To add class="current" Dynamically - javascript

I have Menu list which contains Sub-Menu as shown in the code below.
<li class="current">
<span class="icon4"></span>Subscriptions
<ul class="sub-menu">
<li>View Subscriptions
</li>
<li class="#((ViewBag.PageName == " Subscription ") ? "active " : " ")">Manage Subscription Plans
</li>
</ul>
</li>
<li class="current">
<span class="icon5"></span>Administration
<ul class="sub-menu">
<li class="#((ViewBag.PageName == " AssetPage ") ? "active " : " ")">Assets
</li>
<li>Configure Text
</li>
<li>Error Log
</li>
<li>Product Settings
</li>
</ul>
</li>
<li class="current">
<span class="icon6"></span>Promo Codes
<ul class="sub-menu">
<li>Manage Promo Code
</li>
<li>Used Promo Code
</li>
</ul>
</li>
Here Subscription,Administration,Promo Codes are Menu Lists which contains Sub-Menu Lists under them.
The thing is I want to apply class=current dynamically when a user clicks on Subscription,Administration,Promo Codes`.
And I am doing this in LayoutPage of MVC.
Any help will be appreciated.

Here you have a working solution: https://jsfiddle.net/c4h3sup9/
You have to use a little bit of Javascript for that.
You have to give the listitems a other class name like in my example "operator"
document.body.addEventListener("click", function(e){
if(e.target && e.target.className == "operator"){
var actives = document.getElementsByClassName("active");
actives[0].setAttribute("class", "operator");
e.target.setAttribute("class", "active");
}
});
for this example you need to assing one element as active from the beginning.
Note:
LI elements are never parents of UL.
The order is:
Unordered List (Plural) -> List item (Singular, Child).
You might want to correct that as it is not standard conform.

To add the class name to the parent <li> element, give the main links a class name. Assuming you also want to remove it from any <li> elements that already have it, also give them a class name
<li class="container">
<span class="icon4"></span>Subscriptions
and the script will be
$('.mainmenu').click(function() {
$('.container').removeClass('current'); // remove any previous
$(this).closest('.container').addClass('current');
});
In addition, if when you navigate to one of the views with this layout, and what to add the class name to the appropriate element, then you can give the <li> elements an id attribute
<li id="subscriptions" class="container">
....
</li>
<li id="administration" class="container">
....
and in the GET method, pass the value of the id to the view (e.g. using ViewBag
public ActionResult ConfigureText()
{
ViewBag.Menu = "administration";
....
return View(...);
}
and add a script that runs when the page first loads
var menu = '#ViewBag.Menu";
$('#' + menu).addClass('current');

How to target a specific element from a group of them having the same class/id in javascript?

I want to copy the text in the <li> tag using JavaScript. It should be copied when the <li> tag is clicked. All <li> tags have the same class as they will get the same formatting through CSS.
As per my research, we need to specify the button a target class which it will copy to clipboard(Using clipboard.js). The <li> tag will be generated through js so, to give different id to each one of them will be difficult and will increase the code and reduce the speed too.
So how can copy the text of the li tag that is being clicked through js/jquery/clipboard.js etc.
<ul>
<li class="data">Lorem ipdolor.</li>
<li class="data">Lo ripsum dolor.</li>
<li class="data">Lorepsum dor.</li>
</ul>
There are different methods but two that stand up on top.
$(function() {
$("li[class='data']").click(function(e) {
// 1) Use this reference
console.log("1: " + $(this).text());
// 2) Use Event Target
console.log("2: " + $(e.target).text());
})
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
<li class="data">Lorem ipdolor.</li>
<li class="data">Lo ripsum dolor.</li>
<li class="data">Lorepsum dor.</li>
</ul>
You can put an id on ul:
<ul id="dataContainer">
<li class="data">sometext</li>
<li class="data">sometext1</li>
<li class="data">sometext2</li>
<li class="data">sometext3</li>
</ul>
Then:
document.getElementById('dataContainer').addEventListener('click', function(e){
console.log(e.target.innerText);
});

