After adding elements to a div with javascript, an untouched existing link stops working?

I have some html like this
<div id='myArea'></div>
<div id='aDifferentUnrelatedArea'></div>
<a href='#' id='closeButton' class='myButton'>Close</a>
the button has a listener like this
$('#closeButton').click(function(event){
event.preventDefault();
var myNode = document.getElementById("myArea");
while (myNode.firstChild) {
myNode.removeChild(myNode.firstChild);
}
});
and I add elements to myArea like this
document.getElementById('myArea').innerHTML = 'a title';
var newElement = document.createElement('a');
newElement.setAttribute('href', "#");
newElement.appendChild(document.createTextNode('a string'));
document.getElementById('myArea').appendChild(newElement);
Before I add elements, the Close button looks fine. There's nothing to close, but my hover css is applied to it and my cursor becomes the clickable one. After I add elements to myArea like this, the button acts more like a picture and there is no click related to it (it doesn't act like an <a> tag anymore nor does it do the click event).

Sorry for the confusion but thanks for helping me find the problem. The actual problem was I had this floating footer button at the bottom of the page. It seemed to take up the whole line's functionalities (I mean anything on the same line as the button would behave like a picture). I just added extra space at the bottom of the body so nothing would be on the same line as the footer.

jQuery: inserting text into container div on hover

I'm using a simple jQuery image slider (Owl Carousel) to show a list of speakers at a convention with photos, and I'm trying to find a way to overlay text associated with each speaker onto a div placed above the slider. I have a mockup page here. As you can see on the mockup, I have two primary divs-- i.e. div#sit and div#carousel-sit; within the former I have an container with the class .sit-quote-container into which I'd like the quote text/markup injected. I would like this overlay text to pull from the paragraph elements with the .sit-quote class that exist for each speaker.
In addition to the problem of displaying the appropriate text within the container div, I'm seeing that placing the .sit-quote paragraph within each slide is causing a gap to appear under the speaker name (the grey box underneath) and I have no idea why this is happening given that I've set .sit-quote to display:none. I'm wondering if perhaps I need to move the elements containing the quotations out of the slider markup altogether (?)
As for the actual hover function, this is what I have so far, with the help of another SO user; but it doesn't seem to be working:
$(".slide-sit").hover(function() {
var clone = $(this).find(".sit-quote").clone();
clone.appendTo(".sit-quote-container");
}, function(){
$(".sit-quote-container").html(""); // this clears the content on mouseout
});
Ultimately, I'd like the quotes to fade in/out positioned within the main div. Thanks for any assistance, and please let me know if I need to provide further clarification as to the aim here.

you should first visible that quote
try this:
$(".slide-sit").hover(function() {
var clone = $(this).find(".sit-quote").clone();
clone.appendTo(".sit-quote-container").show(); // Here you should show the quote
}, function(){
$(".sit-quote-container").html("");
});
if you want to fade in:
$(".slide-sit").hover(function() {
var clone = $(this).find(".sit-quote").clone();
clone.appendTo(".sit-quote-container").fadeIn(); //Here if you want to fade the quote
}, function(){
$(".sit-quote-container").html("");
});

Use the below script to pull the text from .sit-quote p tag of the hovered item and display it in the .sit-quote-container
UPDATE
If needed wrap the quote in a para tag and to avoid complexity use a different class name, in this case .sit-quote_inner.
CSS : .sit-quote_inner{ display:none; }
JS
$('.sit-carousel-container .owl-item').hover(function(){
var quote = $(this).find('.sit-quote').text(); //Only text not the p tag
quote = '<p class="sit-quote_inner">' + quote + '</p>';
$('.sit-header .sit-quote-container').html(quote);
$('.sit-quote_inner').fadeIn(); //Add this
},function(){
$('.sit-header .sit-quote-container').html('');
});

