I have the following function set to run on a hover over an image:
function() {
$('.slides .slide h3').each(function(i){
var owidth = $(this).width()
$(this).animate({"right":730 - owidth - 16}, 500);
});
}
You can view the page here. Over the image and click the next icon on the lower right of the image. For some reason, the function is calculating the first h3's width correctly, but then it thinks all other h3s have a width of 0. Can anyone offer a solution?
function() {
var owidth = 0;
$('.slides .slide h3').each(function(i){
owidth = $(this).width();
$(this).animate({"right":(730 - owidth - 16) + 'px'}, 500);
});
}
A better way:
function() {
$('.slides .slide h3').each(function(i){
$(this).stop().animate({
"right": (714 - $(this).width()) + 'px'
}, 500);
});
}

I have 2 containers whose widths change. Inside them, I have clickable elements. When a container is clicked, it resizes in an animation. I want to make it so that when a clickable element is clicked, its container resizes and scrolls to the clicked element. Here's a fiddle that shows this: http://jsfiddle.net/w7H3M/1/
However, it scrolls to the wrong position because of the resizing. Here's the event handler for the click:
<div id=left>...</div>
<div id=right>...</div>
$('#left').on('click', 'a', function () {
var node = $(this);
$('#left').animate({
width: 0.75 * $(document).width()
}, 800);
$('#right').animate({
width: 0.25 * $(document).width()
}, 800);
$('body').animate({
scrollTop: node.offset().top
}, 800);
});
$('#right').on('click', 'a', function () {
var node = $(this);
$('#left').animate({
width: 0.25 * $(document).width()
}, 800);
$('#right').animate({
width: 0.75 * $(document).width()
}, 800);
$('body').animate({
scrollTop: node.offset().top
}, 800);
});
Effectively, it does not work correctly because of the animation. The offset of the node you want to show at the top of the screen will change when the div expands. To achieve what you want, you need to set the scrollTop property when the animation completes. You can achieve this using the complete handler of jQuery.animate(). I've forked your jsfiddle to show you it. The only problem is that the two animationw now play one after the other instead of simultaneously.
$(document).ready(function () {
// generate content
var str = '';
for (i = 1; i < 100; i++) {
str += '<p>' + x100(i) + '</p>';
}
$('#left').html(str);
$('#right').html(str);
// end generate content
$('#left').on('click', 'p', function () {
var node = $(this);
$('#left').animate({
width: 0.75 * $(document).width(),
}, 800, 'swing', function() {
$('body, html').animate({scrollTop: node.offset().top}, 800);
});
$('#right').animate({
width: 0.25 * $(document).width()
}, 800);
});
$('#right').on('click', 'p', function () {
var node = $(this);
$('#left').animate({
width: 0.25 * $(document).width()
}, 800);
$('#right').animate({
width: 0.75 * $(document).width()
}, 800, 'swing', function() {
$('body, html').animate({scrollTop: node.offset().top}, 800);
});
});
});
I am making a simple carousel image gallery. Currently I have two images and I would like the gallery to loop back to the first image after the last and I cannot figure out how to get this functionality working plus my previous and next button have stopped working for some reason. My jq/js skills are lacking and would appreciate any help to get this working. Here is my jsfiddle of my code [1]: http://jsfiddle.net/jsavage/kGAxa/39/
$(document).ready(function () {
if (jQuery("#gallery").length) {
// declare variables
var totalImages = jQuery("#gallery > li").length,
imageWidth = jQuery("#gallery > li:first").outerWidth(true),
totalWidth = imageWidth * totalImages,
visibleImages = Math.round(jQuery("#gallery-wrapper").width() / imageWidth),
visibleWidth = visibleImages * imageWidth,
stopPosition = (visibleWidth - totalWidth);
jQuery("#gallery").width(totalWidth);
jQuery("#gallery-prev").click(function () {
if (jQuery("#gallery").position().left < 0 && !jQuery("#gallery").is(":animated")) {
jQuery("#gallery").animate({
left: "+=" + imageWidth + "px"
});
}
return false;
});
jQuery("#gallery-next").click(function () {
if (jQuery("#gallery").position().left > stopPosition && !jQuery("#gallery").is(":animated")) {
jQuery("#gallery").animate({
left: "-=" + imageWidth + "px"
});
}
return false;
});
}
});
Tested your fiddle, javascript works well, only css is missing the following attributes:
#gallery-wrapper {
position:relative;
}
#gallery {
position:absolute;
}
And the code also needs to be executed within
$(window).load();
instead of $(document).ready(); event handler to work correctly.

