AppendChild a element above a cerain element

So i have a div element which will be filled dynamically with others divs using the appendChild Method, this should display a list. The User is now able to sort that list with the JqueryUI Sortable option.I also added some sortable option attribues like follows:
Options:
$("#NameContainer").sortable("option", "axis", "y");
$("#NameContainer").sortable( "option", "containment", "parent" );
LIST
<div id="NameContainer" class="ui-widget">
<div id="Name_1">John</div>
<div id="Name_2">Jack</div>
<div id="Name_3">Charlie</div>
<div id="Name_4">Sawyer</div>
<div id="Name_5">Yin</div>
<div id="Name_6">Ben</div>
</div>
Now comes my problem. The appendChild always inserts the new div at the bottom of the container but i want to to add some space at the bottom of to the Container Div with a "br" or something like that. I want to add that space to make sure that when the user sorts the last item of that list it will get sorted correctly because the "containment" bounds sometimes wont allow to sort under the last item.
<div id="NameContainer" class="ui-widget">
<div id="Name_1">John</div>
<div id="Name_2">Jack</div>
<div id="Name_3">Charlie</div>
<div id="Name_4">Sawyer</div>
<div id="Name_5">Yin</div>
<div id="Name_6">Ben</div>
<br><!--SPACEHOLDER-->
</div>
So here comes my Question is there away to appendChild above a certain element? Like a "br" "div" or "p"?

Try this instead of appendChild:
Please note I have used random value to add in div as I don't have your dynamic value.
check fiddle: https://jsfiddle.net/dqx9nbcy/
<div id="NameContainer" class="ui-widget">
<div id="divspacer"></div>
</div>
<button id="btn">ADD Element</button>
$(document).ready(function(){
$("#btn").click(function(){
var parentnode = document.getElementById("NameContainer");
var existnode = document.getElementById("divspacer");
var rand = Math.floor((Math.random() * 10) + 1);
var newName = document.createElement("div");
newName.setAttribute("id", rand);
newName.setAttribute("value", rand);
newName.setAttribute("class","ui-widget-content");
newName.innerHTML = rand;
parentnode.insertBefore(newName,existnode);
});
});

refer http://api.jquery.com/appendto/ but you need to make sure that your are targeting right tag.

You can try with this code snippet.
HTML Snippet
<div id="NameContainer" class="ui-widget">
<div id="Name1">Name1</div>
<div id="Name2">Name2</div>
<div id="Name3">Name3</div>
<div id="Name4">Name4</div>
<br>
<br>
</div>
Javascript Snippet
$(document).ready(function(){
$("#btn").click(function(){
var containerDiv= $("#NameContainer");
var childList = containerDiv.children("div");
var newElementid = childList.length;
var newName = document.createElement("div");
newName.setAttribute("id", "Name"+(newElementid+1));
newName.setAttribute("value", "Name"+(newElementid+1));
newName.setAttribute("class","ui-widget-content");
newName.innerHTML = "Name"+(newElementid+1);
$(childList[childList.length-1]).after(newName);
});
});
This is specific to a situation where there are some elements in the initial list. The same can be modified for dynamic list of implementation by validating that childList.length is != 0 before using the same.

copy text from one div to other div using javascript

<div id="noty">Hello</div>
<div id="noty">World</div>
<div id="noty">Nation</div>
<div id="textArea"></div>
$("#noty").click(function() {
$("#textArea").html($("#noty").html());
});
I'm using this to copy text from one div to other by onclick function. But this is not working. It's only working on the first div. Is there any way to accomplish this ?

Use something like this:
<div class="noty">Hello</div>
<div class="noty">World</div>
<div class="noty">Nation</div>
<div id="textArea"></div>
<script>
$(".noty").click(function() {
$("#textArea").html($(this).html());
});
</script>
https://jsbin.com/giqilicesa/edit?html,js,output

Like this.
$(".noty").click(function(e) {
$("#textArea").html(e.target.innerHTML);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="noty">Hello</div>
<div class="noty">World</div>
<div class="noty">Nation</div>
<div id="textArea"></div>

Yes. var s = ''; $('.noty').each(function () {s += $(this).html();}); $('#textarea').html(s); but change your divs to use class="noty" instead of id. The id should be unique.

At first, you must not use multiple id attribute. And another problem is sizzle providing jQuery as a selector engine returns result to use getElementById. It means even if you've declared multiple ids, you'll get just only one id element. When consider those problems, you can get over this problem to follow this way:
<div class="noty">Hello</div>
<div class="noty">World</div>
<div class="noty">Nation</div>
<div id="textArea"></div>
<script>
var $noty = $('.noty');
var $textarea = $('#textArea');
$noty.click(function () {
var text = Array.prototype.map.call($noty, function (el) {
return $(el).html();
}).join(' ');
$textarea.html(text);
});
</script>

How to add div dynamically inside a div by class - Jquery

I want dynamically add info div into every dynamic class.
HTML
<div id='container'>
<div class='dynamic'></div>
<div class='dynamic'></div>
<div class='dynamic'></div>
<div class='dynamic'></div>
</div>
I want like this.
<div id='container'>
<div class='dynamic'><div class="info">info</div></div>
<div class='dynamic'><div class="info">info</div></div>
<div class='dynamic'><div class="info">info</div></div>
<div class='dynamic'><div class="info">info</div></div>
</div>
JS FIDDLE

You can use $.wrapInner method
$(".dynamic").wrapInner('<div class="info">info</div>');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container">
<div class="dynamic"></div>
<div class="dynamic"></div>
<div class="dynamic"></div>
<div class="dynamic"></div>
</div>

To add an info div into every class using jQuery, simply use:
$( ".dynamic" ).append( "<div class='info'>info</div>" );
The JSFiddle demonstrates it.
If you want to continually check for .dynamic classes, you can use something like this:
$(document).ready(setInterval(function(){
$( ".dynamic" ).append( "<div class='info'>info</div>" );
}, 1000));
In the above case, you are checking for .dynamic classes every 1000ms (1 second).
Hope this helps.

