jQuery animate movement left and right - javascript

Using jquery's .css() i am changing the left attributes value to move a div left or right. Im looking for a way to animate this change as it occurs. Nothing ive tried is working, ive tried jQueryUI's .show(slide) function, but this moves the whole div, rather than just the 120px movement i need.
This is my current function which is working without an animation:
$('#plrt').live("click",function(){
var lm=$('.plwid').css("left");
lm = (parseInt(lm) + 120);
$('.plwid').css("left", lm);
});
this is the slide function, it does not work properly as the whole div goes from display:hide to display:show, rather than just moving the pixel change

try animate()
$('#plrt').on("click",function(){
$('.plwid').animate({ left: '+=120' }, 400 );
});

I have whipped up a quick example of what I think you are trying to achieve.
You should check out jQuery Animate.
//note live is deprecated
$('#plrt').on("click", function() {
//perform custom animation to add 120px to current left CSS position
$('.plwid').animate({
left: '+=120'
});
});
#plrt{
position:relative;
background:red;
width:100px;
height:100px;
cursor:pointer;
}
.plwid{
position:absolute;
background:blue;
width:100px;
height:100px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div id="plrt"></div>
<div class="plwid"></div>

try this http://api.jquery.com/animate/
$('#plrt').on('click', function() {
$('.plwid').animate({ left: '+=120', 5000 });
});

Animate text using intervals (and timeouts?) Javascript, JQuery

I would like to make a Text run from left to right in a loop. Here is the fiddle with my attempt:
https://jsfiddle.net/9Lruxym8/33/
I started with css #keyframes but I think I need the width of the text itself if I want the text to run seamlessly. My idea was to write down the text two times and once the div with the texts has run exactly halfway, the animation starts again.
After #keyframes didn't work, I tried jQuery animation. It did work somewhat but didn't run smoothly. Now I'd like to do it via transition. I thought a combination of intervals and timeouts could do the trick but I still don't get it to work - and now, I don't know why. Does anyone have a hit for me?
function runText() {
var text_width = $('#runningP').width()/2;
console.log(text_width)
setInterval(function(){
console.log("interval");
$('.text').css({'transition':'margin-left 5s'});
$('.text').css({'margin-left':'-' + text_width + 'px'});
moveBack();
}, 3000);
function moveBack() {
console.log("timeout")
setTimeout(function(){
$('.text').css({'transition':'none'});
$('.text').css({'margin-left': 0});
}, 3000);
}
}
runText();
I've recently made a bit of custom code for this functionality.
Looking at my code, it seems a bit much having essentially 3 "levels" (.scrollTextWrap > .scrollingText > .scrollContent) but this was the structure I ended up using to get a clean and consistent effect.
I've added in an initialiser too so that you could simply add the scrollMe class and have them setup the html for you
In the snippet I've added a .parentContainer purely to show how it works when constrained
$(document)
.ready(function(){
// check that scrollingText has 2 scrollContent element
$('.scrollMe')
.each(function(){
initScrollingText($(this));
});
});
function initScrollingText($this){
// store text
var text = $this.text();
// empty element
$this.html(null);
var $wrap = $('<div class="scrollTextWrap" />'),
$text = $('<div class="scrollingText" />'),
$content = $('<div class="scrollContent" />');
// set content value
$content.text(text);
// duplicate content
$text
.append($content)
.append($content.clone());
// append text to wrap
$wrap.append($text)
// add $wrap to DOM
$wrap.insertAfter($this);
// remove old element
$this.remove();
}
/* to simulate width constraints */
.parentContainer {
width: 140px;
position:relative;
overflow:hidden;
}
.scrollTextWrap {
position:relative;
width:auto;
display:inline-block;
}
.scrollingText {
display: flex;
position:relative;
transition:left 0.1s;
animation: scrollText 5s infinite linear;
}
.scrollContent {
white-space: nowrap;
padding-right:5px;
}
#keyframes scrollText {
0% { left:0 }
100% { left:-50% }
}
<div class="parentContainer">
<div class="scrollMe">Content you want to scroll goes here</div>
<!-- alternatively you can just structure the html -->
<div class="scrollTextWrap">
<div class="scrollingText">
<div class="scrollContent">Content you want to scroll goes here</div>
<div class="scrollContent">Content you want to scroll goes here</div>
</div>
</div>
</div>

How to slide a div by hovering over another div with jquery?

