Selecting only one child element in AngularJS with jquery - javascript

So, I had a working function in jQuery but then I decided to use Angular for my application. Just can't find the way so it adds the CSS to only one child element.
Jquery code that was working
$('.list-div').on('mouseenter', function(){
$(this).find('.client-jar').css('opacity','1');
}).on('mouseleave', function() {
$(this).find('.client-jar').css('opacity','0');
});
Current html
<ul>
<li ng-repeat="one in ones | orderBy:'-date'">
<div class="list-div">
<div class="row jar-div first-jar-div" ng-mouseover="showButton()" ng-mouseleave="hideButton()">
<div class="col-xs-7 description-div">
<p class="version">{{ one.version }}</p>
<p class="date">{{ one.date }}</p>
</div>
<div class="col-xs-5 buttons-div">
<div class="list-button client-jar">
<a class="list-link" data-toggle="modal" data-target="#myModal">create server</a>
</div>
<div class="list-button server-jar">
<a class="list-link">Server jar</a>
</div>
</div>
</div>
</div>
</li>
</ul>
And Current Angular JS
$scope.showButton = function(){
angular.element('.list-div').find('.client-jar').css('opacity','1');
};
$scope.hideButton = function(){
angular.element('.list-div').find('.client-jar').css('opacity','0');
};

I would use:
https://docs.angularjs.org/api/ng/directive/ngMouseenter
<button ng-mouseenter="hoverState = true">mouse in mouse out</button>
Then use with:
https://docs.angularjs.org/api/ng/directive/ngMouseleave
<button ng-mouseenter="hoverState = true" ng-mouseleave="hoverState = false">mouse in mouse out</button>
At this point you have a hover over and off flag. You can now pick this flag up with ng-class to set and unset a CSS class which contains your opacity stuff, and any future CSS animations etc etc:
https://docs.angularjs.org/api/ng/directive/ngClass
<button ng-mouseenter="hoverState = true" ng-mouseleave="hoverState = false" ng-class="{'opacity-class':hoverState}">mouse in mouse out</button>
No jQuery required, AngularJS is just a totally different way of going about things.
<style>
.opacity-class .client-jar{
opacity:0;
}
</style>
<ul>
<li ng-repeat="one in ones | orderBy:'-date'">
<div class="list-div">
<div class="row jar-div first-jar-div" ng-mouseenter="hoverState = true" ng-mouseleave="hoverState = false" ng-class="{'opacity-class':hoverState}">
<div class="col-xs-7 description-div">
<p class="version">{{ one.version }}</p>
<p class="date">{{ one.date }}</p>
</div>
<div class="col-xs-5 buttons-div">
<div class="list-button client-jar">
<a class="list-link" data-toggle="modal" data-target="#myModal">create server</a>
</div>
<div class="list-button server-jar">
<a class="list-link">Server jar</a>
</div>
</div>
</div>
</div>
</li>
</ul>

angular.module('App').directive('listFade', function() {
return function(scope, element) {
element.bind('mouseover', function(children) {
// YOUR ANIMATION CODE HERE
});
element.bind('mouseout', function(children) {
// YOUR ANIMATION OUT CODE HERE
});
}
})
then just add the directive to your ng-repeat markup, list-fade=""
you don't need children but its a easy way to call the children of each element. This should help you out. Then get rid of that ng-mouseover showButton();

Updating your code to use inline CSS, would be like this.
var element = document.querySelector('.list-div .client-jar');
$scope.showButton = function(){
angular.element(element).css('opacity','1');
};
$scope.hideButton = function(){
angular.element(element).css('opacity','0');
};
As in AngularJS .element documentation, it's said that you need to pass a element.
You can also use ng-class, creating a class for opacity:
<div class="client-jar" ng-class="{class: expression}"></div>
https://docs.angularjs.org/api/ng/directive/ngClass
Or use ng-show and ng-hide for display control:
<div class="client-jar" ng-show="expression"></div>
https://docs.angularjs.org/api/ng/directive/ngShow
You could even use ng-style for inline css:
<div class="client-jar" ng-style="{'opacity': '1'}"></div>
https://docs.angularjs.org/api/ng/directive/ngStyle

