Disable scrollable event on a specified id - javascript

I have a responsive navigation on my website. And, this js code is for smooth scrolling within my webpage.
$(function(){$("a[href*=#]:not([href=#])").click(function() {
if(location.pathname.replace(/^\//,"")==this.pathname.replace(/^\//,"")
&&location.hostname==this.hostname){
var target=$(this.hash);
target=target.length?target:$("[name="+this.hash.slice(1)+"]");
if(target.length){
$("html,body").animate({scrollTop:target.offset().top},1000);return false}}})});
When i create a link Scroll to Topwrapper, i can scroll it smoothly to the div as long as the div name is #topWrapper or #whatever. I have also an id name navi in my navigation. I would like to ask that, is there anyway i can disable the id in this js code so that it doesn't scroll when i click on the hamburger icon to open the menu? Thank you!
Hope you understand what i am asking as English is not my primary language. Thank you!

Js Code for navigation:
$(document).ready(function(e){
var t=$("#navi"),a=$(".menu-link"),l=$(".has-sub-menu > a");
a.click(function(e){e.preventDefault(),a.toggleClass("active"),t.toggleClass("active")}),l.click(function(e){e.preventDefault();
var t=$(this);t.toggleClass("active").next("ul").toggleClass("active")}),e.preventDefault()});

Do:
document.getElementById("desired-id-name").addEventListener('click', function(){
return false; // does nothing
});
EDIT 1:
Since you are using jQuery, here is a jQuery version:
$("#desired-id-name").click(function(){
return false;
});
Make sure to add this inside:
$(function(){ ... };
EDIT 2:
$("#desired-id-name").scroll(function(){
return false;
});

Changing structure of html menu using javascript

CMS, that I am using, generates such a code for menu:
<ul>
<li>second level menu</li>
<li>third level menu</li>
<li>third level menu</li>
</ul>
<ul>
<li>second level menu</li>
<li>third level menu</li>
</ul>
...
I would like to change the way of displaying the third level menu. Is it possible to change this code using javascript into:
<ul>
<li>second level menu
<ul>
<li>third level menu</li>
<li>third level menu</li>
</ul>
</li>
</ul>
<ul>
<li>second level menu
<ul>
<li>third level menu</li>
</ul>
</li>
</ul>
...
You need to differentiate li elements, so you can identify then, which should be first or next level elements. Setting data-attributes, I think is a not "so much bad solution".
Btw, below is only a boilerplate code, and will work verily for given structure. You need to grasp the logic - so you can apply it to other problems.
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<ul>
<li data-level="2">second level menu</li>
<li data-level="3">third level menu</li>
<li data-level="3">third level menu</li>
</ul>
<ul>
<li data-level="2">second level menu</li>
<li data-level="3">third level menu</li>
</ul>
<script type="text/javascript">
var uls = document.querySelectorAll('ul');
for(var i=0; i<uls.length; i++) {
var children = uls[i].querySelectorAll("li");
var _children = Array.from(children).filter(e=> e.dataset.level == "3");
if (_children.length > 0) {
var newul = document.createElement("ul");
_children.map(e=>newul.appendChild(e));
uls[i].appendChild(newul);
}
}
</script>
</body>

