Remove owl carousel item

I know that there are some associated questions about it, I tried all solutions and read all documentation, but w/o result.
I am initializing a Owl carousel :
HTML
In HTML, I have 2 items :
<div class="owl-carousel owl-theme all_diplomas">
<div class="item diploma-0">
<div class="content_diplomas">
<a data-fancybox="gallery" href="images/6.jpg"><i
class="material-icons">search</i></a>
<figure><img src="images/6.jpg" alt=""></figure>
</div>
<button class="waves-effect delete-diploma waves-blue diploma-0" type="button"><span>x</span> </button>
</div>
<div class="item">
<div class="add_diplomas">
<div class="item_add_diplomas">
<span class="plus_add">+</span>
<span class="txt_btn">Add diploma<br></span>
<input id="generateInputsForDiplomas">
</div>
</div>
</div>
</div>
JS :
$(".all_diplomas").owlCarousel({
loop: true,
margin: 15,
responsive: {
1000: {
items: 4
},
1200: {
items: 2
}
},
});
Next, after my script initialization :
$('input#generateInputsForDiplomas').on('click',function() {
var template = '<div class="item diploma-' + index + '"> <div class="content_diplomas"> <a class="diploma-' + index + '" data-fancybox="gallery" href="images/3.jpg"><i class="material-icons">search</i></a>' +
'<figure><img src="images/3.jpg" class="addedDiplomaInput diploma-' + index + '"alt=""></figure> </div> </div>'
+ '<button class="waves-effect delete-diploma waves-blue ' + classes + '" type="button"><span>x</span> </button>';
var newEl= $('.all_diplomas').trigger('add.owl.carousel', [template, 33]).trigger('refresh.owl.carousel');
});
Code above just adds a block of owl-item with one image and some id-s
and classes.
Then, it appends this template to position 33 and refreshes the
carousel
Them, each element has a delete button associated to owl-item class
$(document).on('click', 'button.delete-diploma',function() {
$(".all_diplomas").trigger('remove.owl.carousel', 33).trigger('refresh.owl.carousel');
});
That's the thing. When adding an element, from documentation, I am setting the position for this element explicitly - like 33. But when I am calling the button that is responsable to remove item with position 33, it deletes entire slider, or sometimes unexpected behavior.
The reason why I'm calling position explicitly, because I need to know each item's index, because when calling delete button, to know item with which position to delete. Documentation offers callbacks that has this information, but not for "add" event.
How can I lifehack that problem? I want to add n-items to carousel, and each this block with image to has it's own delete button. So, when calling this button, it will delete that element and refresh the Owl. I tried with pure jQuery to delete parents and so on... but Owl generates some other classes, and because of it, item is deleted, but empty spaces in slider remains.

Creating second popover within first popover

Trying to select the current user when click on the coffee button inside popover.
Users are populated in the home page.
<div class="user">
...
<div class="popover hovercard" role="tooltip">
...
<div class="info">
<div class="info-inner">
<div class="interactions">
<a class="coffee-btn btn" href="#">Coffee</a>
</div>
</div>
</div>
</div>
...
</div>
I tried to select the "closest" user but apparently it's targeting all users.
Below is the JS code:
$(document).on("click", ".interactions .coffee-btn" , function(){
$(this).parents(".popover").popover('hide');
// get user dom
var cur = $(this).closest(".user");
console.log(cur); //returns an array, not what i want
cur.css("float", "left");
// create another popover
});
Should I assign users an id instead with angular and target them that way?

Try:
$(".interactions .coffee-btn").on("click", function(){
// get user dom
var cur = $(this).closest(".user");
console.log(cur); //returns an array, not what i want
cur.css("float", "left");
});
It's working for me here.
When you use $(this), on (document), you're selecting the document, not the button.

Hide or disable drop down list menu buttons. jQuery of JavaScript.

I have a dynamically created 3 options list which are attached at the end of a table row. I want to hide or disable Edit and Copy options if certain conditions are not met when page loads. How can i do this using either jQuery of JavaScript.
<div class="btn-group ewButtonGroup open">
<button class="dropdown-toggle btn btn-small" data-toggle="dropdown" href="#">Options <b class="caret"></b></button>
<ul class="dropdown-menu ewMenu">
<li><a class="ewRowLink ewView" data-caption="View" href="teamsview.php?showdetail=&TeamID=1">View</a></li>
<li><a class="ewRowLink ewEdit" data-caption="Edit" href="teamsedit.php?TeamID=1">Edit</a></li>
<li><a class="ewRowLink ewCopy" data-caption="Copy" href="teamsadd.php?TeamID=1">Copy</a>
</li>
</ul>
</div>
I have tried the following code which deosnt work.
<script>
$(document).ready(function() {
var Week_Check = $('#ewRowLink ewView span').text();
if ( Week_Check > 10) {
$('.ewRowLink ewView').hide();
}
});
</script>

You have a bad jQuery selector. If you want to hide an element having both of those classes you want to go this way:
$('.ewRowLink.ewView').hide();
By using $('.ewRowLink ewView').hide(); you basically state: hide all ewView (?) elements that are inside other elements having ewRowLink class.