Multiple tippy.js tooltips with html content

I am trying to get multiple tooltips on the same page with different HTML content using tippy.js. This content varies - it might me just image or text formatted with HTML tags or text + image(s). How can I make this work?
I tried to run this code but didn't had much success
<a class="btn" href="#">Text</a>
<div class="myTemplate">
<b>Text</b> <img src="https://i.imgur.com/dLcYjue.png">
</div>
<a class="btn" href="#">Text2</a>
<div class="myTemplate">
<b>Text2</b>
</div>
<script type="text/javascript">
tippy('.btn', {
content: document.querySelector('.myTemplate')
})
const clone = document.querySelector('.myTemplate').cloneNode(true)
</script>
maybe this helps someone getting here again:
also check the documentation:
https://atomiks.github.io/tippyjs/v6/html-content/
document.querySelectorAll('button[data-template]').forEach(btn => {
tippy(btn, {
content(reference) {
const id = reference.getAttribute('data-template');
const template = document.getElementById(id);
return template.innerHTML;
},
allowHTML: true
})
})
<script src="https://unpkg.com/#popperjs/core#2.0.6/dist/umd/popper.min.js"></script>
<script src="https://unpkg.com/tippy.js#6.0.0/dist/tippy-bundle.umd.min.js"></script>
<button data-template="one">One</button>
<button data-template="two">Two</button>
<button data-template="three">Three</button>
<div style="display: none;">
<div id="one">
<strong>Content for `one`</strong>
</div>
<div id="two">
<strong>Content for `two`</strong>
</div>
<div id="three">
<strong>Content for `three`</strong>
</div>
</div>
tippy takes selector as its primary argument, You would need different ids to do this. If there are more than a couple of content tooltips/generated at runtime, I would recommend to use a common convention in setting id and using a for loop for iterating over it.
Considering, there are 2 content tooltips,
<a class="btn1" href="#">Text</a>
<div class="myTemplate1">
<b>Text</b> <img src="https://i.imgur.com/dLcYjue.png">
</div>
<a class="btn2" href="#">Text2</a>
<div class="myTemplate2">
<b>Text2</b>
</div>
<script type="text/javascript">
tippy('.btn1', {
content: document.querySelector('.myTemplate1')
})
tippy('.btn2', {
content: document.querySelector('.myTemplate2')
})
</script>

Getting id of collapsible div in Jquery and Bootstrap

I have multiple(it can be 100+) collapsible div (using bootstrap)
<div>
<a href="#id1" data-toggle="collapse">
<div class="col-lg-12">Title</div>
<div class="image">Image</div>
</a>
<div id="id1" class="collapse">
<div class="col-lg-12">Description</div>
</div>
</div>
<div>
<a href="#id2" data-toggle="collapse">
<div class="col-lg-12">Title</div>
<div class="image">Image</div>
</a>
<div id="id2" class="collapse">
<div class="col-lg-12">Description</div>
</div>
</div>
And have Jquery
$('#id1').on('show.bs.collapse', function () {
$(".image").addClass('hidden');
});
$('#id1').on('hidden.bs.collapse', function () {
$(".image").removeClass('hidden');
});
I want to add hidden class on show.bs.collapse(this is from bootstrap) and remove hidden class on hidden.bs.collapse'With the jq code above I can do this just with one div that has id1. But how can I do this independently?
Try not to subscribe on the elements by ids but by element type
$('a').on('show.bs.collapse', function () {
$(this).next().find("div.image")[0].addClass('hidden');
});
$('a').on('hidden.bs.collapse', function () {
$(this).next().find("div.image")[0].removeClass('hidden');
});
Where
$(this)
should return a pointer to the collapsed/uncollapsed element
next()
should move pointer to the next element ( div id="id1" as example)
find("div.image")[0]
will find div with class "image" and take the first found element
then you can hide the image in this block or show it without using ids
If you're using
$(".image").addClass('hidden');
this will hide all the images in all blocks (not only in that one that has been collapsed)
Id refers to one element on the DOM therefore you should use classes instead. Therefore you should select divs based on their classes.
The following is a possible solution:
<div>
<a href="#id1" data-toggle="collapse">
<div class="col-lg-12">Title</div>
</a>
<div class="some-class collapse ad-col-2">
<div class="col-lg-12">Description</div>
<div class="image"></div>
</div>
</div>
<div>
<a href="#id2" data-toggle="collapse">
<div class="col-lg-12">Title</div>
</a>
<div class="some-class collapse ad-col-2">
<div class="col-lg-12">Description</div>
<div class="image"></div>
</div>
</div>
Jquery:
$('.some-class').on('show.bs.collapse', function () {
$(".image").addClass('hidden');
});
$('.some-class').on('hidden.bs.collapse', function () {
$(".image").removeClass('hidden');
});

JQuery Parent-Child Selection

I am new to jQuery and am trying to write a script that will run through a menu list and display the correct background image based on the menu item. The menu list is going to be randomly populated so a script is necessary to load the correct image.
The problem is that the attribute where I am able to see which item the menu belongs to is not on the list item itself but on a div contained inside the list item. My question is is it possible to select a child element of the already selected element ?
E.g (the menuli a segment)
$(document).ready( function() {
$(menuli).each( function(index) {
$itemnumber = $(menuli a).attr("href");
switch($itemnumber) {
case 1:
$(this).css("background-image", "image01.jpg");
break;
}
});
});
This is more or less the script I am trying to get, where each list item is iterated through and depending on the href of the link inside the list item a background image is set to that list item.
EDIT
Here is my html:
<div id="divMenuSportGSXSports">

Yes you can, use find
var parentElement = $('#someElement');
var childElement = parentElement.find('.child'); //where .child should be your child selector
Where as example code is not clear, I just gave answer to your question.
try to change this:
$(this).css("background-image", "image01.jpg");
to this:
$(this).children("div").css("background-image", "image01.jpg");
If you want to target the direct child of the element, better to use children() than find()
Please refer to this: What is fastest children() or find() in jQuery?

