Go to anchor without changing url - javascript

On loading a page I would like it to go to #content without changing the url.
I thought I would be able to use
window.location.hash = "content";
window.location.replace("#content", "");
but #content still exists on the url.
Any better method?
Edit:
Also tried
window.location.hash = "content";
window.location.replace(window.location.toString().replace("#content", ""));
But this sends the browser into a loop.

You could find the vertical position of the anchor with that id, and then scroll to that position.

Go to or Scroll to anchor specified div id without changing url
TRY DEMO
function scrollSmoothTo(elementId) {
var element = document.getElementById(elementId);
element.scrollIntoView({
block: 'start',
behavior: 'smooth'
});
}
#userdiv {
margin-top: 200px;
width: 200px;
height: 400px;
border: 1px solid red;
}
a {
color: #337ab7;
cursor: pointer;
}
a:hover {
text-decoration: underline;
}
<a onclick="scrollSmoothTo('userdiv')">
Scroll to userdiv
</a>
<div id="userdiv">
Lorem ipsum this is a random text
</div>

This is a 10 year old question but I came across this issue when using Nextjs and wanted to smoothly navigate to a lower element without effecting the url... Nextjs, Typescript.
const Anchor: React.FC = () => {
const smoothScrollTo = e => {
e.preventDefault();
const element = document.getElementById('search');
element.scrollIntoView({
block: 'start',
behavior: 'smooth' // smooth scroll
})
};
return (
<div>
<a
href=""
onClick={smoothScrollTo}>
Let's go!
</a>
<div id = "search">Take me here!</div>
</div>
)
};
Now, it would probably be a best practice to be using refs here but this did exactly what I needed! I'm sure other improvements can be made too!

This will do it with a nice animation:
Click to scroll
<div id="link" style="margin-top: 1000px; height: 300px; background-color: blue; margin-bottom: 1000px">
Click and scroll to this div without changing url!
</div>
<script>
$('a').on('click', function(e) {
// prevent default anchor click behavior
e.preventDefault();
// store hash
var hash = this.hash;
if ($(hash).length) {
$('html, body').animate({
scrollTop: $(hash).offset().top
}, 300, function() {
// Do something fun if you want!
});
}
});
</script>

Skip to Content using created elements with jQuery

I'm working within an in house platform, so the only way I can create elements for skip navigation is by using jQuery. I have no trouble creating the link as well as the target div (just after the header). I've add JS to get around the event delegation issue with the created link, but while the click event is firing (tested with a log) it still doesn't skip down to the newly created element #skipTarget. Also our sites use a base url, which is why the link is just '#skipTarget'. What am I doing wrong?
Here is my snippet of my JS:
$(document).ready(function() {
const skipNav = $('<a id="skip-nav" alt="Skip to Content">');
const skipSearch = $('<a id="skip-search" alt="Skip to Inventory">');
let contentLink = window.location.pathname;
if (contentLink == '/') {
contentLink = '';
}
const skipTarget = $('<div id="#skipTarget" tabindex="-1">');
$('body > header').after(skipTarget);
skipNav.text('Skip to Main Content');
skipNav.attr('href', contentLink + '#skipTarget');
$('body > header').prepend(skipNav);
skipSearch.text('Skip to Inventory');
skipSearch.attr('href', contentLink + '#inventory-listing');
$('aside#refine-search').prepend(skipSearch);
$('header').on('click', '#skip-nav', function(event) {
console.log('test:', event);
console.log('contentLink: ', contentLink);
});
});
#skip-nav,
#skip-search {
z-index: -999;
position: absolute;
color: transparent;
padding: 3px;
}
#skip-nav:active,
#skip-nav:focus,
#skip-search:active,
#skip-search:focus {
z-index: 999;
background: black;
color: white;
}
<body>
<header>
<a id="skip-nav" href="#skipTarget">Skip to Main Content</a>
<div>header content and menus to skip</div>
</header>
<div id="#skipTarget" tabindex="-1"></div>
</body>
Thanks for any help
I can't believe I missed it, but it was just a typo. When defining skipTarget, I set it to id=#skipTarget, rather than id=skipTarget. Thanks all for looking at it.