You can use .off() to unbind the event:
$('.ewEdit, .ewCopy').off('click');
or if you want to hide:
$('.ewEdit, .ewCopy').hide();
Yet you need to mention on what condition you want to do this.

<script>
$(document).ready(function() {
var Week_Check = $('#ewRowLink, #ewView').find('span').html();
if ( Week_Check > 10) {
$('.ewRowLink, .ewView').hide();
}
});
</script>

Running click functions on every instance of listing instead of current

I have a listing of articles here, and I can't figure out how to execute the ng-click function calls on every new article inside the ng-repeat. Right now it works for existing articles, but when new articles are added dynamically (via AJAX), I need those to have the same functionality too.
For example: the ng-click function calls on the "+" sign to reveal social buttons seem to not work once new articles are inserted via AJAX (ie: delete articles, and let list be populated again with new elements)
Does AngularJS provide any tools to do that?
<div>
<div>
<input type="text" ng-model="search">
<span>{{filtered.length}} article(s)</span>
</div>
<div article-listing ng-repeat="article in filtered = (wikiArticles | filter:search)">
<!--Individual article begin-->
<span>
{{article.title}}
</span>
<div>
<a ng-click="articles.removeArticle($index)" title="Delete">
<span>✖</span>
</a>
<a ng-click="articles.toggleShare(article)">
<span class="plus-sign" title="Share">✖</span>
<div social-share ng-show="article.socialShare">
<div ng-click="socialShare = !socialShare" class="addthis_toolbox addthis_default_style addthis_32x32_style"
addthis:title="{{article.title}}" addthis:description="{{article.extract}}" addthis:url="{{article.url}}">
<a class="addthis_button_facebook"></a>
<a class="addthis_button_twitter"></a>
<a class="addthis_button_google_plusone_share"></a>
<a class="addthis_button_reddit"></a>
<a class="addthis_button_hackernews"></a>
</div>
</div>
</a>
</div>
<div>{{article.extract}}</div>
<!--Individual article end-->
</div>
</div>
Code for ng-click calls that don't seem to work for new article insertions
$scope.articles = (function() {
return {
shuffleArticles : function() {
$scope.wikiArticles.reverse();
},
removeArticle : function(index) {
$scope.wikiArticles.splice(index, 1);
$scope.fireAPICalls();
},
toggleShare : function(currArticle) {
var previousState = currArticle.socialShare;
angular.forEach($scope.wikiArticles, function(article) {
article.socialShare = false;
});
currArticle.socialShare = previousState ? false : true;
}
}
})();

Your ng-click calls are actually working- you can watch the ng-show toggle in the debugger.
The problem is that there is nothing to display on the new items you add.
The articles you initially add all have their icons populated with the .addthis classes, for instance here's your Facebook icon element:
<a class="addthis_button_facebook at300b" title="Facebook" href="#">
<span class=" at300bs at15nc at15t_facebook">
<span class="at_a11y">Share on facebook</span>
</span>
</a>
at300bs includes the following css which displays the image:
background: url(widget058_32x32.gif) no-repeat left!important;
However as you add new items, you aren't including the needed .addthis classes to them. Their elements look like this:
<a class="addthis_button_facebook"></a>
So ng-show has nothing to display (it shows a 0x0 div).
Add the .addthis classes to your new elements as you add them and you'll be all set.

