jQuery UI Accordion activate

I'm not getting how to do this, or if I can do this. I have a jQuery UI Accordion, multiple sections with each section containing multi开发者_运维百科ple anchor tags each with a unique string id.

I'd like to be able to have the accordion open to where a particular element with a given id is. Like say id "item117". Can I use something like

$('#accordion').activate('activate','#item117');

or even

$('#accordion').activate('activate',117);

I've tried those and some variations but can't get it to go. In the case I was trying to get working, the accordion should've opened to the end of the second section.

I'm still not getting this, so maybe I'm doing something else wrong as well. I've stripped it down to an example page here: http://www.ofthejungle.com/testaccordion.php Please have a look at it and its source.

have been over this too & found nice and universal solution
- emulate clicking the header of required item by its id

$('#header-of-item-258').click(); 

that works everytime and anywhere not just accordion

From documentation:

// getter
var active = $( ".selector" ).accordion( "option", "active" );

// setter
$( ".selector" ).accordion( "option", "active", 2 );

for me worked

$("#accordion").accordion({active:"h3:last"})

You need to call it using the function called accordion:

// Open the third set (zero based index)
$('#accordion').accordion('activate', 2); 

To open a section containing a specific element, you would do something like this. Note: you need to target the trigger that normally opens and closes the section. In the docs this is an h3 element, your trigger element may be different, so change this accordingly.

$('#accordion').accordion('activate', '#accordion > div:has(#item117) > h3'); 

This FINALLY worked for me:

$("#accordion").accordion("activate", $("#h3-id"));

NOTE!!! The id has to be that of the <h3> element you want to open up (in the default accordion setup).

I had the same problem with activating an accordion with #id. Sadly I hadn't found a way to this, so I've created a hack. I iterate through div elements in my accordion in order to get the index of interesting div. It looks like this:

acc = 'tab-you-are-interested-in';

// find corresponding accordion
act = 0;
panels = $('#accordion-element > div');
for (i=0; i<panels.length; i++) {
    if ( panels[i].id == acc ) {
        act = i;  
    }
}

$('#accordion-element').accordion('activate', act);

When you click on header, it is h3 element and it opens the next div..that is functionality. Now, For activate , you need to provide index or the element. index might be different than your id. so i would use :

$('.selector').accordion('option', 'activate', $(h3#id));

If you have index, you can use that..But most of the cases , if you created accordion dynamically, it is not easy to get index of an id. You can find indices like this..

 var processingHeaders = $('#accordion h3');
 for (i = 0; i < processingHeaders.length; i++) {

        ids.push($(processingHeaders[i]).attr('id'));
        idsForLaterChecks.push($(processingHeaders[i]).attr('id')); 
    }

now i got ids.. using indexOf : find the index in the array and use it..

Note: // idsForLaterChecks is global

With jQuery 1.9+ the:

$('#accordion').activate('activate', elementSelector);

is now:

$('#accordion').activate('option', 'active', elementSelector);

If you find it easier to use traversing methods, if you have HTML like this:

<div id="accordion">
    <h3><a href="#">Section</a></h3>
    <div>
        <p id="#item117" class="item">
            <a class="link-active" href="">Item 117</a>
        </p>            
    </div>
</div>

try this:

var myh3 = $('#item117').parent().prev('h3');
$('#accordion').accordion('option', 'active', myh3);

You can also enable and disable the accordion like this:

// Add the class ui-state-disabled to the headers that you want disabled
$( ".whatyouwantdisabled" ).addClass("ui-state-disabled");

To reactivate the tab:

// Remove the class ui-state-disabled to the headers that you want to enable
$( ".whatyouwantenabled" ).removeClass("ui-state-disabled");

Here's another way.

Include an ID="someId" in just each of the H3 header tags of the accordion and name the id's unique.

For example this id would be in series 'AccjA' the next h4 would be 'AccjB':

<h4 class="Accj" id="AccjA">
       <a href="#settings">A Fan?</a>
</h4>

Then activate whichever panel you wish with:

    $('#Accjoin').accordion('activate', '#AccjoinA')

I've used the above on a timeout to catch the attention of the user after the page is loaded with a 2 second delay using Ben Alman's ".doTimeout" function like:

$.doTimeout(2000, function () {
    $('#Accjoin').accordion('activate', '#AccjoinA')
});

Try

$('#accordion').activate('#item117');

or

$('#accordion').activate(document.getElementById('item117'));

The correct syntax for activating an accordion is

$(".selector").activate(var index)

where index is String,Element,boolean,Number,JQuery

Whatch the jquery API

Activate the second content of the Accordion contained in .

$(".selector").activate(1)

Close all content parts of the accordion.

$(".selector").activate(false)

Activate the first element matching the given expression.

$(".selector").activate("a:first")

$('#collapseOne').collapse('toggle');
