Nice way to dinamicaly identify current url ( or more closer ) into a menu using javascript

kbueno-js-url-detection.js

  $(document).ready(function() {
    var currentURL = metaphone(location.href);
    var minPercent = 11.00;
    var lastMatch = '';
    
    $('#mymenu > ul > li > a').each(function() {
          var url = $(this).attr('href');
          var compare = metaphone(url);
          var dist = levenshtein(currentURL,compare);
          var percent = ( (dist/Math.max(currentURL.length,compare.length)) * 100 );
          
          if(percent < minPercent) {
            minPercent = percent;
            lastMatch = $(this);
          }
          
//          alert(url + ' | ' + location.href + ' ['+percent+'] - ' + compare + ' | ' + currentURL);
    });
    
    
    
    $('#mymenu > ul > li').removeClass('current');
    lastMatch.parents('li').addClass('current');
  });
