append() fail to make boostrap component works

This drive me crazy, i've this simple html bootstrap-gentelella template that works almost in every page of the site that im developing, the html is so simple:
(this code make the part in the class "x_content" visible or not visible by clicking the "collapse-link" class in the "a" tag)
<div class="x_panel">
<ul class="nav navbar-right panel_toolbox">
<li>
<a class="collapse-link freccia_feed">Replies
<i class="fa fa-chevron-up"></i>
</a>
</li>
</ul>
<div class="x_content" style="display: none;">
<div class="input-group col-md-12 col-sm-12 col-xs-12">
<input data-role="tagsinput" id="risposta_'+j+'_D_'+element+'" class="form-control risposta_domanda_'+element+'" name="reply" value="" placeholder="Insert one solution" type="text">
<span class="input-group-btn">
<button id="elimina_risp_'+j+'_D_'+element+'" class="btn btn-danger glyphicon glyphicon-trash" > </button>
</span>
</div>
</div>
</div>
be carefull that the part like id="risposta_'+j+'_D_'+element+'" have no sense in this static part, and rendered as is it, just for example, I use that in the jQuery function that fail to make it works!
here:
$("#domanda_"+element).append(
'<div class="x_panel">'+
'<ul class="nav navbar-right panel_toolbox">'+
'<li>'+
'<a class="collapse-link freccia_feed" >Replies'+
'<i class="fa fa-chevron-up"></i>'+
'</a></li></ul>'+
'<div class="x_content" style="display: none;">'+
'<div class="input-group col-md-12 col-sm-12 col-xs-12">'+
'<input data-role="tagsinput" id="risposta_'+j+'_D_'+element+'" class="form-control risposta_domanda_'+element+'" name="reply"'+
'value="" placeholder="Insert one solution" type="text">'+
'<span class="input-group-btn"><button id="elimina_risp_'+j+'_D_'+element+'" class="btn btn-danger glyphicon glyphicon-trash" >'+
'</button></span>'+
'</div></div></div>');
I've tried many options to make this string works inside append() and the only one that seems working it to wrap the whole string with single ' using double " for ids class etc. and then inject javascript variable with single ' and +. Same thing for new line.
I even try to escape the whole string with online escape tools like https://www.freeformatter.com/javascript-escape.html
but still the same result, the component not works if is appended!

the problem is in the "inizialization" of the class ".collapse-link" by gentelella js.
So i move the function under my "div" generation function's.
I even add a "unbind()" func to resolve the problem that "inizialization" can toggle even the allready rendered div making them open anc closing several time...
thats the code if someone can find it usefull
cheers
$(".collapse-link").unbind("click");
$(".collapse-link").on("click", function() {
var a = $(this).closest(".x_panel")
, b = $(this).find("i")
, c = a.find(".x_content");
a.attr("style") ? c.slideToggle(200, function() {
a.removeAttr("style")
}) : (c.slideToggle(200),
a.css("height", "auto")),
b.toggleClass("fa-chevron-up fa-chevron-down")
});

Get the index of a specific class repeated on the DOM

In my HTML I have a div that is repeated, it is something like this:-
<div class="col-md-3 SeccaoProduto">
<p class="productName"></p>
<p>Quantidade Atual: <span class="quantidadeProduto"></span></p>
<button class="btn btn-default btn-xs IncrementaProduto"><span class="glyphicon glyphicon-arrow-up"></span></button>
<button class="btn btn-default btn-xs DecrementaProduto"><span class="glyphicon glyphicon-arrow-down"></span></button>
</div>
When I click the button that has the DecrementaProduto class, I want to get the specific index of that class, in this case DecrementaProduto is the first time that it appears on my html, I want the index = 0;
In my JavaScript I tried this:-
$(".DecrementaProduto").click(function(){
console.log($(".SeccaoProduto").index(this));
});
But I always get the value = -1 :S
How can I do this?

