Copy original HTML code before DOM modification on button press

There is requirement where I need to copy HTML code on click of button. The functionality is not working where we are using a video tag. The video tag somehow gets formatted by brightcove. I tried using <pre> and <code> elements. Can you please suggest something.
$('.copy').on('click', function() {
var section = $(this).next().find('code').html();
var elem = document.createElement('textarea');
//elem.textContent = section;
elem.innerHTML = section;
//elem.classList.add('invisible');
document.body.appendChild(elem);
console.log(elem.innerHTML);
elem.select();
console.log("Hi");
try {
document.execCommand('copy');
} catch (e) {
console.log('ERROR: ' + e);
} finally {
elem.remove();
}
});

How to send emojis using jquery?

In my webpage, I have an input method and a button which opens a popup with smiles. When a user taps a smile once, the input value is changed to 'current value' + ':smile1:', for example. However, I have about 28 smile icons and this way to send emojis is a little bit difficult. How can I make this process easier? Because after this, I'll need to parse all 28 smiles and check if the input value equals one of them.
My popup:
<div class="smile-popuptext" id="smPopup">
<div class="smile1"></div>
<div class="smile2"></div>
<div class="smile3"></div>
//.....and other 25 divs
</div>
My function that sends the smile:
$('.smile1').on('click', function () {
var message = $('#message').val() + ' :smile1:';
$('#message').val(message);
});

I'd recommend giving all the buttons a single class and giving them unique id's.
So something like this:
<div class="smile-popuptext" id="smPopup">
<div class="smile" id="smile1"></div>
<div class="smile" id="smile2"></div>
<div class="smile" id="smile3"></div>
//.....and other 25 divs
</div>
Then:
$('.smile').on('click', function () {
var message = $('#message').val() + ' :' + this.id + ':';
$('#message').val(message);
});
JSFiddle

You could bind an EventListener on the container and defining the value as a data attribute:
var container = document.querySelector('.smile-popuptext');
container.addEventListener('click', function(event) {
var target = event.target;
var emoji = target.getAttribute('data-emoji');
if(emoji) {
console.log('clicked', [':', emoji, ':'].join(''));
}
});
<div class="smile-popuptext" id="smPopup">
<div class="sm1" data-emoji="smile1">1</div>
<div class="sm2" data-emoji="smile2">2</div>
<div class="sm3" data-emoji="smile3">3</div>
</div>

With no changes in your markup:
$('#smPopup div[class^="smile"]').on('click', function () {
var message = $('#message').val() + ' :' + this.className + ':';
$('#message').val(message);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="smile-popuptext" id="smPopup">
<div class="smile1">smile 1</div>
<div class="smile2">smile 2</div>
<div class="smile3">smile 3</div>
</div>
<textarea id="message"></textarea>

I found that there are 2 main issues there.
you use html() function which get the HTML contents of the first element in the set of matched elements. take a look document
-> you will get html instead of src of img. But later when you try to set src attribute during creating an 'edit area' so that is the mainly reason why image doesn't
display (.attr() function is better to get src attribute)
same wrong logic with message ( .text() function could be the better
solution in this case)
don't forget to check if you have create an edit area or not. At the moment every time it will create a new "edit area". Duplicate !
Hope it will help you a bit.

How to put a button active by default?

thanks in advance.
The question is:
I have 2 buttons that shows the content of the div when the user click on it.
The content of the div are in a function that shows the content when the users click on the button (onclick).
But when the page loads just appear the two buttons without any content, is there any way to 'put' one of these buttons as active by default?
I tried with this:
Html:
<div class="diferencias col-md-12 col-lg-12">
<div class="diferencias col-md-6 col-lg-6"><input type="button" value="Web" onClick="fashioncatweb();">
</div>
<div class="diferencias col-md-6 col-lg-6"> <input type="button" value="Logo" onClick="fashioncatlogo();">
</div>
</div>
<div class="row">
<div id="container">
<div id="content"></div>
</div>
</div>
JS:
function fashioncatweb()
{
var text = "<p>text";
var img = "images/.....";
var content = "<div class=\"col-md-7\"><div class=img><img class=img-responsive src=\"" + img + "\" alt=\"\" /></div></div>"
+ "<div class=\"col-md-5\"><div class=pre-scrollable id=\"fashion\">" + text + "</div></div>";
appendToContainer(content);
}
function fashioncatlogo()
{
var text = "<p>text";
var img = "images/....png";
var content = "<div class=\"col-md-7\"><div class=img><img class=img-responsive src=\"" + img + "\" alt=\"logo\" /></div></div>"
+ "<div class=\"col-md-5\"><div class=pre-scrollable id=\"logo\">" + text + "</div></div>";
appendToContainer(content);
}
$(document).ready(function () {
piramidalweb();
});
But it just works for one section and I have like 15 different sections.
Thanks again!!

You should have a function that is called on the click of the buttons:
Using pure Javascript:
<input type="button" value="Button1" id="btn1" onclick="showContent(this.id)" />
function showContent(id) {
if(id === "btn1") {
// show the content
}
}
Then call immediately at the base of the page within script tags:
showContent("btn1");
That will load the content immediately.
To improve this you would execute this function onload, or in a ready function within jQuery, but hopefully you'll be able to take it from there.

wrapInner() with href of children elements

I have next structure - there are 7 blocks:
<div class="blog-item">
<h2>...</h2>
<p>...</p>
<div class="jcomments-links">
<a class="readmore-link" href="..."></a>
</div>
</div>
I want to receive href of the inner link, delete its parent block with link and add a link inside block with class="blog-item" with the same href as deleted link...
I had wrote this:
<script>
jQuery(document).ready(function() {
jQuery(".blog-item a.readmore-link").each(function() {
var ahref = jQuery(this).attr("href");
jQuery(this).parent('.jcomments-links').remove();
jQuery(this).parent().closest('.blog-item').wrapInner(function () {
return "<a href='" + ahref + "'></a>"
});
});
});
</script>
But something wrong. There will not appear new link. Any help will be greatly appreciated. Thanks

Try this (run the snippet to see it work, and you'll have to use the inspector to see that the html is correct):
jQuery(document).ready(function ($) {
$(".blog-item a.readmore-link").each(function () {
var ahref = $(this).attr("href"),
$wrapItem = $(this).closest('.blog-item');
$(this).closest('.jcomments-links').remove();
$wrapItem.wrapInner('<a href="' + ahref + '"/>');
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="blog-item">
<h2>Heading</h2>
<p>Paragraph</p>
<div class="jcomments-links">
remove
<a class="readmore-link" href="http://www.example.com">example</a>
</div>
</div>

its because you are deleting $(this) when you remove the .parent('.jcomments-links') from the DOM, so the reference to add the <a> to the .blog-item has not reference when you say $(this).closest() cause there is no more $(this).
try this:
$(document).ready(function() {
$(".blog-item a.readmore-link").each(function () {
var ahref = $(this).attr("href");
$(this).closest('.blog-item').append("<a href='" + ahref + "'>This is my new link</a");
$(this).parent('.jcomments-links').remove();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="blog-item">
<h2>...</h2>
<p>...</p>
<div class="jcomments-links">
<a class="readmore-link" href="this-is-my-href-i-want">This is the Link woo woo</a>
</div>
</div>
