I want to move button left-right and right-left using jquery - javascript

I am able to move button to left side but after that how i can again move it to right side.
Can i also use delay here.
Here is the code that i have tried:
$(document).ready(function () {
example_animate(10);
});
function example_animate(px) {
$('#Button1').animate({
'marginLeft': px
});
}

you can use this, it is working perfectly for me, it will continuously move your element back and forth, and you can also vary animation speed.
function animatethis(targetElement, speed) {
$(targetElement).animate({ marginLeft: "+=10px" },
{
duration: speed,
complete: function () {
targetElement.animate({ marginLeft: "-=10px" },
{
duration: speed,
complete: function () {
animatethis(targetElement, speed);
}
});
}
)};
}
use this to implement:
animatethis($('#controlid'), 1500);

Cannot answer properly without looking at your HTML and CSS but what you are doing is right. Simply call your example_animate() with a negative value
i.e.
example_animate(-10);
Or if you want to bring it to the original value (assuming originally it had 0 margin)
example_animate(0);
Note: This is probably not the best way to animate

Yes, the animate function takes a function that is called after the animation is complete. So you can do:
$(document).ready(function () {
example_animate(100);
});
function example_animate(px) {
$('#Button1').animate({
'marginLeft': px
}, function(){
$('#Button1').animate({
'marginLeft': 1
});
});
}

Do execly the same only to the right, Its not that hard if you can make it go left.

Maybe
var button_init_marginLeft;
$(document).ready(function () {
button_init_marginLeft = $('#Button1').css("marginLeft");
example_animate(10, true);
example_animate(null, false);
});
function example_animate(px, to_left) {
if (to_left)
{
$('#Button1').animate({
'marginLeft': px
});
}
else
{
$('#Button1').animate({
'marginLeft': button_init_marginLeft
});
}
}

Hover to move slider left and right

$('#next').hover(function () {
$('#sliderWrapper').animate({
scrollLeft: "+=200px"
}, "fast");
});
$('#prev').hover(function () {
$('#sliderWrapper').animate({
scrollLeft: "-=200px"
}, "fast");
});
See fiddle. I'm trying to get the scrolling to be continuous while hovering .hover() function isn't working properly or as I thought it would.
maybe this help you
DEMO
function loopNext(){
$('#sliderWrapper').stop().animate({scrollLeft:'+=20'}, 'fast', 'linear', loopNext);
}
function loopPrev(){
$('#sliderWrapper').stop().animate({scrollLeft:'-=20'}, 'fast', 'linear', loopPrev);
}
function stop(){
$('#sliderWrapper').stop();
}
$('#next').hover(function () {
loopNext();
},function () {
stop();
});
$('#prev').hover(function () {
loopPrev();
},function () {
stop();
});
Source: Continuous scroll on hover [performance]
Try this jsFiddle
This will, on the next hover, start animating towards the width of the containing div. When you mouse out, it will stop. On the prev hover will start animating to 0 and when you mouse out it will stop.
$('#next').hover(function () {
$('#sliderWrapper').animate({scrollLeft: $(this).siblings("#sliderWrapper").width()}, 5000);
}, function() {
$('#sliderWrapper').stop();
});
$('#prev').hover(function () {
$('#sliderWrapper').animate({scrollLeft: 0 }, 5000);
}, function() {
$('#sliderWrapper').stop();
});
I would suggest using the mouse over and out events. When the mouse goes over start animating and when the mouse goes out stop animating.

jQuery Chaining animation one after another

I am using the following functions to grow the text box and display the submit button on focus and shrink and hide the button on blur.
But the button shows and hides before the animation is complete.
I am looking to create a neat slide down and slide up animation.
$('#venue-write-review').focus(function() {
$(this).animate({ height: '96px' }, 500);
$('#submit-review').show();
});
$('#venue-write-review').blur(function() {
$(this).animate({ height: '48px' }, 500);
$('#submit-review').hide();
});
You can specify a callback to the animate function to be executed once the animation is done.
$('#venue-write-review')
.focus(function() {
$(this).animate({ height: '96px' }, 500, function () {
$('#submit-review').show();
});
})
.blur(function() {
$(this).animate({ height: '48px' }, 500, function () {
$('#submit-review').hide();
});
});
This is all you need And don't forget to use .stop()!
$('#venue-write-review').on('focus blur',function(e){
$(this).stop().animate({ height: e.type[0]=="f"?96:48 }, 500, function(){
$('#submit-review').toggle();
});
});
e.type[0]=="f" ij just to check in a Conditional Operator (?:) if the passed event's first [0] character is f (focus; else logically it's blur)
Read the jQuery docs about the methods: .on(), .toggle(), stop() .animate() callback and on the MDN website read about Conditional operator
Also in jQuery if you don't need to animate by % or some other measure, you don't need to specify 'px' cause it's default.
You can use complete callback. Check the docs (under options section):
A function to call once the animation is complete.
Like this:
$('#venue-write-review').focus(function() {
$(this).animate({
height: '96px'
},
{
duration: 500,
complete: function() {
$('#submit-review').show();
}
}
});
});
$('#venue-write-review').blur(function() {
$(this).animate({
height: '48px'
},
{
duration: 500,
complete: function() {
$('#submit-review').hide();
}
}
});
});

