Best approach to slideup and tabs with jQuery - javascript

I'm creating a page with an image at the top, and a menu below. When the user clicks on on of the 3 menu buttons, the image slideUp and the page scrolls down so the menu is at the top of the page, then the right .content div fades in. The slideUp should only happen the first time the user clicks on of the buttons.
What the absolute best way to do this with jQuery? (no plugins)
I also need to know how I can't prevent it to fade in the page that is already visible if i click the same button twice?
I'm using rel instead of href, since the href made the page jump, even with return false.
This is what I have so far:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
imgVisible = true;
$('#mainmenu a').click(function(){
var $activeTab = $(this).attr('rel');
if(!imgVisible){
$('html:not(:animated),body:not(:animated)').animate({scrollTop:$('#mainmenu').offset().top-20},500);
$('.content').hide();
$($activeTab).fadeIn();
} else{
$('#imgholder').slideUp(500,function(){
imgVisible = false;
$('#mainmenu a[rel="'+$activeTab+'"]').click();
});
}
return false;
});
});
</script>
<div id="imgholder"><img src="image.jpg" /></div>
<div id="mainmenu">
<ul>
<li><a rel="#tab1"></a></li>
<li><a rel="#tab2"></a></li>
<li><a rel="#tab3"></a></li>
</ul>
</div>
<div id="container">
<div class="content" id="tab1">
content
</div>
<div class="content" id="tab2">
content
</div>
<div class="content" id="tab3">
content
</div>
</div>

The following code accomplishes what you need:
$('#mainmenu a').click(function(){
var myrel=$(this).attr('rel');
$('.content:not([id='+myrel+'])').hide();
$('#imgholder').slideUp(500,function(){
$('#'+myrel).fadeIn();
});
});
....
<li><a href='#' rel='tab0'></a></li>
I have removed the '#' sign from your rel='' piece ;-)
I am not sure why you would want to scroll the page. When a user clicks on the menu, he/she already has it focused (so it is visible inside the current viewport). But do you have a very large top image? If that is the case, let me know and I will modify the snippet. (Still, it depends on the amount of content below the menu visible when the page first loads.)
Also, for SEO reasons you might want to use the href instead of the rel attribute and create separate content holding pages. The following snippet would remove the navigation action.
$('#mainmenu a').each(function(){
var myhref = $(this).attr('href');
$(this).attr('href','#').attr('rel',myhref);
}).click(function(){
var myrel=$(this).attr('rel');
$('.content:not([id='+myrel+'])').hide();
//....etc

I think this is a great example of what your looking for: Organic Tabs

var imgVisible = true;
var $activeTab, $lastTab;
var $mainmenu = $('#mainmenu');
var offset = $mainmenu.offset().top - 20;
$mainmenu.find('a').click(function() {
$activeTab = $($(this).attr('rel'));
if (!imgVisible) {
// dont fire any events if already open
if ($lastTab.attr('id') == $activeTab.attr('id')) return false;
$lastTab.fadeOut('normal', function() {
$activeTab.fadeIn(500, function() {
$lastTab = $activeTab;
});
});
} else {
$('#imgholder').slideUp(500, function() {
imgVisible = false;
window.scrollTo(0, offset);
$activeTab.fadeIn(500, function() {
$lastTab = $activeTab;
});
});
}
return false;
});
I highly suggest adding <a href="#"> as this will not make the page jump when done properly and will ensure validation on your anchor links. Someone let me know if I missed something, it can be resolved quickly (or you can do it for me if you have an optimization or improvement).

Link to anchor and open accordion

How do I open an accordion panel by using an external anchor link?
I've tried using an anchor link and it just loads the page, without opening the panel.
What I'm trying to achieve is that when the anchor link is clicked, the page loads, scroll to the panel and then open the accordion.
This link is the one that will anchor to the other page and should open the accordion:
<a class="linkTo" href="/project#<?php the_sub_field('area_link'); ?>">
This is the code I am using to open the accordion on click:
$(document).ready(function() {
$(".accordion .accord-header").click(function() {
// for active header definition
$('.accord-header').removeClass('on');
$(this).addClass('on');
// accordion actions
if($(this).next("div").is(":visible")){
$(this).next("div").slideUp(600);
$(this).removeClass('on');
} else {
$(".accordion .accord-content").slideUp(600);
$(this).next("div").slideToggle(600);
}
});
});
This is the accordion structure:
<div class="accordion">
<div class="accord-header" id="<?php the_sub_field('area_link'); ?>">Accordion 1</div>
<div class="accord-content">
<!-- Content -->
</div>
</div>
</div>
You can use window.location.hash on document ready to initialize your accordion.
$(function () {
var $accordionSecion = $(window.location.hash);
if ($accordionSecion.length) {
$(window).scrollTop($accordionSecion.offset().top);
$accordionSecion.addClass('on');
}
});
You can probably use same handler with onhashschange listener to handle click on accordion titles.
Good luck. :)
$(document).ready(function(){
var hash = window.location.hash;
if (hash) {
var element = $(hash);
if (element.length) {
element.trigger('click');
}
}
});
try above code on the page where you want to open the accordion.