Loop through DOM elements with JQuery to assign a click handler

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');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<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>
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');
});

Make all direct parent list entries selected in mmenu

I'm working on a project where I'm about to use the jQuery plugin mmenu (http://mmenu.frebsite.nl/).
I already had to do some customisations to fit my needs but I don't know what to do with my current issue. In mmenu, when i click on an list entry I will be navigated to the given href and the clicked item becomes active by mmenus css class ".mm-selected". So far so good.
Now I want to additionally mark the parent list item (and thats parent, and so on until menu root) as selected. This should be so when the user goes one level up in the menu he should be able to see in which category he currently is.
Below is an example of the menus html structure after mmenu was applied. This shows the code for a menu with 4 main pages (index, page1, page2 and page3) and 3 subpages (2.1, 2.2, 2.3).
<nav id="nav" class="mm-menu mm-horizontal mm-offcanvas mm-hasheader mm-current mm-opened">
<ul class="mm-list mm-panel mm-opened mm-current" id="mm-0">
<li class="mm-selected">
Index
</li>
<li>
Page 1
</li>
<li>
<a class="mm-subopen mm-fullsubopen" href="#mm-1"></a>
<span>Page 2</span>
</li>
<li>
Page 3
</li>
</ul>
<ul class="mm-list mm-panel mm-highest" id="mm-1">
<li class="mm-subtitle">
<a class="mm-subclose" href="#mm-0">Page 2</a>
</li>
<li>
Page 2.1
</li>
<li>
Page 2.2
</li>
<li>
Page 2-3
</li>
</ul>
</nav>
It would be great if you had some idea where and how I could achive such functionality.
So, for the moment I did some jQuery hacking. This seems to work for my case mentioned above. It should also work for deeper menus as it's using recursion. If there's a better way to achieve this, please let me know.
var nav = $("#nav");
nav.find("li > a:not(.mm-subopen)").click(function () {
nav.find("li.active").removeClass("active");
selectParentEntry($(this));
});
var selectParentEntry = function (a) {
var li = a.parent(),
ul = li.parent(),
back = ul.find("li > a.mm-subclose").first(),
cID = "#" + ul.attr("id"),
pID = back.length ? back.attr("href") : null;
li.addClass("active");
if (pID != null) {
var subOpen = nav.find("ul" + pID + " > li > a.mm-subopen").filter(function () {
var self = $(this);
if (self.attr("href") === cID) return self;
}).first();
if (subOpen) selectParentEntry(subOpen);
}
};

Bouncing submenu jquery

I´m doing a menu that every item has it´s submenu. this is the markup:
<ul id="menu">
<li>
TITLE 1
<ul class="submenu">
<li>
sub1
</li>
<li>
sub2
</li>
</ul>
</li>
<li>
TITLE 2
<ul class="submenu">
<li>
sub1
</li>
<li>
sub2
</li>
</ul>
</li>
<li>
TITLE 3
</li>
<li>
TITLE 4
</li>
</ul>
css
.submenu{display:none}
script
function show_submenu(that) {
$('ul.submenu').slideUp();
$(that).next('ul.submenu:first').slideDown();
}
The problem I have is that if I click over an item, it slides down it´s submenu, BUT if I click over it again, it slidesup and slidesdown again it´s submenu, which is already opened... kind of weird effect for the user... any ideas how to fix it?
You need to check whether the existing submenu is visible already. If it is, you don't want to slide it down again.
var $submenu = $(that).next('ul.submenu:first'),
viz = $submenu.is(":visible");
$('ul.submenu').slideUp();
if (!viz) {
$(that).next('ul.submenu:first').slideDown();
}
http://jsfiddle.net/ExplosionPIlls/zep6H/
use toggle in jquery
$('#foo').toggle(showOrHide);
http://api.jquery.com/toggle/
It's doing exactly what you coded it to do. Instead, use .slideToggle();
function show_submenu(that){
$(that).next('ul.submenu:first').slideToggle();
}
jsFiddle example
this should help
function show_submenu(that){
if(!$(that).next('ul.submenu:first').is(":visible")){
$('ul.submenu').slideUp();
$(that).next('ul.submenu:first').slideDown();
}
}

