IE6里改变ifram重新加载

window.parent.ifrm1.document.body.innerHTML="<span style='font-size:16'><b>正在检索新书目录,请稍候。。。</span>";
        
         var urlPath="window.parent.ifrm1.location='../../xinshuDirectoryAction.do?method=search"+encodeURI(url)+"'";
        setTimeout(urlPath, 1);//使用延时解决IE进度条loading状态问题
