I am using an external javascript library called Jarvismenu for my knockout app menu and in order to make the menu work (collapse/expand parent menu items when clicking on them) a script needs to be executed after the menu has loaded.
The menu looks like this:
<nav>
<ul data-bind="foreach: reports">
<li>
<span class="menu-item-parent" data-bind="text:title"></span>
<ul data-bind="foreach: reportItems">
<li>
</li>
</ul>
</li>
</ul>
</nav>
How can I achieve this in knockout 3.3.0?
There is additional data you can send into your foreach binding. In your case you would be interested in the afterRender option.
Your code would look like this
<nav>
<ul data-bind="foreach: { data: reports, afterRender: functionToCallWhenReportsRendered}">
<li>
<span class="menu-item-parent" data-bind="text:title"></span>
<ul data-bind="foreach: { data: reportItems, afterRender: functionToCallWhenItemsRendered}">
<li>
</li>
</ul>
</li>
</ul>
</nav>
Here is a link to more documentation:
http://knockoutjs.com/documentation/foreach-binding.html
segFault's answer helped but afterRender apparantly runs every time an item is added to the ul. What I had to do was in the afterRender function check if the last item was added like this:
functionToCallWhenReportsRendered: function (elements, data) {
if ($('#unorderedListId').children().length === this.myItems().length) {
// Execute handler
}
}
<nav>
<ul id="unorderedListId" data-bind="foreach: { data: reports, afterRender: functionToCallWhenReportsRendered}">
<li>
<span class="menu-item-parent" data-bind="text:title"></span>
<ul data-bind="foreach: { data: reportItems, afterRender: functionToCallWhenItemsRendered}">
<li>
</li>
</ul>
</li>
</ul>
</nav>

I a working on a to make a reponsive dropdown navigation bar with vanilla JavaScript. In mobile view I want that upon click one dropdown the another should close. JavaScript here:
dropbtns.forEach(link => {
link.addEventListener("click", function(e) {
e.currentTarget.nextElementSibling.classList.toggle("showdd");
});
});
and show dropdown:
.showdd {
height: auto;
}
html code:
<div class="nav-container">
<div class="brand">
Logo
</div>
<nav>
<div class="nav-mobile"><a id="nav-toggle" href="#!"><span></span></a></div>
<ul id="nav-list">
<li>
Home
</li>
<li>
About
</li>
<li class="dropdown">
</i>
<ul class="nav-dropdown">
<li>
Web Design
</li>
<li>

</li>
<li>

</li>
</ul>

</li>
</ul>

</li>
</ul>
</nav>
</div>
full code can be find here.
So, if you want to collapse all other .nav-dropdown when one is being clicked on, you simply will need to:
Store the reference of the .nav-dropdown of the current element (for comparison later)
Toggle its class (as you're doing already)
Go through all other .nav-dropdown in your DOM tree and iterate through them. If they do not match the current reference, then you know the dropdown belongs to another link and you can remove the class
With that in mind we arrive at the code below:
dropbtns.forEach(link => {
link.addEventListener('click', e => {
const ownDropdown = e.currentTarget.nextElementSibling;
ownDropdown.classList.toggle('showdd');
document.querySelectorAll('.dropbtn + .nav-dropdown').forEach(el => {
if (el !== ownDropdown)
el.classList.remove('showdd');
});
});
});
It works on your Codepen after I edit the following line.
links.forEach(link => {
link.addEventListener("click", function(e) {
links.forEach(link => {
link.nextElementSibling.classList.remove("showdd"); // Here
});
e.currentTarget.nextElementSibling.classList.toggle("show");
});
});
By the way, what is "showdd"?
I need to loop through the DOM with JQuery, and add a click handler to multiple parent elements that contain a child that will also be given a slideToggle(). I have the logic working fine when I add the click handlers manually, but now I need to be able to dynamically do this to multiple parent elements.
Here is my HTML:
<div class="map-poi-nav">
<ul class="map-poi-nav-dropdown">
//Parent #1
<li class="sub-menu-link" id="sub-menu-link-1">
<a href="#">
<img src="https://svgshare.com/i/ADc.svg"> Activities
</a>
</li>
<li class="sub-menu">
<ul class="sub-menu-list" id="sub-menu-list-1">
<li><a><span>•</span>Golden State Park</a></li>
<li><a><span>•</span>Sunrise Oaks City Park</a></li>
</ul>
</li>
</ul>
<ul class="map-poi-nav-dropdown">
//Parent #2
<li class="sub-menu-link" id="sub-menu-link-2">
<a href="#">
<img src="https://svgshare.com/i/ADc.svg"> Dining
</a>
</li>
<li class="sub-menu">
<ul class="sub-menu-list" id="sub-menu-list-2">
<li><a><span>•</span>The Loft Grill</a></li>
<li><a><span>•</span>Fish Grill & Bar</a></li>
</ul>
</li>
</ul>
</div>
Basically, you click on .sub-menu-link to slideToggle() .sub-menu-list.
Here is the JS that I have working so far. It targets the id's manually currently, which feels gross:
$('#sub-menu-link-1').click(function() {
$('#sub-menu-list-1').slideToggle(100);
$(this).toggleClass('active-menu-link');
});
$('#sub-menu-link-2').click(function() {
$('#sub-menu-list-2').slideToggle(100);
$(this).toggleClass('active-menu-link');
});
My apologies if this is something very apparent to do in JQuery. I am not at all familiar with it, and it just so happens to be a requirement of this project.
you could simply use below code.
select all list items with class name and add listener. click will be attached to all elements
$('.sub-menu-link').click(function() {
$(this).slideToggle(100);
$(this).toggleClass('active-menu-link');
});
You already have classes, so just use them instead of the ids: use this to refer to the clicked element, .next() to get the next sibling (the li.sub-menu), and .find('.sub-menu-list') to get to the ul you want to toggle:
$('.sub-menu-link').click(function() {
const $subMenuList = $(this).next().find('.sub-menu-list');
console.log($subMenuList.text().trim());
$subMenuList.slideToggle(100);
$(this).toggleClass('active-menu-link');
});

