It looks like the visible display of a iphone 6 is 559px in safari. The address bar and bottom tool bar taking up some real estate. How do you get the visible height (559px) using javascript or jquery?
run the snippet and inspect with developer for iphone 6,7,and 8

window.innerHeight should give the visible height of the screen.

JSFiddle code not working in my own page
(3 answers)
Closed 5 years ago.
Sorry, not quite the same as previously asked versions of this. I've tried those solutions to no avail.
I have worked with some folks to iron out some issues with a snippet we were working on. Finally got it working on JSfiddle how we need it, but for whatever reason, it's not working on a plain HTML site. The content looks to load, but the preview doesnt work after choosing an image.
Here is the JSfiddle working here: http://jsfiddle.net/ELcf6/568/
Here is all of the code pieces compiled into a single page for testing. This is the example that seems to not work. Does JSfiddle inject any pre-requisites that I might be missing?
Any help in figuring this out would be greatly appreciated.

Your script is running before the DOM has loaded and that's why you are getting the "Cannot read property 'addEventListener' of null" error.
Move the script so that it is just before the close of the body tag.

Tried the best I could and did some research, I still couldn't figure it out.
My goal is to create an easy coded lightbox for a part of my final examination website that im working on.
Please need help with this annoying problem of mine, would be very appreciated!

If the problem is the click handler, try attaching the event listener globally like so, this way should work even if the element is created after the listener. (Otherwise the duplicate comment on your question should solve the issue)
$(document).ready(function () {
$(document).on('click', '#lb-shadow', function(){
$('#lb-container').fadeOut(6000);
$('#lb-shadow').fadeOut(6000);
$('#lb-container').detach();
$('#lb-shadow').detach();
});
$('button').click(function() {
$('body').append('<div id="lb-shadow"><p id="lb-x">[ x ]</p></div>');
$('body').append('<div id="lb-container"></div>');
$('#lb-shadow').fadeIn(6000);
$('#lb-container').fadeIn(6000);
});
});
I solved it!
I just added display:block on the lb-container and lb-shadow. Apperently the fade effects trigger it automatically and I did cut down my js code aswell.
$(document).ready(function () {
$('button').click(function() {
$('body').append(' <div id="lb-shadow"><p id="lb-x">[ x ]</p></div> ');
$('body').append(' <div id="lb-container"></div> ');
$('#lb-shadow').fadeIn();
$('#lb-container').fadeIn();
$('#lb-shadow').click(function(){
$('#lb-container').fadeOut();
$('#lb-shadow').fadeOut();
});
});
});
I'm having a problem with my mobile/tablet device orientation.
So i'm trying to show a div when the device is held in landscape, but not when it's held in portrait. It works when i reload the site in portrait and turn it to landscape, but if i refresh in landscape, then the div dosen't show anymore?
my Js.
window.addEventListener("orientationchange", function() {
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent)){
if(window.innerWidth > window.innerHeight){
$('#rotate').css({display: "block"});
}else{
$('#rotate').css({display: "none"});
}
}
}, false);
my Css
#media only screen and (max-width:768px){
#rotate{
width:100vw;
height:100vh;
z-index:1000;
position:fixed;
top:0;
left:0;
display:none;
background-color:#F8F8F8;
}
}
Hope sombody can help me! Thanks
If you can use only JavaScript this solutions seems to be more elegant and works every time the page is refreshed

