how can I collapse a specific part of an accordion styled on page load

问题

I have got links from several pages linking to a specific page where my accordion grid is. And on page load I want the target part of the accordion grid to collapse automatically for the user.

Take for example: Page A and Page B. Page A is where the user is coming from to view something on Page B. Page B has an accordion with 4 (e.g 1,2,3 & 4) parts. If the user click on link 2 from Page A to Page B, the number 2 part of the accordion should collapse for the user to see.

Find below the codes:

HTML:

<div id="accord_bar">
<ul id="accordion">
<li><a href="#recent" class="heading">Number 1 Header</a>
<ul id="recent"><li>Number 1</li></ul>
</li>
<li><a href="#popular" class="heading">Number 2 Header</a>
<ul id="recent"><li>Number 2</li></ul>
</li>
<li><a href="#categories" class="heading">Number 3 Header</a>
<ul id="recent"><li>Number 3</li></ul>
</li>
<li><a href="#archive" class="heading">Number 4 Header</a>
<ul id="recent"><li>Number 4</li></ul>
</li></ul></div>

Javascipt in the HEAD tag:

<script type="text/javascript">
$(document).ready(function() {
    $('#accordion').accordion(
    {active: "a.default", header: "a.heading"}
    );
});

Linked accordion Jquery file:

<script type="text/javascript" src="js/jquery-ui-accordion.js"></script>

I really need to fix this asap and I will be very grateful if anyone can help...

You can built your own simple accorion with jQuery, no need ui.

For collapsing a specific part of an accordion with eq() method with this simple accordion structure.

Here is jsFiddle with hover trigger.

jQuery:

$('.content').slideUp(100);
$('.content').eq(1).slideDown(600);
//for collapsing second part of an accordion

$('.panel').hover(function() {//open
    var takeID = $(this).attr('id');//takes id from clicked ele
    $('.content').stop(false,true).slideUp(600);
    //used stop for prevent conflict
    $('#'+takeID+'C').stop(false,true).slideDown(600);
    ///show's hovered ele's id macthed div
});

html:

<div class="panel" id="panel1">panel1</div>
<div class="content" id="panel1C">content1</div>

<div class="panel" id="panel2">panel2</div>
<div class="content" id="panel2C">content2</div>

<div class="panel" id="panel3">panel3</div>
<div class="content" id="panel3C">content3</div>

----------

Here is jsFiddle with click trigger and close button.

jQuery:

$('.content').slideUp(100);
$('.content').eq(1).slideDown(600);
//for collapsing second part of an accordion

$('.panel').click(function() {//open
   var takeID = $(this).attr('id');//takes id from clicked ele
   $('#'+takeID+'C').slideDown(600);//show's clicked ele's id macthed div
});
$('span').click(function() {//close
   var takeID = $(this).attr('id').replace('Close','');//strip close from id
   $('#'+takeID+'C').slideUp(600);//hide clicked close button's panel
});

html:

<div class="panel" id="panel1">panel1</div>
<div class="content" id="panel1C">content1<span id="panel1Close">X</span></div>

<div class="panel" id="panel2">panel2</div>
<div class="content" id="panel2C">content2<span id="panel2Close">X</span></div>

<div class="panel" id="panel3">panel3</div>
<div class="content" id="panel3C">content3<span id="panel3Close">X</span></div>
