how can i handle a self-reference in mootools?
After i made the next container visible, i would remove the clicked "remove" Button.
With Jquery i can do it throug the "this" operator.
window.addEvent('domready', function(){
$$('div.showButton').addEvent('click', function(){
// show next Container
$$('div.container').getNext().show('inline');
// remove this "showButton"
$(this).remove() // not working
});
});
<!-- container 1 -->
<div class="container">
<div class="showButton">Show next container</div>
<div class="hideButton">hide this container</div>
</div>
<!-- container 2 -->
<div class="container" style="display:none">
<div class="showButton">Show next container</div>
<div class="hideButton">hide this container</div>
</div>
You have to remember mootools is not jquery and they different in the implementation of stuff.
First the $$ function return array of elements and not element so you can't call show on an array - you have to take the element you want (usually it's the first).
Second - you can call the current element using $(this) but it's a bit unnecessary because you are already inside the element event so you just can use "this":

$$('div.showButton').addEvent('click', function(){
// show next Container
$$('div.container')[0].getNext().show('inline');
// remove this "showButton"
this.remove();
});

I have a lot of divs, they are the same but the data are differen(I use variable(array of objs) and for loop) but these details aren't important
<div class="item_wrapper">
<div class="item_wrapper_info">
<div class="left-line"></div>
<div class="subject">1</div> <== click here
</div>
<div class="additional_info"> <== display this block
some text
</div>
</div>
I want to achieve this:
If I click .item_wrapper_info div then I want to show .additional_info div
It should be probably done using this keyword.
If I click . item_wrapper_info block I want to find a div with the class name of . additional_info and make display = flex but I don't know how to trigger exactly its . additional_info div.
Probably I can click on .item_wrapper_info > . subject and then show its next neighbour
SOLUTION:
$(document).ready(() => {
$(".item_wrapper").click(function(){
var index = $(".item_wrapper").index(this); get index of a certain clicked .item_wrapper element on my page
$('.additional_info').eq(index).toggle(); using .eq toggle that certain element
});
})
It works for me
I haven't tested this code. Feel free to test it in a runnable snippet.
$(document).ready(() => {
$(".item_wrapper").click(function () {
var index = $(".item_wrapper").index(this)
$('.additional_info').eq(index).css("display","flex");
});
});
I`m trying to build a carousel/rondell with glide.js.
I want the left and right arrows to be displayed outside of the glide-track.
The carousel/rondell should be fully responsive.
Here is a picture of how it should be.
Can somebody help me with that?
Thank you!
You have to write the logic for arrows by yourself as Glide only looks for controls inside its root element.
Use a Glide API and the .go() method on previously queried HTML elements.
var nextButton = document.querySelector('#next');
var prevButton = document.querySelector('#prev');
var glide = new Glide('#glide');
nextButton.addEventListener('click', function (event) {
event.preventDefault();
glide.go('>');
})
prevButton.addEventListener('click', function (event) {
event.preventDefault();
glide.go('<');
})
glide.mount();
Visit Glide API documentation for more informations
You can now customize the buttons by CSS
let glide =new Glider(document.querySelector('.glider'), {
slidesToShow: 1,
dots: '#dots',
draggable: true,
});
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/glider-js#1/glider.min.css">
<script src="https://cdn.jsdelivr.net/npm/glider-js#1/glider.min.js"></script>
<div class="glider-contain">
<div class="glider">
<div>your first content here</div>
<div>your second content here</div>
<div>your third content here</div>
<div>your content here</div>
</div>
<button aria-label="Previous" onclick="glide.scrollItem(glide.slide-1)" >«</button>
<button aria-label="Next" onclick="glide.scrollItem(glide.slide+1)">»</button>
<div role="tablist" class="dots"></div>

