js获取当前路径的简单示例代码

<script type="text/javascript">   
thisURL = document.URL;
thisHREF = document.location.href;
thisSLoc = self.location.href;
thisDLoc = document.location;
strwrite = " thisURL: [" + thisURL + "]<br />"
strwrite += " thisHREF: [" + thisHREF + "]<br />"
strwrite += " thisSLoc: [" + thisSLoc + "]<br />"
strwrite += " thisDLoc: [" + thisDLoc + "]<br />"
document.write( strwrite );

thisTLoc = top.location.href;
thisPLoc = parent.document.location;
thisTHost = top.location.hostname;
thisHost = location.hostname;
strwrite = " thisTLoc: [" + thisTLoc + "]<br />"
strwrite += " thisPLoc: [" + thisPLoc + "]<br />"
strwrite += " thisTHost: [" + thisTHost + "]<br />"
strwrite += " thisHost: [" + thisHost + "]<br />"
document.write( strwrite );

tmpHPage = thisHREF.split( "/" );
thisHPage = tmpHPage[ tmpHPage.length-1 ];
tmpUPage = thisURL.split( "/" );
thisUPage = tmpUPage[ tmpUPage.length-1 ];
strwrite = " thisHPage: [" + thisHPage + "]<br />"
strwrite += " thisUPage: [" + thisUPage + "]<br />"
document.write( strwrite );
var url="<%=request.getRequestURI()%>";
alert(url)
</script>

request.getRequestURI();
request.getRequestURL();
request.getQueryString();

request.getServletPath()

可以得到自己的网络地址：request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+request.getRequestURI()
