I'm creating a navigation with a sliding bar/box that follows the mouse. I manage to animate the box I'm having trouble to move the box to follow the mouse. ex. if the mouse is in nav1 the box would slide to nav1 from wherever nav the box is currently place.
I made a example jsfiddle: http://jsfiddle.net/5Wrcr/
HTML
<div id="nav" style="margin: 0 auto; width: 500px; background: red;">
<div id="nav1"></div>
<div id="nav2"></div>
<div id="nav3"></div>
<div id="nav4"></div>
<div id="movers"></div>
</div>
CSS
#nav1, #nav2, #nav3, #nav4 {
width: 98px;
height: 48px;
border: thin solid black;
float: left;
}
#movers {
width: 100px;
height: 50px;
background: blue;
display: none;
position: absolute;
opacity: 0.3;
}
#nav:hover > #movers {
display: block;
}
JS
$(document).ready(function(){
$("#nav").hover(function(){
$('#movers').stop().animate({'margin-left': '300px'}, 500);
});
});
I don't know what animation showing that code. But if you want to use margin left animation then you can use:
$(document).ready(function()
{
$('#nav').hover(function()
{
$('#movers').animate({
margin-left: '300px'
});
});
});
not tested but should work...
Try this DEMO
$(document).ready(function(){
$("#nav div").hover(function(){
var a =$(this).position();
$('#movers').stop().animate({'margin-left': (a.left-29)+'px'},500);
});
});
Try this.
$("#nav div").hover(function(){
$('#movers').stop().animate({
'left': $(this).offset().left
}, 500);
});

