how would i make a link show text - javascript

I have a very simple page I want to be able to show text from a link.
Here is my webpage:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Encyclopedia</title>
<link href="test.css" rel="stylesheet" type="text/css">
</head>
<body>
<h1>This is our Encyclopedia about animals</h1>
<p>Hello this is our Animal encyclopedia so far were still working hard to make it equal to other websites we do have a very small selection of animals you can learn about right now. It's really vauge but if you click sign up you can get updates straight
to your email for when we have a more updated selection
</p>
<nav id=n av1>
<ul>
<li>Home</li>
<li>Image gallery</li>
<li>SignUp</li>
</ul>
</nav>
<nav id=n av3>
<ul>
<li>Marine life</li>
<li>Mammals</li>
<li>Birds</li>
<li>Reptiles</li>
<li>Amphibians</li>
</ul>

I want the links about animals to show text I know right now I got it set up to go to the page its already on. But how would I go about doing it so that when I click the link text about the topic appears on the page?

Lots of ways to do it but here's a simple way
You'll need a DIV to fill with text
<div id="uniquename3" style="display:none; position:absolute; border-style: solid; background-color: white; padding: 5px;width:120px;">Content goes here.</div>
On the Href's you'll need something like this.
<a onmouseover="document.getElementById('uniquename3').innerHTML = 'Mammels\,some interesting info about mammels\, more interesting info about mammels';ShowContent('uniquename3'); return true;" onmouseout="HideContent('uniquename3'); return true;" href="javascript:ShowContent('uniquename3')">Mammels</a>

var cX = 0; var cY = 0; var rX = 0; var rY = 0;
function UpdateCursorPosition(e){ cX = e.pageX; cY = e.pageY;}
function UpdateCursorPositionDocAll(e){ cX = event.clientX; cY = event.clientY;}
if(document.all) { document.onmousemove = UpdateCursorPositionDocAll; }
else { document.onmousemove = UpdateCursorPosition; }
function AssignPosition(d) {
if(self.pageYOffset) {
rX = self.pageXOffset;
rY = self.pageYOffset;
}
else if(document.documentElement && document.documentElement.scrollTop) {
rX = document.documentElement.scrollLeft;
rY = document.documentElement.scrollTop;
}
else if(document.body) {
rX = document.body.scrollLeft;
rY = document.body.scrollTop;
}
if(document.all) {
cX += rX;
cY += rY;
}
d.style.left = (cX+10) + "px";
d.style.top = (cY+10) + "px";
}
function HideContent(d) {
if(d.length < 1) { return; }
document.getElementById(d).style.display = "none";
}
function ShowContent(d) {
if(d.length < 1) { return; }
var dd = document.getElementById(d);
AssignPosition(dd);
dd.style.display = "block";
}
function ReverseContentDisplay(d) {
if(d.length < 1) { return; }
var dd = document.getElementById(d);
AssignPosition(dd);
if(dd.style.display == "none") { dd.style.display = "block"; }
else { dd.style.display = "none"; }
}

Here's an example of using js to show and hide elements based on which link is clicked.
const app = {
init: function() {
document.querySelectorAll(".link").forEach(link => {
link.addEventListener("click", app.nav);
});
},
nav: function(ev) {
ev.preventDefault();
let currentPage = ev.target.getAttribute("data-target");
let content = document.querySelectorAll('.content')
for(i = 0; i < content.length; i++) {
if(content[i].classList.contains('showing')) {
content[i].classList.remove("showing");
}
}
document.getElementById(currentPage).classList.add("showing");
}
};
document.addEventListener("DOMContentLoaded", app.init);
.content {
display: none;
}
.showing {
display: block;
}

It's hard to explain using words, better look at example i made.

