javascript - Is link pointing to this page? -

for website's navigation want give links current page color.
how find links pointing current page?
link's href "../index.php" current page http://mysite.myserver.com/index.php.

this current approach, doesn't want work:

string.prototype.endswith = function(str) { return ( this.match(str + "$") == str ); } string.prototype.startswith = function(str) { return ( this.match("^" + str) == str ) } string.prototype.trim = function(sec) {     var res = this;      while (res.startwith(sec))     {         res = res.substr(sec.length);     }      while (res.endswith(sec))     {         res = res.substr(0, res.length - sec.length);     }      return res; } 

and, when document ready:

$("a").each(     function (i)     {         if (window.location.pathname.endswith($(this).attr("href").trim(".")))         {             $(this).addclass("thispage");         }     } ); 

and yes, know might color home link (../index.php - because pages end that!). that's why need better way...

$("a[href]").filter(function() {     return window.location.pathname === this.pathname; }).addclass("thispage"); 

regarding comment, if window.location directory, can create string ends index.php.

var win = window.location.pathname;  if( win.slice(-1) === '/' ) {      win += 'index.php';  }  $("a[href]").filter(function() {     return win === this.pathname; }).addclass("thispage");