In your code $(this) refers to the clicked button but the collection does not include the button so the returned value would be -1.
Instead, you need to get the parent element .DecrementaProduto which contains the clicked element. Where you can use the parent() method to get the element.
$(".DecrementaProduto").click(function(){
console.log($(".SeccaoProduto").index($(this).parent()));
// ------------^^^^^^^---
});

How to change html inside a span

I want to change the content of a span in my form
HTML:
<form action="javascript:submit()" id="form" class="panel_frame">
<label>Origin:</label>
<div class="input-group" id="input-group">
<input type="text" id="origin" name="origin" class="form-control">
<span class="input-group-btn">
<button id="btn-default" class="btn btn-default" type="button">
<span class="glyphicon glyphicon-pushpin" aria-hidden="true"></span>
</button>
</span>
</div>
What I want change is che content of <span class="input-group-btn"> with
<button id="btn-default" class="btn btn-default" type="button">
<span class="glyphicon glyphicon-remove" aria-hidden="true"></span>
</button>
So what change is: the icon pushpin to remove and the action useCurrentPosition to clearPosition.
I' using jquery and despite I've read other answer about similar question on Stack like: How can I change the text inside my <span> with jQuery? and how to set a value for a span using JQuery I haven't solved the issue.
I tried:
$("#input-group span").html('
<button id="btn-default" class="btn btn-default" type="button" onclick="br_bus.useCurrentPosition()">
<span class="glyphicon glyphicon-pushpin" aria-hidden="true"></span>
</button>
');
,giving an id to the span and also modify the full div, but none solved my problem.
What am I missing?

Here's a way to overcome the problem of changing the onclick attribute, which is bad practice, without storing a Global var, and using jQuery delegation (learn to use it, it's really good):
$(document).on('click','.btn', positionChange); // Give that button an id on his own and replace '.btn' with '#newId'
// Not using an anonymous function makes it easire to Debug
function positionChange(){
var $btn = $(this), // Caching jQuery elements is good practice
$span = $btn.find('span'), // Just caching
pushpinApplied = $span.hasClass('glyphicon-pushpin'); // Check which icon is applied
( pushpinApplied ) ? useCurrentPosition() : clearPosition();
$span.toggleClass( 'glyphicon-pushpin glyphicon-remove' );
}

Rather than changing the function called in the onclick attribute I suggest having a flag in one function to define the logic it should follow.
For example:
function positionChange(this){
var $this = $(this);
if(!$this.data("currentpositionused")){
//useCurrentPosition() code here
$this.data("currentpositionused", true);
}
else {
//clearPosition() code here
$this.data("currentpositionused", false);
}
Then change your HTML to:
<button class="btn btn-default" type="button" onclick="positionChange(this)">

If you want to change only the onclick attribute of the button inside the particular span you can use the following in your script.,
$(document).ready(function(){
$("span.input-group-btn button").attr("onclick","clearPosition()");
});
EDIT
$(document).ready(function(){
$("span.input-group-btn button").attr("onclick","clearPosition()");
$("span.input-group-btn button span").attr("class","Your_class");
});
And also learn about how to change/add/remove attribute values....

Try this:
$("span.input-group-btn").html('<button class="btn btn-default" type="button" onclick="clearPosition()">
<span class="glyphicon glyphicon-pushpin" aria-hidden="true"></span>
</button>');

Is it like This ?
how to change onclick event with jquery?
$("#id").attr("onclick","new_function_name()");
jquery change class name
$("#td_id").attr('class', 'newClass');
If you want to add a class, use .addclass() instead, like this:
$("#td_id").addClass('newClass');

Swap 2 div elements Javascript

So I want to swap two div elements that have a CKEditor inside. I viewed some of the previous questions and tried to do it that way. It's all OK, the elements are swapped. But one of the elements loses its content and becomes non-editable.
<div id="sections">
<div id="apresentacao_div">
<label id="apresentacao_label" for="apresentacao">Apresentação</label>
<button class="btn btn-default">
<span class="glyphicon glyphicon-remove"></span>
</button>
<button class="btn btn-default">
<span class="glyphicon glyphicon-arrow-up"></span>
</button>
<CKEditor:CKEditorControl ID="apresentacao"></CKEditor:CKEditorControl>
</div>
<div id="intro_div">
<label id="intro_label" for="intro">Introdução</label>
<button class="btn btn-default" onclick="remove(this)">
<span class="glyphicon glyphicon-remove"></span>
</button>
<button class="btn btn-default" onclick="upDiv(this)">
<span class="glyphicon glyphicon-arrow-up"></span>
</button>
<CKEditor:CKEditorControl ID="intro"></CKEditor:CKEditorControl>
</div>
</div>
I want to swap the two divs within the div with the id = "sections". And this is my code to swap:
function upDiv(ex) {
var div = document.getElementById("sections").getElementsByTagName("div");
for (i = 0; i < div.length; i = i + 4) {
if (div[i + 4].id.localeCompare(ex.parentNode.id) == 0) {
swapElements(div[i + 4], div[i]);
return false;
}
}
return false;
}
function swapElements(obj1, obj2) {
obj2.nextSibling === obj1 ? obj1.parentNode.insertBefore(obj2, obj1.nextSibling) : obj1.parentNode.insertBefore(obj2, obj1);
}
The for loop increments by 4 because of the transformation of the textarea into CKEditor adds a lot of new divs (4 in this case).
Can anyone help?