Most efficient way to detect collision of two divs

I'm using Jquery Collision to detect two objects overlapping each other. Here is a JSFiddle of the problem.
(apologies for including jquery collision script in HTML, couldn't find other way)
Click anywhere in the gray container to move the green div over the white div.
HTML Structure:
<div class="container">
<div class="test"></div>
<div class="menu"></div>
</div>
JS:
$(document).ready(function () {
var hit_list;
$(".container").click(function () {
$(".menu").stop().animate({
left: "+=100px"
}, 300, function () {
$(".menu").animate({
left: "0"
}, 800);
});
//Test for collision
hit_list = $(".menu").collision(".test");
if (hit_list.length != 0) {
alert("welcome Earthling!");
}
});
});
The problem with my method is that, it doesn't detect collision every time. Even though it passes over the white division fine, the alert isn't displayed everytime.
Am I going wrong anywhere in checking for collision? Is there a better/more efficient method to detect collisions during animation ?
jQuery animate has a step callback (https://api.jquery.com/animate/), it gets executed after each step of the animation.
Use it like this:
$(document).ready(function () {
var hit_list;
$(".container").click(function () {
$(".menu").stop().animate({
left: "+=100px"
}, {
duration: 300,
complete: function () {
$(".menu").animate({
left: "0"
}, 800);
},
step: function(){
//Test for collision
hit_list = $(".menu").collision(".test");
if (hit_list.length != 0) {
alert("welcome Earthling!");
}
}
});
});
});
Try this http://jsfiddle.net/aamir/y7PEp/6/
$(document).ready(function () {
var hit_list;
var hits=0;
$(".container").click(function () {
var $this = $(this);
function checkCollision() {
//Test for collision
hit_list = $(".menu").collision(".test");
if (hit_list.length != 0) {
hits++;
$(".menu").html(hits+ ' hits');
}
}
$(".menu").stop().animate({
left: "100px"
}, 300, function () {
checkCollision();
$(".menu").animate({
left: "0"
}, 800);
});
});
});

Jquery Animate - trigger function mid way through animation

Is it possible to trigger a function mid way through an animation?
The animation includes a solid block which swipes over an image from top to bottom - I would like to trigger a function at the point that the image is completely covered and remove the image from the html (mid way through the animation)
My current function is -
function animateCover() {
$('#cover').animate({ bottom: '1400px'}, 4000, function() { });
}
The image is completely covered at 800px point - can I access this property to trigger a function?
since there isn't a tick counter in jQuery, you need to "emulate" it:
function animateCover() {
var
$cover = $('#cover'),
interval = setInterval(function(){
if ($cover.is(':animated')){
if (parseInt($cover.css('bottom')) > 800){
alert('trigger');
clearInterval(interval);
}
} else {
clearInterval(interval);
}
}, 13); // 13 is the minimum possible in Javascript
$cover.animate({ bottom: '1400px'}, 4000, function() { $cover.text('done'); });
}
jsFiddle: http://jsfiddle.net/emV4p/1/
What about splitting the animation into 2.
function animateCover() {
$('#cover').animate({ bottom: '700px'}, 2000, function() {
$('#imgID').hide();
$('#cover').animate({ bottom: '1400px'}, 2000 );
});
}
Updated: Here's a perfectly working solution with minimal code-
WORKING DEMO
jQuery-
$(document).ready(function(){
setInterval(function(){
$("#image").css('background-image','none');
},2000);
$("#block").animate({
bottom:'400px'
},3000);
});

Jquery animation looping

I am trying to make this animation loop
$(".jquery_bounce").ready(function(){
$("img", this).animate({ marginLeft : '20px' } , {
duration: 200,
complete:function() {
$(this).animate({ marginLeft : '0px' } , {
duration: 200,
easing: 'easeInCubic',
});
}
});
})
});
<div class="example">
<h4>Bounce</h4>
<div class="jquery_bounce bounce">
<img src="images/bounceimg.png" class="bounceimg" />
</div>
</div>
Please help.
try this~
$(function(){
$.extend({
show:function(){
$(".jquery_bounce").ready(function(){
$("img", this).animate({ marginLeft : '20px' } , {
duration: 200,
complete:function() {
$(this).animate({ marginLeft : '0px' } , {
specialEasing: {
left: 'swing',
top: 'easeOutBounce'
}
});
}
});
})
}
});
setInterval("$.show()",1000);
});
Demo:

Why don't you use setInterval()?
Edit:
Your animation bounces once, then stops, because...
You trigger the margin=20 part.
Upon completeness, another animation is scheduled: margin=0.
That's it. It doesn't loop because nothing is rescheduled to happen after the first pass.
Read the documentation on setInterval(): it's a function that let's you call another function at fixed (in milliseconds) intervals.
If you still want to do it as above, you must fix the problem I pointed out. Try thinking your way around it, and I'll help if you can't figure it out :).
Cheers.
Setup a bounce function that will continue the animation, either moving the element left or right:
function bounce(elm, leftZero) {
var px = leftZero ? '0px' : '20px';
elm.animate({ marginLeft : px}, {
duration: 200,
complete:function(){
//Continue bouncing
setTimeout(function(){
bounce(elm, !left);
},1);
}
});
}
$(".jquery_bounce").ready(function(){
$("img", this).each(function(){
//Start bouncing
bounce($(this), false);
});
})
});
