Click here for a solution in jsFiddle  What you need is you need to get window location pathname as mentioned and then create regexp from it and test it against navigation hrefs     function         var url   window location pathname           urlRegExp   new RegExp url replace                      create regexp to match current url pathname and remove trailing slash if present as it could collide with the link in navigation in case trailing slash wasn t present there            now grab every link from the navigation             menu a   each function                   and test its normalized href against the url pathname regexp             if urlRegExp test this href replace                                this  addClass  active

An easier way for me was   var activeurl   window location     a href    activeurl       parent  li   addClass  active      because my links go to absolute url  but if your links are relative then you can use    window location   pathname

I am guessing you are trying to mix Asp code and JS code and at some point it s breaking or not excusing the binding calls correctly   Perhaps you can try using a delegate instead  It will cut out the complexity of when to bind the click event   An example would be      body   delegate   menu li   click  function       var  li     this       var shouldAddClass    li find  a href   www xyz com link1     length    0      if shouldAddClass           li addClass  active               See if that helps  it uses the Attribute Starts With Selector from jQuery   Chi

window location href will give you the current url  as shown in the browser address   After parsing it and retrieving the relevant part you would compare it with each link href and assign the active class to the corresponding link

This works for me  basically the navigation is same   lt div id  main-menu  gt     lt ul gt       lt li gt  lt a href   lt  php echo base url     gt shop  gt SHOP lt  a gt       lt li gt  lt a href   lt  php echo base url     gt events  gt EVENTS lt  a gt       lt li gt  lt a href   lt  php echo base url     gt services  gt SERVICES lt  a gt     lt  ul gt   lt  div gt    Let s say you re at the URL   http   localhost project name shop detail shop   And you want the  SHOP  li link to get class  active  so you can visually indicate it s the active navigation  even if you re at the sub page of  shop  at  detail shop     The javascript    var path   window location pathname  var str   path split       var url   document location protocol          document location hostname         str 1          str 2        main-menu a href      url         parent  li   addClass  active       str will get  project name shop detail shop document location protocol will get http  document location hostname will get localhost str 1  will get project name str 2  will get shop   Essentially that will match links in the nav who s href attribute begins with  shop   or whatever the secondary directory happens to be

Use window location pathname and compare it with your links  You can do something like this      a href        currentSiteVar         addClass  active      But first you have to prepare currentSiteVar to put it into selecor

No other  addClass  methods worked for me when adding a class to an  a  element on menu except this one     function              var url   window location pathname      urlRegExp   new RegExp url replace                                 a   each function                                  if  urlRegExp test this href replace                                  this  addClass  active                                        This took me four hours to find it
