I have a simple javascript problem that I can't seem to solve.
I want to make a header that hides on scroll down and shows on scroll up, but not with a simple trigger that goes from 0 to 100 on a threshold, but instead I want it to be bound to the scroll. Example: http://oma.eu/
Any ideas?
You can easily do that with Headroom.js: https://wicky.nillia.ms/headroom.js/
You cannot do that in pure javascript without checking the pageYOffset of the window, there is a simple example on w3schools website, see the demo here:
How To Hide Navbar on Scroll Down
UPDATED:
below is a demo of the updated fix (using css transform translateY to set the position of the header):

I am using the following calendar with Django:
https://xdsoft.net/jqplugins/datetimepicker/
Problem is that when scrolling down the page, Month and Year calendar
components goes over my menu-bar. There is a way to fix this ? maybe
to override some css from the calendar or in my HTML/Javascript ?
I reproduced my scenario within an HTML example from w3school. See code snipped.
No need to be set such a high z-index value for inline calendar since
is not showing up over the date field like the default calendar.
Instead of z-index: 9999 use z-index: 101 like the dropdowns for
month and year uses. Solution is to override calendar's css:
<script>
.xdsoft_datetimepicker .xdsoft_label {
z-index: 101 !important;
}
</script>
I have a single page. I have min four sections on my page. I have to add the active class to the li tag on the menu when scrolling at the bottom with the respective section. For example, If about us section is on the screen then add class active to the li tag. If the gallery section is on the screen then add active class and remove the active class from the previous li.
I have to change the color and adding the bottom border to the active menu list. I don't want to use any plugin.
This is an example. It's adding the class active and changing the color of nav list

hi follow up the below snippet what I do here is made an one function called activateLink and I gave ID to links and clicking the link I add an active class to that particular li with the help of jquery
$(function() {
$('.smothscrollclass a[href*="#"]:not([href="#"])').click(function() {
if (location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '') && location.hostname == this.hostname) {

target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
if (target.length) {
$('html, body').animate({
scrollTop: target.offset().top - 100
}, 1000);
return false;
}
}
});
});
function activateLink (link,section) {
if(section){
$('html, body').animate({
'scrollTop' : $("#"+section).position().top
},function(){
$( ".active" ).removeClass( "active" )
$("#"+link).addClass("active");
});
}else{
$( ".active" ).removeClass( "active" )
$("#"+link).addClass("active")
}
}
function checkSectionExistance (sectionId,linkId) {
var element = document.querySelector('#'+sectionId);
var position = element.getBoundingClientRect();
// checking for partial visibility
if(position.top < window.innerHeight && position.bottom >= 0) {
$( ".active" ).removeClass( "active" )
$("#"+linkId).addClass("active")
}
}
window.addEventListener('scroll', function() {

let me know if it's helpful
with pure js you need to use document.body.scrollTop; to define how much was scrolled then remove style active from all li-s and add to the current or just manually for each remove the previous for(let i = 0;i<liClass.length;i++){liClass[i].classList.remove("active")} then add to the current targetting it by ID or unique class, works fine for me for jQuery is the same just $("body").scrollTop()
I upgraded a bit now everything is crystal clear ;)
For scrolls I used pure html just add ID to the element where you want to scroll and add <a href="#theIdOfElement">
the classes I did with jQuery as you asked
2nd EDIT:
let x=0;
$(document).ready(()=>{
$("a").click((e)=>{
//Removes class active from all a-s and all divs
$("a").removeClass("active");
$("div").removeClass("active");
//Adds only to clicked one
$(e.target).addClass("active");
//Adds class active to divs that contain the text on which you clicked
$("div:contains("+ $(e.target).text() +")").addClass("active");
});
$(document).scroll(()=>{
$("p").text( $(document).scrollTop());
if($(document).scrollTop() >= 970){
//If you want to get style permenent remove line below
$("div").removeClass("active");
$("#contacts").addClass("active");
}
else if($(document).scrollTop() >= 508){
//If you want to get style permenent remove line below
$("div").removeClass("active");
$("#about").addClass("active");
}
else if($(document).scrollTop() >= 8){
//If you want to get style permenent remove line below
$("div").removeClass("active");
$("#home").addClass("active");
}
});
})

I want to turn on the div #overlay opacity: 1 when I move mouse over div #header. Also it's important that #header remains relative, so it won't affect that.
I tried to do this with jQuery (code below), but it did not work at all.

