Highlight single element in ng-repeat

following problem:
I am using ng-repeat to generate a list of items. If the user clicks on a special marker on my webpage above, the following function receives an event an scrolls down to the corresponding item. In addition to scrolling down I would like to highlight the item until the user moves the mouse again. My problem ist that do to this I need to manipulate the css class of one single element of my ng-repeat list. I thought it might be possible because every ng-repeat element gets its own local scope...but I don't find the solution.
Part of my directive:
//if a marker is clicked, the following code should bring the user to the corresponding item
$rootScope.$on("Scroll_to_product", function (event, args) {
product.gotoElement(args);
});
/*function which takes the class id of an html element as argument and brings
the user to the corresponding product*/
product.gotoElement = function (args) {
var elementID = 'product-' + args;
$location.hash(elementID);
// call $anchorScroll()
$anchorScroll();
}
Any help would be great,
Thanks, Hucho

I think this woking Plunker example may help you
Plunker link
$scope.idSelectedVote = null;
$scope.setSelected = function(idSelectedVote) {
$scope.idSelectedVote = idSelectedVote;
console.log(idSelectedVote);
}
.selected {
background-color: red;
}
<ul ng-repeat="vote in votes" ng-click="setSelected(vote.id)" ng-class="{selected : vote.id === idSelectedVote}">
</ul>

it almost broke my head, but finally was easy:
product.highlightFeature = function (args) {
var id = '#'+ 'feature-' + args;
var myEl = angular.element( document.querySelector( id ) );
myEl.addClass('feature-highlight');
};
It is easy and fast..; yet thanks for your help.
This might help others...
Best

get id of dropped div using dragula javascript

I am trying to update a c3.js chart using drag and drops with dragula.js, but I don't know how to get the id of the div that is dragged into a new container. My html is something like this:
<div id="collapse1" class="panel-collapse collapse">
<div id="color1" class="form-inline">1</div>
<div id="color2" class="form-inline">2</div>
<div id="color3" class="form-inline">3</div>
</div>
<div id="collapse2" class="panel-collapse collapse">
</div>
and I'm using dragula.js to drag and drop:
dragula([collapse1,collapse2]);
I am really new to jquery, but following this question, to access the id of the <div> dropped into collapse2 in I was trying to do something like this:
alert($("#collapse1.collapse2 div:first").attr("id"));
But no results. Any help would be really appreciated

Dragula has three Elements One is Source Div, Target Div and Its associated Element. Following Method Works For Me as Charm except i am Not using get() method which has version issue.
You Can Try Both.
Dragula gives you the id of dropped div, Source Div, Target Div.
const dragula = Dragula(['', '']);
dragula.on('drop', (el, target, source, sibling) => {
const elementId = $(el).attr("id");
const targetID = $(target).attr("id");
const sourceId = $(source).attr("id");
}

Can't answer the question directly because I am not familiar with dragula. However, I have used jqueryUI drag drop extensively and its a really good tool. You might want to give that framework a try.
Since you asked for an example, I dug into some of my old code. You might want to go look through the jqueryUI draggable and droppable tutorials to give you some background before looking at this. I have included parts of a function. I put little dots to show you where code has been left out. I have put <<< next the key lines for you. Notice how I use closure to make references available across different parts. Closure is soooo awesome. I abuse the death out of it, so learn how to use it if you can.
Note that once I got my drag object, that is what you are asking for. Notice how I reference the variable to my function later when I register the draggable.
Btw, notice there is also a stop drag function referenced which I don't show the definition of. If you move the declaration of the dragObject outside of startDrag then you can also see it from stopDrag since the definition of the function is "enclosed" in the outside register function.
function tapeChart_registerDraggables(parentObject,scope) {
if ((parentObject==null)||(parentObject==undefined)) {
parentObject=$jq(document.body);
}
var availablesShow = false;
var savingToServer = false;
var dragClone = null;
var startDrag = function(event, ui) {
tapeChartDraggingReservation = true;
var dragObject = event.target; <<<<<<
if (dragObject.getAttribute("unassigned")=="true") {
var is_chrome = window.chrome;
var is_safari = navigator.userAgent.toLowerCase().indexOf('safari/') > -1;
if (!is_chrome && !is_safari) {
$(ui.helper).css("margin-left", event.clientX - $(dragObject).offset().left);
$(ui.helper).css("margin-top", event.clientY - $(dragObject).offset().top);
}
}
...
// assigned rooms
if (scope!="UNBLOCKED") {
// register items in the grid
$(parentObject).find( ".NODRAGHELPER" ).draggable(
{
snap : "true",
revert : "invalid",
start: startDrag, <<<<
stop: stopDrag
}
)
.click(function(){
if ( $(this).is('.NODRAGHELPER-dragging') ) {
return;
}
// seems that the user can drop and click fast
// prevent this
if (!savingToServer) {
tapeChart_getReservation(this);
}
return false;
});
}

