I’m looking for help on a project I’m working on and I can’t seem to figure it out. I’ve searched and tried various scripts as well as no conflict scripts. I’m hoping someone can help me out.
I have a single page that anchors from the nav to content on the page. When you hover over an image in the middle of the page, you can click to an off canvas page. I’ve got this working, however I would like to have smooth scrolling when you click on the main navigation at the bottom of the page. It seems that the off canvas anchors and the smooth scrolling script don’t work together. I’m very new to jquery and javascript, so I can’t seem to make it work.
I found this code for the smooth scrolling (right now I have this commented out), but when i place this code on the page, it breaks the nav anchors:
$(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;
}
}
});
});
Is there another code that can work on my page? You can inspect my page here:
http://ebresearch1.wpengine.com/index.html
Also, I’m having trouble with having my nav icons have an active state on them.
I’m using this code:
jQuery('.nodes a').click(function () {
jQuery(this).find('.inactive-circle').toggleClass('active hide');
});
But it only toggles the active and non active states. I want them to stay active only until you click on another nav item.
Tablet problem:
On another note, my mobile/tablet hamburger links in nav don’t close nav after clicked. It just stays open. I can’t seem to trigger the off canvas to close after clicking on a link.
I know this is a lot of information, but I’m stuck. If I need to provide more information, please let me know and i’ll post it.
Thanks!
quick one for your second problem:
jQuery('.nodes a').click(function () {
jQuery('.nodes a').find('.inactive-circle').removeClass('active hide');
jQuery(this).find('.inactive-circle').addClass('active hide');
});
not quite sure how your divs and css are set up here as it feels like it could be simpler somehow, but the main principle with this is to first make all of your .nodes a divs inactive and then make this one active.
for third problem, this is a bit of a hack but to avoid meddling with your offCanvas script you can trigger a click on the hamburger when a menu div is clicked:
jQuery('#0 a').click(function () {
jQuery('#rightBurger').trigger('click');
});
hope that helps, gotta run but will come back come back and attempt the main one if no one else does.

I am trying to make some collapsible accordion containers on my website accessible, but I am running into an issue.
The accordions are controlled by link elements on the page - this way, a keyboard-only user can tab to them and access them. The first issue I ran into was that if a user tabbed to one of the links, the page wouldn't always scroll up to show them which one they had tabbed to. I fixed this issue setting the focus using the following code, which scrolls the link to the top of the viewport:
$(".accordion .accordion-item .accordion-heading a").focus(
function()
{
$('html:not(:animated), body:not(:animated)').animate({
scrollTop: $(this).offset().top
}, 250);
}
);
The problem I am encountering now is that when a mouse-user clicks on the link, it jumps to the top of the page and does not open the container unless the mouse-user clicks the link again.
Is there a way I can set the focus code above to only fire if the link has been tabbed to? Or, is there a better way of handling the focus issue so that it works for both keyboard-only and mouse users?
Thanks!
Firstly a quick apology, having now seen your accordion is built correctly, links with in-page anchors are actually preferable if the accordion is constructed using javascript on page load and falls back to just a list of in page anchor links and content between them.
I am that used to seeing <a href="#"> on accordion openers and weird accordion implementations I jumped to conclusions, change it back from <buttons>!
Fixing your problem
Probably not the answer you are looking for but remove the .focus() function entirely.
It produces strange behaviour where if I have one accordion item open and i tab back with Alt + Tab quickly scrolling can be really confusing as it jumps around if you tab quicker than the scroll.
One of the golden rules of accessibility is to only adjusted the scroll position on a page if it is expected (i.e. a return to top button or using in-page anchors).
In the example and on your website once I disabled the 'scroll to top on focus' the site actually behaved as expected.
I understand why you did it as occasionally a link that is focused appears off the page, however this remedies itself when you tab again or by scrolling down (your site is logical so that if I tab and my focus is not visible I know it is off the page.)
This tends to happen (items not scrolling into view) when the item is just out of sight, by a px or two, it is common and ironically now falls into 'expected' behaviour (another rule, follow accepted and expected behaviour when designing components and pages).
If you really want to fix it
In your focus function instead of just scrolling to the top of the page whenever an item is focused, check if it is off the page.
Below is an example function I found (not tested) that you can use to check if the item is in the viewport, if it is then don't do anything, if it isn't then do your scroll function.
var isInViewport = function (elem) {
var bounding = elem.getBoundingClientRect();
return (
bounding.top >= 0 &&
bounding.left >= 0 &&
bounding.bottom <= (window.innerHeight || document.documentElement.clientHeight) &&
bounding.right <= (window.innerWidth || document.documentElement.clientWidth)
);
};
So roughly (yet again haven't tested that the correct items are passed in, this is just to give you an idea).
