用 javascript 探測當前網頁位置

假設現在我有個網頁,網址是:http://functionlab.org:80/tools/tcpproxy.php?user=FUNction#showscript
如果這網頁上有以下JavaScript 程式碼

<script type="text/javascript">
    //http://www.w3schools.com/htmldom/dom_obj_location.asp  
    document.write("location.href : "+location.href+"<br/>");
    document.write("location.protocol : "+location.protocol+"<br/>");
    document.write("location.hostname : "+location.hostname+"<br/>");
    document.write("location.host : "+location.host+"<br/>");
    document.write("location.port : "+location.port+"<br/>");
    document.write("location.pathname : "+location.pathname+"<br/>");
    document.write("location.search : "+location.search+"<br/>");
    document.write("location.hash : "+location.hash+"<br/>");
</javascript>

則該網頁上會顯示:
location.href : http://functionlab.org:80/tools/tcpproxy.php?user=FUNction#showscript
location.protocol : http
location.hostname : functionlab.org
location.host : functionlab.org:80
location.port : 80
location.pathname : /tools/tcpproxy.php
location.search : ?user=FUNction
location.hash : #showscript
