Using a comparison table. Mobile responsive problem when more than one table added?

The comparison table I am using is here:
https://codepen.io/adrianjacob/pen/KdVLXY
When I duplicate the tables and the viewer goes mobile responsive; the buttons are only working for the first table.
Is there any classes or such I can add to the JavaScript and HTML so I can make each group of buttons specific to their table?
Button code:
<ul>
<li class="bg-purple">
<button>Self-Employed</button>
</li>
<li class="bg-blue">
<button>Simple Start</button>
</li>
<li class="bg-blue active">
<button>Essentials</button>
</li>
<li class="bg-blue">
<button>Plus</button>
</li>
JavaScript code:
// DIRTY Responsive pricing table JS
$( "ul" ).on( "click", "li", function() {
var pos = $(this).index()+2;
$("tr").find('td:not(:eq(0))').hide();
$('td:nth-child('+pos+')').css('display','table-cell');
$("tr").find('th:not(:eq(0))').hide();
$('li').removeClass('active');
$(this).addClass('active');
});
// Initialize the media query
var mediaQuery = window.matchMedia('(min-width: 640px)');
// Add a listen event
mediaQuery.addListener(doSomething);
// Function to do something with the media query
function doSomething(mediaQuery) {
if (mediaQuery.matches) {
$('.sep').attr('colspan',5);
} else {
$('.sep').attr('colspan',2);
}
}
// On load
doSomething(mediaQuery);
I'd really appreciate any help, thanks for your time.

The problem is that your jQuery targets are currently too generic, so when you have multiples, it only finds content from the first one and puts it in both. What your script does is update both tables.
I've forked the Codepen, added a second table, and tweaked a couple of values on our comparison table, so you should see different things in each (and each set of tabs acts separately)
https://codepen.io/CapnHammered/pen/QzBbqN
Key part you're missing is some form of parent selector - in this case, we've used an article tag to wrap our table:
$( "ul" ).on("click", "li", function() {
var pos = $(this).index()+2;
$parent = $(this).closest('article');
$parent.find("tr").find('td:not(:eq(0))').hide();
$parent.find('td:nth-child('+pos+')').css('display','table-cell');
$parent.find("tr").find('th:not(:eq(0))').hide();
$parent.find('li').removeClass('active');
$(this).addClass('active');
});

Try this:
$("ul").on("click", "li", function(e) {
var $clicked = $(e.currentTarget); // This will give you the clicked <li>
var $ul = $clicked.parent();
var $table = $ul.next(); // Only works if the table immediately follows the <ul>
var pos = $clicked.index() + 2;
$table.find("tr").find("td:not(:eq(0))").hide();
$table.find("td:nth-child(" + pos + ")").css("display", "table-cell");
$table.find("tr").find("th:not(:eq(0))").hide();
$clicked.siblings().removeClass("active");
$clicked.addClass("active");
});
Basically, when you click a <li> you should search the next table and show/hide the information only on that table. Before you were selecting all <tr> elements so it would affect all tables in the page.
EDIT: after re-reading your question this sentence left me confused:
When I duplicate the tables and the viewer goes mobile responsive; the buttons are only working for the first table.
When I try to duplicate the tables in your codepen the buttons work for both tables, not sure if I'm understanding your problem.

Click outside an element doesn't work

I have this code:
function showAll(el){
var id = el.parentNode.id;
var all= document.getElementById(id).getElementsByClassName('items')[0];
if(all.style.display === 'block'){
all.style.display = 'none';
} else{
all.style.display = 'block';
window.addEventListener('mouseup', function(e){
document.getElementById('test').innerHTML = e.target.className;
if(e.target != all){
all.style.display = 'none';
}
});
}
}
<div id="parent">
<div class="selected" onClick="showAll(this);">
</div>
<div class="items" style="display: none">
</div>
</div>
Basically what i want to achieve is: click on selected to display items which is now hidden after that if i click again on selected or if i click outside of items(a random spot on that page or even on selected) i want to be able to hide items.
The problem is that without the EventListener when i click on selected it works to display items and then if i click again on selected it works to hide items but if i click on a random spot it doesn't work to close items.
But when i add EventListener and i click on selected it works to click a random spot to close items but it doesn't work to click selected again to close items.
Can anybody help me with a full JavaScript explanation, please?

