我想动态改变网页中pdf的路径，网页能捕捉到新路径，但是好像总是加载不上，浏览器假死状态。。求解
码如下多谢多谢function getPdf()
{ var args=GetUrlParms();
document.getElementById("pdfPlus").src="items/"+args['filename']+".pdf";
//document.write("items/"+args['filename']+".pdf");
}function GetUrlParms()
{
var args=new Object();
var query=location.search.substring(1);//获取查询串
var pairs=query.split("&");//在逗号处断开
for(var i=0;i<pairs.length;i++)
{
var pos=pairs[i].indexOf('=');//查找name=value
if(pos==-1) continue;//如果没有找到就跳过
var argname=pairs[i].substring(0,pos);//提取name
var value=pairs[i].substring(pos+1);//提取value
args[argname]=unescape(value);//存为属性
}
return args;
}
<body onload="getPdf()">
<object classid="clsid:CA8A9780-280D-11CF-A24D-444553540000" width="760" height="600" border="0" id="pdfPlus">
<param name="SRC" value="items/Cold.pdf">

<param name="_ExtentX" value="20108">
<param name="_ExtentY" value="10866">
