Why are slow jQuery animations choppy?

只谈情不闲聊 提交于 2019-12-04 01:10:32
I'm having a hard time googling this issue because most of the things I can find are about animations that are supposed to be fast but are acting slow. My question is regarding an animation that I want to have a long duration but still be smooth. I've created this jsfiddle to demonstrate the issue: http://jsfiddle.net/93Bqx/ I'm trying to make an element slowly move to another position over time. But the animation is very choppy. Basically, it boils down to something like this: $elem.animate({ left: x, top: y }, someLargeNumber); I'm wondering if the problem is that the animation is so slow

How to transition child when parent goes from display: none to block

自闭症网瘾萝莉.ら 提交于 2019-12-04 00:19:38
I'm having trouble creating a flyout menu with a specific effect. The flyout goes from display:none to block and then I use jquery to animate opacity from 0 to 1 (and vice versa). This is necessary because otherwise the transition does not happen when the element has just had it's display property changed. I did not think that this would propagate to children. But inside of my flyout I have 4 columns of links that have an opacity transition, each with it's own delay so they come in one at a time. However, this does not work as the flyout appears. They are instantly at opacity: 1 and even with

问题 I have this code, which slides open a basket preview on a website I am working on. It stays open if the user is hovered on it, but I want it to have a two second delay before the callback for my hover is triggered. This is just in case the user didn't want the mouse to leave the basket area. Below is the code I am using to animate the basket: $('.cart_button, .cart_module').hover(function(){ $(".cart_module").stop().animate({top:'39px'},{duration:500}); }, function(){ $('.cart_module').stop()

Scrolling a jQuery animation backwards and forwards

I am making a futsal (indoor soccer) coaching application which allows a coach to add players on the screen, set their movement direction (by drawing arrows using HTML5 canvas), and then press 'play' to move all players on the screen. A player is made up of a div with a background image of a player. Animation is being done by using jquery .animate() function. All I do is change the player div's left and top css position attributes. I would like to do two things and unsure on how that can be done: I want to create a jQuery slider and move it incremently as the animation takes place. I am

jQuery multiple animate() callback

不打扰是莪最后的温柔 提交于 2019-12-03 13:57:14
I'm trying to animate a set of elements simultaneously (almost, there's a small delay between each animation): $('.block').each(function(i){ $(this).stop().delay(60 * i).animate({ 'opacity': 1 }, { duration: 250, complete: mycallbackfunction // <- this fires the callback on each animation :( }); }); How can I run a callback function after all animations have completed? Use a closure around a counter variable. var $blocks = $('.block'); var count = $blocks.length; $blocks.each(function(i){ $(this).stop().delay(60 * i).animate({ 'opacity': 1 }, { duration: 250, complete: function() { if (--count

Animating a CSS transform with jQuery

眉间皱痕 提交于 2019-12-03 13:26:55
I'm trying to animate a div, and get it to rotate about the y-axis 180 degrees. When I call the following code I get a jQuery error: $("#my_div").animate({ "transform": "rotateY(180deg)", "-webkit-transform": "rotateY(180deg)", "-moz-transform": "rotateY(180deg)" }, 500, function() { // Callback stuff here }); }); It says "Uncaught TypeError: Cannot read property 'defaultView' of undefined" and says it's in the jQuery file itself... what am I doing wrong? You can also predefine the rotation in a CSS class and use jQuery to add/remove the class: CSS: #my_div { -moz-transition: all 500ms ease;

Animate/Ease an element to position when other elements disappear

孤街浪徒 提交于 2019-12-03 13:22:34
Please take a look at this fiddle: http://jsfiddle.net/dhcyA/ Try clicking on a block. What I want is that when the other elements disapear, the selected block will animate/ease to his giving position instead of just jumping like it does now. Then the same animation repeats itself when clicking again on the box, but then back to place. Maybe to keep in mind: I'm using a reponsive design, which means those blocks can be vertical and horizontal after scaling the window. Any redevisions on the fiddle or suggustions would be great! Here is my solution. On your existing markup, I added a wrapper

问题 I have a "Menu" button on the left hand side of the page and once selected I have a div containing the menu items show. I then have another button that can be selected to hide the menu. Ideally I want this to slide out (from left to right) and back but have been unsuccessful in getting this working well. I have tried using animate and SlideToggle but none work well for what I have. Any tips? <div id="cat_icon">Menu</div> <div id="categories"> <div CLASS="panel_title">Menu</div> <div CLASS=