Try using append():
$('.dynamic').append($('<div/>', { class: 'info' }).html('info'));
Update your fiddle:
http://jsfiddle.net/4cncLor7/2/
If your .dynamic div already contains content and you want to at the .info div at the beginning use prepend():
$('.dynamic').prepend($('<div/>', { class: 'info' }).html('info'));

I have updated it. Please check and give me feedback.
http://jsfiddle.net/4cncLor7/4/
jQuery('.dynamic').html('<div class="info">info</div>');

You could do something like this:
$('.dynamic').each(function() {
var newDiv = $('div');
newDiv.addClass('info');
newDiv.html('info');
//inject the new div
$(this).append(newDiv);
});

check this code : Example
Javascript:
var vof=$("#box1").val();
//$(".result-box").text(vof);
var e = $('<div class="result-box">'+vof+'</div>');
$('#box').append(e);
HTML :
<div id="box">
<!--<div class="result-box" id="rbx"></div>-->
</div>
here i am creating dynamic div so that every time button is clicked it create new div and you can add attribute id to them separately

hide all but one element of certain class in Jquery

I am trying to create an effect whereby clicking on a title toggles the corresponding content div. Clicking on another title while some content is showing should hide that content div and show the content div corresponding to the title just clicked.
However the code is not doing anything, as you can see on the following jquery: http://jsfiddle.net/dPsrL/
Any ideas?
HTML:
<div class="row title">
<div class="title" industry_id="education">Ed</div>
<div class="title" industry_id="tech">Tech</div>
<div class="title" industry_id="finance">Fin</div>
</div>
<br>
<br>
<div class="row content">
<div class="content" id="education">Education is great</div>
<div class="content" id="tech">Technology is awesome</div>
<div class="content" id="finance">Finance is super</div>
</div>
JAVASCRIPT:
$(document).ready(function () {
$('.content').hide();
});
('.title').on('click', function () {
var clicked = $(this).attr('industry_id');
alert(clicked);
$("#"+clicked).toggle(400);
$("#"+clicked).siblings().hide();
});

Instead of toggling the clicked element first and then hiding the others, why don't you just hide everything first and then show the clicked one? Saves you a check, and all you have to do is switch the order
$('.title').on('click', function () {
var clicked = $(this).attr('industry_id');
alert(clicked);
$('.content').hide();
$('#' + clicked).show(400);
});

Your attribute doesn't have the id selector in it. You need to do a string concatenation :
$('.title').on('click', function () {
var clicked = $(this).attr('industry_id');
alert(clicked);
$('#' + clicked).toggle(400);
$('#' + clicked).siblings().hide();
//The two last lines could be :
//$('#' + clicked).toggle(400).siblings().hide();
});
Also you have to remove the class content and title on the row since it trigger the click event and the hide part.
Here's a working fiddle : http://jsfiddle.net/dPsrL/3/

Typo on ('.title'). Should be $('.title'). Also, you should probably not give the container divs the same class as the child divs and then use that same class in your CSS and jQuery. It just makes selection more difficult.

Traversing DOM from span in / out of divs

I'm adding a click event to a span that is within a div. The target of this event, which will become visible, is a first div that is within a div, two divs down. How can I traverse the DOM to find it?
Perhaps it'll be clearer with the code:
<div a>
<h2>
<span id="here">Click</span>
</h2>
</div>
<div></div>
<div>
<div class="targetDiv">This is the div we need to find</div>
<div class="targetDiv">There are other divs with the same id, but we don't need to find those</div>
<div class="targetDiv">Not looking for this one </div>
<div class="targetDiv">Or this one either</div>
</div>
I've searched left and right and cannot find an answer. It's important to restrict the event ONLY to the first div immediately after the span.
Any help would be much appreciated.

As shown, the code would look like this:
$('span#here').on('click', function() {
$(this).closest('div').siblings(':contains(.targetDiv)').children().eq(0).show();
}

Here's a sample of the fish we caught
$(function() {
$('#here').on('click', function() {
var div = $(this) //the element clicked
.closest('div') //find nearest parent div
.nextAll(':eq(1)') //find the second next div
.children(':eq(0)') //find the first child of it
.show(); //remove invisible cloak
});
});​

This works. I provided an example you can just save to a html file and test it yourself
<style>
.targetDiv{display:none;}
</style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#here').click(function(){
$('.targetDiv').first().show(); // or whatever you want
});
});
</script>
<div a>
<h2>
<span id="here">Click</span>
</h2>
</div>
<div></div>
<div>
<div class="targetDiv">This is the div we need to find</div>
<div class="targetDiv">There are other divs with the same id, but we don't need to find those</div>
<div class="targetDiv">Not looking for this one </div>
<div class="targetDiv">Or this one either</div>
</div>
