js获取url页面id，也就是最后的数字文件名

<script>
var strUrl = "//.jb51./article/825.htm";
url = strUrl.match(/\/(\d)\.(html|htm|shtm|shtml)/);
document.write(url[1]);
</script>

<script>
var strUrl = location.href;
url = strUrl.match(/\/(\d)\.(html|htm|shtm|shtml)/);
document.write(url[1]);
</script>

<script>
var strUrl = location.href;
var arrUrl=strUrl.split("/");
var strPage=arrUrl[arrUrl.length-1];
alert(strPage.replace(".html","").replace(".htm",""));
</script>

<script>
var strUrl = window.location.href;
str=strUrl.substring(strUrl.lastIndexOf("/") + 1)
alert(str.replace(".html","").replace(".htm",""));
</script>

<script>
var strUrl = "http://.jb1./article/222.htm";
//获取当前页面名称
//var strUrl=window.location.href;
var arrUrl=strUrl.split("/");
var strPage=arrUrl[arrUrl.length-1];
if(strPage.indexOf("?")>-1){
  var pageName=strPage.split("?");
  strPage=pageName[0];
}
alert(strPage.replace("html","").replace(".htm",""));
</script>