Smooth scroll to id except when user is already at that location

I'm running the following script when a user clicks on a button, to scroll to a specific div on the page, along with a few other unrelated functions.
The problem is that the button itself is supposed to always remains in view, and thus can be spam-clicked to cause the page to 'lag' while it's busy moving over and over to the same location. I would like to counter this behavior by only executing the scroll when the page is not already at that specific location.
Unfortunately I have no real experience working with JavaScript/jQuery and have not been able to find an example of something like this being used.
Here's my sample code:
HTML
<div id="navButton">Button</div>
<div id="listContent">Content that must be visible after button click goes here</div>
Script
window.onload=function(){
document.getElementById("navButton").onclick = function(){
$("html, body").animate({scrollTop: $("#listContent").offset().top -165}, 400);
}
}
Maybe this Example could help you... Change the hash first then listen to the hashchange Event. When you reload the page it will scroll down to your anchor.
$(document).ready(function() {
// check for hash when page has loaded
if (getHash() != null) {
checkForScrolling();
}
});
// check for hash when hash has changed
window.onhashchange = function() {
checkForScrolling();
};
// return hash if so or null if hash is empty
function getHash() {
var hash = window.location.hash.replace('#', '');
if (hash != '') {
return hash;
} else {
return null;
}
}
// this function handles your scrolling
function checkForScrolling() {
// first get your element by attribute selector
var elem = $('[data-anchor="' + getHash() + '"]');
// cheeck if element exists
if (elem.length > 0) {
$('html, body').stop().animate({
scrollTop: elem.offset().top
}, 300);
}
}
body {
font-family: Helvetica
}
section {
position: relative;
margin-bottom: 10px;
padding: 20px;
height: 300px;
background-color: #eee;
}
section a {
display: block;
position: absolute;
bottom: 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
<h1 data-anchor="start">Smooth Scrolling</h1>
<ul>
<li>Scroll to Anchor 1
</li>
<li>Scroll to Anchor 2
</li>
<li>Scroll to Anchor 3
</li>
</ul>
<section>
<h2 data-anchor="1">First Anchor</h2>
Back to top
</section>
<section>
<h2 data-anchor="2">Second Anchor</h2>
Back to top
</section>
<section>
<h2 data-anchor="3">Third Anchor</h2>
Back to top
</section>
</div>
Try this if worked
<div id="navButton" onclick="moveElement('listContent');">Button</div>
<div id="listContent">Content that must be visible after button click goes here</div>
You will need jquery included for this script code
function moveElement(divId) {
$('html, body').animate({
scrollTop: $("#"+divId).offset().top
}, 2000);
}
And if you see it not working then try by adding below css. It will make gap between button and your div.
#navButton {
height: 300px;
border:1px solid green;
}
#listContent {
height: 900px;
border: 1px solid red;
}