Combining sequential jQuery selectors into a single function

BIG EDIT: Updated the code sections, but the question remains the same.
I've got perhaps a unique jQuery issue that I could use some help on.
I've got a function (that works perfectly) that looks like this...
var openslide1 = function() {
$("#slide1").animate({
left: "+=250px",
}, 400, function() {
// Animation complete.
});
$(this).unbind('click', openslide1); \\ to prevent from pushing slide over too many times
};
$("#openslide1").click(openslide1);
My issue is there could be a potentially unlimited number of slides, and therefore "openslides". Each "openslide" selector corresponds with its own unique slide. (e.g. #openslide2 would open #slide2 and unbind #openslide2...so on and so forth).
So how do I combine these into a single variable and function?
And as a side note...I'm also going to want to "re-bind" the #openslide on the click of another event. Currently, I'm able to do them one at a time through this....
$("#closeslide1").click(function() {
$("#slide1").animate({
left: "-=250px",
}, 500, function() {
// Animation complete.
});
$('#openslide1').click(openslide1); \\ rebinds openslide1
});
But once this becomes a combined function, I'm assuming "openslide1" will no longer be the variable for the function. So how would I rebind that click event when #closeslide is clicked. (And obviously I'm going to use the first part of this question to apply to the closeslide variables as well.)
<div class="section">
<a class="edit-btn" id="openslide1" href="#null">edit</a>
<a class="edit-btn" id="openslide2" href="#null">edit</a>
<a class="edit-btn" id="openslide3" href="#null">edit</a>
<a class="edit-btn" id="openslide4" href="#null">edit</a>
</div>
<div class="slide" id="slide1">
<h1>Edit Row</h1>
<p>Prototyping data below, may not reflect link clicked.</p>
Submit <a id="closeslide1" class="btn btn-danger" style="color:#fff" href="#null">Cancel</a>
</div>
<div class="slide" id="slide2">
<h1>Edit Row</h1>
<p>Prototyping data below, may not reflect link clicked.</p>
Submit <a id="closeslide2" class="btn btn-danger" style="color:#fff" href="#null">Cancel</a>
</div>
<div class="slide" id="slide3">
<h1>Edit Row</h1>
<p>Prototyping data below, may not reflect link clicked.</p>
Submit <a id="closeslide3" class="btn btn-danger" style="color:#fff" href="#null">Cancel</a>
</div>
<div class="slide" id="slide4">
<h1>Edit Row</h1>
<p>Prototyping data below, may not reflect link clicked.</p>
Submit <a id="closeslide4" class="btn btn-danger" style="color:#fff" href="#null">Cancel</a>
</div>
PLEASE HELP!
Thanks!

I'll give it a shot, does this help you with portability?
$(".openslide1").click(function() {
openSlide(".slide1", "body", 400, ".openslide1");
});
function openSlide(target, bodyObj, speed, original) {
$(target).animate({
left: "+=250px",
}, speed, function() {
// Animation complete.
});
$(bodyObj).animate({
marginLeft: "+=250px",
}, speed, function() {
// Animation complete.
});
$(original).unbind('click');
}

Change you function to pass a reference to the element (or elements) that you want to manipulate:
var openslide = function(elem) {
var id = elem.attr("id");
$("#" + id.substring(5)).animate({
left: "+=250px",
}, 400, function() {
// Animation complete.
});
$('body').animate({
marginLeft: "+=250px",
}, 400, function() {
// Animation complete.
});
elem.unbind('click', openslide);
};
$(".edit-btn").click(function() {openslide($(this))});
Then you can use a single function for all your elements and you can bind them all at the same time if they have a common class (in this case, I called them .openslide).
Edit: looking at your original question again, I noticed that the element being animated at the start isn't the same element. But if there is an easily defined relationship between it and the element you clicked on (for example, it's a child of the original element, or the next sibling, or something) you can easily come up with the appropriate selector to select it. In the example above, I assumed a sibling relationship with the target element having a class of .targetclass, but change it as suits.
Edit 2: changed it to use the id's on the assumption that id openslide1 will correspond to the element with id slide1.

Construct the links as follows :
<div class="section">
<a class="edit-btn openslide" data-slide="#slide1" href="#null">edit</a>
<a class="edit-btn openslide" data-slide="#slide2" href="#null">edit</a>
<a class="edit-btn openslide" data-slide="#slide3" href="#null">edit</a>
<a class="edit-btn openslide" data-slide="#slide4" href="#null">edit</a>
</div>
And the slides as follows :
<div class="slide" id="slide1">
<h1>Edit Row</h1>
<p>Prototyping data below, may not reflect link clicked.</p>
Submit <a class="closeslide1 btn btn-danger" style="color:#fff" href="#null">Cancel</a>
</div>
It's hard to see exactly what effect is required but the general shape of the handler will be something like this :
$(".openslide, .closeslide").click(function() {
if($("body").filter(":animated").length) { return; } //animation in progress, abort.
var $slide = $($(this).data('slide'));
var state = $slide.data('state') || 'closed';
var sign = (state == 'closed') ? '+' : '-';
$slide.animate({
left: sign + "=250px"
}, 400, function(){
$slide.data('state', (sign == '+') ? 'open' : 'closed');
});
$('body').animate({
marginLeft: sign + "=250px"
}, 400);
return false;
});
untested
As you will see, one function (when it works) will handle both slideopen and slideclose actions.
You will have to adapt the script to achieve precisely what you want.
