Widget design in angularjs - javascript

In the past week I am trying to learn Angular JS. I mostly used jQuery on my projects so I am having hard time trying to get its concept. I decided to make a simple admin panel using angularjs for myself to use it on my projects. With this, I can learn angular while trying to to things. But I couldn't find a correct way to do it Since its completely new concept then jQuery.
Here is what I try to do:
I have a header bar on my page. In this header page there is some links (with dropdowns) like notification panel, user profile links, search panel. I called each of them widgets.
Here is my header bar html code:
<header class="bg-dark dk header navbar navbar-fixed-top-xs">
<div class="navbar-header aside-md">
<img src="images/logo.png" class="m-r-sm">Notebook
</div>
<ul class="nav navbar-nav hidden-xs">
<li dropdown>
<a href="" class="dropdown-toggle" dropdown-toggle>Activities</a>
<section class="dropdown-menu">
<p>Some activities</p>
</section>
</li>
</ul>
<ul class="nav navbar-nav navbar-right m-n hidden-xs nav-user">
<li class="hidden-xs" dropdown>
<a href="" class="dropdown-toggle" dropdown-toggle>
<i class="fa fa-bell"></i>
<span class="badge badge-sm up bg-danger m-l-n-sm count">2</span>
</a>
<section class="dropdown-menu aside-xl">
<p>some notifications</p>
</section>
</li>
</ul>
</header>
As you can see. there is two ul.navbar-nav one is left widget area, other is right widget area. What I want to accomplish is make these areas modular.
when I create a new directive for header-bar, I want it to automaticly update the header-nav. I mean each <li/> will be a directive and will have its on purposes. (eg. activity widget, notifications widget, user widget, search widget etc.)
What I think about this patern:
A controller that holds in its scope the widget lists
2 Directives for left widget area and right widget area that watches changes on the controller scope's widget list and adds to its area.
A service for widget directives that helps them to add themselves to controller scope's widget list.
I thinked that there should be a priority option that lets widgets to order accordingly.
I don't know if this design pattern is right. Also I am not exactly know how to do them. Could you please tell me if this pattern is right. Also could you write a mini angular code that accomplish what I trying to do. I am sure alot of people will use that code when they try to learn AngularJS.

How to keep submenu opened after page load in JavaScript

I have almost done my work and my client ask for keeping submenu opened when user click the item in the menu and also set active color. The idea is better orientation when user actualy is. In React App it wouldn't be problem, cuz whole app works like single page. In this case i've decided use only HTML/JS as my challenge.
Is it even possible somehow keep menu opened/open again menu when new page is loaded please?
I tried make from this app something like single page app by some tutorials like "load paghe without refresh" etc, but nothing worked.
menu
<div class="menu">
<div class="item">
<a class="sub-btn">
Matice
<i class="fas fa-angle-right dropdown"></i>
</a>
<div class="sub-menu">
<a
href="/pages/matice/zakladni-operace.html"
id="matice/zakladni-operace"
onClick="reply_click(this.id)"
class="sub-item">

</a>
<a
href="/pages/matice/hodnosti.html"
id="matice/hodnosti"
onClick="reply_click(this.id)"
class="sub-item">

</a>
<a

You can try to get window.location.href on load of your page and add style classes depending on conditionally with something like
<div class="<%= 'yourStyleClass' if #url== 'urURL' %>"> to set active color
You could use AJAX to call the page. But that doesn't sound like what you want. An alternative way in javascript would be to get the current window.location.href when the page loads, then inject a class name into the relevant node, and have the css for that class make it visible and highlighted.
If you're using a library like jQuery this shouldn't be too hard to achieve.

Dynamic css multi column layout - update columns / force reflow?

TLDR: Can I force a column layout refresh after dynamically updating the 'css-column' css with javascript/jquery?
I have a navigation menu that I am using css columns for (I cannot work out how to use the Magento2 menu column functionality). I cannot really change the markup much. I want to stop 'widow' titles from happening (titles at the bottom of the column, with all the content on the next column - see 3rd pink title in screenshot below). It cannot be set with css as the nav items are dynamic and will change.
(I have tried "break-after:avoid" on the parent list, but this stops the list from breaking altogether - i.e. it should be able to break anywhere in the middle of the list).
I came up with a hacky solution that almost works - with javascript I am dynamically adding "break-before: column" to any list that has a widow title. (It checks the left offset of the title, compared with the offset of the first list child. If it is different then it means the title starts on the previous column).
This (sometimes) works BUT it (sometimes) does not update the columns until you resize the screen a bit.
I have been been trying out these kinds of solutions and many of these too. However none of them seem to work, for example I have tried:
console.log(elt.offsetHeight);
console.log(elt.getBoundingClientRect());
Tried 'elt' being all sorts, the parent elements, the whole body/doc wrapper etc. I thought maybe this was because the element in question is hidden until you hover over the nav link. But I forced it to be open using chrome devtools and ran the same 'reflow triggering' javascript and it still made no difference?
Is there a (preferably nice and not forcing reflow of the whole document every pageload??) way to force a recalculation of the css columns?
OR is a better solution possible using css grid / any other way?
Thanks!
In case it is relevant to another possible solution, the markup is like this:
<ul class="level0 submenu">
<li class="navigation_item__back hidden-desktop">
Back
</li>
<li class="navigation_item__link hidden-desktop">
Title
</li>
<li class="level1 nav-3-1 category-item first parent">
<a href="">
<span>Sub Title</span>
</a>
<ul class="level1 submenu">
<li class="navigation_item__back hidden-desktop">
Back
</li>
<li class="navigation_item__link hidden-desktop">
Sub Title
</li>
<li class="level2 nav-3-1-1 category-item first">
<a href="/">
<span>Lorem 1psum</span>
</a>
</li>
<li class="level2 nav-3-1-2 category-item">
<a href="/">
<span>Lorem 2psum</span>
</a>
</li>
</ul>
</li>
...
</ul>