jQuery slideDown not working on element with dynamically assigned id

EDIT: I cleaned up the code a bit and narrowed down the problem.
So I'm working on a Wordpress site, and I'm trying to incorporate drop-downs into my menu on mobile, which means I have to use jQuery to assign classes and id's to my already existing elements. I have this code that already works on premade HTML, but fails on dynamically created id's.
Here is the code:
...
var menuCount = 0;
var contentCount = 0;
//find the mobile menu items
var submenus = $('[title="submenu"]');
if (submenus.length && submenus.parent('.fusion-mobile-nav-item')) {
console.log(submenus);
submenus.addClass('dropdown-title').append('<i id="dropdown-angle" class="fa fa-angle-down" aria-hidden="true"></i>');
submenus.each(function() {
$(this).attr("href", "#m" + menuCount++);
})
var content = submenus.parent().find('ul.sub-menu');
content.addClass('dropdown-content');
content.each(function() {
$(this).attr("id", "m" + contentCount++);
})
}
$(document).on('click', '.dropdown-title', function(e) {
var currentAttrValue = $(this).attr('href');
if ($(e.target).is('.d-active') || $(e.target).parent('.dropdown-title').is('.d-active')) {
$(this).removeClass('d-active');
$(currentAttrValue).slideUp(300).removeClass('d-open');
} else {
$('.dropdown-title').removeClass('d-active');
$('.dropdown-content').slideUp(300).removeClass('d-open');
$(this).addClass('d-active');
console.log($(currentAttrValue));
//THIS LINE FAILS
$(currentAttrValue).slideDown(300).addClass('d-open');
}
e.preventDefault();
});
I've registered the elements with the class dropdown-title using $(document).on(...) but I can't figure out what I need to do to register the elements with the custom ID's. I've tried putting the event callback inside the .each functions, I've tried making custom events to trigger, but none of them will get the 2nd to last line of code to trigger. There's no errors in the console, and when I console log the selector I get this:
[ul#m0.sub-menu.dropdown-content, context: document, selector: "#m0"]
0
:
ul#m0.sub-menu.dropdown-content
context
:
document
length
:
1
selector
:
"#m0"
proto
:
Object[0]
So jQuery knows the element is there, I just can't figure out how to register it...or maybe it's something I'm not thinking of, I don't know.

If you are creating your elements dynamically, you should be assigning the .on 'click' after creating those elements. Just declare the 'on click' callback code you posted after adding the ids and classes instead of when the page loads, so it gets attached to the elements with .dropdown-title class.
Check this jsFiddle: https://jsfiddle.net/6zayouxc/
EDIT: Your edited JS code works... There also might be some problem with your HTML or CSS, are you hiding your submenus? Make sure you are not making them transparent.

You're trying to call a function for a attribute, instead of the element. You probably want $(this).slideDown(300).addClass('d-active'); (also then you don't need $(this).addClass('d-active'); before)

