link to section onepage design

I tried to make a link to a section on a one page. It works strangely sometimes, but mostly it gets stuck at the section where you clicked the item and then if you want to scroll manually it does not work at all.
As far as I have seen on the Internet, there is no more to do than creating an a tag with href="#someID" and then clicking it, it should take me to the corresponding id or am I missing something?

Thank you so mcuh for your help #ProEvilz
I tried it outside of my IDE and now it works...
Seems to be a problem inside of brackets.

Function is trying to find a <div> but can't as it is display: none?

I have created a Tabs function below.
//Tabs ///
$('.tabs').each(function() {
var $tabs = $(this);
$tabs.find('.section-body > div:not(:first-child)').hide().end().find('.section-head a:eq(0)').addClass('active').end().find('.section-head a').on('click', function() {
$tabs.find('.section-head a').removeClass('active').end().find('.section-body > div:eq(' + $(this).index() + ')').show().siblings().hide();
$(this).addClass('active');
});
});
Here is the HTML:
<div class="section tabs">
<div class="section-head">
<a>Section A</a>
<a>Section B</a>
</div>
<div class="section-body">
<div>
<p>Section A</p>
</div>
<div>
<p>Section B</p>
</div>
</div>
</div>
This working fine, however, I wanted to use a Grid System plugin inside it, the plugin is here: http://loai.directory/Loai%20Aptana/assets/js/grid-system.js
So in order to use the Grid system plugin, the HTML of the tabs will look as follows:
<div class="section tabs">
<div class="section-head">
<a>Section A</a>
<a>Section B</a>
</div>
<div class="section-body">
<div>
<div class="grid" data-columns><!--Grid-->
<div>Section</div>
<div>Section</div>
<div>Section</div>
</div>
</div>
<div>
<div class="grid" data-columns><!--Grid-->
<div>Section</div>
<div>Section</div>
<div>Section</div>
</div>
</div>
</div>
</div>
Once I do that, I start getting this error: Uncaught TypeError: Cannot read property '1' of null for a live preview, visit http://loai.directory/Loai%20Aptana/profile and inspect the elements / open the browser console to see it.
I spent hours trying to debug this and fix it. One of the things I have tried, is to remove the tabs JS function and then grid system worked!, so I knew it was something to do with both plugins aren't working nicely together.
After farther dubbing, I found that the Grid System is trying to find the <div class="grid" data-columns> so it can apply the effect to it, however, the tabs function has hidden the one that is inside the second tab div:
<div>
<div class="grid" data-columns><!--Grid-->
<div>Section</div>
<div>Section</div>
<div>Section</div>
</div>
</div>
But, I mean the div is still in the DOM and therefor it should be accessible? What is wrong? how can I fix it?

Using JQuery hashtags to fade in & fade out content of a certain div

*EDIT: Here's a link to a staging version of the site: http://staging-site.site44.com/ *
I am extremely new to jquery so I apologize if this question is extremely simple. What I'm trying to do on my website is first when the page is loaded have the content in my #topContent div fade in.
But along with this I'd also like my main navigation to use jquery hashtags to switch up the page content displayed in the #topContent div. I've read up a bit on how to do this in jquery and from what I've read I think I need create page sections within my main html doc that are hidden until a certain nav link is selected - then hide the content that is currently showing and show the content associated with the nav link that was just selected, how close am I?
Here's my attempt so far at doing this...
HTML
<nav id="headerNav">
<ul class="navList">
<li class="navItem">Products</li>
<li id="view-about" class="navItem">About</li>
<li class="navItem">Portfolio</li>
<li class="navItem">Contact</li>
</ul>
</nav>
</div>
</div>
<!-- topMain -->
<div id="topContentWrapper">
<div id="topContent">
<div id="#products">
<h2>Test worked! - products </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="#about">
<h2>Test worked! - about </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="#portfolio">
<h2>Test worked! - Portfolio </h2>
<p>this test just worked sooo hard!</p>
</div>
</div>
</div>
JS
// Fade In Effect
$(document).ready(function() {
$("#topContent").css("display", "none");
$("#topContent").fadeIn(2000);
$("a.transition").click(function(event){
event.preventDefault();
linkLocation = this.href;
$("#topContent").fadeOut(1000);
});
function redirectPage() {
window.location = linkLocation;
}
$("#view-about").click(function(event){
$("#products").fadeOut(1000);
$("#portfolio").fadeOut(1000);
$("#about").fadeIn(1000);
});
});