I'm trying to build an SPA using jquery. I have some html (nothing special).
I just have a menu and some divs. Depending on which menu item you click, a specific div should be displayed.
I can use .show() and .hide() and make use of id's and data-attributes.
But I was wondering if there are better ways to perform this kind of functionality.
I have simplified your code to the bone to show it easier
Since your ID on the triggers kind of matches your sub-menu, I have used them to target the content. You would put the code in doc ready.
$( "#" + this.id.replace("-tab", "-menu") ) this line simply uses the clicked ID and replaces the -tab with -menu. This is done to work with your current html
var $menu = $('#menu');
var $subMenu = $('.sub-menu');
$('.menu-item').on("click", function() {
$menu.hide();
$( "#" + this.id.replace("-tab", "-menu") ).show();
});
$('.back-btn').on( "click", function() {
// hide all sub-menu, no need to be specific
$subMenu.hide();
$menu.show();
});
.sub-menu {
display: none
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="container-fluid" id="menu">
<div id="weed-tab" class="menu-item">
<p class="menu-name">Wiet</p>
</div>
<div id="indica-tab" class="menu-item">
<p class="menu-name">Indica</p>
</div>
</div>
<div class="container-fluid sub-menu" id="weed-menu">weed
<div class="back-btn">
back
</div>
</div>
<div class="container-fluid sub-menu" id="indica-menu">indica
<div class="back-btn">
back
</div>
</div>
I read that Angularjs directives require a different approach than jquery. I am new to angularjs, so it will be great if somebody can explain how to use directives for this simple example. If you click on bottom div, then it moves (re-parent) the top image to the bottom div. I could add this jquery code on ng-click... but is there a better way?
JQUERY INTENT:
$("#bottom").click(function(){
$("#myimage").appendTo("#bottom");
});
ANGULARJS:
<div ng-app="myapp">
<div data-ng-controller="mycontroller">
<div id="top" style="background-color:red;width:200px;height:200px">
<img id="myimage" src="//placehold.it/150x150">
</div>
<div id="bottom" style="background-color:green;width:200px;height:200px">
</div>
</div>
</div>
Instead of listening for a click in jQuery, you can use Angular's ng-click directive to specify a function to call when the element is clicked and you can use the ng-if directive to add/remove the image, for example...
<div ng-click="appendImage()" id="bottom" style="background-color:green;width:200px;height:200px">
<img ng-if="showImage" id="myimage" src="//placehold.it/150x150">
</div>
Then in your controller...
angular.controller('myController', function ($scope) {
$scope.showImage = false;
$scope.appendImage = function (event) {
$scope.showImage = true;
};
});
A key difference between plain jQuery and Angular is that in jQuery you have to write code to manipulate the DOM yourself (like appending the image). If you use directives properly in Angular, you simply make changes to the $scope and directives will update the DOM for you automatically
how to change properties of a parent div on hover of child div.
can it be done with pure css ?
html:
<div class="parent">
<div class="child">
</div>
</div>
css:
.parent{width:200px;height:100px;background:#cccccc;}
.child{width:200px;height:100px;background:transparent;}
Not with plain CSS you need some form of script to notify the parent that the child is being hovered(eg.):
<div id="parentId" class="parent">
<div id="childId" onmouseover="doOnMouseOver()" onmouseout="doOnMouseOut()" class="child">
</div>
</div>
<script type="text/javascript">
function doOnMouseOver() {
var parentNode = this.parentNode;
var newParentClass = parentNode.getAttribute('class') + 'child-beeing-hovered';
parentNode.setAttribute('class', parentClass);
}
function doOnMouseOut() {
var parentNode = this.parentNode;
var newParentClass = parentNode.getAttribute('class').replace('child-beeing-hovered', '');
parentNode.setAttribute('class', parentClass);
}
</script>
Note that I've added ids to your html elements so that I can get a hold of them with javascript without making the code unnecessary complex nor using a third party library like jQuery.
Note that you need also to bind onmouseout or otherwise the parent element will keep the new class child-beeing-hovered.
jQuery actually makes your job easier but you should try doing this with javascript at least once.
I hope it helps.
Is there a reason you do not want to use JavaScript or JQuery?
You could simply:
$("#child_id").hover(function (){
$(this).parent("div").addClass("some-class")
});
There is no parent selector in CSS.
You can find quite good explanation why it's not supported here: http://snook.ca/archives/html_and_css/css-parent-selectors
