Jquery Next() not highlighting next element correctly when using a table

I have a table with each row representing a song.
When a song is clicked, the parent td should be highlighted a light blue color with the .active class and if any song was highlighted previously the parent td's .active class should be removed.
This part works fine and is represented with this jquery:
$(".songs").click(function(){
$('.songs').parents('td').removeClass('active');
$(this).parents('td').addClass('active');
});
I also want to have a next button and a previous button. This where I am having issues. When the next button is clicked, the next song on the list should be highlighted and the previously highlighted song should be unhighlighted (I am using the class .active to do the highlighting and unhighlighting). This part is not working:
$('#next_button').click(function(){
var current = $('td.active');
$('.songs').parents('td').removeClass('active');
current.nextAll('td:first').addClass('active');
});
Here is the jsfiddle link:

If you could help me solve this issue, I would greatly appreciate it. I feel like this should be so easy but I just can't seem to make it work.
Thanks!

The trick is to get the row index of the current song, add 1, and then do a modulo with number of rows that way if the current row+1 overflows the number of rows, it will start from the beginning:
$().ready(function() {
$(".songs").click(function(){
$('.songs').parents('td').removeClass('active');
$(this).parents('td').addClass('active');
});
$('#next_button').click(function(){
//here .parent() will get the current <tr>
//.parent().index() will get the index of the current <tr>
var currentID = $('td.active').parent().index();
//here .parent() will get the <tr>
//.parent().parent() will get the <tbody>
//.parent().parent().children() will get all the rows
//.parent().parent().children().length will get the row count
var nextID=(currentID+1)%($('td.active').parent().parent().children().length)
$('.songs').parents('td').removeClass('active');
$('td').eq(nextID).addClass('active');
});
});
.active{
background-color: #D9FAFA;
}
table{
text-align: center;
height: 100px;
width: 200px;

#table_head{

Something like this? http://jsfiddle.net/y5ntap04/3/
You needed to go up the DOM and then where all the siblings are, you can go to the next() one.
Plus added a previous button for you.
$().ready(function () {
$(".songs").click(function () {
$('.songs').parents('td').removeClass('active');
$(this).parents('td').addClass('active');
});
$('#next_button').click(function () {
$('.songs').parents('td.active').removeClass('active').closest('tr').next().find('td').addClass('active');
});
$('#previous_button').click(function () {
$('.songs').parents('td.active').removeClass('active').closest('tr').prev().find('td').addClass('active');
});
});

in your code you have each td in its own tr meaning there is no next td to go to.
you should adjust your jquery to focus on the rows, as in this fiddle (shown below)
$().ready(function() {
$(".songs").click(function(){
$('.songs').parents('tr').removeClass('active');
$(this).parents('tr').addClass('active');
});
$('#next_button').click(function(){
var current = $('tr.active');
$('.songs').parents('tr').removeClass('active');
current.next('tr').addClass('active');
});
});
You'll also notice I'm using .next() which will just grab the next element or the next element which matches the argument (in this case tr) - no need to get all then restrict to just the first.
All this will make your fiddle behave as expected, however, if you want to target the td's within each of the tr's you'll have to add .find('td') to get the td out of the retrieved tr, like this. Here the only line that is changed is the one that adds the class on click of next, which is now: current.parent().next('tr').find('td').addClass('active');
Refactoring out $('.songs').parents('tr').removeClass('active'); into it's own function would also clear your code a bit and make it easier to follow, a good habit! (also +1 for using a variable to store a returned JQuery DOM object - var current = $('tr.active'); - another good habit for code clarity and efficiency, especially when you are deraling with more complicated DOM structures and functions)

Javascript - Using Anchor to show/hide table from external link?