Prevent children divs from moving while div toggle

I'm new and have I think very simple problem to solve.
I have 4 buttons to show/hide each panel. What should I do to prevent child divs from moving to te left while hiding some div?
I prefer them to stay at the initial position.
This is my code:
HTML:
<button class="panel-button" data-panel="panel1">1</button>
<button class="panel-button" data-panel="panel2">2</button>
<button class="panel-button" data-panel="panel3">3</button>
<button class="panel-button" data-panel="panel4">4</button>
<div class="wrapper">
<div id="panel1">1</div>
<div id="panel2">2</div>
<div id="panel3">3</div>
<div id="panel4">4</div>
</div>
JS:
$(function() {
$('.panel-button').on('click',function(){
var panelId = $(this).data('panel');// attr('data-panel')
$('#'+panelId).toggle();
});
});
CSS:
.wrapper {
overflow: hidden;
width: 420px;
}
.wrapper > div {
width: 100px;
height: 100px;
background: green;
float: left;
margin-left: 5px;
margin-top: 10px
}
Apply css rule opacity = 0; to the div, instead of hiding it.
Like this:
$('.panel-button').on('click',function(){
var pnl = $('#' + $(this).data('panel'));
pnl.css('opacity', pnl.css('opacity') == '0' ? '1' : '0');
});
Solution for clickability issue:
$('.panel-button').on('click',function(){
var pnl = $('#' + $(this).data('panel'));
if(pnl.is(':visible'))
$('<div></div>').appendTo(pnl).width(pnl.width());
else
pnl.next().remove();
pnl.toggle();
});
But still you can use another approach
You can use the visibility property in CSS to achieve this as shown in the below Fiddle link : link
JS Snippet:
$(function() {
$('.panel-button').on('click',function(){
var panelId = $(this).data('panel');// attr('data-panel')
console.log($('#'+panelId).css('visibility'));
if($('#'+panelId).css('visibility') === 'hidden') {
$('#'+panelId).css('visibility','visible');
}
else {
$('#'+panelId).css('visibility','hidden');
}
});
});
The CSS visibility is designed to keep the space a DOM object occupies, but not actually rendering it. Opacity changes its appearance, but not its behavior (eg. still clickable).
So instead of .toggle(), combine visibility with jQuery's .toggleClass():
jsFiddle solution
$(function() {
$('.panel-button').on('click',function(){
var panelId = $(this).data('panel');// attr('data-panel')
$('#'+panelId).toggleClass('hideMe');
});
});

Selecting child of previous parent jQuery

Lately I've been trying my hand at animation using CSS and jQuery, it went well, however, now I want to do a bit more.
That is, once the user clicks information should show up on top of the image.
At the moment, I just have a few tags on which I perform the animations and class toggles.
My question is, I've thought about doing the following:
<div class= "singleImage">
<img src.... class="actualImage">
<p>text to put over the image</p>
</div>
This would be done per image which means that I'll have about 5 of them with different images.
However, I don't know how to go about selecting the previous element of class "actualImage".
Has anyone got any suggestions?
Thank you
Use the jQuery prev function. Example: Assume you want to select the image previous to the second image:
var foo = $(".singleImage").eq(1);
var bar = $(foo).prev().find('.actualImage');
Fiddle
Try this:
$('singleImage').children('.actualImage').prev();
I'm not sure why you are trying to select the previous element, but you could do something akin to this:
Bind a function to the click event for the element containing your image and caption.
Inside this function, toggle the caption.
Also, bind a click event handler to the body to detect clicks "off" the containing element.
HTML:
<a href="#" class="has-caption">
<img src="http://placehold.it/300x300" />
<span class="caption">This is a caption</span>
</a>
CSS:
a.has-caption { position: relative; }
a.has-caption .caption {
background: rgba(0, 0, 0, .25);
bottom: 0;
color: #fff;
display: none;
height: 20px;
left: 0;
line-height: 20px;
position: absolute;
width: 100%;
}
a.has-caption img { vertical-align: bottom }
JavaScript
$('a.has-caption').on('click', function(e) {
e.preventDefault(); e.stopPropagation();
var self = $(this)
, tmpId = 'toggle-' + Date.now();
self.addClass(tmpId);
$('span.caption', self).toggle();
$('body').one('click', function(e) {
if (!$(event.target).closest('.' + tmpId).length) {
$('span.caption', '.' + tmpId).hide();
self.removeClass(tmpId);
};
});
});

offsetting an html anchor to adjust for fixed header [duplicate]