});
});

This is how I want the header to look like if I move mouse over it:
Neither the JSFiddle and nor the code you included in your question will work, but they don't work for different reasons. The JSFiddle doesn't work because you haven't included the jQuery library. But otherwise, it should work. But let's focus on the code you provided. Let's look at your code with the less relevant portions omitted.

$("#header", ...) runs before the content in the body is created in the DOM, so the hover event listener can't attach to anything. You can fix this by wrapping it all in a $(document).ready() call, as shown below. This waits for the body to be created in the DOM before attaching the hover event listener. You can read more at the jQuery docs site.
$(document).ready(function() {
$("#header").hover(
function() {
$("#overlay").fadeTo(200, 1);
},
function() {
$("#overlay").fadeTo(200, 0, function() {
$(this).hide();
});
}
);
});
I am trying to create a navigation bar that sticks to the top of the screen after some scrolling. I followed two different tutorials but I can't seem to make either of them work properly.
The first tutorial does not stick to the top of the screen at all. The second tutorial does stick to the top of the screen, but if you scroll down far enough, you can't see the navigation until after it sticks to the top.
This is what I have right now (following the first tutorial):
var n = $("#nav-bar");
ns = "nav-bar-scrolled";
hdr = $('#nav-bar').offset().top;
$(window).scroll(function(){
if($(this).scrollTop() > hdr){
n.addClass(ns);
}else{
n.removeClass(ns);
}
});
This is the JS code following the second tutorial:
$(function(){
// Check the initial Poistion of the Sticky Header
var stickyHeaderTop = $('header').height();
$(window).scroll(function(){
if( $(window).scrollTop() > stickyHeaderTop ) {
$('#nav-bar').css({position: 'fixed', top: '0px'});
$('#stickyalias').css('display', 'block'); //this doesn't do anything
} else {
$('#nav-bar').css({position: 'static', top: '0px'});
$('#stickyalias').css('display', 'none'); //this doesn't do anything
}
});
});
Full code here: https://jsfiddle.net/linahsie/rhp65j2b/2/
Thank you!
In your JS, n should be #nav-bar, ns (since you're toggling a class) should be nav-bar-scrolled, and hdr should be the bottom position of the header, since that's the point where you want the nav to affix itself to the top of the window. Then in your CSS, you want to use #nav-bar.nav-bar-scrolled as the selector for the fixed menu to match the changes you're making in your JS.
var n = $("#nav-bar");
ns = "nav-bar-scrolled";
hdr = $('header').offset().top + $('header').outerHeight();
$(window).scroll(function(){
if($(this).scrollTop() > hdr){
n.addClass(ns);
}else{
n.removeClass(ns);
}
});

Had a look at the jquery, you define var n = $("#nav"); but you don't have a nav with id="nav", change to n = $("#nav-bar");
I have 3 rollover image that i want to use it as a trigger to show text box under each images. Whenever I try to click it disappears and does not works. I'm trying to make the first one work at least.
here's my code and webpage.
http://yunjinkimdesign.com/question/practice_div.html?
the image showed on snippet is just sample I brought from google...snippet and my actual sample is different
$('.top').on('click', function() {
$parent_box = $(this).closest('.box');
$parent_box.siblings().find('.bottom').hide();
$parent_box.find('.bottom').toggle();
});
img{
width: 200px;
border-radius: 50%;
}
div{
margin: 20px;
}
.container .box .top {
padding: 12px;}
.container .box .bottom {
padding: 12px;
background-color: red;
color: white;
display: none;

You have given href=? in the anchor, Just replace the ? to # or remove href attribute from anchor and your code will run as you want.