I'm new to Javascript and I'm working on a project. Thanks to help from a online help website, I'm able to show/hide my table successfully.
When I click the h3 element, it opens up and append the anchor (in this situation, #1, #2, #3) to the URL.
I want to use this anchor element to open up the specific table from an external link from another web page. (e.g. at Home Page, I clicked on this testing.html#1, I want it automatically open the 1st table when I reach the page)
Thank you very much!
JAVASCRIPT
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
function showonlyone(thechosenone) {
$('.newboxes').each(function(index) {
if ($(this).attr("id") == thechosenone) {
$(this).show(200);
}
else {
$(this).hide(600);
}
});
}
</script>
CSS
<style>
#special1{ display: none }
h3 {text-align: center;
background-color: black;
color: white;
clear: both;
cursor: pointer; }
.newboxes {
display: none;
}
a {text-decoration: none;}
</style>
HTML
<a id="myHeader1" onclick="javascript:showonlyone('newboxes1');" href="#1"><h3>Table 1</h3></a>
<table border="1" align="center" cellspacing="10px" class="newboxes" id="newboxes1">
<tr>
<td>1</td>
</tr>
</table>
<a id="myHeader2" onclick="javascript:showonlyone('newboxes2');" href="#2"><h3>Table 2</h3></a>
<table border="1" align="center" cellspacing="10px" class="newboxes" id="newboxes2">
<tr>
<td>2</td>
</tr>
</table>
<a id="myHeader3" onclick="javascript:showonlyone('newboxes3');" href="#3"><h3>Table 3</h3></a>
<table border="1" align="center" cellspacing="10px"class="newboxes" id="newboxes3">
<tr>
<td>3</td>
</tr>
</table>

Note this only work if you are loading from a html page in the same domain.
JQuery's .load function is very versatile. To load the first table from testing.html, we can do:
$('#tableContainer').load('testing.html table:eq(0)');
2nd table:
$('#tableContainer').load('testing.html table:eq(1)');
and so on.
demo
Note that the 3 tables in the demo are loaded from here
If the URL ends with #1, and you need showonlyone('newboxes1') automatically executed:
if (window.location.hash.substr(1) == '1') {
showonlyone('newboxes1');
}

Setting a td so that it links to javascript with onclick

Here is my html:
<div id="sidebar">
<table id="table1">
<tr>
<th>Table</th>
</tr>
<tr>
<td id="1">
<div>
<span>
Link 1
</span>
</div>
</td>
</tr>
</table>
</div>
<div id="box">
<img src="iow panorama.png" id="one"/>
<img src="iow panorama 2.png" id="two"/>
</div>
And my CSS:
#sidebar {
display: inline-block;
height: auto;
width: auto;
font-family: Garamond;
font-size: large;
}
#table1 {
border: 1px solid black;
text-align: center;
}
#table1 th {
border: 1px solid black;
}
#table1 td {
border: 1px solid black;
}
#box {
position: relative;
height: 200px;
width: 1200px;
}
#box #one,#two {
position: absolute;
top: 0px;
left: 0px;
}
#one {
visibility: hidden;
}
#two {
visibility: hidden;
}
#1 {
background-color:red;
cursor: pointer;
}
And Javascript:
$("#1").click(function(){
var z = parseInt($("#one").css("z-index"));
z =+ 10;
$("#one").css("z-index", z);
})
Now what I want to happen is the cursor to change to a pointer over the td, and when it is clicked, it triggers the javascript which makes the first image visible but not the second as they are overlayed. Also, the td isn't changing color, even though the CSS should be making it red. What I think is happening is the whole thing is failing at the table/td part of it. How can I fix it so that all of it works? (Also, how do I set the javascript to cause the z-index of the second image to decrease, so I can use another link in the table to create a kind of slideshow, with links to choose the image?)

You've got multiple issues going on here:
1 is not a valid HTML id value for many browsers. HTML 4 requirements for id values are:
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed
by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"),
colons (":"), and periods (".").
This is the cause of the red background style not applying to the td. HTML5 will eventually allow the value that you are using, but you will find many browsers not ready to support that fully.
You're images are both set to visibility: hidden;, but you never change that in your JS. Neither image will ever display, until you set it's visibility value to visible, regardless of what its z-index value is.
Depending on the operating system where your assets are hosted, you may run into issues with your the file names of your images having spaces in them. I would recommend not doing that . . . use and underscore instead of spaces, for example.
UPDATE
Actually, the issue with the id starting with a digit appears to be tied to CSS3 specifications for valid id selectors, rather than the HTML specification support. According to the CSS3 spec, the selector must be a "CSS Identifier", which . . . can contain only the characters [a-zA-Z0-9] and ISO 10646 characters U+00A0 and higher, plus the hyphen (-) and the underscore (_); they **cannot start with a digit**, two hyphens, or a hyphen followed by a digit. (emphasis added)

It would be better to provide id for the link than providing id for td
Also as you are going to make a link ( tag)it will automatically have cursor:pointer css.
It would be even better to use rel tags to relate the link and image
I couldnt properly understand your question. However I've made a JS FIDDLE. Hope this helps you. Since you've used $("#1").click() I assume you've used jQuery and I used the same in my code too.

here's a working example, id of elements shouldn't start with a number though.