How to toggle only header element not the list

I have this function that expands the <ul> and hides it after it is pressed.But when i press on <li> it will also close or expand. How do I make it to toggle only when the the <h4> is clicked ?
$('.category ul').hide();
$('.sub').click(function() {
$(this).find('ul').slideToggle();
});
<ul class="category text-center">
<li class="sub">
<h4><b>Licenses</b></h4>
<ul class="archive_posts">
<li class="posts">Licence types and users plans</li>
<li class="posts">Adding new licence</li>
<li class="posts">Updating licence</li>
<li class="posts">Removing licence</li>
</ul>
</li>
</ul>
Thanks in advance.
Changes made
► changed $('.sub').click(function() { to $('.sub h4')
► changed $(this).find('ul') to $(this).next()
Working Demo
$('.category ul.archive_posts').hide();
$('.sub h4').click(function() {
$(this).next().slideToggle();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="category text-center">
<li class="sub">
<h4><b>Licenses</b></h4>
<ul class="archive_posts">
<li class="posts">Licence types and users plans
</li>
<li class="posts">Adding new licence
</li>
<li class="posts">Updating licence
</li>
<li class="posts">Removing licence
</li>
</ul>
</li>
</ul>
Change the binding to the h4, then target the next ul.archive_posts for sliding.
$('.category ul').hide();
$('h4').click(function() {
$(this).next('ul.archive_posts').slideToggle();
});
See it working in this JS Fiddle: https://jsfiddle.net/rwvdf8ys/1/
Hope that helps.
The problem is $('this').find('ul').slideToggle();
'this' represents the obj that is cals the function. In this case it is h4. H4 has noe ul, so you cant find it. but you can find ul on $('.sub')
Here is ann example
$('.category ul').hide();
$('h4').click(function() {
$('.sub').find('ul').slideToggle();
});
<ul class="category text-center">
<li class="sub">
<h4 id="foo"><b>Licenses</b></h4>
<ul class="archive_posts">
<li class="posts">Licence types and users plans</li>
<li class="posts">Adding new licence</li>
<li class="posts">Updating licence</li>
<li class="posts">Removing licence</li>
</ul>
</li>
</ul>
js fiddle:
https://jsfiddle.net/8hvc4cfh/
You might use the siblings('ul') selector to find and close the neighbour ul. While $(".sub h4") limits the clickable elements to your h4.
$('.category ul').hide();
$('.sub h4').click(function() {
console.log('test');
$(this).siblings('ul').slideToggle();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="category text-center">
<li class="sub">
<h4><b>Licenses</b></h4>
<ul class="archive_posts">
<li class="posts">Licence types and users plans
</li>
<li class="posts">Adding new licence
</li>
<li class="posts">Updating licence
</li>
<li class="posts">Removing licence
</li>
</ul>
</li>
</ul>
You can try this.
$('li.sub h4').click(function() {
$(this).next().slideToggle();
});

How to create new navigation bar from clicked li using jquery

This question is kind of puzzle, I know its not so easy, I would like to create new navigation link based on clicked li, for example
<nav id="nav-main">
<ul>
<li>Home</li>
<li>About</li>
<li>Gallery</li>
<li>Tutorials</li>
<li>Others
<ul>
<li>Employee Portal
<ul>
<li>Current Staff</li>
<li>Retired Staff</li>
<li>Staff Profile</li>
</ul>
</li>
</ul>
</li>
</ul>
</nav>
Suppose If I click on "Home" I would like to create new nav bar like below
<nav id="nav_others">
<ul>
<li>Home</li>
</ul>
</nav>
Same way if I click on "Staff Profile"
<nav id="nav_others">
<ul>
<li>Others
<ul>
<li>Employee Portal
<ul>
<li>Staff Profile</li>
</ul>
</li>
</ul>
</li>
<ul>
</nav>
I don't know how many parent and children elements, my navigation element will have, if anyone here knows how to achieve this using jquery or javascript please share your solutions.
Thank You
Add the following div into your code(After nav-main):
<nav id="nav_others">
<ul></ul>
</nav>
And use the following Jquery:
<script>
$(document).ready(function(){
$('.main').click(function(e){
var val = $(this).text();
$('#nav_others ul').append('<li class="prev">'+val+'</li>');
e.preventDefault();
});
});
</script>