Hello all, currently trying to learn basic JQuery. I have managed to create a simple navigation bar, with responsive burger menu that hides and shows each navigation bar based on screen size. I then created a burger div that is 100% screen size fixed when displayed but is currently set it display:none. Now i have got my toggle working to display it, but when i try to close the menu bar, it doesn't seem to toggle back. Any help would be great thankyou.
My Jquery script is as follows:
<script>
$(document).ready(function(){
$("#toggleburger").click(function(){
$(".menu").toggle();
});
});
</script>
i guess your problem is that you're using an anchor tag with empty href attribute.
try chaging in
<i class="fa fa-times x3" aria-hidden="true"></i>
see example in this FIDDLE
I'm getting directed off when I click the element you're trying to tie the click event to.
Here's a working fiddle: https://jsfiddle.net/p85kazv0/
I've simply prevented the a element you're using from its default action (which is of course to direct someone to another location, dictated by whats in the href=""):
$("#toggleburger").click(function(e){
e.preventDefault();
$(".menu").toggle();
});
Reasons for unexpected behaviour:
<a> has href set to some other page. If you have to implement the menu or buttons that are only for in page activity you should set it as href="#". Meaning do not redirect me anywhere just perform the event linked with this action, which in your case is toggling of another div.
While e.preventDefault() is a workaround, it is not recommended here as the link is sitting there doing nothing. It would suit more if say you had a form that would submit itself but you wanted to do some processing/sanitation before submitting, thereby overriding default action with your logic.
There are two elements with id=toggleburger. Keep your id unique on one html page. This can give you a lot of pain while debugging.
Here is a working fiddle, I have replaced the hamburger image with text "ToggleBurger".
Set the href attribute of the <a> element equals to #:
<li><a href="#" id="toggleburger">

Update a partial in dust.js without touching the rest of the template

I'm experimenting around with dust.js and am wondering about the most efficient way to solve this:
I have a simple template structure with 2 levels of navigation and content.
The first level of navigation is static - while the second level (the subnavigation) changes with each change in the primary navigation.
Parent Template:
<nav class="navbar navbar-fixed-top navbar-dark">
<div class="container">
{>"navigation/navigation_primary"/}
{>"navigation/navigation_secondary"/}
</div>
</nav>
<div class="container"></div>
Primary Navigation Template:
<div class="navbar-container navbar-primary">
<ul class="nav navbar-nav">
{#navigation_primary}
<li class="nav-item">
<a class="nav-link" href="#{slug}">{label}</a>
</li>
{/navigation_primary}
</ul>
</div>
Secondary Navigation Template:
<div class="navbar-container navbar-secondary">
<ul class="nav navbar-nav">
{#navigation_secondary}
<li class="nav-item">
<a class="nav-link" href="#{slug}">{label}</a>
</li>
{/navigation_secondary}
</ul>
</div>
Now, my problem is this: Without reloading the page, I'ld like to update the "secondary navigation", when I click on the primary navigation elements.
The way I'ld do this, is to re-render the "Secondary Navigation Template" and then replace the old ".navbar-secondary" with the newly rendered template ( with jQuery.html() ) - but I was wondering if dust.js has it's own feature for this, since it's able to load partials asynchroneusly?
To be honest, I didn't find most of the dust.js documentation very informative, so I'm having a hard time figuring the details out.
Is there a better way to update only a partial and leaving the rest of the template untouched, without using something like jQuery.html() and replace the partial in dust.js?

make content slide in and out when clicking link?

I am green in this area and I am trying to learn while I build a virtual resume for a website I can use to advertise my programming services (my strength lies more with C#, Java and similar languages :')
Something I think would look pretty cool, is if when you click on a link in my side-bar, the content on the page slides out and is replaced with the content on the new page that slides in, in the previous page' place.
I am a bit lost on how to achieve this though and if I have to do a per-page thing, or if I can make one general method in Javascript to take care of it. I am using jQuery and bootstrap.
var main;
main = function () {
$(".sidebar-nav a").click(function() {
<!-- Not sure what to do here -->
<!-- Pseudo Code -->
<!-- find out what element was pressed
slide out content on current page using animate();
slide in content from the element that was pressed using animate(); -->
})
}
$("document").ready(main);
The HTML:
<div id="wrapper">
<!-- Sidebar -->
<div id="sidebar-wrapper">
<ul class="sidebar-nav">
<li class="sidebar-brand">
<h1>Brand</h1>
</li>
<li>
<a href="#">
Index
</a>
</li>
<li>
<a href="#">
About Me
</a>
</li>
<li>
<a href="#">
Resume
</a>
</li>
<li>
<a href="#">
Contact
</a>
</li>
</ul>
</div>
<!-- Content -->
<div id="page-content-wrapper">
<div class="container-fluid">
<div class="row">
<div class="col-lg-12">
<h1>h1</h1>
<h2>h2</h2>
<h3>h3</h3>
<h4>h4</h4>
<h5>h5</h5>
<h6>h6</h6>
<p>Grumpy wizards make toxic brew for the evil Queen and Jack.</p>
Toggle Menu
</div>
</div>
</div>
</div>
</div>
Let me know if you need the CSS.
You should use an AJAX technology to seamlessly load another page's HTML contents inline into the document.
The best choice (in my opinion) for this situation is the jQuery function load(), due to it's simplicity and pure convenience. You can also send a callback function, it's easy to implement.
You could then easily implement a CSS animation using the animation attribute.