You're going to want to use highly reusable code. I use change() and id_() on my web platform all of the time and it's very direct and simple. In the below example the second parameter will make the class empty (you can also use id_('items').removeAttribute('class') for a cleaner DOM (Document Object Model)).
HTML
<input onclick="change(id_('items','');" type="button" value="Display Items" />
<div clas="hidden" id="items"><p>Items here.</p></div>
CSS
.hidden {display: none;}
JavaScript
function change(id,c)
{
if (id_(id)) {id_(id).className = c; if (id_(id).className=='') {id_(id).removeAttribute('class');}}
else if (id) {id.className = c; if (id.className=='') {id.removeAttribute('class');}}
else {alert('Error: the class id \''+id+'\' was not found or has not yet been imported to the DOM.\n\nNew class intended: '+c);}
}
function id_(id)
{
if (id == '' && window['console']) {console.log('Developer: empty id called from: '+id_.caller.toString().split('function ')[1].split('(')[0]);}
return (document.getElementById(id)) ? document.getElementById(id) : false;
}
This code exists from years of refining the same platform instead of industry standard drama of pointlessly changing things. You are two clicks from finding more highly reusable functions on my platform's JavaScript documentation from the link in my profile.

Show/Hide Content without reloading the page

I have three content boxes that i want to show and hide using controls.
The HTML is as follows:
<div id="leermat1">
Content here
<a class="pag-next">Next</a>
<a class="pag-prev">Previous</a>
</div>
<div id="leermat2">
Content here
<a class="pag-next">Next</a>
<a class="pag-prev">Previous</a>
</div>
<div id="leermat3">
Content here
<a class="pag-next">Next</a>
<a class="pag-prev">Previous</a>
</div>
I have the two anchors pag-next and pag-prev that will control which of the content divs should be visible at any given point:
I want to write jquery such as, when #leermat1 'pag-next' is clicked, it hides #leermat1 and shows #leermat2. Then when #leermat1 is hidden and #leermat2 shows, when '.pag-next' is clicked, it hides #leermat2, and shows #leermat3.
Also the 'pag-prev' should work the same way.
I started with the following but dont know where to go from here.
$(document).ready(function() {
$('.pag-next').on('click',function() {
$('#leermat1').addClass('hide');
$('#leermat2').addClass('show');
});
});
One more thing is that the '.pag-next' should stop functioning after it has shown #leermat3.

You need this
$('[class^=pag-]').click(function() {
var elem = $('[id^=leermat]').filter(":visible"); // take the visible element
var num = Number(elem[0].id.match(/\d+$/)[0]); // take the number from it
var step = $(this).is('.pag-next') ? 1 : -1; // ternary operator
$('#leermat'+ (num + step)).show(); // show next or back
elem.hide(); // hide the visible element
});

Looks like in your anchor tag you have not given it a class.
Next
You then go on in your JQuery code to add a click function to a class which does not exist.
$('.pag-next').on('click',function()
Try adding class="pag-next" to your anchor tag.

This is what worked for me through a little trial and error. Although I am not sure if this is the most efficient solution.
$('#leermat1 .pag-next').on('click',function(){
$('#leermat1').addClass('hide');
$('#leermat1').removeClass('show');
$('#leermat3').addClass('hide');
$('#leermat3').remove('show');
$('#leermat2').addClass('show');
});
$('#leermat2 .pag-next').on('click',function(){
$('#leermat1').removeClass('show');
$('#leermat2').addClass('hide');
$('#leermat2').removeClass('show');
$('#leermat3').addClass('show');
});
$('#leermat2 .pag-prev').on('click',function(){
$('#leermat2').addClass('hide');
$('#leermat2').removeClass('show');
$('#leermat1').addClass('show');
$('#leermat3').removeClass('show');
});
$('#leermat3 .pag-prev').on('click',function(){
$('#leermat3').addClass('hide');
$('#leermat2').addClass('show');
$('#leermat1').addClass('hide');
$('#leermat3').removeClass('show');
$('#leermat1').removeClass('show');
});

