RussianQuestion
I am currently implemented a jquery based accordion on a navigation section, but some parts of the navigation don't need to be part of the accordion (if there are no categories etc) i am just wondering if it is possible to disable parts of the accordion or not ?
i get the feeling this could be impossible but this site has surprised me before :)
Thanks very much.
Solution
You can put classes on the things you want to disable.
Then do :
jQuery(".toDisable").live("click", function (){return false;});
or something similar
OTHER TIPS
Previous trick does not work because of the binding order of events, but the following works:
// Add the class ui-state-disabled to the headers that you want disabled
$( ".whatyouwant" ).addClass("ui-state-disabled");
// Now the hack to implement the disabling functionality
var accordion = $( "#accordion" ).data("accordion");
accordion._std_clickHandler = accordion._clickHandler;
accordion._clickHandler = function( event, target ) {
var clicked = $( event.currentTarget || target );
if (! clicked.hasClass("ui-state-disabled")) {
this._std_clickHandler(event, target);
}
};
Whenever you want to activate a tab, do:
// Remove the class ui-state-disabled to the headers that you want to enable
$( ".whatyouwant" ).removeClass("ui-state-disabled");
That's it
A simplistic way maybe using the unbind method:
$(".ui-state-disabled").unbind("click");
Adding the ui-state-disabled in the elements you want disable.
Like for a home link? I wanted a home link styled "regularly" at the top of my accordion. I'm using Google's 1.8 UI version:
< script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js">< / script >
Un-minified:
< script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.js">< / script >
I hacked the accordion a bit in its _clickHandler method (line 5834-ish). I added the following code just after the "var clicked = ":
// this.headers.index == My First "Home" Accordion H3.
if(this.headers.index(event.currentTarget) == 0){window.location='/support';return;}
i added the option linkDisabled to the plugin. this way you can define a class for the links inside the accordion object, which are disabled. e.g.:
$(myAccordion).accordion({
linkDisabled: 'disabled' // note that the class is given without dot. e.g. not '.disabled', but 'disabled'
});
and here's the rewritten plugin:

// The plugin can be called on the ID of the accordion element or on the ID of its closest named container.
// If the plugin is called on a named container, we can initialize all the accordions residing in a given section with just one call.
// EXAMPLES:
/* ---
$(function() {
// If the closest named container = #container1 or the accordion element is <ul id="subnavigation">:
/// Standard nested lists:
$('#container1').accordion(); // we are calling the plugin on the closest named container
$('#subnavigation').accordion({container:false}); // we are calling the plugin on the accordion element
// this will expand the sub-list with "id=current", when the accordion is initialized:
$('#subnavigation').accordion({container:false, initShow : "#current"});
// this will expand/collapse the sub-list when the mouse hovers over the trigger element:
$('#container1').accordion({event : "hover", initShow : "#current"});
// If the closest named container = #container2
/// Nested Lists + Headings + DIVs:
$('#container2').accordion({el: '.h', head: 'h4, h5', next: 'div'});
$('#container2').accordion({el: '.h', head: 'h4, h5', next: 'div', initShow : 'div.outer:eq(0)'});
/// Nested DIVs + Headings:
$('#container2').accordion({obj: 'div', wrapper: 'div', el: '.h', head: 'h4, h5', next: 'div.outer'});
$('#container2').accordion({objID: '#acc2', obj: 'div', wrapper: 'div', el: '.h', head: 'h4, h5', next: 'div.outer', initShow : '.shownd', shift: 'all'});
});
/// We can globally replace the defaults, for example:
$.fn.accordion.defaults.initShow = "#current";
--- */

/* ---
$.fn.accordion.defaults.container=false;
$.fn.accordion.defaults.event="hover";
$.fn.accordion.defaults.focus=false; // Optional. If it is possible, use {focus: true}, since {focus: false} will break the keyboard accessibility
$.fn.accordion.defaults.initShow="#current";
$.fn.accordion.defaults.lastChild=false;

I had a similar problem. I needed a 5 part accordion, but the last two parts were not to be accessible until the first three (which prompted for different actions) were completed. Here's how I handled it (using 2 separate accordions):
HTML:
<div id="accordion_1">
<h3 id="title1"><a href="#">Content for Title 1</a></h3>
<div>Content for Section 1</div>
<h3 id="title2"><a href="#">Content for Title 2</a></h3>
<div>Content for Section 2</div>
<h3 id="title3"><a href="#">Content for Title 3</a></h3>
<div>Content for Section 3</div>
</div>
<div id="accordion_2" class="faded_out">
<h3><a href="#">Content for Title 4</a></h3>
<div>Content for Section 4</div>
<h3><a href="#">Content for Title 5</a></h3>
<div>Content for Section 5</div>
</div>
Javascript:
$(document).ready(function(){
$('#accordion_1').accordion({
active:false,
collapsible:true
});
$('#accordion_1').click(function(){
$(this).siblings().accordion('activate',false);
});
$('#accordion_2').accordion({
active:false,
disabled:true,
collapsible:true,
});
$('#accordion_2').click(function(){
$(this).siblings().accordion('activate',false);
});
function ReleaseAccordion2(){
if($('h3#title1').hasClass('complete') && $('h3#title2').hasClass('complete') && $('h3#title3').hasClass('complete')){
$('#accordion_2').accordion('enable');
$('#accordion_2').removeClass('faded_out');
}
}
ReleaseAccordion2();
}
This way, we set up the second accordion so that it starts out disabled. Moreover, it is given CSS class 'faded_out' which gives some opacity and sets the mouse cursor to default for anchors. Finally, when either accordion is clicked, it sets 'activate' to false on the other so as to close the other accordion and make it seem like they are part of the same one. This works very well for me as is.
P.S. My app is on rails, and in order to detect whether or not the second accordion should be enabled (via the ReleaseAccordion2 function), I look for a class ('complete') passed to the h3's in the first accordion (via embedded ruby).
You can use the 'beforeActivate' event for this.
Add a disable class to your h3 element
<h3 class="accordionDisable disabledItemOne" >Title</h3>
Set the below function to the 'beforeActivate' event. The header object can be accessed via the 'ui.newHeader' object. Test if the header has 'accordionDisable' class, if true then return false and it will stop the accordion section from activating.
$( "#your_accordion" ).accordion({
beforeActivate : function( event, ui ){
if( ui.newHeader.hasClass( 'accordionDisable' ) ){
return false;
}
}
});
To activate the accordian section remove the 'accordionDisable' class
$( '.disabledItemOne' ).removeClass( 'accordianDisable' );
Use classes for the section you want to include, and make a more specific CSS selector when initializing the accordion.
Marcgg's answer seems to be on the right track. What you could do is add class to the links you want enabled in the accordion, get the href from them and then navigate url by setting the window.location.
$("a.enlnk").live("click", function() {
var navigateToLink = $.trim(this.href);
if (navigateToLink) {
window.location.href = navigateToLink;
}
});
I had the same issue. I wanted to stick in a div that wasn't a part of the accordion. It was a div whereas the other elements in the accordion were . I added the header: '' option and this prevented the classes from being added to the div that I had.
I can't seem to get the solutions given to work with the version of jQuery UI I'm using ATM (Version 1.8)
I did find another solution;
$(".toDisable").each(function(){
$(this)
.addClass("ui-state-disabled")
.unbind("click");
});
$('.disabled').addClass('ui-state-disabled').on('click', function () {
return false;
});<h3 class="disabled">Payment Information </h3>Licensed under: CC-BY-SA with attribution