This question already has answers here:
Fixed page header overlaps in-page anchors
(38 answers)
Closed 7 years ago.
I am trying to clean up the way my anchors work. I have a header that is fixed to the top of the page, so when you link to an anchor elsewhere in the page, the page jumps so the anchor is at the top of the page, leaving the content behind the fixed header (I hope that makes sense). I need a way to offset the anchor by the 25px from the height of the header. I would prefer HTML or CSS, but Javascript would be acceptable as well.
You could just use CSS without any javascript.
Give your anchor a class:
<a class="anchor" id="top"></a>
You can then position the anchor an offset higher or lower than where it actually appears on the page, by making it a block element and relatively positioning it. -250px will position the anchor up 250px
a.anchor {
display: block;
position: relative;
top: -250px;
visibility: hidden;
}
I found this solution:
<a name="myanchor">
<h1 style="padding-top: 40px; margin-top: -40px;">My anchor</h1>
</a>
This doesn't create any gap in the content and anchor links works really nice.
I was looking for a solution to this as well. In my case, it was pretty easy.
I have a list menu with all the links:
<ul>
<li>one</li>
<li>two</li>
<li>three</li>
<li>four</li>
</ul>
And below that the headings where it should go to.
<h3>one</h3>
<p>text here</p>
<h3>two</h3>
<p>text here</p>
<h3>three</h3>
<p>text here</p>
<h3>four</h3>
<p>text here</p>
Now because I have a fixed menu at the top of my page I can't just make it go to my tag because that would be behind the menu.
Instead, I put a span tag inside my tag with the proper id.
<h3><span id="one"></span>one</h3>
Now use 2 lines of CSS to position them properly.
h3{ position:relative; }
h3 span{ position:absolute; top:-200px;}
Change the top value to match the height of your fixed header (or more).
Now I assume this would work with other elements as well.
FWIW this worked for me:
[id]::before {
content: '';
display: block;
height: 75px;
margin-top: -75px;
visibility: hidden;
}
As this is a concern of presentation, a pure CSS solution would be ideal. However, this question was posed in 2012, and although relative positioning / negative margin solutions have been suggested, these approaches seem rather hacky, create potential flow issues, and cannot respond dynamically to changes in the DOM / viewport.
With that in mind I believe that using JavaScript is still (February 2017) the best approach. Below is a vanilla-JS solution which will respond both to anchor clicks and resolve the page hash on load (See JSFiddle). Modify the .getFixedOffset() method if dynamic calculations are required. If you're using jQuery, here's a modified solution with better event delegation and smooth scrolling.
(function(document, history, location) {
var HISTORY_SUPPORT = !!(history && history.pushState);
var anchorScrolls = {
ANCHOR_REGEX: /^#[^ ]+$/,
OFFSET_HEIGHT_PX: 50,
/**
* Establish events, and fix initial scroll position if a hash is provided.
*/
init: function() {
this.scrollToCurrent();
window.addEventListener('hashchange', this.scrollToCurrent.bind(this));
document.body.addEventListener('click', this.delegateAnchors.bind(this));
},
/**
* Return the offset amount to deduct from the normal scroll position.
* Modify as appropriate to allow for dynamic calculations
*/
getFixedOffset: function() {
return this.OFFSET_HEIGHT_PX;
},
/**
* If the provided href is an anchor which resolves to an element on the
* page, scroll to it.
* #param {String} href
* #return {Boolean} - Was the href an anchor.
*/
scrollIfAnchor: function(href, pushToHistory) {
var match, rect, anchorOffset;
if(!this.ANCHOR_REGEX.test(href)) {
return false;
}
match = document.getElementById(href.slice(1));
if(match) {
rect = match.getBoundingClientRect();
anchorOffset = window.pageYOffset + rect.top - this.getFixedOffset();
window.scrollTo(window.pageXOffset, anchorOffset);
// Add the state to history as-per normal anchor links
if(HISTORY_SUPPORT && pushToHistory) {
history.pushState({}, document.title, location.pathname + href);
}
}
return !!match;
},
/**
* Attempt to scroll to the current location's hash.
*/
scrollToCurrent: function() {
this.scrollIfAnchor(window.location.hash);
},
/**
* If the click event's target was an anchor, fix the scroll position.
*/
delegateAnchors: function(e) {
var elem = e.target;
