Detect Current Page

Question

Is there a code snippet that can detect the current user's page and then add <a class="active"> to an item in a ul (my menu). I am making a tumblr theme and they do not allow PHP (I usually add <?php if ( $current == "home" ) { echo "class='active'" } ?> in my menu and $current = "home" on my pages) and they do not have a standard (such as current_page_item) so I need to do this with javascript (or jQuery) only. Is it possible?

Answer 1

It's not possible with HTML only but should be straight forward with JQuery, and just a bit harder with javascript only.

Here is a solution relying on JQuery and URL parser plugin: assuming you have the information you need in the file name (e.g: page1.html refered by id="page1")

$(document).ready(function() {
   var pathname = window.location.pathname;
   var page = jQuery.url.attr('file').replace(".html", "");
   $('#' + page).addClass("active");
});