I have some code here and cannot find out how to make this work because I am still really new to javascript and jquery. I will have a demo below so you can see what I have going on. In the demo there is div positioned left:-60px so it is hidden, this div also has class of 'show' which positions the div to left:0 There is also the long black box which is another div. I want to make it so when you hover over the long black box, it will activate the 'show' property of the other div. Here is my code:
var $showSidemenu = $('#sidemenu');
var $sidemenuShowButton = $('#sidemenuShowButton');
function(showSidemenu){
$showSidemenu.onmouseover($sidemenuShowButton).addclass('show');
}
#sidemenuShowButton {
width:60px;
height:100%;
background:#000000;
top:0;
left:0;
position:fixed;
}
#sidemenu {
width: 60px;
height:100%;
background-color: #383D3F;
position: fixed;
top: 0;
left:-60px;
float: left;
z-index:0;
}
#sidemenu.show {
left: 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="sidemenuShowButton"></div>
<div id="sidemenu"></div>
try this jQuery:
var $showSidemenu = $('#sidemenu');
var $sidemenuShowButton = $('#sidemenuShowButton');
$(document).ready(function(){
$sidemenuShowButton.on('mouseover',function(){
$('#sidemenu').addClass("show");
});
$sidemenuShowButton.on('mouseout',function(){
$('#sidemenu').removeClass("show");
});
// to make the showed div stay while the mouse is still over it
$('#sidemenu').on('mouseover',function(){
$(this).addClass("show");
});
$('#sidemenu').on('mouseout',function(){
$(this).removeClass("show");
});
});
if you want a little animation, you can use CSS3 Transition for that, like this one:
#sidemenu {
transition: 1s;
}
HERE'S A WORKING DEMO
Use JQuery's show and hide functions. If you set your #sidemenu to display: none;. And then use this this function it will work:
$('#sidemenu').mouseenter(function(){
$("#sidemenuShowButton").show();
}).mouseleave(function(){
$("#sidemenuShowButton").hide();
});
No classes are needed in this way.
Your JS should looks like this:
var $showSidemenu = $('#sidemenu');
var $sidemenuShowButton = $('#sidemenuShowButton');
$sidemenuShowButton.on('mouseover', function(){
$showSidemenu.addClass('show')
});
First of all you are using function which never used and cannot be used since it have no name. Second, there is no onmouseover method in jQuery (read the manual ;-). Third you have to pass there a callback function which will be involved when 'mouseover' event occurs.
And if you wanna hide your div when mouse leaves add
$showSidemenu.on('mouseleave', function(){
$showSidemenu.removeClass('show')
});
You should use $showSidemenu in this case instead of $sidemenuShowButton because when $showSidemenu apears mouse leaves $sidemenuShowButton and enters $showSidemenu. But if you wanna use css3 animation - it's better to make appearing div nested to control div and use event bobbling.
And jsfiddle
Solution:Use mouseover and mouseout events to add and remove class "show"
I have intentionally added mouseout event on showSidemenu as when it slides in it goes over sidemenuShowButton div and comes on top of it, so attaching mouseout to sidemenuShowButton will cause flickering effect.
http://api.jquery.com/category/events/mouse-events/
$sidemenuShowButton.mouseover(function(){
$showSidemenu.addClass("show");
}
);
$showSidemenu.mouseout(function(){
$showSidemenu.removeClass("show");
}
);

jQuery text animation slide-in

I am trying to use jQuery slide-in animation and it seems to work fine, but my the second animation doesn't work. Can anyone tell me what I am doing wrong?
This line:
$('#headline1Txt').animate({'marginLeft': "100px"}, 1000);
is working fine, but this one:
$("#headline1Txt").animate({left: "+=30"}, 500);
is not working.
My Code
HTML
<div id="mainContainer">
<div id="headlineText">
<p id="headline1Txt" >Striped Bag</p>
</div>
</div>
JS
$(document).ready(function () {
$('#headline1Txt').animate({'marginLeft': "100px"}, 1000);
$("#headline1Txt").animate({left: "+=30"}, 500);
});
CSS
#headlineText {
margin: 60px 80px;
}
The left CSS property specifies part of the position of positioned
elements.
For absolutely positioned elements (those with position: absolute or position: fixed), it specifies the distance between the left margin
edge of the element and the left edge of its containing block.
https://developer.mozilla.org/en-US/docs/Web/CSS/left
As the CSS left property is part of position:*; property's, fix by adding the position property, so jquery knows what to increment a left value to.
In Action
CSS
#headlineText
{
margin:60px 80px;
}
#headline1Txt
{
position:relative;
}
HTML
<div id="mainContainer">
<div id="headlineText">
<p id="headline1Txt">Striped Bag</p>
</div>
</div>
jQuery
$(document).ready(function () {
$('#headline1Txt').
animate({ 'marginLeft': "100px" }, 1000).
animate({ left:"+=30" }, 5000);
});
What are you trying to achieve?
You want the text to slide in (heading right across the screen) then slide another 30px?
Thats what $("#headline1Txt").animate({ 'marginLeft': "+=30" }, 500); will achieve.
'marginLeft' not just left.
The left property of css only works with elements with absolute position. To make your animation work you have to put you element at absolute position.