I saw a fiddle. When cursor is hovering over it, it animates from bottom to top.
How could I change it, so that on click, it would animate from right to left, and after that, the content would be hidden? When the content is hidden, there would be a button, where I could click to have the content show up again.
HTML
<html>
<body>
<div class="wrapper">
<div class="inner">
Sliding div here!! Yay!!
</div>
</div>
<p>Hover over red div please!!</p>
</body>
</html>
CSS
.wrapper{
background-color:red;
width:200px;
height:200px;
position:relative;
overflow:hidden;
color:white;
}
.inner{
width:200px;
height:100px;
position:absolute;
background-color:black;
margin-top:200px;
color:white;
}
jquery
$(document).ready(function(){
var innerHeigth = $(".inner").outerHeight();
$(".wrapper").hover(function(){ $(".inner").stop().animate({top:-innerHeigth},1000);
//alert(innerHeigth)
},function(){
$(".inner").stop().animate({top:0},1000);
});
});
and here is the fiddle http://jsfiddle.net/qGVfp/
There's 2 changes you need to make. First adjust the stylesheet so the moving div is off to the left instead of the bottom:
.inner{
width:200px;
height:100px;
position:absolute;
background-color:black;
left:-200px;
color:white;
}
And then change the javascript to react to clicks, be based on width and modify the left property. Note, there is a toggle method that behaves a lot like hover, but it's getting removed from jQuery, so you have to have a boolean that tracks state.
$(document).ready(function(){
var width = $(".inner").width();
var toggle = true;
$(".wrapper").click(function(){
if(toggle) {
$(".inner").stop().animate({left:0},1000);
} else {
$(".inner").stop().animate({left:-width},1000);
}
toggle = !toggle;
});
});
Here's an updated fiddle: http://jsfiddle.net/qGVfp/30/
.wrapper2{
background-color:blue;
width:400px;
height:200px;
position:relative;
overflow:hidden;
color:white;
}
.inner2{
width:200px;
height:200px;
position:absolute;
background-color:black;
margin-left:400px;
color:white;
}
$(".wrapper2").hover(function(){
$(".inner2").stop().animate({marginLeft:200},1000);
//alert(innerHeigth)
},function(){
$(".inner2").stop().animate({marginLeft:400},1000);
});
});

You are basically there just need to change a few things around.
HTML
<!DOCTYPE html>
<html>
<body>
<div class="wrapper">
<div class="inner">
Sliding div here!! Yay!!
</div>
</div>
<button id="btn">click</button>
</body>
</html>
CSS
.wrapper {
background-color:red;
width:200px;
height:200px;
position:relative;
overflow:hidden;
color:white;
}
.inner {
width:200px;
height:100px;
position:absolute;
background-color:black;
left:200px;
color:white;
}
SCRIPT
var hidden = true;
$(document).ready(function(){
$("#btn").click(function() {
if(hidden) {
$(".inner").stop().animate({left:0}, 1000);
hidden = false;
}
else {
$(".inner").stop().animate({left:200},1000);
hidden = true;
}
});
});
Here is a fiddle to show this: http://jsfiddle.net/qGVfp/31/
I'm trying to make an image appear when you roll over text on the bottom right side of the screen. How do I get it down there for all screen widths and heights?
you can use fixed positioning on the image and assign the left,top, right or bottom attributes to suit your needs see: http://www.w3schools.com/css/css_positioning.asp for an example
This'll work:
<style type="text/css">
img.floating {
position: absolute;
bottom: 0px;
left: 0px;
}
</style>
<img class="floating" src="url to image" />
:hover doesn't work for IE6 unless it's being used on a link. Use this.
<style type="text/css">
#myFavoriteFooterImage {
bottom:0px;
right:0px;
position:fixed;
display:none;
}
</style>
<script type="javascript">
document.getElementById("mousyTextFunTime").onmouseover = function(){
document.getElementById("myFavoriteFooterImage").style.display = "";
};
document.getElementById("mousyTextFunTime").onmouseout = function(){
document.getElementById("myFavoriteFooterImage").style.display = "none";
};
</script>
<div id="mousyTextFunTime">Text to mouse over</div>
<img id="myFavoriteFooterImage" />
Create a CSS style for :hover on the text.
<style type="text/css">
#bottom { display:none; }
#text:hover #bottom {
display:block;
position:absolute;
left:0; // how far from the left
bottom:0;
}
</style>
<div id="text>TEXT</div>
<img src="bottomimage.jpg" id="bottom">