$(".accordion .accordion-item .accordion-heading a").focus(
function()
{
if(isInViewport(this) === false){
//item is not in the viewport so scroll it into view
$('html:not(:animated), body:not(:animated)').animate({
scrollTop: $(this).offset().top //I would perhaps add a couple of hundred pixels here to make the item appear in a more natural area.
}, 250); //remove the animation as a further accessibility improvement, animations can be off putting to people with motion or anxiety disorders.
}
}
);
This fixes your problem as no mouse user will ever be able to click an item that is off the page so they won't ever trigger the scroll event that causes the focus issue.
You can change the event setting: Instead focus() event you will do a click() event: When you click a link, you'll scroll up. This will solve the problem of both keyboard navigation and mouse clicking;And this is also more true in terms of accessibility.
$(".accordion .accordion-item .accordion-heading a").click(
function(e)
{
e.preventDefault();
$('html:not(:animated), body:not(:animated)').animate({
scrollTop: $(this).offset().top
}, 250);
}
);
Don't forget to change the link setting to a button by adding role=button attribute.
and add aria-expanded attribute.
I'm trying to create some sort of info "Scroll Down" button (not clickable) which has to be visible while scroll bar is up on top, fade out when scroll down a few pixels and fade back in when up again.
So far I was able to create the arrow and the message so far as well as the fading part.
Here is a fiddle: https://jsfiddle.net/8b3jL7r0/1/
var btn = $("#button");
$(window).scroll(function() {
if ($(window).scrollTop() < 100) {
btn.addClass("show");
} else {
btn.removeClass("show");
}
});
var btn2 = $("#scrolltxt");
$(window).scroll(function() {
if ($(window).scrollTop() < 100) {
btn2.addClass("showx");
} else {
btn2.removeClass("showx");
}
});
The problem with is that the arrow and the info text 'Scroll Down' does not appear right from the beginning, you have to scroll down a bit so they appear on top and then everything works smooth. Any clue how to make them visible right from the first load of the code?
Any idea how could I transfer all this code into one single code module in WordPress and have it work exactly like in the fiddle ? Because I've tried to insert it but it seems to not work at all, nothing appears on the page, not the arrow nor the info text.
I just added the inital classes to both elements:
https://jsfiddle.net/4e2cafju/
<div id="button" class="show"></div>
<div id="scrolltxt" class="showx">scroll down</div>
for 2:
You should be able to put these elements directly into a template. You should be able to add the css to the style sheet. And you could lnk to an external JS file. That would probably be best practice. You could also put all the code into a single page. I'm not sure how your wordpress install / theme is set up.
I looked through this website for similar question, but couldn't find any.
So I've been working on a website with bootstrap3 for a little bit now and most of the formatting/design part is done, but have one problem I can't solve myself.
I added Jquery to make the navbar shrinks and changes background color when users scroll down to a certain point.(Thanks to peeps helped me out here)
It kind of works, but the movement of it is really weird.
When load the page, the navbar is already shrunk and background is colored, but when scrolled a little bit it blows up in size and the background disappears, and when scrolled even more to the point where I set Jquery to start working, navbar shrinks back and background color changes again.
It's hard to explain in writing, so please see the website and see what I'm talking about.
Below is the website I'm working on.
Test website
I'm assuming its the Jquery not working when loaded, so the CSS setting supposed to be hidden(shorter navbar height and background color) isn't hidden initially.
Below is the jquery code:
$(document).ready(function(){
$(window).scroll(function () {
if ($(window).scrollTop() > 70) {
$("#top-bar").addClass('animated-header');
} else {
$("#top-bar").removeClass('animated-header'); }
});
$("#clients-logo").owlCarousel({
itemsCustom : false,
pagination : false,
items : 5,
autoplay: true,
})
});
Thanks for the help in advance!
Nice website!
Take a look at your header element, you will see that you already put the animated-header class there which causes the problem. Here is your code:
<header id="top-bar" class="navbar-fixed-top animated-header">
What you can do is simply remove that class, and your script above will help deal with adding/removing this class base on the scrollTop value. Something like this will help:
<header id="top-bar" class="navbar-fixed-top"> <!-- without animated-header -->
We are setting our scroll position back to zero, so this works fine. Add this,
$(document).ready(function () {
$('html,body').animate({
scrollTop : 0
},10);
});
$(document).ready(function () {
$(window).scroll(function(){
if($(window).scrollTop() >= 70){
$("#top-bar").addClass("animated-header");
}
if($(window).scrollTop() <= 70){
$("#top-bar").removeClass("animated-header");
}
});
});
I have been working on this website since last week. It is a school project, and I can't figure out why part of it isn't working. When I scroll down, click on the menu button, leave the menu down, then scroll back up, the navbar keeps its height even though I take away the class that resized it. I have attempted to use Google Chrome's developer tools to see what is happening. It just shows the height property crossed out. I have no idea why it won't work, and I have looked for any reason in my code. I also tried it in Internet Explorer to see if chrome was just having problems with it for some reason. It did the same thing there causing me to assume the problem is in my code.

