I've been trying to create a function that allow to move around a website without leaving the same page, just loading different contents on click.

I have this function on Javascript
function showPage(id) {
if (id=="page1") {
var pages = document.querySelectorAll("div");
for (var i = 0; i < pages.length; i++) {
pages[i].style.display = "none";
}
var le = document.getElementById('segunda');
le.style.display = "block";
}
The problem is that not all of the contents in the div#segunda are being loaded after the click triggers the function. All the elements of the div#abertura are removed, as it's supposed to do, but the only element that shows from the div#segunda is the img.fundo.
Any ideas? Please keep in mind that i'm a beginner in JavaScript.
The problem here is that you have divs inside segunda div. A better way to approach this would be to assign a class to the top-level divs, and then hide them using that class. For example here's an abridged version of the code.
<body>
<div id="1" class="container">...</div>
<div id="2" class="container">...</div>
</body>
Along with JS like
function showPage(id) {
if (id=="page1") {
var pages = document.document.getElementsByClassName("container");
for (var i = 0; i < pages.length; i++) {
pages[i].style.display = "none";
}
var le = document.getElementById('segunda');
le.style.display = "block";
}
Your html is missing some closing tags, so it is invalid. I have also fixed that.
Now, the changes:
It is a good idea to give your "pages" a common way to identify them so that you can query the DOM only for them. In this case, I have given them the class page. Your problem was that by doing var pages = document.querySelectorAll("div"); you were basically selecting all the divs on the page and then hide them, which has an undesired effect.
Next, it is also a good idea to uniquely identify the page containers somehow. This can be achieved by giving them an id. It is a good idea to have a format for these ids so you can easily work with them. In this case, I have given them the id page_x, where x is a number.
Going to the showPage function, we are now able to pass just the number of the page we want, e.g. showPage(1). Because we have a certain format for the ids, it is now more elegant to work with them. As you can see in the function, I used the .page class and then I compared the ids in the loop to determine what is to be shown and what to hide.
Another option would be to have display: none; on the .page class in css and have another class called active with display: block; and then just add this class to the div you wish to show and remove it from the others
Here's the updated html:

I am new to jQuery, and I loaded a div from an external HTML page and I wanted to perform functions such as click, hide, show, etc. The problem is that I tried to put the functions which I wanted to accomplish in the HTML pages script but they did not work. I see the div of #helpPage loaded.
The HTML page:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.2/jquery-ui.min.js"> </script>
<script>
$(document).ready(function(){
$( "#loadHelpHere" ).load( 'help.html #helpPage' );
$('#helpSection div').not(".helpDiv").hide();
$('.justClick').bind('click', function() {
$('#helpSection div').not(".helpDiv").hide();
$('#helpSection div.helpDiv').html($('#helpSection div.helpDiv' + ($(this).index()+1)).html());
});
});
</script>
<style>
#helpMenu ul li{margin: 0 0 5px 0;}
</style>
</head>
<body>
<div id="loadHelpHere"></div>
</body>
</html>
That is what was loaded into the div from the external HTML page:
<div id="helpPage">
<div id="helpMenu">
<header>Help Documentation</header>
<article>
<h4>Help Menu</h4>
<ul id="menu">
<li class="current_page_item justClick">Help Section 1</li>
<li class="justClick">Help Section 2</li>
<li class="justClick">Help Section 3</li>
</ul>
</article>
</div>
<div id="helpSection">
<div class="helpDiv">
<header>Help Documentation</header>
<article>
Works!
</article>
</div>
<div class="helpDiv1">
<header>Help Documentation content 1</header>
<article>
Help Section 1
</article>
</div>
<div class="helpDiv2">
<header>Help Documentation content 2</header>