How to open correct sublist in dropdown menu

I got a small Javascript menu problem.
I got a ul list that looks something like this.
<ul class="mainmenu">
<li class="sub-handle">
Item 1
<ul class="submenu">
<li class="sub-li">item 1-1</li>
<li class="sub-li">item 1-2</li>
<li class="sub-li">item 1-1</li>
</ul>
</li>
<li class="sub-handle">
Item 2
<ul class="submenu">
<li class="sub-li">item 2-1</li>
<li class="sub-li">item 2-2</li>
<li class="sub-li">item 2-1</li>
</ul>
</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
I got php to add submenu-i++ and that works just fine. Now I have a Javascript drop down function that looks like this.
var sub_handle = $('.sub-handle');
var sub_nav_ul = $('nav .submenu');
var sub_nav_ul_li = $('nav .mainmenu .sub-li');
$(sub_handle).on('click', function(){
sub_nav_ul.toggleClass('showing-sub');
sub_nav_ul_li.toggleClass('smooth-anchor');
});
sub_nav_ul_li.on('click', function(){
sub_nav_ul.toggleClass('showing-sub');
});
The problem is that when I press any submenu all of my submenus open. I want Javascript somehow to count like php and see if submenu-i++ is pressed only that one expand.
I hope this is clear enough otherwise make a shout and I will try to explain futher.
Thanks in advance!
Get rid of the numbers in the classes, so all the sub-menus have ths same class. Then use DOM navigation methods to find the corresponding menu items to toggle.
var sub_handle = $('.sub-handle');
var sub_nav_ul_li = $('nav .mainmenu .sub-li');
sub_handle.on('click', function() {
$(this).find(".submenu").toggleClass('showing-sub');
$(this).find(".sub-li").toggleClass("smooth-anchor");
});
sub_nav_ul_li.on('click', function() {
$(this).parent().toggleClass('showing-sub');
});
.submenu {
display: none;
}
.submenu.showing-sub {
display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="mainmenu">
<li class="sub-handle">
Item 1
<ul class="submenu">
<li class="sub-li">item 1-1</li>
<li class="sub-li">item 1-2</li>
<li class="sub-li">item 1-1</li>
</ul>
</li>
<li class="sub-handle">
Item 2
<ul class="submenu">
<li class="sub-li">item 2-1</li>
<li class="sub-li">item 2-2</li>
<li class="sub-li">item 2-1</li>
</ul>
</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
<ul class="mainmenu">
<li class="sub-handle sub-handle-1">
Item 1
<ul class="submenu">
<li class="sub-li">item 1-1</li>
<li class="sub-li">item 1-2</li>
<li class="sub-li">item 1-1</li>
</ul>
</li>
<li class="sub-handle sub-handle-2">
Item 2
<ul class="submenu">
<li class="sub-li">item 2-1</li>
<li class="sub-li">item 2-2</li>
<li class="sub-li">item 2-1</li>
</ul>
</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
var sub_handle = $('.sub-handle');
var sub_nav_ul = $('nav .submenu');
var sub_nav_ul_li = $('.submenu .sub-li');
sub_handle.on('click', function(){
sub_handle.removeClass("showing-sub");
$(this).addClass('showing-sub');
sub_nav_ul_li.toggleClass('smooth-anchor');
});
sub_nav_ul_li.on('click', function(){
$(this).parent().removeClass('showing-sub');
});
Will something like this work:
Note: I had to edit some of the html.
You are toggling the class on all the subitems. What you should do is traverse from the clicked handle to get the corresponding subitems for that. Something like this would suffice:
$(sub_handle).on('click', function(){
$(this).find(sub_nav_ul).toggleClass('showing-sub');
$(this).find(sub_nav_ul_li).toggleClass('smooth-anchor');
});
sub_nav_ul_li.on('click', function(){
$(this).closest(sub_nav_ul).toggleClass('showing-sub');
});
This is in no way the best solution to this, but it should help.

Collapsible menu has all drop down menu's expanded

I'm creating a website for a project and i'm not allowed to use frameworks (so no bootstrap), i've now run into a problem where the navigation bar when collapsed (screen width under 800px) has all the individual links expanded, rather than being in individual categories.
I've uploaded this website to
here
The Html nav bar
<nav role="navigation" id="cssmenu">
<ul>
<li class="active">Home</li>
<li class="has-sub">Courses
<ul>
<li>Digital Media</li>
<li>Web Development</li>
<li>Journalism</li>
<li class="last">Information & Communications</li>
</ul>
</li>
<li class="has-sub">Facilities
<ul>
<li>Societies</li>
<li>Jobs and Placements</li>
<li class="last">Library</li>
</ul>
</li>
<li class="has-sub">Manchester & Student Life
<ul>
<li>Travel</li>
<li>Attractions</li>
<li class="last">Nightlife</li>
</ul>
</li>
<li class="has-sub">Student Help
<ul>
<li>Finance</li>
<li>Student Union</li>
<li class="last">Assistance</li>
</ul>
</li>
<li class="last">Contact</li>
</ul>
</nav>
The Jquery script
( function( $ ) {
$( document ).ready(function() {
// Cache the elements we'll need
var menu = $('#cssmenu');
var menuList = menu.find('ul:first');
var listItems = menu.find('li').not('#responsive-tab');
// Create responsive trigger
menuList.prepend('<li id="responsive-tab">Digi-Co</li>');
// Toggle menu visibility
menu.on('click', '#responsive-tab', function(){
listItems.slideToggle('fast');
listItems.addClass('collapsed');
});
});
} )( jQuery );
The css can also be found
here
Any help will be appreciated, i'm sure its just a simple overwriting syntax, but i can't be too sure, whether it's that or if it's a scripting problem.
Thank you.