Ok, this code should work:
$(function(){
$last = null;
$(".navList li a").click(function(){
if ($last != null) $last.fadeOut(1000);
$last = $($(this).attr("href"));
$($(this).attr("href")).fadeIn(2000);
});
});
However, you will need to change your topContent to this:
<div id="topContent">
<div id="products" style="display: none;">
<h2>Test worked! - products </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="about" style="display: none;">
<h2>Test worked! - about </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="portfolio" style="display: none;">
<h2>Test worked! - Portfolio </h2>
<p>this test just worked sooo hard!</p>
</div>
</div>
Reasons:
Firstly, you need your ids to be like this: id="about" and not this: id="#about".
The id specified doesn't need a # in front of it. (Same as how class doesn't need a . when setting a tag with it)
The jQuery code I tested locally, so it should work.
Note:
You may want to automatically have some different content automatically displayed, because right now as it loads it is blank until you click one of the links.
Hope this helped!
Edit:
I suggest you change the code to this:
ids = [ "products", "about", "portfolio" ];
links = [ "Products", "About", "Portfolio" ];
$(function(){
$last = null;
$(".navList li a").click(function(){
New = "#" + ids[links.indexOf($(this).text())];
if ($last != null) $last.fadeOut(1000);
$last = $(New);
$(New).fadeIn(2000);
});
});
Because it will keep all the content constantly in the same place. For this to work, you'll need to change two more sections of your code:
<ul class="navList">
<li class="navItem">Products</li>
<li id="view-about" class="navItem">About</li>
<li class="navItem">Portfolio</li>
<li class="navItem">Contact</li>
</ul>
And:
<div id="topContent">
<div id="products" style="display: none; position: absolute">
<h2>Test worked! - products </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="about" style="display: none; position: absolute">
<h2>Test worked! - about </h2>
<p>this test just worked sooo hard!</p>
</div>
<div id="portfolio" style="display: none; position: absolute">
<h2>Test worked! - Portfolio </h2>
<p>this test just worked sooo hard!</p>
</div>
</div>
That last part was just my suggestion, but do whatever you need to.

Instead of doing this in your a.transition handler:
$("#topContent").fadeOut(1000);
do:
$("#topContent").children().fadeOut(1000);
The issue is that you're actually fading out the higher level item thus the children are no longer visible even if you fade them in.

HTML5 2 Audio tags

I have two audio tags in these markup. my problem is that the second one won't play
<div class="container">
<div class="post-container">
<legend>
<strong>Zedd - Spectrum</legend>
</h4>
<div class="art-item">
<img src="uploads/arts/default.jpg">
</div>
<audio class="audio-player" src="uploads/tracks/02 So Far.mp3"></audio>
<div class="playerContainer">
<ul id="playerControls">
<li class="play-bt"></li>
<li class="pause-bt"></li>
<li>
<div class="progressContainer">
<!-- Progess bars container //-->
<div class="progressbar"></div>
</div>
</li>
</ul>
<span class="timecode">0:00</span>
</div>
</div>
<div class="post-container">
<legend>
<strong>Zedd - Spectrum</legend>
</h4>
<div class="art-item">
<img src="uploads/arts/default.jpg">
</div>
<audio class="audio-player" src="uploads/tracks/track3.mp3"></audio>
<div class="playerContainer">
<ul id="playerControls">
<li class="play-bt"></li>
<li class="pause-bt"></li>
<li>
<div class="progressContainer">
<!-- Progess bars container //-->
<div class="progressbar"></div>
</div>
</li>
</ul>
<span class="timecode">0:00</span>
</div>
</div>
</div>
And here is the script that plays the track
$(".play-bt").click(function(){
var $artItem = $(this).parent(".art-item");
console.log($artItem);
$artItem.find('audio').play();
$artItem.find(".message").text("Music started");
});
My problem is that I can only play the first audio tag. what can I do to play the second tag or 3rd audio tag if there's more? the counter is the one that is selecting what audio tags to play. but as of now I have no idea how would I make the second audio tag or user selected audio tag if the are more audio post in this markup.

not 100% sure that's the only issue but you use id a lot. id's should be unique on a page. Replace them by classes
And your references are wrong.
$("#play-bt").click(function(){
// -> will allways try to play song indicated by counter (0)
$(".audio-player")[counter].play();
$("#message").text("Music started");
})
I don't think you want that? Don't you want to play the audio in the "post-container" ?
you could do something like this:
$(document).ready(function(){
$(".play-bt").click(function(){
var $post= $(this).parents(".post-container");
$post.find('audio')[0].play();
$post.find(".message").text("Music started");
});
});
​
=> and changing the play-bt and message id's into classes

The reason why things don't work for you is because of your markup... in your code you try to obtain "parent" of the clicked "play-bt" class, yet "art-item" is NOT parent in your DOM structure. What probably makes you think it is, is your incorrect markup indentation...

Javascript Accordion Not Working, DD not sliding down

I have a Javascript Accordiong, currently it displays the first dd when page is loaded, then when you click on a dt tag, the dd that is open should close and the dd tag within the dt clicked show slidedown.

Working demo http://jsfiddle.net/UL3V3/1/
Good read: API : http://api.jquery.com/visible-selector/
slideToggle http://api.jquery.com/?ns0=1&s=slideToggle&go=
Using this you can close the open dd as well.
Rest you can play around and find out the behavior.
This will help. B-)
Jquery code
$(document).ready(function() {
$('dd:not(:first)').hide(); //hides all but the first dd (the content under the headings)
$('dt').click(function() {
if ($(this).next('dd').is(":hidden"))
$('dd').slideUp('slow');//slides up current dd
$(this).next('dd').slideToggle('slow');
});
});​

$(this) in your case is the 'dt' so you need to find the next element ('dd'):
$('dt').click(function() {
if ($(this).next().is(":hidden")){
$('dd:visible').slideUp('slow'); //slides up current dd
$(this).next().slideDown('slow');
}
});
EDIT also added a condition to only animate the slide if the current dd is hidden.