The carousel seems to be dynamically injecting clones of the slides. In this case, you might want to delegate your event handler so that it works with the dynamically generated slides.
Also, if you want to fadeOut the text, you should remove it in the complete callback of fafeOut instead of simply emptying the html Try
$(document).on("mouseenter",".slide-sit",function() {
var clone = $(this).find(".sit-quote").clone();
clone.appendTo(".sit-quote-container").fadeIn("slow");
});
$(document).on("mouseleave",".slide-sit", function(){
$(".sit-quote-container")
.find(".sit-quote")
.fadeOut("slow",function(){ // Fadeout and then remove the text
$(this).remove();
})
});
The gap (grey background) is the background of .slide-sit, which is visible due to the margin-bottom: 15px; applied on the paragraph containing name (style rule .item p main.css line 67 it seems), removing this will fix the issue.
Update
It'd be better if you keep a .slide-sit inside the .sit-quote-container so that you can fade it in/out properly using the below script.
$(document).on("mouseenter",".sit-carousel-container .slide-sit",function() {
var content = $(this).find(".sit-quote").html();
(".sit-quote-container .sit-quote").html(content).fadeIn("slow");
});
$(document).on("mouseleave",".sit-carousel-container .slide-sit", function(){
$(".sit-quote-container").find(".sit-quote").fadeOut("slow")
});

Image hide and show not working

I am using this jquery.smoothZoom.min.js to zoom and pan image.I have successfully applied that to my project for single image,now i want to add (<,>.i.e. corousal) ,so that I can use it for multiple images.When I add the corresponding part in my custom.js it does not work properly.
I will attach two screen sorts which will clear the picture
This is the first case
and after clicking the right corousal button
I can see only the background but not the required image . I can not understand what i am missing ,
This the html part i have been using
<div class="image-display" id="displayplan4" style="width:70%;height:120%; left:39%;top:10%;position:absolute;display:none;">
<img src="images/amenities.jpg" style="width:150%;height:130%; left:-60%;top:-20%;position:absolute;overflow:auto; z-index:1;">
<div style="width:150%;height:130%; left:-60%;top:-20%;position:absolute;background:rgba(255,255,255,0.7);z-index:2;">
</div>
<img class="planzoom" src="gallery/Residential/ongoing/Almog/Plan/almog1.jpg" id = "almogplan0" style="width:100%;height:100%; right:3%;top:50%;position:absolute;z-index:3;">
<!--button for forward and backward movement-->
</div>
and
<div id = "almogplandivII">
<img class="planzoom" src="gallery/Residential/ongoing/Almog/Plan/almog2.jpg" id= "almogplan1" style="width:100%;height:100%; right:3%;top:50%;position:absolute;z-index:3;display:none;">
</div>
and the corresponding js part to show and hide image on mouse click upon the image.
var almog_plan_div=0;
//Function for image forward with forward button
$("#almogforward").click(function ()
{
if(almog_plan_div<1)
{
$("#almogplan"+almog_plan_div).hide();
almog_plan_div++;
$("#almogplan"+almog_plan_div).show();
}
else
{
$("#almogplan"+almog_plan_div).hide();
almog_plan_div=0;
$("#almogplan"+almog_plan_div).show();
}
});
//Function for image backward with backward button
$("#almogback").click(function ()
{
if(almog_plan_div>0)
{
$("#almogplan"+almog_plan_div).hide();
almog_plan_div--;
$("#almogplan"+almog_plan_div).show();
}
else
{
$("#almogplan"+almog_plan_div).hide();
almog_plan_div=1;
$("#almogplan"+almog_plan_div).show();
}
});
I have tried like adding display:none style properties but it does not help my cause,
any help on this ?

Remove inline styling display: none from the img tag and then when u initialize your page, then hide that image using hide() function.
Inline-styling might be overriding this

Thanks to both of your answers ,both of u may not be exactly correct but definitely helped me getting me my solution.
The trick i was missing:
I) have used two different divs ,but i have not positioned the second one, (I noticed only that when I tried the whole thing in a new web page with only 2 images in it ,they were not positioned properly )my requirement needs the divs to be hidden ,i had to hide them.
2) The other thing i had to remove was the position:absolute thing from individual image elements.
Once rectified its cool now.