Javascript click specific to ID

I have a div setup like so:
<div class="content">
<button class="show-comments" id="content1"></button>
</div>
<div class="comments-wrapper" id="comment1"></div>
<div class="content">
<button class="show-comments" id="content2"></button>
</div>
<div class="comments-wrapper" id="comment2"></div>
I have the following code:
$('.show-comments').click(function(e){
e.preventDefault();
$('.comments-wrapper').slideToggle('slow');
});
As you would assume, the code works but on a class basis. I'd like for it to open up only the .comments-wrapper of its associated id (i.e. open slideToggle comments2 if content 2 button is clicked and so on and so on).
How would I do this?
$('.show-comments').click(function(e){
e.preventDefault();
$(this).closest(".content").next('.comments-wrapper').slideToggle('slow');
});
Note that this is dependent on the .content element being immediately followed by the .comments-wrapper.
If you have access to modify the html itself, I would suggest adding a wrapper element and then doing the following to avoid the reliance on the exact order of elements:
<div class="wrapper">
<div class="content">
<button class="show-comments" id="content1"></button>
</div>
<div class="comments-wrapper" id="comment1"></div>
</div>
<div class="wrapper">
<div class="content">
<button class="show-comments" id="content2"></button>
</div>
<div class="comments-wrapper" id="comment2"></div>
</div>
$(this).closest(".wrapper").find('.comments-wrapper').slideToggle('slow');
This way, if you add an element between the .content and the .comments-wrapper it does not break the code.
You can do this:
$(this).parent("div").next('.comments-wrapper').slideToggle('slow');
This will find the related div of class .comments-wrapper and slide toggle.
And a fiddle: http://jsfiddle.net/xCJQB/
$('.show-comments').click(function (e) {
e.preventDefault();
var num = this.id.match(/\d+$/)[0];
$("#comment" + num).slideToggle('slow');
});
Demo ---> http://jsfiddle.net/7pkyk/1/
Use this context
$(this).closest('.comments').next('.comments-wrapper').slideToggle('slow');
If it is not the immediate element then you might try this as well
$(this).closest('.comments')
.nextAll('.comments-wrapper').first().slideToggle('slow');
you can add a common class to associate a button with a div.
html:
<div class="content">
<button class="show-comments group1" id="content1"></button>
</div>
<div class="comments-wrapper group1" id="comment1">1</div>
<div class="content">
<button class="show-comments group2" id="content2"></button>
</div>
<div class="comments-wrapper group2" id="comment2">2</div>
javascript:
$('.show-comments').click(function(e){
var associate = $(this).attr('class').match(/group\d+/).pop();
var selector = '.comments-wrapper.' + associate;
e.preventDefault();
$(selector).slideToggle('slow');
});

Toggle Javascript outside of parent

I have issues when trying to place an event to toggle a div using an element outside of the parent container.
I trying to target the same behavior from outside of the parent elements using a span tag.
Any help would be grateful.
HTML:
<div class='toggle_parent'>
<div class='toggleHolder'>
<span class='toggler'>Open</span>
<span class='toggler' style='display:none;'>Close</span>
</div>
<div class='toggled_content' style='display:none;width:100%;height:400px;'>
<h2>Hello This Is My Content Right Here</h2>
<span class='toggler btn btn-large'>Close</span>
</div>
</div>
<!-- I need this element to trigger from outside -->
<span class="toggler btn btn-large btn-info">Gain Early Access</span>
Javascript:
$('.toggler').live('click',function(){
/* $(this).parent().children().toggle(); //swaps the display:none between the two spans */
$(this).parent().parent().find('.toggled_content').slideToggle(); //swap the display of the main content with slide action
});
Amended your example to suit the purpose.
<div id="container">
<div>
<div>
<span class='open'>Open</span>
<span class='close' style='display:none;'>Close</span>
</div>
<div class='content' style='display:none;width:100%;height:400px;'>
<h2>Hello This Is My Content Right Here</h2>
<span class='close'>Close</span>
</div>
</div>
<!-- I need this element to trigger from outside -->
<span class="toggle">Gain Early Access</span>
</div>
$(".toggle").click( function( ) {
$(".content").slideToggle();
});
$(".open").click( function( ) {
$(".content").slideDown();
});
$(".close").click( function( ) {
$(".content").slideUp();
});
Just use a global parent div.
<div id="container">
<div class='toggle_parent'>
<div class='toggleHolder'>
<span class='toggler'>Open</span>
<span class='toggler' style='display:none;'>Close</span>
</div>
<div class='toggled_content' style='display:none;width:100%;height:400px;'>
<h2>Hello This Is My Content Right Here</h2>
<span class='toggler btn btn-large'>Close</span>
</div>
</div>
<!-- I need this element to trigger from outside -->
<span class="toggler btn btn-large btn-info">Gain Early Access</span>
</div>
And you can just do this :
var container = $('#container');
container.on('click', '.toggler', function() {
container.find('.toggleHolder .toggler').toggle();
container.find('.toggle_content').slideToggle();
});
By the way, if you use jQuery 1.7 or more, live is deprecated. See http://api.jquery.com/live/