got problem!!
After scrolling back to top you didn't change height of nav element;after scroll back make it 40px again it may solve your problem.
if (flag !== 2 && $(window).scrollTop() === 0) {
//add this line
$nav.css({height:'40px'});
$nav.slideUp();
$nav.removeClass("dropDown");
$menu.stop(true,false).slideUp(800, function () {
$heading.css({'margin-left':'40px'})
});
$nav.stop(true,false).slideDown();
flag = 2;
}
I'm really stuck with this one and have no idea how to solve this, I use jQuery ~ usually without too many problems. But as I don't write JS I do get stuck :(
I've searched and searched for answers and tried out too many approaches and not getting anywhere... :( I bet I'm missing something very obvious or simple, hoping someone might be able to help...
ok - the problem:
I have a website for my webdesign course which shows the main nav in the left column. For the smallest screens (ie below 420px width) - I want to hide the menu, displaying a 'view menu' link instead which uses the jQuery toggle() function to show / hide the menu on demand.
Initially, I did this via a straight forward toggle alone - all fine - apart from the issue that the menu would remain hidden once it was shown and hidden once on a small screen. If the window is resized - it would remain hidden.
That was the problem I set out to solve, mentioning it here as I might be going down the wrong path entirely here ~ doubting whether I'm doing this in the right way :'(
Now - I am using JS to hide the 'view menu' link for all screens, only showing on screens smaller than 420px. I've added the resize() function as well to allow more dynamic behaviour.
Everything is working as intended for the showing and hiding of my menu - BUT....
The toggle link itself is set to display:block - when the window loads below 420px, it displays as intended: set to block (spanning full width for a nicely solid active link) with the text centred.
However, when I load the page at larger window size, then resize to below 420px width - the toggle link seems to become inline? Not at full width any longer, text appears to be left aligned as the element no longer is full width...?!
I've tried setting width in CSS, tried resetting with via resize() element, via assigning 100% width via JS....nothing is working - I'm sure I'm missing something....
I'd really appreciate any pointers or thoughts ~ feel like I'm missing something very basic here....
the website: webeyedea.info
here's my JS code, following the link to jQuery:
// check for window size size on page load and show relevant content only
$(function() {
if ($(window).width() > 420) {
$('#toggle-nav').hide();
$('nav ul').show();
}
else {
$('#toggle-nav').show();
$('nav ul').hide();
}
});
// check for window resize - show nav again for larger screens after hiding
$(window).resize(function() {
if ($(window).width() > 420) {
$('#toggle-nav').hide();
$('nav ul').show();
}
else {
$('#toggle-nav').show();
$('nav ul').hide();
}
});
// show menu (smallest screens)
$('nav #toggle-nav').click(function() {
$('nav ul').slideToggle('slow', function() {
// Animation complete.
});
$('ul').addClass('view');
});
UPDATE: SEE JSFIDDLE
When you call .show() on an element it sets the display property to the previous value and if it does not exist I believe it takes the default browser value which may be inline in your case. Try setting it explicitly to block.
I'm not sure what is doing what here since I don't have a mobile to test it, but could you try to replace your hide/show with a css function that toggle between display:none and display:block ?
Like this :
$('#toggle-nav').css('display','none');
$('#toggle-nav').css('display','block');
ALMOST ! NOT SOLVED
one solution, thanks to Vlad Radulescu (on Forrst) ~ via this jsfiddle fork
$('a#toggle-nav').css('display','none');
// Show the menu if Window width is less than 420
$(window).resize(function() {
if ( $(window).width() > 420 ) {
$('#toggle-nav').css('display','none');
$('nav ul').show();
}
else {
$('#toggle-nav').css('display','block');
$('nav ul').hide();
}
});
// Slide the Menu on smaller screens
$('nav #toggle-nav').click(function() {
$('nav ul').slideToggle('slow');
});

I tested this on the iphone simulator and it works. My test was I copied the codes to a local file and tested. I put all the js inside of document.ready
make sure you have the meta in the header
<meta name = "viewport" content = "width=device-width, initial-scale=1.0">