jquery remove() not removing

I have the following code that allows me to implement the shareThis functionality. What I am trying to do is when a the close button of the share this overlay is clicked I trying to remove the shareThis functionality that comes with the .share-span and then re-initialise it, however remove() does not seem to remove .span-share from the DOM.
<script type="text/javascript">
function getShareData() {
jQuery(".suit-gallery-btn").each(function(index){
jQuery(this).children().remove('span');
jQuery(this).append("<span class='share-span'></span>"); // ShareThis button will be inserted in this span, which we are appending to each <div class="suit-gallery-btn">
var suitLink = jQuery(this).find('a'); // the "click more information" link. you will need the href and title from this element.
console.log(suitLink);
stWidget.addEntry({
"service":"email",
"element": jQuery(this).find('.share-span')[0],
"title":suitLink.attr('title'),
"type":"large",
"text":suitLink.attr('title'),
"image": suitLink.attr('href'),
"summary":suitLink.attr('title'),
"onhover": false
});
});
}
jQuery(document).ready(function() {
getShareData();
jQuery("#closeX, #greyScreen, .stCloseNew2, .close, .close2").live("click", function(){
getShareData();
});
});
<div id="suit-gallery">
<img src="../images/galleries/business/DSC_0055_sm.jpg" alt="Stylish button 3 business suit, beige lightweight high twist cool wool Holland & Sherry" width="164" height="247" />
<div class="suit-gallery-btn">
Click for more information
</div>
</div>

change this line:
jQuery(this).children().remove('span');
to:
jQuery(this).children('span.share-span').remove();
See this in action here: http://jsfiddle.net/MarkSchultheiss/CUrXF/ where I slightly changed it to show the original span, then the removing when the function is called.

You've misunderstood the semantics of remove.
You call remove on the object that needs to be removed, not off the parent object you want to remove it from.
Something like:
jQuery('span.share-span', jQuery(this)).remove();

From what I can see, there is no span in the original code.
It looks like you are trying to remove() the span before you have appended it?

Link changing class of parent <div>, content of two <iframe> elements

Interesting (and rather complex) issue here...
What I have is a page with two iframes and a set of links at the top, each contained inside a div with an image background. What I want is for the contents of both iframes to change (to two separate html documents) when the link is clicked, and for the background image of the link's parent div to also change. I also, however, want the parent div to automatically change back to the original class when a different link is clicked (i.e. I have two classes, 'active' and 'waiting'. When a link is clicked (and its contents subsequently displayed in the iframes) I want it to switch to class 'active'. At all other times, though, (including after a different link might be clicked and become active) I want it to go back to using the 'waiting' class.)
Here's my current code / markup:
Javascript:
function changeFrame(link) {
$('#first iframe').src=link.href;
$('#second iframe').src= (Here would be the second link, not sure how to define that)
link.ParentNode.addclass("activebutton");
HTML:
<div class="waitingbutton">
<a href="yes.html" (Somewhere here would be the second link for the second iframe) class="waitingbutton" onclick="changeFrame(this);
return false;">Button Text</a>
</div>
(After this come four more divs, each identical bar Button Text and links)
As I suspect you can tell, I'm really just guessing here. Still not hugely familiar with Javascript, hoping someone can help me out.

You seem to be using jQuery.
Here's an ugly way to do it; but it works:
Button Text
And your JavaScript:
function changeFrame(link) {
$('#first iframe').attr("src", $(link).attr('href'));
$('#second iframe').attr("src", $(link).attr('secondary-href'));
return false;
}
Note that it'd be more idiomatic jQuery to do this without any onClick handlers, but simply initialise it all in your <head>/<script> from the beginning:
<script type="text/javascript">
$(function() {
$("a.iframe-link").click(function(event) {
$("#first iframe").attr("src", $(link).attr("href"));
$("#second iframe").attr("src", $(link).attr("secondary-href"));
// Whatever used to be the activebutton, make it 'waitingbutton', and remove
// the 'activebutton' class.
$(".activebutton").
addClass("waitingbutton").
removeClass("activebutton");
// Remove .waitingbutton from this, add .activebutton.
$(this).removeClass("waitingbutton").addClass("activebutton");
// Don't allow the link's default action (to follow the href in the normal
// way).
event.preventDefault();
});
});
</script>
Then later:
<a class="iframe-link waitingbutton" href="yes.html" second-href="whatever.html">Hello!</a>
