How to remove/add html tag in ng-repeat

is it possible to remove/add the html tag dynamically with condition in the javascript?
https://jsfiddle.net/kimsoon/Ldy9xhjt/3/
Example i need to remove the number 2 th column when button is clicked, insert back again when button is clicked. I have using this but does not work.
angular.element(document).find('.dataTable tfoot').remove($scope.items);///to remove
angular.element(document).find('.dataTable thead').prepend($scope.items);//to add

According to the Angular documentation on angular.element().find():
Note: Keep in mind that this function will not find elements by tag
name / CSS selector. For lookups by tag name, try instead
angular.element(document).find(...) or $document.find(), or use the
standard DOM APIs, e.g. document.querySelectorAll().
So, angular.element(document).find(...) can only be used lookup by tag name not class name.
Therefore, your code is not working because your .find() is not returning the element(s) you expect it to (in fact it's not returning any).
Use the DOM method getElementsByClassName to select using class name:
const dataTable = angular.element(document.getElementsByClassName("dataTable"));
Then you can perform your prepends or removals on the wrapped angular dataTable element:
dataTable.remove($scope.items); //to remove
dataTable.prepend($scope.items); //to add

Select second element by custom data/attirbute

OK. I'm trying to get elements in javascript by CSS selector. To get one by custom element I know is like 'element[custom-name="Literal name"]'.
OK. This works. But now I need to get the second one. I mean I have some elements with the exact custom-name, and for everyone I need to apply a diferent rule (tehere are only 5).
How can I select the other ones? Is posibble select them by CSS?
PS: They are located in random positions, so maybe the first one is the 5 element one time and if I refresh the page it can be the 10 element inside the container.
PS2: No, It's not possible to change the HTML in my case :( . The only code I'm alowed to change is CSS and javascript.
Thanks for reading me! :D

Assuming you can't select specific ones by another, non-order-dependent factor, you can use the pseudo-selector :nth-child. In your case, the complete CSS selector would be element[custom-name="Literal name"]:nth-child(2) - substitute the 2 for any other number as you see fit. Generally it's not the best idea to select only by position in the document, as position may change more often than attributes - but in any case, there's a pure CSS solution!
Note that this only works if the elements you're working with are the only children of a common parent element - if you're looking for the second element that matches that query in general across the entire document, there is no way to do that with a CSS selector. Instead, you can make sure to add a unique class or other differentiating attribute to each element, or simply use querySelectorAll - in that case, you could get the second element using this little snippet: document.querySelectorAll('element[custom-name="Literal name"]')[1].

How to use common js function for two divs containig elements of identical ids?

I have common jQuery function and two div tags. Both div tags have different names but both containing elements of identical ids now i want to use this common Jquery function for them both?
I have implemented common function but it's not working for both.
Here's link to my jsfiddle -jsfiddle.net/xS7zF/1/
In my jsfiddle there are two div tags namely example1 and example2 and both tags have elements of identical ids. Function is working fine for first div but not for second.
please help me to sort out this.

Yeah, under the hood, jQuery selection on an ID will use the Document.GetElementById() function implemented by the browser, which is really fast, but (i guess depending on the browser) will stop after it finds the first element, since ID's should be unique and no further searching is needed after the first one is found.
For instance, rename the divs with id="eb" to class="eb" and you can still target specific elements using $("#example1 .eb") and $("#example2 .eb")
UPDATE:
Using your new Fiddle I created this: http://jsfiddle.net/xS7zF/5/
I cleaned up a lot of code and hopefully you can see what I have done. I changed all elements that appear twice from id to class. Now, when you attach an event to an element using $(".classname").click(), it attaches to all the elements. In the handler function where you set HTML and do your show()/hide(), you don't target a specific element using it's ID, but you find it relative to the element that does the event. You can do this using parent(), parentsUntil(), next(), find(), etc. Check jQuery docs for all possibilities. So for instance, the change-handler attaches to all inputs with name=Assets. But instead of doing $("#b1").show(), I go to the parent of the specific input that fires using $(this).parent(). Then I find the element with a class=".b1", which it will only find the one that is next to this specific input and I set the HTML to just that element.
Since there is another input, the same actions happen when THAT input changes, but instead it finds IT's parent, and finds the element with class=".b1" that is next to IT. So both divs with input are contained since they act on elements relative to itself and not across the document.
For extra fun and to show you how flexible this way of programming is, here is a fiddle with the Javascript-code unchanged, but with the exact same question-div copied 8 times. No matter how many times you repeat this, the same code will act on as many divs as you create since everything works relative. http://jsfiddle.net/xS7zF/7/
Hopefully this helps, the rest is up to you!