Jquery effect - on mouse hover background color change;

I'm trying to create an effect that's, when the mouse over this change the background color from the left to the right.
I tried this:
http://jsfiddle.net/WVWKE/
$('#div1').mouseover(function(){
$('#back').animate({width: '200px'}, 1000);
});
$('#div1').mouseout(function (){
$('#back').animate({width: '0px'}, 1000).stop();
});
#div1{
height:200px;
width:200px;
background-color:green;
float:left;
}
#back {
width:0px;
height:200px;
background-color:Gray;
display: block;
}
<div id="div1">
<div style="position:absolute">That was amazing!</div>
<div id="back">
</div>
</div>
But, is not working correctly. If i put the mouse many times on the div, this do the effect many times and don't to.
Try to put the mouse and leave many times. The effect happens many times to.
Any help?
You are using stop incorrectly. Use it like this:
$('#div1').mouseover(function (){
$('#back').stop().animate({width: '200px'}, 1000);
});
$('#div1').mouseout(function (){
$('#back').stop().animate({width: '0px'}, 1000);
});
It's easy to understand if you think about it like it's English:
$('#back') // take "back"
.stop() // and stop it
.animate({width: '200px'}, 1000); // and animate it
Fiddle

Jquery opacity on div hover does not work

I want to show one particular div with the use of fadeTo.
If I hover over div1, then spark1 should be visible and disappear on mouseout..
But it won't do anything when hovering and I don't really know why.
HTML
<div class="spark1"></div>
<div class="div1">text</div>
CSS
.div1 {
width:300px;
height:300px;
}
.spark1 {
position:absolute;
width:27px;
height:27px;
margin-top:70px;
margin-left:395px;
background:url(../img/spark.png) no-repeat;
}
JS
$('.div1').hover(function(){
$('.spark1').fadeTo(200, 0);
});
EDIT (update)
HTML
<div class="spark1"></div>
<div class="div1"></div>
CSS
.div1 {
width:300px;
height:300px;
background-color:#000000;
}
.spark1 {
position:absolute;
width:27px;
height:27px;
top:70px;
left:395px;
background-color:#ff0000;
filter:alpha(opacity=0); opacity:0.0;
}
JS
$('.project1').hover(function(){
$('.spark1').fadeTo(200, 1);
},
function(){
$('.spark1').fadeTo(200, 0);
});
It still won't trigger, I don't get it..
you should stop the animation if the event trigger before completion of previous. try this
$('.div1').hover(function(){
$('.spark').stop(true,true).fadeTo(200, 1);
},function(){
$('.spark').stop(true,true).fadeTo(200, 0);
});
fiddle example : http://jsfiddle.net/mK4m6/11/
Your code works if you use the correct css classes names
DEMO
You define a css class .spark { } but in you code you use the class name .spark1.
Choose one or the other.
You made a mistake in your hover function. It has 2 call back methods:
$(document).ready( function() {
$(".div1").hover(
function(event) {
//hover in
$(".spark1").fadeTo(200,1);
},
function(event) {
$(".spark1").fadeTo(200,0);
});
});​
Below is a working script:
http://jsfiddle.net/U8rzJ/7/
Building on Didier's good catch of the class names, there's a problem with your hover() script. hover() can take one or two functions as arguments - if you supply just one, it's executed on both mouseover and mouseout. You'll want this, I think:
$('.div1').hover(function(){
//fade in to 100%
$('.spark').fadeTo(200, 100);
},
function(){
$('.spark').fadeTo(200, 0);
});
This fades the .spark in on mousein and fades it back out on mouseout. If you want to animate on mouseout only, I'd switch from .hover() to .mouseout().
HTML
<div class="spark1"></div>
<div class="div1">text</div>
CSS
.div1 {
width:300px;
height:300px;
}
.spark1 {
position:absolute;
width:27px;
height:27px;
top:70px;
left:395px;
background-color:#ff0000;
filter:alpha(opacity=0); opacity:.0;
}
jQuery
$('.div1').hover(function(){
$('.spark1').fadeTo(200, 1);
},
function(){
$('.spark1').fadeTo(200, 0);
});
Then it all works out.
1. Use correct class names
2. Set the initial opacity of spark1 to 0
3. On mouseenter fade the opacity to 1
4. On mouseleave fade the opacity to 0
