JavaScript Coding Tasks: You Are Here Location Script By Mike Prestwood

Posted 16 years ago on 12/3/2008 Take Away: A Javascript "You are here:" location script that uses your folder path to indicate location. KB101663

We used this script on prestwood.com for several years but stopped using it in December 2008 in favor of a simpler look.

The Script

Here's the script:

<!--

// location.js by Mike Prestwood.
//

// Global variables.

//

var sPath = location.href;

var pages = sPath.split("/");

var sTemp;

//

// Remove extension.

//

function GetPageName(PageName) {

 var sName = PageName;

 var sTemp;

  // String .html

  if (PageName.substr(PageName.length-5, 5) == '.html')

   sName = PageName.substr(0, PageName.length-5);

  // String .htm

  if (PageName.substr(PageName.length-4, 4) == '.htm')

   sName = PageName.substr(0, PageName.length-4);

  // String .shtml

  if (PageName.substr(PageName.length-6, 6) == '.shtml')

   sName = PageName.substr(0, PageName.length-6);

  // String .asp

  if (PageName.substr(PageName.length-4, 4) == '.asp')

   sName = PageName.substr(0, PageName.length-4);

  // String .aspx

  if (PageName.substr(PageName.length-5, 5) == '.aspx')

   sName = PageName.substr(0, PageName.length-5);

  // String .pl

  if (PageName.substr(PageName.length-3, 3) == '.pl')

   sName = PageName.substr(0, PageName.length-3);

  // String .cgi

  if (PageName.substr(PageName.length-4, 4) == '.cgi')

   sName = PageName.substr(0, PageName.length-4);

 // Uppercase first character.

 sTemp = sName.substr(0, 1);

 sTemp = sTemp.toUpperCase();

 sName = sTemp + sName.substr(1,sName.length);

 if (sName == 'Estore')

  sName = 'eStore';

 return sName;

}

//

// Write You are here: plus pages based on href.

//

document.write('You are here: <a href="/">Home</a>');

for (var Counter1=3; Counter1 < pages.length;) {

 sTemp = GetPageName(pages[Counter1]);

 if (sTemp == 'ASPSuite' && Counter1 <= 3)

   sTemp = 'PPC';

 if (pages[Counter1+1] == '' || pages[Counter1+1] == 'default.asp' || pages[Counter1+1] == 'home.asp') {

     document.write(' > ' + sTemp);

   } else {

     if (Counter1 == pages.length-1){

        // Write last section.

        if (sTemp != '' && sTemp != 'Index' && sTemp != 'Home' && sTemp != 'Default')

            document.write(' > ' + sTemp);

      }

     else {

      document.write(' > <a href="');

      for (var Counter2=3; Counter2 <= Counter1;){

       document.write('/' + pages[Counter2]);

       Counter2++;

      }

       document.write('">' + sTemp + '</a>');

     }

   }

 Counter1++

}

Save this script as location.js and put it in the root of your website.

Usage

Here's the include HTML:

<script language="JavaScript" src="/location.js"></script>

In the beginning, we had this at the top of every page. The top started to look cluttered so we moved it to the bottom of the page. In December 2008 we stopped using it entirely primarily because prestwood.com is so complicated already and the "feel" of the website is better without it.

Comment 1 of 2  This will be a progressive innovation! I can hardly wait to see the dispatch of AutoCAD programming and also they can check essaywritinglab services to manage their task. The designing understudies will be pleased with their vocation determination. Much obliged for sharing. Posted 47 months ago
