I've got this code
var goRight = function() {
$(this).animate({'left:' '40px'}, 1000, goLeft);
};
var goLeft = function() {
$(this).animate({'left:' '-40px'}, 1000, goRight);
};
var main = function() {
$('.square').hover(function() {
$(this).toggleClass('active');
});
$('.square').goRight();
};
$(document).ready(main);
It supposed to move the square(a div) to the right then back to the left infinitely and make it blue when the user hovers over it. But it doesn't work. The problem is probably in the goRight and goLeft, functions. Since if I remove them completely the hover changes the color fine. And when these functions are there nothing works.
You need to do the chaining like this
$.fn.goRight = function() {
this.animate({
'left': '40px'
}, 1000, function() {
$(this).goLeft()
});
return this;
};
$.fn.goLeft = function() {
this.animate({
'left': '-40px'
}, 1000, function() {
$(this).goRight()
});
return this;
};
var main = function() {
$('.square').hover(function() {
$(this).toggleClass('active');
});
$('.square').goRight();
};
$(document).ready(main);

I am using popup plugin presented by some user of stackoverflow.
It works perfectly, but I wanted to add another one on the same page and it does some strange things. The first one works fine, the second one opens, but when i want to close it, it opens the first one instead. Could someone give me any clue please? I have changed all the classes, IDs etc
First one:
...
<a href='/contact' class='menuButton' id='contact'>KONTAKT</a>
<div class="messagepop pop">
<p>popup message1</p>
</div>
...
<script>
function deselect(e) {
$('.pop').slideFadeToggle(function() {
e.removeClass('selected');
});
}
$(function() {
$('#contact').on('click', function() {
if($(this).hasClass('selected')) {
deselect($(this));
} else {
$(this).addClass('selected');
$('.pop').slideFadeToggle();
}
return false;
});
$('.close').on('click', function() {
deselect($('#contact'));
return false;
});
});
$.fn.slideFadeToggle = function(easing, callback) {
return this.animate({ opacity: 'toggle', height: 'toggle' }, 'fast', easing, callback);
};
</script>
Secone one:
...
<a href='/contact2' class='menuButton' id='contact2'>BILETY</a>
<div class='messagepop2 pop2'>
<p>popup message 2</p>
</div>
...
<script>
function deselect(e) {
$('.pop2').slideFadeToggle(function() {
e.removeClass('selected2');
});
}
$(function() {
$('#menuButtonBilety').on('click', function() {
if($(this).hasClass('selected2')) {
deselect($(this));
} else {
$(this).addClass('selected2');
$('.pop2').slideFadeToggle();
}
return false;
});
$('.close2').on('click', function() {
deselect($('#menuButtonBilety'));
return false;
});
});
$.fn.slideFadeToggle = function(easing, callback) {
return this.animate({ opacity: 'toggle', height: 'toggle' }, 'fast', easing, callback);
};
</script>
EDIT: The script comes from the best answer HERE
In your case probably you are overriding the deselect function.
But instead of multiply your code one for each element instance you can set it more general using DOM structure hierarchy, like:
function deselect(e) {
e.next('.pop').slideFadeToggle(function () {
e.removeClass('selected');
});
}
$(function () {
$('.menuButton').on('click', function () {
if ($(this).hasClass('selected')) {
deselect($(this));
} else {
$(this).addClass('selected');
$(this).next('.pop').slideFadeToggle();
}
return false;
});
});
$.fn.slideFadeToggle = function (easing, callback) {
return this.animate({
opacity: 'toggle',
height: 'toggle'
}, 'fast', easing, callback);
};

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);
});
});
});
I have an animation that causes boxes to appear in sequence when clicking a link. I'm finding that the animation does not stop when clicking a new link and will often cause the it to appear out of sequence. You can see this here when clicking between guests rapidly. I thought something like $.animation.stop() would solve the issue but it hasn't. Any help would be appreciated.
var stepFade = function() {
if ($($this).data("known1") === undefined || null) {
$('.guest-data .known-for').css('display', 'none');
} else {
$('.guest-data .known-for').css('display', 'block');
$('.guest-data .known-for li').eq(0).delay(200).fadeIn( 300);
$('.guest-data .known-for li').eq(1).delay(300).fadeIn( 300);
$('.guest-data .known-for li').eq(2).delay(400).fadeIn( 300, function() { animating = false; });
}
}
//Fade guest
if (!featured) {
featured = true;
getData();
$('.featured').fadeOut( 500, function () {
$('.selected').animate({ opacity: 'toggle'}, 500, function() {
stepFade();
});
})
} else {
$('.selected, .guest-data .known-for, .guest-data .known-for li').fadeOut( 500, function () {
getData();
$('.selected').fadeIn( 500, function() {
stepFade();
});
});
}
Have you tried setting the queue option of .animate() to false?
This way, the animation won't be queued and will begin immediately:
$('.selected')
.animate({opacity: 'toggle'},
{duration: 500, queue: false,
complete: function() { stepFade(); }
});
...OR you could call .stop() right before you call .animate():
$('.selected')
.stop(true, false) //clear the queue and don't jump to the end
.animate({opacity: 'toggle'}, 500, function() {
stepFade();
});
Why will this code not work as an onclick ?
$('.mainz11').click (function() {
$(this).animate({
height: '280px'
}, 800);
}, function() {
$(this).animate({
height: '100px'
}, 800);
});
If you're trying to first expand the element and then contract it, it should probably be something like this:
$('.mainz11').click(function() {
// determine target heights
if ($(this).hasClass("expanded")) {
var targetHeight = 100;
} else {
var targetHeight = 280;
}
// animate
$(this).animate({
height: targetHeight
}, {
duration: 800,
complete: function() { $(this).toggleClass("expanded"); }
});
});
This could use some cleaning up, but it does the trick, and you can track expanded items easily this way.
See here: http://jsfiddle.net/mpQek/3/
The click function takes only a single function but you are passing 2 functions to it. You can try it this way:
$('.mainz11').click (function() {
$(this).animate({
height: '280px'
}, 800);
});
If you want to chain animations, put the next animation as the function to run on complete of the first animation:
http://api.jquery.com/animate/
$('.mainz11').click (function() {
$(this).animate({ height: '280px', 800,
function() { $('.mainz11').animate({ height: '100px'}, 800)
);
});
I'm trying to implement the scrollTo script jquery script from http://flesler.blogspot.com/2007/10/jqueryscrollto.html but I cant figure it out because of the way my script is setup:
$(".viewproject").click(function() {
$(...).scrollTo( '#lightwrap', 2500, {easing:'elasout'} );
var id = $(this).attr("id").replace(/^.(\s+)?/, "");
var contentTobeLoaded = $("#workitem" + id).html();
$('#projectajax').animate({
opacity: '0'
}, 600, function() {
$('#projectpanel').show();
if ($('#projectajax').is(':visible')) {
$('#projectajax').html(contentTobeLoaded).delay(500).animate({
opacity: '1'
}, 500, function() {
$('#thumbnails, h3').css('border-top', '1px solid #fff');
});
}
else {
$('#projectajax').html(contentTobeLoaded).hide().slideDown(1000).delay(500).animate({
opacity: '1'
}, 500, function() {});
}
});
});
$(document).on('click', '#projectclose', function(e) {
e.preventDefault();
$("#projectpanel").slideUp('1000');
});
or http://jsfiddle.net/Rvgk9/
what im trying to do is when the image or link is clicked, i want it to scroll to the top of the website before if #projectajax is visible and also if #projectajax isnt visible.. from what I've tried it just didnt have the scrolling effect at all just snapped to the top of the page.