show pagination in a javascript tabs

I have this javascript code that allows me to show and hide tabs but my problem is when the user clicks on a link in the last tab it shows the first one. In another way the result of my clicks are hiden by the other tab.
Here is my javascript
$(document).ready(function() {
$("#content div").hide(); // Initially hide all content
$("#tabs li:first").attr("id","current"); // Activate first tab
$("#content div:first").fadeIn(); // Show first tab content
$('#tabs a').click(function(e) {
e.preventDefault();
if ($(this).closest("li").attr("id") == "current"){ //detection for current tab
return
}
else{
$("#content div").hide(); //Hide all content
$("#tabs li").attr("id",""); //Reset id's
$(this).parent().attr("id","current"); // Activate this
$('#' + $(this).attr('name')).fadeIn(); // Show content for current tab
}
});
});
This $('#' + $(this).attr('name')).fadeIn(); is where I think your problem is. That is some very messed up code. Without seeing your markup, I'm not even sure what you were trying to do, but that isn't it. Anyway, you ended up trying to do that because your solution is messy to begin with. See my example below. I only do what is necessary...no need to add ids and attributes to everything to hide/show the appropriate things.
Here is a light and simple way to accomplish what you're looking for. Live demo (click here).
sample markup:
<ul class="tabs">
<li>
<a>Tab1</a>
</li>
<li>
<a>Tab2</a>
</li>
<li>
<a>Tab3</a>
</li>
</ul>
<div class="content">
<div>Tab1 Content</div>
<div>Tab2 Content</div>
<div>Tab3 Content</div>
</div>
javascript:
$(document).ready(function() {
$(".content div").not(':first').hide();
var $content = $('.content');
$('.tabs a').click(function() {
var index = $(this).parent().index();
var $selected = $('div:eq('+index+')', $content);
$('div', $content).not($selected).hide();
$selected.show();
});
});

Jquery show/hide divs - fix overlapping animations

I am using JS to show/hide divs via clicking on the side nav with jquery functions fadeIn() and fadeOut(). The problem I run into is as one div fades out, the next is fading in simultaneously. Also, if I click the link for the div that is already shown, it fades out and fades in again. I'm not sure if an IF statement would be the best approach to do two fixes:
1. Let shown div fully fadeOut before next starts to fadeIn.
2. Currently shown div will not fadeOut/In if same link is clicked.
Here is what I have thus far (without my broken attempt at an IF statement):
http://jsfiddle.net/k55Cw/1/
HTML:
<div class="container">
<header>
<ul class="sidenav">
<li><h2><a data-region="nav-1" href="#">About</a></h2></li>
<li><h2><a data-region="nav-2" href="#">Services</a></h2></li>
<li><h2><a data-region="nav-3" href="#">Team</a></h2></li>
<li><h2><a data-region="nav-4" href="#">News</a></h2></li>
<li><h2><a data-region="nav-5" href="#">Contact</a></h2></li>
</ul>
</header>
<div id="nav-1" class="infozone"><p>Hello I'm box 1.</p></div>
<div id="nav-2" class="infozone"><p>Hello I'm box 2.</p></div>
<div id="nav-3" class="infozone"><p>Hello I'm box 3.</p></div>
<div id="nav-4" class="infozone"><p>Hello I'm box 4.</p></div>
<div id="nav-5" class="infozone"><p>Hello I'm box 5.</p></div>
</div>
CSS:
.infozone{
float:left;
height:400px;
width:800px;
background-color: #000;
display:none;
}
JS:
$(document).ready(function() {
$('.sidenav a').click(function(){
$('.infozone').fadeOut(850);
var region = $(this).attr('data-region');
$('#' + region).fadeIn(850);
});
});
to chain the animations put the fadeIn inside the callback for fadeOut, and to cancel the function if it's currently shown, check if the div is already visible.
I've also had to add a check to see if the current .infozone div is visible - or else the fadeOut applies to hidden elements too, and the callback fires multiple times:
$(document).ready(function() {
$('.sidenav a').click(function(){
var region = $(this).attr('data-region');
var $region = $('#' + region);
if ($region.is(':visible')) return;
var $infozone = $('.infozone:visible');
if ($infozone.length === 0) {
$region.fadeIn(850);
} else {
$infozone.fadeOut(850, function() {
$region.fadeIn(850);
});
}
});
});
You could something like that:
html
This make you page works when javascript is disabled:
<header>
<ul class="sidenav">
<li><h2>About</h2></li>
<li><h2>Services</h2></li>
<li><h2>Team</h2></li>
<li><h2>News</h2></li>
<li><h2>Contact</h2></li>
</ul>
</header>
note that the href point to the id you want to show. This will works also for screen reader if you want to make your page accessible.
javascript. I have not tested it, you might have to fix few things, but the idea is there
$(document).ready(function() {
$('.sidenav a').click(function(e){
var href = $(this).attr('href');
// prevent default
e.preventDefault();
// prevent clicked twice
if(!$(this).hasClass('active'){
$('.sidenav a').removeClass('active');
$(this).addClass('active'){
$('.infozone').fadeOut(850);
$(href.substring(1)).fadeIn(850);
}
});
You should also consider adding some ARIA attributes and roles attributes.