ID's must be unique, you should not repeat them. You could replace id with class and in the jQuery function do (".ub").each() or manually referencing the object using eq(x). e.g. (".ub").eq(1).

You shouldn't assign same id's to different elements.
You CAN but you SHOULDN'T. Instead of giving the same id, use class

IDs must be unique, try fix this, change to classes.
You can try something like this:
$("div div:first-child")
instead of
$("#eb")
But depends of the rest of your page code. So, change to classes first and use
$(".eb")

when jQuery / javascript find the first ID it would ignore the rest, please read more about it

Select a div within a while of divs

How to select a div among a set of divs have the same class? these divs retrieved from a database and shown using a mysql_fetch_array while.
Coz I wanna use/edit information included within each one of these divs.
Any way of act is welcome: jquery, javascript, ..
Regards!

You can use jQuery's :eq selector and/or .eq() function (and their derivatives :first/.first(), :last/.last(), ...) to select a specific div amongst a set of divs by index, if that's what you're asking.
E.g.:
var thirdFooDiv = $("div.foo:eq(2)"); // Third one, first is 0

How to remove a JavaScript initialisation?

What I am trying to achieve is a second dropdown list to be populated with values based on the selection of the first dropdown list.
I've got it to work using the following:
http://jsfiddle.net/ydPfH/6/
The problem is that an external plug in that I am using to display images in a drop down list somehow stops this code from working properly.
The code that initalises this plug-in is $("body select").msDropDown(); and what I have below the simple search form that uses this plug-in is a jquery expandable div so you click Advanced Search to expand the form with the dynamic dropdowns.
<a href="#" rel="toggle[advancedsearch]" data-openimage="images/collapse.png" data-
closedimage="images/expand.png">Advanced Search<img id="expand"
src="images/collapse.png"/> </a>
<div id="advancedsearch">
<p>Document Properties:</p>
<form>
<select id="tags" name="tags" class="tags">
etc....
What I'm hoping for is some kind of onclick or something even easier to call to another JS method to somehow remove the $("body select").msDropDown(); initialisation or to even initialise something silly that in turn removes it.
Full source of the page can be seen here if it helps: http://jsfiddle.net/pQ9LT/
Thanks,

If I'm getting this right, here is the answer:
You should add class attributes to the <select> elements that are going to be using your msDropDown plugin. Then initialize the plugin like this $('select.yourClass').msDropDown();
where yourClass is the class name you assigned these <select> elements.
The body part in your selector is superflous.
This way, jQuery will only apply the plugin to the <select> elements "marked" with you class name and not all of them so you can use the other "normal" <select> elements without interference.
Hope I helped you out.

I'm not completely clear on what your overall requirements are and what may or may not be acceptable so where are a few thoughts that I have.
Give the select elements you do not want styled as image combo boxes a class or an id. Then use the :not() selector in combination with your msDropdown initialization
$("body select:not('.nostyle')").msDropDown(); //using the class 'nostyle' to filter out the elements that should get the image combobox
Use a more specific selector in the initialization call; this is kinda the opposite of the above
$("body select.classOfSelectsTobeStyled").msDropDown(); //using the class 'classOfSelectsTobeStyled' on elements that should get the image combobox
