Javascript 取得目前網址 相關資訊

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

view plaincopy to clipboardprint?

1. <script type="text/javascript">  
2. //http://www.w3schools.com/htmldom/dom_obj_location.asp  
3. document.write("location.href ： "+location.href+"<br/>");  
4. document.write("location.protocol ： "+location.protocol+"<br/>");  
5. document.write("location.hostname ： "+location.hostname+"<br/>");  
6. document.write("location.host ： "+location.host+"<br/>");  
7. document.write("location.port ： "+location.port+"<br/>");  
8. document.write("location.pathname ： "+location.pathname+"<br/>");  
9. document.write("location.search ： "+location.search+"<br/>");  
10. document.write("location.hash ： "+location.hash+"<br/>");  
11. </script>  

那該網頁會顯示：

1. location.href ： http://functionlab.org:80/tools/tcpproxy.php?user=FUNction#showscript  
2. location.protocol ： http  
3. location.hostname ： functionlab.org  
4. location.host ： functionlab.org:80  
5. location.port ： 80  
6. location.pathname ： /tools/tcpproxy.php  
7. location.search ： ?user=FUNction  
8. location.hash ： #showscript