Inside submenus.each loop add your callback listener.
As you are adding the class dropdown-title dynamically, it was not available at dom loading time, that is why event listener was not attached with those elemnts.
var menuCount = 0;
var contentCount = 0;
//find the mobile menu items
var submenus = $('[title="submenu"]');
if (submenus.length && submenus.parent('.fusion-mobile-nav-item')) {
console.log(submenus);
submenus.addClass('dropdown-title').append('<i id="dropdown-angle" class="fa fa-angle-down" aria-hidden="true"></i>');
submenus.each(function() {
$(this).attr("href", "#m" + menuCount++);
// add callback here
$(this).click( function(e) {
var currentAttrValue = $(this).attr('href');
if ($(e.target).is('.d-active') || $(e.target).parent('.dropdown-title').is('.d-active')) {
$(this).removeClass('d-active');
$(currentAttrValue).slideUp(300).removeClass('d-open');
} else {
$('.dropdown-title').removeClass('d-active');
$('.dropdown-content').slideUp(300).removeClass('d-open');
$(this).addClass('d-active');
console.log($(currentAttrValue));
$(currentAttrValue).slideDown(300).addClass('d-active');
}
e.preventDefault();
});
})
var content = submenus.parent().find('ul.sub-menu');
content.addClass('dropdown-content');
content.each(function() {
$(this).attr("id", "m" + contentCount++);
})
}

Turns out my problem is that jQuery is adding to both the mobile menu and the desktop menu, where the desktop menu is being loaded first when I search for that ID that's the one that jQuery finds. So it turns out I was completely wrong about my suspicions.

Link add-on SDK panel to toolbar button

The add-on SDK attaches panels to widgets as seen here. I would like to achieve the same effect using the add-on SDK with a toolbar button instead.
The toolbar button I'm using is of the type menu-button, which means that the left side is an icon and has an oncommand listener. The right side is a drop-down arrow which shows its contents on click. Here's the code to create such a button with the add-on SDK:
const doc = require('sdk/window/utils').getMostRecentBrowserWindow().document;
var navBar = doc.getElementById('nav-bar')
var btn = doc.createElement('toolbarbutton');
btn.setAttribute('id', 'hylytit');
btn.setAttribute('type', 'menu-button');
btn.setAttribute('class', 'toolbarbutton-1');
btn.setAttribute('image', data.url('resources/hylyt_off.png'));
btn.setAttribute('orient', 'horizontal');
btn.setAttribute('label', 'Hylyt.it');
btn.addEventListener('command', function(event) {
if (event.button===0) btnClick();
console.log(TAG+'button clicked');
}, false);
var panel = doc.createElement('panel');
panel.setAttribute('id', 'search-panel');
panel.addEventListener('command', function(event) {
console.log(TAG+'dropdown clicked');
}, false);
var label = doc.createElement('label');
label.setAttribute('control', 'name');
label.setAttribute('value', 'Article List');
var textbox = doc.createElement('textbox');
textbox.setAttribute('id', 'name');
panel.appendChild(label);
panel.appendChild(textbox);
btn.appendChild(panel);
navBar.appendChild(btn);
The panel above is not an add-on SDK panel, it's a XUL panel and is severely limited in that it can't be styled with CSS. On top of this, the panel's onCommand listener never fires despite the fact that the btn's onCommand fires as expected. The XUL panel shows itself when I click the dropdown button (as long as it has children), but because I can't access its click handler, I can't just create an add-on SDK panel on click.
So my question is this. Is there a way to access the toolbar button's menu portion's click handler or is there a way to append an add-on SDK panel as a child of a toolbar button?

Thanks for pointing me in the direction of arrow panels. Is there a way to place an HTML file in one rather than having to dynamically create XUL elements? The effect I'm trying to achieve is similar to the Pocket extension, which does one thing when the button part is clicked and another when the arrow is clicked. – willlma 7 hours ago
You have 900+ rep, you should know better. It is common knowledge to create another question topic rather then ask how to do something different in a comment especially after solution acceptance.
Nonetheless, this is what you do to accomplish the Pocket toolbarbutton effect. Based on code supplied by contributor above.
Ask another question and I'll move this there and you can accept my solution there.