You can use jQuery's .next() like so:
$(".sub-menu-link").click(function() {
$(this).next(".sub-menu-link").slideToggle(100);
$(this).toggleClass("active-menu-link");
})
Or you can chain them and use ES6 arrow syntax to make it more concise:
$(".sub-menu-link").click(() => $(this).toggleClass("active-menu-link").next(".sub-menu-link").slideToggle(100));
You should try this if your list and link ids have similiar pattern as in the code you have shown
$('#sub-menu-link').click(function() {
var id = $(this).attr("id").replace("sub-menu-link", "")
$('#sub-menu-list-'+ id).slideToggle(100);
$(this).toggleClass('active-menu-link');
});
I am creating a webpage using smart admin.I am getting left menu datas from an array.I need display menus and sub menus properly based on parent Id of each data using angular. But I don't know how to do it.Can anyone help me?please.
Script:
var app = angular.module('myApp', []);
app.controller('myController', ['$scope', '$http', function ($scope, $http) {
$scope.Menus = [];
$http.get('/list/GetSiteMenu').then(function (data) {
$scope.Menus = data.data.data.record;
}, function (error) {
alert('Error');
});
}]);
Html:
<nav ng-repeat="menuData in Menus">
<ul>
<li>
<ul>
<li><a></a></li>
</ul>
</li>
</ul>
</nav>
console.log($scope.Menus) will be in this format:
Need to iterate over menuData.menu_roles
<nav ng-repeat="menuData in Menus">
<ul>
<li>
<ul>
<li ng-repeat ="subMenu in menuData.menu_roles">
<a></a>
</li>
</ul>
</li>
</ul>
</nav>
You can use something like this according to your json
Use rootscope instead of scope to store Menus
<section class="sidebar">
<!-- sidebar menu: : style can be found in sidebar.less -->
<ul class="sidebar-menu">
<li class="{{menuItem.LiCssClass}}" ng-repeat="menuItem in $root.menuList" ng-class="{active:isActive('{{menuItem.NavigationURL}}')}">
<a ng-href="{{menuItem.NavigationURL}}" ng-click="sidebar()">
<i class="{{menuItem.ICssClass}}"></i>
<span class="{{menuItem.SpanCssClass}}"> {{menuItem.DisplayName}}</span>
<i class="{{menuItem.TreeViewIcon}}"></i>
</a>
<ul class="{{menuItem.UiCssClass}}">
<li id="{{subMenuItem.TagName}}" ng-repeat="subMenuItem in menuItem.SubMenu" ng-class="{active:isActive('{{subMenuItem.NavigationURL}}')}">
<a ng-href="{{subMenuItem.NavigationURL}}">
<i class="{{subMenuItem.ICssClass}}"></i><span>{{subMenuItem.DisplayName}}</span>
</a>
</li>
</ul>
</li>
</ul>
</section>
You can use ng-bootstrap-submenu
https://www.npmjs.com/package/ng-bootstrap-submenu
It's a module for add submenus items to parent menu items and it's easy to use
how to add javascript function to a class of active ??
I do not understand completely about javascript.
if i click menu its like remove and add new class nav active.
<div id="sidebar">
<ul id="mainNav">
<li id="navDashboard" class="nav active">
<span class="icon-home"></span>
Beranda
</li>
<li id="navPages" class="nav">
<span class="icon-document-alt-stroke"></span>
Data Profil
<ul class="subNav">
<li>Peta Lokasi</li>
<li>Site Plan</li>
</ul>
</li>
You can use something like this:
$(selector).click(function(){
$(this).removeClass(your class)
.addClass('active');
});
You have to define the selector you want to do something.
Basically i want to click on a tab and a drop down menu appears then when you re-click the same tab or any of the others I want it to hide that tab/show the other tab if clicked on the same/other tab.
I tried
$('.click').click(function() {
$(this).find('.sub-nav-list').toggleClass('active');
});
and tried
$('.click').click(function() {
$('.sub-nav-list').removeClass('active');
$(this).find('.sub-nav-list').toggleClass('active');
});
but cant work it out! any insight? Thanks
html:
<nav class="secondary-nav">

I can see at least two possible issues there.
1) sub-nav-list is not a children of click element. If they are on the same level something like that might work:
$('.click').click(function() {
$(this).parent().find('.sub-nav-list').toggleClass('active');
});
2) You have these elements generated dynamically - so you need use on with selector of any parent element that exists before you dynamically generate your sub-menus (let say nav-list):
$(".click").on("click", ".nav-list", function() {
$(this).parent().find('.sub-nav-list').toggleClass('active');
});