how to repeat same Javascript code over multiple html elements

Note: Changed code so that images and texts are links.
Basically, I have 3 pictures all with the same class, different ID. I have a javascript code which I want to apply to all three pictures, except, the code needs to be SLIGHTLY different depending on the picture. Here is the html:
<div class=column1of4>
<img src="images/actual.jpg" id="first">
<div id="firsttext" class="spanlink"><p>lots of text</p></div>
</div>
<div class=column1of4>
<img src="images/fake.jpg" id="second">
<div id="moretext" class="spanlink"><p>more text</p></div>
</div>
<div class=column1of4>
<img src="images/real.jpg" id="eighth">
<div id="evenmoretext" class="spanlink"><p>even more text</p></div>
</div>
Here is the Javascript for the id="firsttext":
$('#firstextt').hide();
$('#first, #firsttext').hover(function(){
//in
$('#firsttext').show();
},function(){
//out
$('#firsttext').hide();
});
So when a user hovers over #first, #firsttext will appear. Then, I want it so that when a user hovers over #second, #moretext should appear, etc.
I've done programming in Python, I created a sudo code and basically it is this.
text = [#firsttext, #moretext, #evenmoretext]
picture = [#first, #second, #eighth]
for number in range.len(text) //over here, basically find out how many elements are in text
$('text[number]').hide();
$('text[number], picture[number]').hover(function(){
//in
$('text[number]').show();
},function(){
//out
$('text[number]').hide();
});
The syntax is probably way off, but that's just the sudo code. Can anyone help me make the actual Javascript code for it?

try this
$(".column1of4").hover(function(){
$(".spanlink").hide();
$(this).find(".spanlink").show();
});

Why not
$('.spanlink').hide();
$('.column1of4').hover(
function() {
// in
$(this).children('.spanlink').show();
},
function() {
// out
$(this).children('.spanlink').hide();
}
);
It doesn't even need the ids.

You can do it :
$('.column1of4').click(function(){
$(this); // the current object
$(this).children('img'); // img in the current object
});
or a loop :
$('.column1of4').each(function(){
...
});
Dont use Id as $('#id') for multiple events, use a .class or an [attribute] do this.

If you're using jQuery, this is quite easy to accomplish:
$('.column1of4 .spanlink').hide();
$('.column1of4 img').mouseenter(function(e){
e.stopPropagation();
$(this).parent().find('.spanlink').show();
});
$('.column1of4 img').mouseleave(function(e){
e.stopPropagation();
$(this).parent().find('.spanlink').hide();
});

Depending on your markup structure, you could use DOM traversing functions like .filter(), .find(), .next() to get to your selected node.
$(".column1of4").hover(function(){
$(".spanlink").hide();
$(this).find(".spanlink, img").show();
});

So, the way you would do this, given your html would look like:
$('.column1of4').on('mouseenter mouseleave', 'img, .spanlink', function(ev) {
$(ev.delegateTarget).find('.spanlink').toggle(ev.type === 'mouseenter');
}).find('.spanlink').hide();
But building on what you have:
var text = ['#firsttext', '#moretext', '#evenmoretext'];
var picture = ['#first', '#second', '#third'];
This is a traditional loop using a closure (it's better to define the function outside of the loop, but I'm going to leave it there for this):
// You could also do var length = text.length and replace the "3"
for ( var i = 0; i < 3; ++i ) {
// create a closure so that i isn't incremented when the event happens.
(function(i) {
$(text[i]).hide();
$([text[i], picture[i]].join(',')).hover(function() {
$(text[i]).show();
}, function() {
$(text[i]).hide();
});
})(i);
}
And the following is using $.each to iterate over the group.
$.each(text, function(i) {
$(text[i]).hide();
$([text[i], picture[i]].join(', ')).hover(function() {
$(text[i]).show();
}, function() {
$(text[i]).hide();
});
});
Here's a fiddle with all three versions. Just uncomment the one you want to test and give it a go.