Contextual menu on mouseover

I'm facing a little problem with my code :
<style>
.btn_remove{
position:absolute;
right:-25px;
}
.test:hover > table{
background-color:#708ab3;
}
</style>
<a href="page/ABC" class="test" ng-mouseenter="showRemove = true" ng-mouseleave="showRemove = false">
<div class="btn_remove" ng-show="showRemove"><img src="../../gfx/btn_remove.png" height="28" width="26" border="0"/></div>
<table cellpadding="0" cellspacing="0" border="0" width="100%">
<tr>
<td>mercedes class a</td>
<td>70'000</td>
</tr>
<tr>
<td><i>Nice car</i></td>
<td>Color: Red</td>
</tr>
</table>
</a>
So as you can see I have a table into a <a href>. When I pass my mouse over the table it calls the class .test:hover > table and also set the angular variable showRemove = true which will then show the absolute div on the right of the table.
My problem is when I mouse over the absolute div, it has the href from the parent (page/ABC).
If I try to write
<div class="btn_remove" ng-show="showRemove"><img src="../../gfx/btn_remove.png" height="28" width="26" border="0"/></div>
then nothing is working because the first link isn't closed.
How could i manage to get :
Mouseover on table = background change + link (page/ABC) + show remove image on the right.
Mouseover on remove image = JS function to be called or whatever but do not be part of the parent link.
Mouseout of table or remove image = remove "remove image" and remove background change.
All this without using jquery. JS or angular, but i guess it's mostly div and css.
Solution:
<style>
.test{
position:absolute;
right:-25px;
visibility:hidden;
}
.wrapper:hover table{
background-color:#708ab3;
}
.wrapper:hover .test
{
visibility:visible;
}
</style>
<div class="wrapper">
<div class="test"><img src="../../gfx/btn_remove.png" height="28" width="26" border="0"/></div>
<a href="table link">
<table cellpadding="0" cellspacing="0" border="0" width="100%">
<tr>
<td>Mercedes Class A</td>
<td>70'000</td>
</tr>
<tr>
<td><i>Nice car</i></td>
<td>Red</td>
</tr>
</table>
</a>
</div>

Glad to hear you got it working.
for reference you can add javascript:; to the href of an anchor to make it not do anything.
You can select a child element on hover using:
.parent:hover .child
{
the hover styles for the child
}
here is the fiddle for anyone else who needs to select a child element on hover jsfiddle.net/jE7J6

Click a button to show or hide a table

Please see the picture attached with this question. I have four tables with me. When I click certain table name (eg Table 1), I want that table to get displayed in the right hand side. When I click on some other table name, previous one should disappear and present one should be displayed.
I know only html. So, please tell me if this can be done alone with html. If not, I am allowed to use only CSS and JavaScript (I am new to both of these and will learn if they will be helpful, depending on your answer). If this can be achieved using only these 3 languages (viz HTML, CSS and JavaScript), please tell.