slide up jumps to top of page

I have some jQuery accordion sliders that slide down and slide up when clicked to reveal content.
Everything works as it should, but if you click on the same link to slide up the same content, it will jump to the top of the page.
I have
return false;
to prevent it jumping to the top of the page when another slider is clicked, so not too sure on what to use so that it doesn't jump to the top of the page to slide up the same content.
I've tied to add
event.preventDefault();
which works, but it breaks in IE9 and IE8.
Here's what I have:
$(document).ready(function() {
$('.slider').click(function() {
$('.internal').slideUp('normal');
if ($(this).next().is(':hidden') == true) {
$(this).addClass('on');
$(this).next().slideDown('normal');
return false;
}
});
$('.internal').hide();
});
HTML Sample:
<div class="slider">Slide Link 1</div>
<div class="internal">
Stuff1
</div>
<div class="slider">Slide Link 2</div>
<div class="internal">
Stuff2
</div>
You are going to want to prevent the default action of the click event. try this:
$(document).ready(function() {
$('.slider').click(function(e) {
e.preventDefault();
$('.internal').slideUp('normal');
if ($(this).next().is(':hidden') == true) {
$(this).addClass('on');
$(this).next().slideDown('normal');
return false;
}
});
$('.internal').hide();
});
the links probably have anchor tags like <a href="#" ...>, try to remove href="#" and if you still want that looks like a link with pointer cursor, use css:
a{
cursor: pointer;
}

Show/hide element based on clicked href of link

I am new to JavaScript and actually quite desperate by now
I have an HTML file that:
gets data from an XML file and displays them in various divs (e.g. )
these divs are hidden (by default) by a class name (class='box')
when a link is clicked, I pass the 'href' to the function showContent, remove the #, and then look for an element with that ID in the document.
then I add a new class name ('show') - so that this element shows up!
If you run the code you will see that every time you click on a link a new div is displayed...
So current problems:
replace already shown divs with the new clicked ID so that only one div shows up every time.
How can I avoid inserting the onClick event in every single tag - and make this more automated?
My code is as follows:
function showContent(obj)
{
var linkTo = obj.getAttribute("href");
var newlinkTo=linkTo.replace('#','');
//alert (newlinkTo);
document.getElementById(newlinkTo).innerHTML=" This is where the xml variable content should go";
document.getElementById(newlinkTo).className += " Show";
return true;
}
<a href="#b0" onClick="return showContent(this);">
<div id="text_content"> link2 </div>
</a>
<a href="#b1" onClick="return showContent(this);">
<div id="text_content"> link 1 </div>
</a>
<div class='box' id='b0'> abstract content </div>
<div class='box' id='b1'> introduction content </div>
I'm not usually into using jQuery everywhere, but with it you could just do:
<a class='showContent' data='b0'/>
Your js:
var selected;
$('a.showContent').on('click',function(e){
var toShow = $(this).attr('data');
if(selected!==undefined) selected.removeClass('Show');
selected = $(div+'#'+toShow);
selected.addClass('Show');
});
Not sure if this is what you want, but thought I'd suggest it.
This sort of thing is not hard to do without jQuery.
I would recommend using a hash-bang (#!) for Javascript activated links to keep it separate from other possible links with hashes. (script is at the bottom)
<div id="nav-links">
<a href="#!b0">
<div id="text_content"> link2 </div>
</a>
<a href="#!b1">
<div id="text_content"> link 1 </div>
</a>
</div>
<div class='box' id='b0'> abstract content </div>
<div class='box' id='b1'> introduction content </div>
<script type="text/javascript">
var links = document.getElementById('nav-links').getElementsByTagName('a');
for(var i = 0, link; link = links[i]; i++) {
link.onclick = showContent;
// Hide content divs by default
getContentDiv(link).style.display = 'none';
}
// Show the first content div
if(links.length > 0) showContent.apply(links[0]);
var current;
function showContent() {
// hide old content
if(current) current.style.display = 'none';
current = getContentDiv(this);
if(!current) return true;
//current.innerHTML = "This is where the xml variable content should go";
current.style.display = 'block';
return true;
}
function getContentDiv(link) {
var linkTo = link.getAttribute('href');
// Make sure the link is meant to go to a div
if(linkTo.substring(0, 2) != '#!') return;
linkTo = linkTo.substring(2);
return document.getElementById(linkTo);
}
</script>​
There is a WAY cleaner way to do this:
This is just my quick example, it can get EVEN cleaner than this, but this works for your case:
HTML:
link b0
link b1
<div class='box' id='b0'> abstract content </div>
<div class='box' id='b1'> introduction content </div>​​​​​​​​​
CSS:
#b0 { display: none; }
#b1 { display: none; }
a, div.text_content { display: inline; padding: 0 10px; }
JQUERY:
​$('.link').click(function(){
var id = $(this).attr("rel");
$('#'+id).slideToggle('slow');
});
​
Each link would have to have a REL attribute that is the same as the ID of the div element that you are trying to show.
Here is a JSFiddle to this example in action:
