Question

i am trying to open the the accordion using external link..Actually there are three main accordions on the page(about,results,contact)

and there is a menubar with items(about,results,contact).

what i want is when i click on about menu item it should open the about accordion

the below is jquery code

$(function() {

    $( "#accordion" ).accordion({              
        collapsible: true,
        autoHeight: false , 
        active: false,
        navigation:true,       

    }); 

    $(".exlnk").click(function(event){
           window.location.hash=this.hash;
            });         
});

The below is html menubar code:

    <div id="navmenu" style='z-index:9999;'>
      <ul>
        <li><a href="#anchor_about" class="anchor_about">About</a></li>
        <li><a href="#" >Results</a></li>
       <li><a href="#" class ="anchor_contact">Contact</a></li>
      </ul>
    </div>

and below is jquery code for external link

    <script>

     $(document).ready(function(){

     $('a.anchor_about').click(function(){

     $("#accordion").accordion("activate", '<?php echo $_GET['id']; ?>');

 return false;

  });
   });

   </script>

Answer 1

$('a.anchor_about').click(function(){

   $("#accordion").accordion("activate", '<?php echo $_GET['id']; ?>');

   return false;

});

I don’t think $_GET[‘id’] in the accordion activate line is going to work as I guess you want something like this

$('a.anchor_about').click(function(){
   var sectionId = $(this).attr("href");
   $("#accordion").accordion("activate", sectionId);

   return false;

});

check if this works – if there are any errors let me know.

EDIT **

Also, I think to open accordion you need an index based value not a ID value like #someId (which works for tab for sure). The index is zero-based so that first section of accordion can be activated by passing a zero value, second with 1, and so on.