jQuery - Building a tree style list

My DOM is as follows
<ul>
<li id="Browse">
Browse
<ul id="browse-one">
</ul>
</li>
</ul>
My jQuery in a in the bottom of the page is:
$("#Browse").click(function() {
$("#browse-one").html('<div class="ui-widget">Loading...</div>');
$("#browse-one").load('../api/browse.php?do=getFirst');
});
This script goes into the database and spits out raw LIs. After this runs the DOM is modified as follows
<ul>
<li id="Browse">
Browse
<ul id="browse-one">
<li id="one-1" data-id="1">SOMETHING</li>
<li id="one-2" data-id="2">SOMETHING</li>
<li id="one-3" data-id="3">SOMETHING</li>
<li id="one-4" data-id="4">SOMETHING</li>
.
.
.
<li id="one-N" data-id="N">SOMETHING</li>
</ul>
</li>
</ul>
What is the proper jqueryish way to track clicks on these LIs. I want to extract the data-id of the clicked element and make a second API call to construct part two of the tree. For example if data-id="1"'s LI is clicked the DOM should be:
<ul>
<li id="Browse">
Browse
<ul id="browse-one">
<li id="one-1" data-id="1">SOMETHING
<ul id="Something Here">
<li id="two-1" data-id="1">HMM</li>
<li id="two-2" data-id="2">HMM</li>
<li id="two-3" data-id="3">HMM</li>
.
.
.
<li id="two-M" data-id="M">HMM</li>
</ul>
</li>
<li id="one-2" data-id="2">SOMETHING</li>
<li id="one-3" data-id="3">SOMETHING</li>
<li id="one-4" data-id="4">SOMETHING</li>
.
.
.
<li id="one-N" data-id="N">SOMETHING</li>
</ul>
</li>
</ul>
Im having trouble thinking of how i'de keep each of the inner UL's IDs unique. Sure I can do the "LEVEL-ID" as in "two-1" but I feel this is hackish and not the proper jquery way.
EDIT:
But now how do I track the children's clicks?? This doesn't seem valid but I hope you understand wht I'm trying to do
$("#Browse").click(function() {
$("#locations-browse").html('<div class="ui-widget">Loading...</div>');
$("#locations-browse").load('../api/browse.php?do=getFirst');
//Child is tracked
$("#locations-browse").delegate("li","click",function(evt){
var inner = $(this).append("<ul></ul>");
inner.html('<div class="ui-widget">Loading...</div>');
inner.load('../api/browse.php?do=getSecond');
$(this).delegate("li","click", function(evt) {
alert("Child ". $(this).data("id") . " is clicked";
});
});
});
EDIT 2:
Hmm this still is not working:
$("#Browse").click(function() {
$("#locations-browse").html('<div class="ui-widget">Loading...</div>');
$("#locations-browse").load('../api/browse.php?do=getFirst');
//Child is tracked
$("#locations-browse").delegate("li","click",function(evt){
$(this).append("<ul></ul>");
$(this).children("ul").load('../api/browse.php?do=getSecond?location-id='.$(this).data("id"));
$(this).delegate("li","click", function(evt) {
alert($(this).data("id"));
});
});
});
Delegate the event via li#Browse and reference the data-id attribute relative to the event's contextual element.
$('#Browse').on('click', 'li', function(evt) {
alert($(this).data('id'));
});
Incidentally, there's several out-of-the-box plugins that do what you need, just in case you didn't want to build you own, e.g. YUI Treeview or the one I wrote.