Not having too much familiarity with exactly what you are doing but i would try using a 'clone' method and then removing the original element off the page. It may be the values are not being copied, only the outline is but a clone should mean it duplicates as it is on the page and not how it is from the page source.

What about just swapping the data instead? Moving the DOM elements around is causing problems to me as well, but this works:
Replace your upDiv with this:
function upDiv()
{
var introData = CKEDITOR.instances['intro'].getData();
var presentacaoData = CKEDITOR.instances['apresentacao'].getData();
CKEDITOR.instances['intro'].setData(presentacaoData);
CKEDITOR.instances['apresentacao'].setData(introData);
return false;
}
This takes the data from one, and puts it in the other and vice versa.
Also, I noticed your controls don't have the runat server attribute set. You may want to change this:
<CKEditor:CKEditorControl runat="server" ID="intro"></CKEditor:CKEditorControl>
Finally, you call the function from your button like this:
<button class="btn btn-default" onclick="return upDiv();">
<span class="glyphicon glyphicon-arrow-up"></span>
</button>

Javascript/JQuery to create a div -Simple Way

I have this code in a div:
<div class="user_event my_background">
<%= image_tag("events_pics/boom.png", :class=> 'event_pic_small') %>
<h6 class="event_info">Event_1: Frame: 974</h6>
<a class="btn btn-mini btn-danger pull-right " href="#"><i class="icon-remove"></i></a>
</div>
and I want this to be appended into an other element each time I click on a button. Anyway the main question is, Is there an easy way to create the above div using javascript? for example a function that takes that as an argument and creates it? Thanks

This simple Jquery function will set the html inside the element selected to whatever you want.
$("SomeElement").html("<div class='user_event my_background'>...</div>")
Just specify the element you want to add the html to and the rest of you html as the argument and you are good to go. Hope that helps.

If you can use jQuery then
$(".user_event").clone().appendTo("#MyTargetElement");
Edit:
Instead of creating a the div again and again, I'd recommend that you keep it hidden in some element and get it using that hidden element's id and append it to your target element.
<div id="myhiddenelement" style="display:none;">
<div class="user_event my_background">
<%= image_tag("events_pics/boom.png", :class=> 'event_pic_small') %>
<h6 class="event_info">Event_1: Frame: 974</h6>
<a class="btn btn-mini btn-danger pull-right " href="#"><i class="icon-remove"></i></a>
</div>
</div>
jQuery
("#MyTargetElement").append($("#myhiddenelement").html());

Use this script:
$("body").prepend('<div>').addClass("user_event").addClass("my_background");
function addElement()
{
$(".user_event.my_background").append('<h6 class="event_info">Event_1: Frame: 974</h6>');
$(".user_event.my_background").append('<a class="btn btn-mini btn-danger pull-right " href="#"><i class="icon-remove"></i></a>');
}
Hope this helps! :)

function append_to_what(id)//id can be any css3 selector
{var div=document.createElement('div');
div.innerHTML='<%= image_tag("events_pics/boom.png", :class=> "event_pic_small") %><h6 class="event_info">Event_1: Frame: 974</h6><a class="btn btn-mini btn-danger pull-right " href="#"><i class="icon-remove"></i></a>';
'
div.className='user_event my_background';
document.querySelector(id).appendChild(div);
}

You may want to check Jquery where you can access a div using class name.