Trying to make simple jQuery function to create a scrollToTop button that fades in as you scroll down.
$(document).ready(function() {
var start = 300;
var duration = 200;
var scrolled;
$('.scrollUp').css('opacity', '0.0');
$(window).scroll(function(){
var opacity = (scrolled - start) / duration;
scrolled = $(window).scrollTop();
if (0 < opacity < 1) {
$('.scrollUp').css('display', 'block').css('opacity', opacity);
} else if (1 < opacity) {
$('.scrollUp').css('display', 'block').css('opacity', '1.0');
} else {
$('.scrollUp').css('display', 'none').css('opacity', '0.0');
}
});
$('.scrollUp').click(function(){
$('html, body').animate({
scrollTop: 0
}, 500);
});
});
See it in action here: http://jsfiddle.net/JamesKyle/fBvGH/
This works, tested in jsfiddle:
$(document).ready(function() {
var start = 300;
var duration = 200;
var scrolled;
$('.scrollUp').css('opacity', '0.0');
$(window).scroll(function(){
var opacity = (scrolled - start) / duration;
scrolled = $(window).scrollTop();
if (0 < opacity < 1) {
$('.scrollUp').css('display', 'block').css('opacity', opacity);
} else if (1 < opacity) {
$('.scrollUp').css('display', 'block').css('opacity', '1.0');
} else {
$('.scrollUp').css('display', 'none').css('opacity', '0.0');
}
});
$('.scrollUp').click(function(){
$('html,body').animate({
scrollTop: 0
}, 500);
});
});
Update:
And here's a working example with the opacity animation.
Looks like this guy was looking for the same equation.
Better to use some math in situation's like this:
scrolled = $(window).scrollTop();
height = $('body').height();
height = Math.ceil((scrolled / height) * 100);
height = height / 100;
Second Update
Ok, you want it to start appearing after the dark blue section. Ok, so what you need to do is exclude that portion of the top before the gradient. You can do that by making an if clause that checks if the scrollTop value has hit the top part of the light blue gradient; around 300px from the top of the document. Then instead of using the body height in the above equation, use the total height of the gradient section; about 210px. This value will replace the var height in the jQuery above. Let me know if you have issues implementing this. Didn't notice you're comment on the above answer.
scrollTop is not a window property, so just change you code slightly:
$(window).animate({scrollTop : 0},500);
to
$('html, body').animate({scrollTop : 0},500);
here's the updated jsfiddle: http://jsfiddle.net/fBvGH/13/
Im creating myself a drag functions just for my personal use so I can drag elements around. I'm having a problem. At the moment trying to make the drag so one you pick up the element you can drag it but once you drop it, it goes back to the original position. This is not working as you can see here. When I let go of #drag2 or #drag3 then it goes to the position of #drag1.
My Function:
function drag(el) {
var position = $(el).position();
var ptop = position.top;
var pleft = position.left;
var down = false;
$(el).mousedown(function(event) {
down = true;
$(this).css({
cursor: 'crosshair',
});
$(this).mousemove(function(event) {
if (down == true) {
$(this).css({
cursor: 'crosshair',
});
var w = $(this).width();
var h = $(this).height();
var left3 = (w / 2) + 7;
var top3 = (h / 2) + 7;
$(this).css({
cursor: 'crosshair',
left: (event.clientX) + (3 * 3) - left3,
top: (event.clientY) + (3 * 3) - top3
});
}
}).mouseup(function() {
down = false;
$(this).css({
cursor: 'default',
});
$(this).animate({
top: ptop,
left: pleft
}, 300);
});
});
}
I have to get the old position:
var position = $(el).position();
var ptop = position.top;
var pleft = position.left;
So should it not get the position of all of them and bring them self back to where they were? Any help will be appreciated.
EDIT: I DO NOT WANT TO USE ANY PLUGIN OR JQUERY UI, THANKS ANYWAYS
The solution is very simple
See this fiddle: http://jsfiddle.net/BggPn/4/
you define 1 var for left and 1 for top. All 3 the elements use the same variables. If you loop through the elements then you make a new scope where each element has it's own vars.