if(
elem.nodeName === 'A' &&
this.scrollIfAnchor(elem.getAttribute('href'), true)
) {
e.preventDefault();
}
}
};
window.addEventListener(
'DOMContentLoaded', anchorScrolls.init.bind(anchorScrolls)
);
})(window.document, window.history, window.location);
Pure css solution inspired by Alexander Savin:
a[name] {
padding-top: 40px;
margin-top: -40px;
display: inline-block; /* required for webkit browsers */
}
Optionally you may want to add the following if the target is still off the screen:
vertical-align: top;
My solution combines the target and before selectors for our CMS. Other techniques don't account for text in the anchor. Adjust the height and the negative margin to the offset you need...
:target::before {
content: '';
display: block;
height: 180px;
margin-top: -180px;
}
This takes many elements from previous answers and combines into a tiny (194 bytes minified) anonymous jQuery function. Adjust fixedElementHeight for the height of your menu or blocking element.
(function($, window) {
var adjustAnchor = function() {
var $anchor = $(':target'),
fixedElementHeight = 100;
if ($anchor.length > 0) {
$('html, body')
.stop()
.animate({
scrollTop: $anchor.offset().top - fixedElementHeight
}, 200);
}
};
$(window).on('hashchange load', function() {
adjustAnchor();
});
})(jQuery, window);
If you don't like the animation, replace
$('html, body')
.stop()
.animate({
scrollTop: $anchor.offset().top - fixedElementHeight
}, 200);
with:
window.scrollTo(0, $anchor.offset().top - fixedElementHeight);
Uglified version:
!function(o,n){var t=function(){var n=o(":target"),t=100;n.length>0&&o("html, body").stop().animate({scrollTop:n.offset().top-t},200)};o(n).on("hashchange load",function(){t()})}(jQuery,window);
For modern browsers, just add the CSS3 :target selector to the page. This will apply to all the anchors automatically.
:target {
display: block;
position: relative;
top: -100px;
visibility: hidden;
}
You can do it without js and without altering html. It´s css-only.
a[id]::before {
content: '';
display: block;
height: 50px;
margin: -30px 0 0;
}
That will append a pseudo-element before every a-tag with an id. Adjust values to match the height of your header.
I had been facing a similar issue, unfortunately after implementing all the solutions above, I came to the following conclusion.
My inner elements had a fragile CSS structure and implementing a position relative / absolute play, was completely breaking the page design.
CSS is not my strong suit.
I wrote this simple scrolling js, that accounts for the offset caused due to the header and relocated the div about 125 pixels below. Please use it as you see fit.
The HTML
<div id="#anchor"></div> <!-- #anchor here is the anchor tag which is on your URL -->
The JavaScript
$(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) {
$('html,body').animate({
scrollTop: target.offset().top - 125 //offsets for fixed header
}, 1000);
return false;
}
}
});
//Executed on page load with URL containing an anchor tag.
if($(location.href.split("#")[1])) {
var target = $('#'+location.href.split("#")[1]);
if (target.length) {
$('html,body').animate({
scrollTop: target.offset().top - 125 //offset height of header here too.
}, 1000);
return false;
}
}
});
See a live implementation here.
For the same issue, I used an easy solution : put a padding-top of 40px on each anchor.
As #moeffju suggests, this can be achieved with CSS. The issue I ran into (which I'm surprised I haven't seen discussed) is the trick of overlapping previous elements with padding or a transparent border prevents hover and click actions at the bottom of those sections because the following one comes higher in the z-order.
The best fix I found was to place section content in a div that is at z-index: 1:
// Apply to elements that serve as anchors
.offset-anchor {
border-top: 75px solid transparent;
margin: -75px 0 0;
-webkit-background-clip: padding-box;
-moz-background-clip: padding;
background-clip: padding-box;
}
// Because offset-anchor causes sections to overlap the bottom of previous ones,
// we need to put content higher so links aren't blocked by the transparent border.
.container {
position: relative;
z-index: 1;
}
Solutions with changing position property are not always possible (it can destroy layout) therefore I suggest this:
HTML:
<a id="top">Anchor</a>
CSS:
#top {
margin-top: -250px;
padding-top: 250px;
}
Use this:
<a id="top"> </a>
to minimize overlapping, and set font-size to 1px. Empty anchor will not work in some browsers.
Borrowing some of the code from an answer given at this link (no author is specified), you can include a nice smooth-scroll effect to the anchor, while making it stop at -60px above the anchor, fitting nicely underneath the fixed bootstrap navigation bar (requires jQuery):
$(".dropdown-menu a[href^='#']").on('click', function(e) {
// prevent default anchor click behavior
e.preventDefault();
// animate
$('html, body').animate({
scrollTop: $(this.hash).offset().top - 60
}, 300, function(){
});
});
The above methods don't work very well if your anchor is a table element or within a table (row or cell).
I had to use javascript and bind to the window hashchange event to work around this (demo):
function moveUnderNav() {
var $el, h = window.location.hash;
if (h) {
$el = $(h);
if ($el.length && $el.closest('table').length) {
$('body').scrollTop( $el.closest('table, tr').position().top - 26 );
}
}
}
$(window)
.load(function () {
moveUnderNav();
})
.on('hashchange', function () {
moveUnderNav();
});
* Note: The hashchange event is not available in all browsers.
You can achieve this without an ID using the a[name]:not([href]) css selector. This simply looks for links with a name and no href e.g. <a name="anc1"></a>
An example rule might be:
a[name]:not([href]){
display: block;
position: relative;
top: -100px;
visibility: hidden;
}
Instead of having a fixed-position navbar which is underlapped by the rest of the content of the page (with the whole page body being scrollable), consider instead having a non-scrollable body with a static navbar and then having the page content in an absolutely-positioned scrollable div below.
That is, have HTML like this...
<div class="static-navbar">NAVBAR</div>
<div class="scrollable-content">
<p>Bla bla bla</p>
<p>Yadda yadda yadda</p>
<p>Mary had a little lamb</p>
<h2 id="stuff-i-want-to-link-to">Stuff</h2>
<p>More nonsense</p>
</div>
... and CSS like this:
.static-navbar {
height: 100px;
}
.scrollable-content {
position: absolute;
top: 100px;
bottom: 0;
overflow-y: scroll;
width: 100%;
}
There is one significant downside to this approach, however, which is that while an element from the page header is focused, the user will not be able to scroll the page using the keyboard (e.g. via the up and down arrows or the Page Up and Page Down keys).
Here's a JSFiddle demonstrating this in action.
This was inspired by the answer by Shouvik - same concept as his, only the size of the fixed header isn't hard coded. As long as your fixed header is in the first header node, this should "just work"
/*jslint browser: true, plusplus: true, regexp: true */
function anchorScroll(fragment) {
"use strict";
var amount, ttarget;
amount = $('header').height();
ttarget = $('#' + fragment);
$('html,body').animate({ scrollTop: ttarget.offset().top - amount }, 250);
return false;
}
function outsideToHash() {
"use strict";
var fragment;
if (window.location.hash) {
fragment = window.location.hash.substring(1);
anchorScroll(fragment);
}
}
function insideToHash(nnode) {
"use strict";
var fragment;
fragment = $(nnode).attr('href').substring(1);
anchorScroll(fragment);
}
$(document).ready(function () {
"use strict";
$("a[href^='#']").bind('click', function () {insideToHash(this); });
outsideToHash();
});
I'm facing this problem in a TYPO3 website, where all "Content Elements" are wrapped with something like:
<div id="c1234" class="contentElement">...</div>
and i changed the rendering so it renders like this:
<div id="c1234" class="anchor"></div>
<div class="contentElement">...</div>
And this CSS:
.anchor{
position: relative;
top: -50px;
}
The fixed topbar being 40px high, now the anchors work again and start 10px under the topbar.
Only drawback of this technique is you can no longer use :target.
Adding to Ziav's answer (with thanks to Alexander Savin), I need to be using the old-school <a name="...">...</a> as we're using <div id="...">...</div> for another purpose in our code. I had some display issues using display: inline-block -- the first line of every <p> element was turning out to be slightly right-indented (on both Webkit and Firefox browsers). I ended up trying other display values and display: table-caption works perfectly for me.
.anchor {
padding-top: 60px;
margin-top: -60px;
display: table-caption;