First, thanks for reading my question. I'm trying to make grid of 3 images that slide over each other when a user hovers over it. I've seen this on many websites but I don't know what this effect/plugin is called. So I made a image and a fiddle of what I'm trying to accomplish.
The start:
3 images positioned horizontally. The first image is almost completely visible except for some tab-like bars on the right. When you would hover over the second image it will slide to the left leaving only a small (again) tab-like bar on the right. The same goes for the third image. See this image I've made.
If a user doesn't hover any of the images it just goes back to the default of showing the first image and the second and third image in tab-like state.
I've also made a fiddle here to show the way the images should be animated.
But as you can see this is not perfect. Does anyone here have a snippet I could use because my jQuery skills are not there yet. But I think this (should) could be accomplished easier and with less code I think? And even maybe more elegantly.
Thanks for the (long) read...
This is simple example ;]
$('li').hover(function() {
$(this).addClass('active');
}, function(){
$(this).removeClass('active');
})
li {
width: 0;
padding: 15px;
float: right;
height: 300px;
overflow: hidden;
cursor: pointer;
color: #fff;
}
li:nth-child(1) {
background: red;
}
li:nth-child(2) {
background: green;
}
li:nth-child(3) {
background: blue;
}
li.active {
width: 400px;
transition: all 1s;
}
ul {
list-style: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>page 1</li>
<li>page 2</li>
<li>page 3</li>
</ul>
Try zAccordian jquery plugin. https://natearmagost.github.io/zaccordion/index.html
So I changed your example a bit:
What I did was:
Changed positions to relative and set overflow hidden to .wrapper
$(document).ready(function(){
$(".img-1").hover(function(){
$('.img-2').stop().animate({'left': '160px'}, 500);
$('.img-3').stop().animate({'left': '180px'}, 500);
}, function(){
$('.img-2').stop().animate({'left': '160px'}, 500);
$('.img-3').stop().animate({'left': '180px'}, 500);
});
$(".img-2").hover(function(){
$('.img-2').stop().animate({'left': '20px'}, 500);
}, function(){
$('.img-2').stop().animate({'left': '160px'}, 500);
});
$(".img-3").hover(function(){
$('.img-2').stop().animate({'left': '20px'}, 500);
$('.img-3').stop().animate({'left': '40px'}, 500);
}, function(){
$('.img-3').stop().animate({'left': '180px'}, 500);
$('.img-2').stop().animate({'left': '160px'}, 500);
});
});
.img-1 {position:relative;top:0px; background-color:red; width: 200px; Height: 50px;}
.img-2 {position:relative;top:-50px;left:160px; background-color: #1F6; width: 200px; Height: 50px;}
.img-3 {position:relative;top:-100px;left:180px; background-color: #0FF; width: 200px; Height: 50px;}
.wrapper {
border: black 1px solid;
width: 200px;
Height: 50px;
position:relative;
overflow: hidden;
top:0px
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="wrapper">
<div class="img-1">
</div>
<div class="img-2">
</div>
<div class="img-3">
</div>
</div>
You can do this completely with CSS, no need for javascript.
The example below manipulates the z-index when a div is hovered. The only tricky one is the hover of 'image-3'. The z-index of 'image-2' needs to be changed also to ensure it is on top of 'image-1'.
Therefore, in the HTML 'image-2' is placed after 'image-3'. Than in CSS 'image-2' can be addressed as a sibling.
[class^="img"] {
position: absolute;
top: 0;
left: 0;
}
.img-1 {
z-index: 3;
}
.img-1 img {
border: 6px solid #FF0;
}
.img-2 {
left: 20px;
z-index: 2;
}
.img-2 img {
border: 6px solid #F00;
}
.img-3 {
left: 40px;
z-index: 1;
}
.img-3 img {
border: 6px solid #F60;
}
div[class^="img"]:hover {
z-index: 5;
}
.img-3:hover+.img-2 {
z-index: 4;
}
<div class="wrapper">
<div class="img-1">
<img src="//placehold.it/200x50&text='image-1'" alt="">
</div>
<div class="img-3">
<img src="//placehold.it/200x50&text='image-3'" alt="">
</div>
<div class="img-2">
<img src="//placehold.it/200x50&text='image-2'" alt="">
</div>
</div>
I am trying to repeatedly move a div to the right using requestAnimationFrame and Jquery's animate(). However, my div seems to stutter instead of continuously move. How come it keeps starting and stopping?
Here is a JSfiddle of my implementation
If you want to just see my code here is the html:
<body>
<div id="back">
<div id="myDiv">
</div>
</div>
</body>
The css:
#myDiv {
height: 50px;
width: 50px;
background-color: black;
position: absolute;
}
#back {
height: 200px;
width: 200px;
background-color: teal;
}
And the javascript:
function updateFrame(){
$("#myDiv").animate({left: '+=25px'}, function(){
window.requestAnimationFrame(updateFrame);
});
}
updateFrame();
Try this:
function updateFrame(){
$("#myDiv").animate({left: '+=1px'}, 10, function(){
window.requestAnimationFrame(updateFrame);
});
}
updateFrame();
use left: 1px instead of 25px then use animate speed.
jsFiddle
I have two block inside container and under them button. I need, when I click on the button, then the first div slowly moves up and removed. I tried so:
HTML:
<div class="container">
<div class="block"></div>
<div class="block"></div>
</div>
<button class="move">Click</button>
CSS:
.container {
border: 2px solid blue;
display: inline-block
}
.block {
width: 100px;
height: 100px;
background: red;
margin: 5px;
}
.move {
display: block
}
jQuery:
$(document).ready(function() {
$('.move').click(function() {
$('.block:first-child').animate({scrollTop: '-100px'}, 1000, function() {
$(this).remove();
});
});
});
But when I click on the button, then first .block just removed. I need to first move it up. How to fix it?
JSFiddle
You're animating the scrollTop of the element which will not have the effect you want. You can animate the height instead. However there is also the slideUp() function which will do this for you. Try this:
$('.move').click(function() {
$('.block:first-child').slideUp(function() {
$(this).remove();
});
});
Example fiddle
If you have to do it without resizing the block, you can set overflow: hidden on the container, then animate the margin-top of the block itself.
Example fiddle
Add position: relative to element. top property works on positioned elements that is position is anything other than static. position: relative suits in this case.
$(document).ready(function() {
$('.move').click(function() {
$('.block:first-child').animate({
top: '-100px'
}, 1000, function() {
$(this).remove();
});
});
});
.container {
border: 2px solid blue;
display: inline-block
}
.block {
width: 100px;
height: 100px;
background: red;
margin: 5px;
position: relative
}
.move {
display: block
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="block"></div>
<div class="block"></div>
</div>
<button class="move">Click</button>
I just want the cursor to stay a pointer when it passes over the text in my div. Using cs, it works, but using Jquery it reverts to the text selector over text.
This doesn't work...
<style>
#test
{
height: 300px;
width: 300px;
background: blue;
position:absolute;
top: 0px;
left: 0px;
font-size: 80px;
}
</style>
</head>
<body>
<div id="test">It's not a pointer!</div>
<script src='jquery-1.10.2.min.js'>
</script>
<script>
$(document).ready(function(){
$("#testjquery").hover(function(){
$(this).css({'cursor':'hand', 'cursor':'pointer'});
});
});
</script>
While this works fine...
<style>
#test
{
height: 300px;
width: 300px;
background: blue;
position:absolute;
top: 0px;
left: 0px;
font-size: 80px;
}
#test:hover
{
cursor: pointer;
cursor: hand;
}
</style>
</head>
<body>
<div id="test">It's a pointer!</div>
It seems weird, as I thought jquery simply accessed the css methods.
Looking for an explanation, or better yet a solution w/ how to do this in Jquery.
Thanks!
Your div id is test not testjquery
$("#test").hover(function () {
$(this).css({
'cursor': 'hand',
'cursor': 'pointer'
});
});
Update you can only use
$("#test").hover(function () {
$(this).css({
'cursor': 'pointer'
});
});

What I am doing wrong?
When you click on class divtop, it should show a div popup in the middle of the page. At that time back page should become not clickable. escape or a button in popup will close it.