Panels don't have an onCommand method see MDN - Panels Article
You can make your panel stylized, give it type arrow like panel.setAttribute('type', 'arrow') and then to attach to your button. I didn't give it type arrow below.
Heres the working code. Copy paste to scratchpad and set Environment > Browser then run it.
var doc = document; //to put this back in sdk do const doc = require('sdk/window/utils').getMostRecentBrowserWindow().document;
var navBar = doc.getElementById('nav-bar')
var btn = doc.createElement('toolbarbutton');
btn.setAttribute('id', 'hylytit');
btn.setAttribute('type', 'menu-button');
btn.setAttribute('class', 'toolbarbutton-1');
btn.setAttribute('image', ''); //i made this image blank because i dont have the image and im running from scratchpad
btn.setAttribute('orient', 'horizontal');
btn.setAttribute('label', 'Hylyt.it');
var panel = doc.createElement('panel');
btn.addEventListener('command', function(event) { //moved this below var panel = doc.createElement because panel needs to be crated before we write this function
//if (event.button===0) btnClick();
//console.log(TAG+'button clicked'); //what is TAG? its undefeined for me
panel.openPopup(btn);
}, false);
panel.setAttribute('id', 'search-panel');
/*
panel.addEventListener('command', function(event) {
console.log(TAG+'dropdown clicked'); //what is TAG? its undefeined for me
}, false);
*/
var label = doc.createElement('label');
label.setAttribute('control', 'name');
label.setAttribute('value', 'Article List');
var textbox = doc.createElement('textbox');
textbox.setAttribute('id', 'name');
panel.appendChild(label);
panel.appendChild(textbox);
btn.appendChild(panel);
navBar.appendChild(btn);

You can create a Toolbarbutton and Panel using the Addon SDK and some Jetpack modules. Try toolbarwidget-jplib and browser-action-jplib by Rob--W.
You can easy add a button to the toolbar and style the panel whatever you want with css / html:
var badge = require('browserAction').BrowserAction({
default_icon: 'images/icon19.png', // optional
default_title: 'Badge title', // optional; shown in tooltip
default_popup: 'popup.html' // optional
});

4 toggle buttons speak javascript to each other but none of them are good listeners- the sequel: stupidity strikes back

This is the sequel to this thread:
4 toggle buttons speak javascript to each other but none of them are good listeners
Our heros have overcome the ridiculous amount of nonsense originally presented in the fiddle http://jsfiddle.net/EjW7A/8/ (no longer available) when #nbrooks -reinvigorated by the forces of good- conquered all of the stupidly placed arrays, functions and the mammoth amount of redundant content with his solution:
http://jsfiddle.net/EjW7A/24/
We rejoin Luhring after 8 hours of poking, prodding, red bull drinking, concrete wall head-bashing at the final step of solving the epic problem of doom- implementation:
The new fiddle:
http://jsfiddle.net/Luhring/EjW7A/38/
Problem:
How can I insert the content dynamically- allowing each button to toggle it's own content while making sure the other buttons are toggled off and their content hidden? ex, if button 1 is toggled on (it is animated as if it were a 'real' pressed button), button 1s content is displayed in a gallery where the contents can be clicked to display a lightbox. when button 2 is clicked should toggle button 1 off and replace button 1's contents with its own.

New Working Demo
Anything invoking jQuery on DOM elements must be wrapped within the DOM ready function to work correctly (this is why your $('a').click() was failing. Also, normally if you see yourself creating multiple arrays that you never end up using, and still end up referencing each element directly, you're making a lot of wasted effort. I cleaned your code up a bit - take a look:
jQuery(document).ready(function($) {
//variable declaration section.
var contentArray = ['albumArt', 'logoDesign', 'UX', 'other'],
content = {}, newClassName, $selectedArray, i;
for ( i = 0; i < contentArray.length; i++) {
var className = contentArray[i];
content[className] = $('.' + className);
}
//prevent links that are clicked from going anywhere
$("a").click(function(e) {
e.preventDefault();
});
$('.workTypes').click(function() {
if ($(this).is('#centeringDiv a')) return;
$(this).toggleClass('workTypesSelected');
$('.workTypesSelected').not(this).removeClass('workTypesSelected');
$selectedArray = content[$('.workTypesSelected').attr('id')];
$('#galleryDiv').empty();
if ( $selectedArray ) {
// note creates #largeGallery elements dynamically
for ( i = 0; i < $selectedArray.length; i++ ) {
var $selected = $selectedArray.eq(i);
$('<a>').attr({
href: $selected.attr('href'),
title: $selected.attr('title'),
class: "lb_gal"
}).append(
$('<img>').attr({
id: "largeGallery"+i,
src: $selected.attr('href'),
class: "gallery cf"
}).rlightbox()
)
.appendTo('#galleryDiv')
.rlightbox();
}
}
}); // end click handler
}); //end the document ready jquery function​