Here is the simplest way for you to start. It gives you an easy way to follow what's going on and how things works.
Also with this solution it's easy to add a server side code (asp/php) to deal with users who has javascript disabled.
Demo: http://jsfiddle.net/DEv8z/2/
Javascript
function show(nr) {
document.getElementById("table1").style.display="none";
document.getElementById("table2").style.display="none";
document.getElementById("table3").style.display="none";
document.getElementById("table4").style.display="none";
document.getElementById("table"+nr).style.display="block";
}
CSS
td {
vertical-align: top;
}
#table1, #table2, #table3, #table4 {
display: none;
}
HTML
Other things goes here ... <br /><br />
<table>
<tr>
<td>
<a href="#" onclick='show(1);'>Table 1</a>
<br />
<a href="#" onclick='show(2);'>Table 2</a>
<br />
<a href="#" onclick='show(3);'>Table 3</a>
<br />
<a href="#" onclick='show(4);'>Table 4</a>
</td>
<td>
</td>
<td>
<div id="table1"> Content of 1 </div>
<div id="table2"> Content of 2 </div>
<div id="table3"> Content of 3 </div>
<div id="table4"> Content of 4 </div>
</td>
</tr>
</table>
UPDATE
Using a file for each table would look like this:
table1.html
Other things goes here ... <br /><br />
<table>
<tr>
<td>
Table 2
<br />
Table 3
<br />
Table 4
<br />
.....
</td>
<td>
</td>
<td>
Content of 1
</td>
</tr>
</table>
-----------------------------------------------------
table2.html
Other things goes here ... <br /><br />
<table>
<tr>
<td>
Table 1
<br />
Table 3
<br />
Table 4
<br />
.....
</td>
<td>
</td>
<td>
Content of 2
</td>
</tr>
</table>
And if you can use server side includes and your "Other things...." will be the same for all tables, you can put that part in a separete file which gets injected with the each table content.

Try this FIDDLE
HTML :
<span id="sp1">Table 1</span>
<span id="sp2">Table 2</span>
<span id="sp3">Table 3</span>
<span id="sp4">Table 4</span>
<table border="1" id="t2">
<tr><td>22</td></tr>
<tr><td>22</td></tr>
</table>
<table border="1" id="t3">
<tr><td>33</td></tr>
<tr><td>33</td></tr>
</table>
JS :
document.getElementById('sp1').addEventListener("click",function(){
showTable('t1');
});
document.getElementById('sp2').addEventListener("click",function(){
showTable('t2');
});
function showTable(table){
var tables =['t1','t2','t3','t4'];
for(var i=0;i<4;i++){
document.getElementById(tables[i]).style.display = "none";
}
document.getElementById(table).style.display = "block";
}
P.S : Since I see no effort, the styling part i'm leaving it to you.

You will need JavaScript to do this. I have a JSFiddle with the code below. JSFiddle is interactive and lets you play with the solution. I'm relying on a popular JavaScript framework named jQuery to make this a bit easier. You will need to load the jQuery framework into your site to get this to work. Here is the JSFiddle link: http://jsfiddle.net/sU9Pf/
Here is the code that you can run interactively in the above JSFiddle link. First some example HTML:
<table id="one" border="1"><caption>Table One</caption></table>
<table id="two" border="1"><caption>Table Two</caption></table>
<table id="three" border="1"><caption>Table Three</caption></table>
<table id="four" border="1"><caption>Table Four</caption></table>
<div id="showTableHereWhenTableIsClicked">
<p>Click A Table To Show It Here</p>
</div>
Next is the JavaScript that makes it do what you want:
$(function() {
$('table').on('click', function() {
var tableClone = $.clone(this);
var stage = $('#showTableHereWhenTableIsClicked');
stage.prop('innerHTML', '');
$(tableClone).appendTo(stage);
});
});

The easiest way it can be done with just HTML would require you to build 4 different pages and just link between them. If you want it to 'seem' like it is all on one page, you can use HTML iframes to make it look like your many pages are one page by loading them into the current page.
It is possible to do this in one page with just HTML and CSS, but would require really tricky CSS and the :selected selector.
The easiest way to do it in 'one page' is to use Javascript. jQuery (a javascript library) would make it even easier.

You need to know javascript or jquery to do this.
Here is an example with jquery considering your tables have ids
table_1
table_2
table_3
table_4
And your right side container has an id right-container
So on click event you can do like
$("[id^=table_]").click(function(){
$("#right-container").html($(this).parent().html());
});

Please try it...
<style type="text/css">

This is easy to do, but will require the use of JavaScript.
It can not be done using html alone.
html without script is static.
When you add script to html you get dhtml (dynamic HTML) and you can make the rendered document change base on client interaction with the document.
Are you familiar with jsfiddle? It is a perfect tool to demonstrate this.
You will create 4 divs (or tables). You will give each an id and you will style each to be "display: none". You will create your table of contents as a list and using one of many methods, register a click event handler to the list.
The click event handler will set the display attribute of the visible div/table to none, then it will set the display attribute of the desired div/table to something other than none such as "block" or "table" and will finally store a reference to the visible div/table where it can be retrieved the next time the event handler is invoked.