Fiddle
I added some CSS to your #popup and it's now all in the CSS (not inline in the html). Changed also your jQuery animate to 50px, instead of just 50.
I think you have small adjustments to do to the CSS, like in .localmenu I'm not sure why you have both padding-top: 25px; margin-top: 100px;.
CSS
#popup {
position:absolute;
display: none;
float: left;
left:30%;
z-index:1;
}
#popoverlay {
position: fixed;
display:none;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: #000;
opacity: 0.5;
}
jQuery
$(document).ready(function () {
$('.divtop').click(function () {
$('#popoverlay').show();
$('#popup').show().css("top", "500px").animate({
top: "50px"
}, 200);
$('.mainContent').css("background-color", "grey");
});
$('#btnHide').click(function () {
$('#popup').hide();
$('#popoverlay').hide();
});
});
HTML
<div class="appContent">
<div class="maincontent">
<div class="divtop">Top</div>
<div class="divtop divbottom">Bottom</div>
</div>
<div id="popup">
<div class='localmenu'>Text in Div Popup
<br/>
<button id="btnHide">Close</button>
<br/>
</div>
</div>
</div>
To get it to work properly, even if there is a vertical scroll bar, you have to use position "fixed". Place popup as a direct child of body and make it's position: fixed, and width and height 100%. Place localmenu as a direct child of body as well. Working example at jsbin.
Html:
<div id="popup">
<!--// This is to stop the user from interacting with the content in the back
// and to give a visual clue about that
-->
</div>
<div class='localmenu'>
<div>
Text in Div Popup<br/>
<button id="btnHide">Close</button><br/>
</div>
</div>
<div class="appContent" >
<div class="maincontent" >
<div class="divtop" >Top</div>
<div class="divtop divbottom" >Bottom</div>
</div>
</div>
CSS:
//Use opacity to give a visual clue. Please note that this doesn't work in -all- browsers
#popup {
position: fixed;
width: 100%;
height: 100%;
display: none;
background: black;
opacity: .5;
top: 0;
left: 0;
}
//This is just to be able to center the actual menu
.localmenu {
top: 20%;
left: 0;
width: 100%;
position: fixed;
height: 150px;
display: none;
}
.localmenu > div {
border: 1px solid blue;
background: #fff;
margin-left : auto;
margin-right: auto;
width: 300px;
height: 150px;
}
Javascript: (This is mostly the same, although I removed the animate, because I don't know exactly how it works and it needs to end at 'top: 0'. As localmenu and popup are seperate, we show them seperate as well.)
$(document).ready(function() {
$('.divtop').click(function() {
$('#popup').show().animate(200);
$('.localmenu').show();
//$('.mainContent').css("background-color", "grey");
});
$('#btnHide').click(function() {
$('#popup').hide();
$('.localmenu').hide();
});
});
To block the div tags at the back from being clickable:
Add a div with the following style in your HTML. Im gonna call it overlay.
.overlay {
width: 100%;
height: 100%;
background-color: #000;
left: 0;
opacity: .8;
position: absolute;
top: 0;
z-index: 10000;
display: none;
}
This will essentially cover up your page when shown up.
To center your popup:
I added some extra styles to #popup and removed some from .localmenu. You were missing position: absolute and z-index, added those in. (z-index of popup must be > z-index of overlay)
#popup {
background: #fff;
position :absolute;
left : 40%;
width : 300px;
height: 600px;
height: 150px;
display: none;
z-index: 10001;
}
.localmenu
{
border: 1px solid black;
}
Then, in your JS,
In your animate method, I changed 50px to 30% to center div#popup
Added code to hide and show .overlay along with #popup.
After the changes,
$(document).ready(function () {
$('.divtop').click(function () {
$('#popup').show().css("top", "500px").animate({
top: "30%"
}, 200);
$('.overlay').show();
});
$('#btnHide').click(function () {
$('#popup,.overlay').hide();
});
});

Code

Try this:
$(document).ready(function() {
$('.divtop').click(function() {
var div = $('.appContent');
$('.localmenu').css({'margin': '200px auto'});
$('#popup').show().css({top: "500px", position: 'absolute', width: div.width(), height: div.height()}).animate({top: 0}, 200);
$('.mainContent').css("background-color", "grey");
});
$('#btnHide').click(function() {
$('.mainContent').css("background-color", "");
$('#popup').hide();
});
});