</article>
</div>
<div class="helpDiv3">
<header>Help Documentation content 3</header>
<article>
Help Section 3
</article>
</div>
</div>
</div>
Any help is appreciated.
Event delegation is what you want to use for HTML elements that are dynamically loaded into the DOM. The .on() method is the place to start.
Example
$(document).on('click', '.justClick', function(e){
$('#helpSection div').not(".helpDiv").hide();
$('#helpSection div.helpDiv').html($('#helpSection div.helpDiv' + ($(this).index()+1)).html());
});
Any questions?
I need to convert this working filter gallery from JavaScript JQuery. I'm a complete novice in both these languages so I was hoping someone could give me a little help. Below is the JavaScript that will have to be converted,
(function() {
var filterButtons = document.querySelectorAll(".filterList a");
imageNodes = document.querySelectorAll("img");
console.log(filterButtons, imageNodes);
function staggerImage() {
TweenMax.staggerFromTo(imageNodes, 0.7, {opacity:0}, {opacity:1}, 0.3);
}
function doImageSwitch(event) {
console.log("fire");
console.log(event.target.parentNode.id);
for(i=0; i<imageNodes.length; i++) {
imageNodes[i].style.display = "inline";
if(!imageNodes[i].classList.contains(event.target.parentNode.id)) {
imageNodes[i].style.display = "none";
}
}
staggerImage();
}
[].forEach.call(filterButtons, function(el) {
el.addEventListener("click", doImageSwitch, false);
});
staggerImage();
})();
And this is the HTML code I have set up,
<?php
include './includes/functions.php';
$conn = connect($config);
$result = mysqli_query($conn, "SELECT * FROM main_content");
//echo mysqli_num_rows($result); ?>

Any help would be greatly appreciated. Thank you!
Did you write the javascript code yourself? If so it should not be a problem finding the answer. StackOverflow is as said not a coding service. I can try to help you, but I will not be wasting time on this question if it's for homework or some programming job ;)
If you first try to convert the code, I will be happy to help you (try).
the following uses an html structure that is presumably the same as your php echo output.
(function() {
// Selecting all of the img tags within the document that have to be changed
var imageNodes = $(".images img");
// TweenMax syntax stays the same
function staggerImage() {
TweenMax.staggerFromTo(imageNodes, 0.7, {opacity:0}, {opacity:1}, 0.3);
}
$(".filterList a").on("click", function(e) {
console.log("fire");
// parent() - http://api.jquery.com/parent/
//console.log('This: %o - Parent - %o - ParentId - %o', $(this), $(this).parent(), $(this).parent().attr("id"));
var parentId = $(this).parent().attr("id");
// [parentId] will be used as a scoped variable on the nested anonymous function declared in [.each] below.
// .each([array],func) | [array].each(func) - http://api.jquery.com/jquery.each/
$(imageNodes).each(function(index, value) {
console.log("index: %o | value: %o | parentId: %o", index, value, parentId);
// .hasClass([string]) - http://api.jquery.com/hasclass/
if($(value).hasClass(parentId))
{
$(value).css("display","inline");
} else {
$(value).css("display","none");
}
});
staggerImage();
});
staggerImage();
})();
img {width:5em; height:5em;border:0.1em solid black;}

Note: when you click on the hyperlinks, that we've attached click event handlers to, the viewport is being directed back to the top of the page.. this is usually undesirable, but it seems to be outside of the scope of this question to address that behavior.
Im trying to use the jQuery plug in videoBG to have a video fill a top div of 100% width and height. I'd like the #top-video to fill the #top-content. The issue is that nothing is showing up. Any suggestions? Thanks!

shouldn't you be using #top-video as your selector instead of #top_video ?
I'm applying a CSS class using .addClass when a tab is selected and it is also adding the class to the parents parent tab. The class is being added but the CSS doesn't seem to be taking effect of the parents parent class (apologies if that sounds awkward).
CSS:
.selectedTab{
color:#234 !important;
background-color:white !important;
}

How can I get the style to apply?
You need to add the selectedTab class to your anchor element, instead of the the li element:
$(this).parent().parent().children("a").addClass("selectedTab");

Canvas is a HTML5 element which IE8 doesn't supports.
Your doctype is also wrong since you're using HTML5 set it to: "".
As said in the comments: IE8 won't support the canvas tag. However there are some plugins that mimic it's behavior. I've used this one once: http://flashcanvas.net/ and it does the job, there's another called http://code.google.com/p/explorercanvas/. but i have no comment on that one, never used, don't know what to expect.
Just one note: the fallbacks will have their limitations, but as far as 2D drawing concerns, I think these will work out for you