I have the navbar that i hide on scrolling page down and show on scrolling up.
I need to make an element (lets call it FILTER) that on page load is located in hero-section but become sticky to navbar when scrolling to FILTER position or below and vice versa when scrolling up.
I solved the problem in my way but i wonder if any better solution exists? Is it necessary to clone FILTER element?
I think there is a better solution than cloning the element, you can use this code:

JS:
let filter = document.getElementsByClassName("filter")[0];
let fixed = false;
let filterTop = filter.getBoundingClientRect().top + window.scrollY;
window.addEventListener("scroll", function() {
if (filter.getBoundingClientRect().top <= 50 && !fixed) {
filter.style.position = 'fixed';
filter.style.top = '50px';
fixed = true;
} else if (window.scrollY <= filterTop - 50 && fixed) {
filter.style.position = 'static';
filter.style.top = '';
fixed = false;
}
});
What I've done here is removing the clone (and the styles related to it ) and making the position of the filter fixed or static according to the scroll.

How to make this effect work if the window is resized when page is scrolled

I have an effect that makes the header become un-fixed when a specified div hits the top of the screen, and scroll with the rest of the content.
This works perfectly and i wrapped the "const targetTopPos = targetEl.getBoundingClientRect().top" in a resize event listener. But its calculations are wrong if the page is already scrolled and i have no idea why.
Another issue is that if the page is refreshed scrolled down, the header will be there until you scroll.
Here is the code:
window.onresize = function(event) {
const targetTopPos = targetEl.getBoundingClientRect().top;
console.log(targetTopPos);
};
const headerEl = document.querySelector('header')
const targetEl = document.querySelector('#target')
const targetTopPos = targetEl.getBoundingClientRect().top
let isHeaderFixed = true
document.onscroll = () => {
const targetTopOffset = targetEl.getBoundingClientRect().top
if (isHeaderFixed && targetTopOffset < 100) {
headerEl.style.position = 'absolute'
headerEl.style.top = `${targetTopPos - 100}px`
isHeaderFixed = !isHeaderFixed
}
if (!isHeaderFixed && targetTopOffset >= 100) {
headerEl.style.position = 'fixed'
headerEl.style.top = '0px'
isHeaderFixed = !isHeaderFixed
}
}
body {
padding: 0;
margin: 0;
position: relative;
}
header {
position: fixed;
height: 100px;
width: 100%;
background: lightblue;
}
.content {
line-height: 100px;
}
.target {
width: 100%;

}

I write the "targetTopPos" to the console so you can see the issue
It's because you redefine targetTopPos as a const in your onresize event.
You only have to asign the new value to targetTopPos
see code below
window.onresize = function(event) {
targetTopPos = targetEl.getBoundingClientRect().top;
console.log(targetTopPos);
};
const headerEl = document.querySelector('header')
const targetEl = document.querySelector('#target')
let targetTopPos = targetEl.getBoundingClientRect().top
let isHeaderFixed = true
document.onscroll = () => {
const targetTopOffset = targetEl.getBoundingClientRect().top
if (isHeaderFixed && targetTopOffset < 100) {
headerEl.style.position = 'absolute'
headerEl.style.top = `${targetTopPos - 100}px`
isHeaderFixed = !isHeaderFixed
}
if (!isHeaderFixed && targetTopOffset >= 100) {
headerEl.style.position = 'fixed'
headerEl.style.top = '0px'
isHeaderFixed = !isHeaderFixed
}
}
body {
padding: 0;
margin: 0;
position: relative;
}
header {
position: fixed;

Sliding text from under image

I need to show txt nicely sliding from under image after click. When user will click on other image, previous text have to slide out (not be vissible).
I am not good in javascript at all. Now I have something like this:

Could someone help me with this one?
When using jquery hide() and show() you can set the parameter duration that will be used in animation duration, see jquery docs. For example, 500 miliseconds:
$(document).ready(function() {
$(".slidingDiv").hide();
$(".show_hide").show();
$('.show_hide').click(function() {
//hide all sliding divs
var arrayLikeOfSlidingDivs = $('.slidingDiv');
arrayLikeOfSlidingDivs.each(function(){
if ($(this).is(':visible')){
$(this).hide(500);
}
});
var isvisible = $(this).next('.slidingDiv').is(':visible');
if ( isvisible ) {
$(this).next('.slidingDiv').hide(500);
} else{
$(this).next('.slidingDiv').show(500);
}
});
});