Working code:
$(document).ready(function() {
drag('#drag, #drag2, #drag3')
});
function drag(el) {
$(el).each(function(){
var position = $(this).position();
var ptop = position.top;
var pleft = position.left;
var down = false;
$(this).mousedown(function(event) {
down = true;
$(this).css({
cursor: 'crosshair',
});
$(this).mousemove(function(event) {
if (down == true) {
$(this).css({
cursor: 'crosshair',
});
var w = $(this).width();
var h = $(this).height();
var left3 = (w / 2) + 7;
var top3 = (h / 2) + 7;
$(this).css({
cursor: 'crosshair',
left: (event.clientX) + (3 * 3) - left3,
top: (event.clientY) + (3 * 3) - top3
});
}
}).mouseup(function() {
down = false;
$(this).css({
cursor: 'default',
});
$(this).animate({
top: ptop,
left: pleft
}, 300);
});
});
});
}
Make it a plugin:
$.fn.drag = function drag(){
return this.each(function(){
var position = $(this).position();
var ptop = position.top;
var pleft = position.left;
var down = false;
$(this).mousedown(function(event) {
down = true;
$(this).css({
cursor: 'crosshair',
});
$(this).mousemove(function(event) {
if (down == true) {
$(this).css({
cursor: 'crosshair',
});
var w = $(this).width();
var h = $(this).height();
var left3 = (w / 2) + 7;
var top3 = (h / 2) + 7;
$(this).css({
cursor: 'crosshair',
left: (event.clientX) + (3 * 3) - left3,
top: (event.clientY) + (3 * 3) - top3
});
}
}).mouseup(function() {
down = false;
$(this).css({
cursor: 'default',
});
$(this).animate({
top: ptop,
left: pleft
}, 300);
});
});
});
}
Now you can call it by:
$("#drag1, #drag2").drag();
2 thoughts:
1.) Why don't you use jQuery UI (draggable)?
2.) The idea of giving a selector in stead of an element is wrong, a selector can lead to multiple elements, and that's the first reason why it's failing. If you start with
function drag(selector) {
$(selector).each(function() {
var el = $(this);
//rest of code
}
}
it would be better. But I think you'll run into a few other problems eventually
The problem is whenever you're sending in the list of selectors '#drag, #drag2. #drag3' and your position variable only cares about the first one (try changing the order and you'll see they snap to the first in the list). If you want to go about it this way then you'll want to perform an each iteration over them to get the right values.
get the current position of div after drag and set via this
.mouseup(function() {
var position = $(this).position();
down = false;
$(this).css({
cursor: 'default',
});
$(this).animate({
top: position.top,
left: position.left
}, 300);
DEMO
why don't you use drag and drop plugin. see this article
http://viralpatel.net/blogs/2009/05/implement-drag-and-drop-example-jquery-javascript-html.html
or this one

ok so i have an interspire shopping cart so its hard to customize..
anyway,
here is a link to my code
http://jsfiddle.net/WTvQX/
im having trouble getting the scroll to work properly...
it works differently on my actual site here...
so i need help... re-doing it or just fixing..
let me kno
You need to add the "relatedLeft" ID to the left button, however try something like this...
Demo: http://jsfiddle.net/wdm954/WTvQX/3/
$('#relatedRight').click(function() {
$('#scool').animate({left: "+=100px"}, 'slow');
});
$('#relatedLeft').click(function() {
$('#scool').animate({left: "-=100px"}, 'slow');
});
You can adjust pixel distance and speed to your liking.
EDIT: Try something like this. The first part finds the width of all the images. Then the animates only fire when the offset is within range.
Demo: http://jsfiddle.net/wdm954/WTvQX/5/
var w = 0;
$('#scroll img').each(function (i, val) {
w += $(this).width();
});
$('#relatedRight').click(function() {
var offset = $('#scroll').offset();
if (offset.left < w) {
$('#scroll').animate({left: "+=100px"}, 'slow');
}
});
$('#relatedLeft').click(function() {
var offset = $('#scroll').offset();
if (offset.left > -w) {
$('#scroll').animate({left: "-=100px"}, 'slow');
}
});
EDIT: One more code option here. This one will stop scrolling sooner (note there are CSS changes here also).
Demo: http://jsfiddle.net/wdm954/WTvQX/7/
var w = 0;
$('#scroll img').each(function (i, val) {
w += $(this).width();
w += parseFloat($(this).css('paddingRight'));
w += parseFloat($(this).css('paddingLeft'));
w += parseFloat($(this).css('marginRight'));
w += parseFloat($(this).css('marginLeft'));
});
$('#scroll').css('width', w + 'px');
$('#relatedRight').click(function() {
var offset = $('#scroll').offset();
if (offset.left < 0) {
$('#scroll').stop().animate({left: "+=100px"}, 'slow');
}
});
$('#relatedLeft').click(function() {
var offset = $('#scroll').offset();
var b = $('#bar').width();
if (offset.left > b-w) {
$('#scroll').stop().animate({left: "-=100px"}, 'slow');
}
});
