 来加载src
4.适配chrome浏览器 自适应页面大小
接入参数#view=FitH,top
src ="pdf/aa.html#view=FitH,top"5.整体页面demo