How do I get pageYoffset on a mobile browser

I need to keep track of the page offset on a website.
var supportPageOffset = window.pageXOffset !== undefined;
var isCSS1Compat = ((document.compatMode || "") === "CSS1Compat");
var Y = supportPageOffset ? window.pageYOffset : isCSS1Compat ? document.documentElement.scrollTop : document.body.scrollTop;
Using the above code returns the vertical offset for me on all desktop browsers. However, I only get 0 on mobile browsers. How can I get the scroll location on mobile?
I guess this might help you:
Demo : Fiddle
JQuery
$(window).scroll(function (event) {
var scroll = $(window).scrollTop(); // This would give you offsetY while you scroll
$(".scrollY").text(scroll); // This is just to display for instance.
});
Open in Mobile
Update
JavaScript
window.addEventListener('scroll', function(){
var scrollTop = (window.pageYOffset !== undefined) ? window.pageYOffset : (document.documentElement || document.body.parentNode || document.body).scrollTop;
document.getElementsByClassName("scrollY")[0].innerHTML = scrollTop;
}, true)
.scrollY

Open a multi open accordion tab and scroll to a hash location within that section (IE scrolling to hash anchor before evaluating query string?)

How can I create links that will expand a particular accordion section and then scroll to a particular DIV within that section?
I'm using the latest jQuery UI library as well as jquery.multi-accordion-1.5.3.js, and developing for IE8 or later
I've been able to successfully implement both multiAccordion and by parsing a query string I can manipulate which section to be expanded, and scroll to the first hash anchor.
Strangely, this seems to work only for the first link, for any other link it scrolls past the corresponding hash anchor, and overall it acts erratically.
I came across a few threads mentioning IE having issues recognizing hash anchors in a query string like this index.php?page=page1#section3 , ie...Why does Internet Explorer not support bookmarks with both a querystring and a hash/anchor? Firefox works properly but I have not come across one solution...
Has anyone have a solution for this? Any alternatives?
Here is my code (or if it's more legible for you - the fiddle with the same code http://jsfiddle.net/3QSmq/1/)

Any suggestions?
P.S. Here is THE closest description of my issue elsewhere on the web but no answer...Another thread
Instead of including the tab with the page, just target the ID from the hash. So your links will look like this:
SOMETHING<br />
SOMETHING1
Then you can include this code to find the ID from the hash, find the correct tab and open it. Here is the complete code & demo:
$(function() {
var updateAccordion = function(hash) {
hash = hash || window.location.hash;
var content, tab;
// look for a hash
if (hash && $(hash).length) {
// find accordion content
content = $(hash).closest('.ui-accordion-content');
if (content.length) {
// find "tab#" from <a> inside of accordion header (h3)
tab = parseInt(content.prev('h3').find('a').attr('id').replace('tab',''), 10) - 1;
$('#multiAccordion').multiAccordion("option", "active", [tab]);
}
}
};
// intercept all clicked links and look for a hash
$('a').click(function(){
if (this.hash) {
updateAccordion(this.hash);
}
});
$('#multiAccordion').multiAccordion({
active: [1],
click: function(event, ui) {
//console.log('clicked')
},
init: function(event, ui) {
//console.log('whoooooha')
},
tabShown: function(event, ui) {
//console.log('shown')
},
tabHidden: function(event, ui) {
//console.log('hidden')
}
});
// open up accordion to correct tab after initialization
updateAccordion();
});​
Try using document.location.hash to access directly the hash parameters.
In your example :
index.html?page=tab2#something
document.location.search will be ?page=tab2
document.location.hash will be #something
You are trying to parse the wrong value, so I guess the JQuery plugin scroll to the bottom of the page when it's trying to open a tab that doesn't exists.