I added 40px-height .vspace element holding the anchor before each of my h1 elements.
<div class="vspace" id="gherkin"></div>
<div class="page-header">
<h1>Gherkin</h1>
</div>
In the CSS:
.vspace { height: 40px;}
It's working great and the space is not chocking.
how about hidden span tags with linkable IDs that provide the height of the navbar:
#head1 {
padding-top: 60px;
height: 0px;
visibility: hidden;
}
<span class="head1">somecontent</span>
<h5 id="headline1">This Headline is not obscured</h5>
heres the fiddle: http://jsfiddle.net/N6f2f/7
You can also add an anchor with follow attr:
(text-indent:-99999px;)
visibility: hidden;
position:absolute;
top:-80px;
and give the parent container a position relative.
Works perfect for me.
A further twist to the excellent answer from #Jan is to incorporate this into the #uberbar fixed header, which uses jQuery (or MooTools). (http://davidwalsh.name/persistent-header-opacity)
I've tweaked the code so the the top of the content is always below not under the fixed header and also added the anchors from #Jan again making sure that the anchors are always positioned below the fixed header.
The CSS:
#uberbar {
border-bottom:1px solid #0000cc;
position:fixed;
top:0;
left:0;
z-index:2000;
width:100%;
}
a.anchor {
display: block;
position: relative;
visibility: hidden;
}
The jQuery (including tweaks to both the #uberbar and the anchor approaches:
<script type="text/javascript">
$(document).ready(function() {
(function() {
//settings
var fadeSpeed = 200, fadeTo = 0.85, topDistance = 30;
var topbarME = function() { $('#uberbar').fadeTo(fadeSpeed,1); }, topbarML = function() { $('#uberbar').fadeTo(fadeSpeed,fadeTo); };
var inside = false;
//do
$(window).scroll(function() {
position = $(window).scrollTop();
if(position > topDistance && !inside) {
//add events
topbarML();
$('#uberbar').bind('mouseenter',topbarME);
$('#uberbar').bind('mouseleave',topbarML);
inside = true;
}
else if (position < topDistance){
topbarME();
$('#uberbar').unbind('mouseenter',topbarME);
$('#uberbar').unbind('mouseleave',topbarML);
inside = false;
}
});
$('#content').css({'margin-top': $('#uberbar').outerHeight(true)});
$('a.anchor').css({'top': - $('#uberbar').outerHeight(true)});
})();
});
</script>
And finally the HTML:
<div id="uberbar">
<!--CONTENT OF FIXED HEADER-->
</div>
....
<div id="content">
<!--MAIN CONTENT-->
....
<a class="anchor" id="anchor1"></a>
....
<a class="anchor" id="anchor2"></a>
....
</div>
Maybe this is useful to somebody who likes the #uberbar fading dixed header!
#AlexanderSavin's solution works great in WebKit browsers for me.
I additionally had to use :target pseudo-class which applies style to the selected anchor to adjust padding in FF, Opera & IE9:
a:target {
padding-top: 40px
}
Note that this style is not for Chrome / Safari so you'll probably have to use css-hacks, conditional comments etc.
Also I'd like to notice that Alexander's solution works due to the fact that targeted element is inline. If you don't want link you could simply change display property:
<div id="myanchor" style="display: inline">
<h1 style="padding-top: 40px; margin-top: -40px;">My anchor</h1>
</div>
Here's the solution that we use on our site. Adjust the headerHeight variable to whatever your header height is. Add the js-scroll class to the anchor that should scroll on click.
// SCROLL ON CLICK
// --------------------------------------------------------------------------
$('.js-scroll').click(function(){
var headerHeight = 60;
$('html, body').animate({
scrollTop: $( $.attr(this, 'href') ).offset().top - headerHeight
}, 500);
return false;
});
I ran into this same issue and ended up handling the click events manually, like:
$('#mynav a').click(() ->
$('html, body').animate({
scrollTop: $($(this).attr('href')).offset().top - 40
}, 200
return false
)
Scroll animation optional, of course.