I moved the image inside the div and used this code, a working example:
$('.column1of4').each(function(){
$('div', $(this)).each(function(){
$(this).hover(
function(){
//in
$('img', $(this)).show();
},
function(){
//out
$('img', $(this)).hide();
});
});
});
The general idea is 1) use a selector that isn't an ID so I can iterate over several elements without worrying if future elements will be added later 2) locate the div to hide/show based on location relational to $(this) (will only work if you repeat this structure in your markup) 3) move the image tag inside the div (if you don't, then the hover gets a little spazzy because the positioned is changed when the image is shown, therefore affecting whether the cursor is inside the div or not.
EDIT
Updated fiddle for additional requirements (see comments).

remove class from current group

The easiest way to see the problem is checking the code here: http://www.studioimbrue.com/beta
What I need to do is once a thumbnail is clicked, to removed the "selected" class from all other thumbnails that are in this same or without removing them from the other galleries on the page. Right now, I have everything working except the class removal. Someone helped me in another question but wasn't quite specific enough (my javascript skills aren't all that great!) I'm using jQuery. Thanks for the help.
Well in that case, I'm not sure why this doesn't work properly:
$(document).ready(function(){
var activeOpacity = 1.0,
inactiveOpacity = 0.6,
fadeTime = 100,
clickedClass = "selected",
thumbs = ".thumbscontainer ul li img";
$(thumbs).fadeTo(1, inactiveOpacity);
$(thumbs).hover(
function(){
$(this).fadeTo(fadeTime, activeOpacity);
},
function(){
// Only fade out if the user hasn't clicked the thumb
if(!$(this).hasClass(clickedClass)) {
$(this).fadeTo(fadeTime, inactiveOpacity);
}
});
$(thumbs).click(function() {
// Remove selected class from any elements other than this
var previous = $(thumbs+'.'+clickedClass).eq();
var clicked = $(this);
if(clicked !== previous) {
previous.removeClass(clickedClass);
}
clicked.addClass(clickedClass).fadeTo(fadeTime, activeOpacity);
});
});

I see you're using jQuery (and have edited your question accordingly).
With jQuery, it's really easy to get a list of matching elements using CSS syntax:
var list = $('#parentId > .selected');
That gets a list of the direct children of the element with the ID "parentId" that have the class "selected". You can then do things with them, such as:
list.removeClass("selected");
Then add "selected" to the element you want to select.
Edit I think this should do it:
$(thumbs).click(function() {
// Remove selected class from any elements other than this
var clicked, previous;
clicked = $(this);
if (!clicked.hasClass(clickedClass)) {
previous = $(thumbs+'.'+clickedClass);
previous.removeClass(clickedClass).fadeTo(fadeTime, inactiveOpacity);
clicked.addClass(clickedClass).fadeTo(fadeTime, activeOpacity);
}
});
I'm assuming there that the "selected" class isn't necessary for the fade effect to look right.
Note how the above will completely ignore the click if the clicked element already has the class. If you don't want that, remove the hasClass check and add .not(clicked) to the end of the previous = $(thumbs+'.'+clickedClass) line, but I don't know what your fade in would do at that point if you've already done it once.
I'm not getting the hover stuff; I thought you wanted this to happen on click, not hover.

You should take a look at
jQuery.removeClass()
So the point would be to first iterate trough all the images and unset the classname and than set the class on the active one.

Use .closest('.jcarousel-clip') to get the parent div,
then find all the thumbnails and use .removeClass('selected').

Hi Andy it isn't clear your question, but I am going to try to help you.
I am trying to help, and my skills on javascript arent that good either, plus I am not sure if I undertood the question right, please, dont vote me down.
function focusme(){
document.getElementById("focusme").focus();
}
function changeToCurrent(obj){
var menucont = document.getElementById('menu');
var arrLink = menucont.getElementsByTagName('a');
for (var i = 0 ; i < arrLink.length; i++){
arrLink[i].className='';
}
obj.className = "current";
}
<div class="menu" id="menu" >
<a href='' id='focusme' onclick='changeToCurrent(this)'>link1</a>
<a href='' onclick='changeToCurrent(this)'>Once Only link2</a>
<a href='' onclick='changeToCurrent(this)'>link3</a>
<a href='' onclick='changeToCurrent(this)'>link4</a>
<a href='' onclick='changeToCurrent(this)'>link5</
link6
</div>
Hope it helps.
