由 时光总嘲笑我的痴心妄想 提交于 2019-12-31 05:13:57
问题 The question is in in transitionBackground function. In this case, the function triggers when the up button is pressed on the page. <html> <head> <title>Case: Background Transitions</title> <script src="jquery/jquery.js"></script> <script> $( var transitionBackground = function (){ if ($(div).css("background") === "blue"){ //convert to green by having the green background start at the bottom, //and slide up (over say, a period of 1 second) //I'll up vote a pure-css, pure-js, or a jquery

iPad / jQuery.animate(scroll) issues

由 老子叫甜甜 提交于 2019-12-30 11:27:07
问题 I have a page that uses jQuery.animate to scroll the body/html of the document, it works fine in browsers but just won't play ball with iPad. First it is supposed to scroll in the Y direction then X, but on an iPad it scrolls in the Y, then it jumps back to the original position before scrolling in the X direction. After the animations are complete the links that are used to navigate cease to function unless you manually scroll the page, then they will work again! What am I doing wrong here?

问题 I have an object (image) in the center of the screen. Now I want to animate some circles around this object. What is the best idea to realize that task? Should I use any dedicated JS library for animation? 回答1: CSS will give smoothness take a look at this link It is better to use CSS3 instead of JavaScript because the resultant animation is always guaranteed to be smoother (especially on mobile devices) plus it can save on battery power. 回答2: You can use some simple trigonometry such as this:

jQuery Animate not working on background-color property

由 删除回忆录丶 提交于 2019-12-29 08:55:11
问题 I was playing around with the jQuery .animate() function, and ended up trying to change the background-color of one of the div s depending on the number of pixels scrolled by the user.

The jsFiddle link : https://jsfiddle.net/ag_dhruv/cb2sypmu/ 回答1: As per jQuery API docs: The .animate() method allows

How do I rotate or scale (transform) an SVG path relative to its center point?

由 五迷三道 提交于 2019-12-29 08:50:50
问题 I'm trying to rotate and scale shapes within an SVG around their center point. I've looked into several libraries, including Jquery, Greensock, D3, RaphaelJS, but I haven't been able to find any that provide a straightforward way to accomplish this. Each animates the shape from the origin point (which I understand is the default). I want to be able to spin a shape around its center point or scale it up or down from the center point. Here are a couple examples using Greensock and D3 that

Image resizing with Jquery Animate

由 你说的曾经没有我的故事 提交于 2019-12-29 07:06:10
问题 Is it possible to have a picture animate from the center outwards rather than from left to right (and top to bottom)? The effect I'm trying to achieve is similar to lightbox, when you click on an image and it expands outwards. Thanks! 回答1: @Aron's solution is ok, but it comes with certain limitations: you can't have an image within the document flow. My solution actually creates an absolutely positioned clone of the image and shows it on top of the original image. It calculates the original

jQuery animate a -webkit-transform

由 我怕爱的太早我们不能终老 提交于 2019-12-29 06:19:09
问题 Is it possible to use jQuery to animate a webkit translate3d? I read that when using the animate property of jQuery that you must camel case the css properties but in the case of the translate3d this doesn't seem to work.

jQuery: Animate Margins to Auto?

由 僤鯓⒐⒋嵵緔 提交于 2019-12-29 06:18:33
问题 I'm trying to animate an image so that it centers itself. Here's the code I'd like to use: $('#myImage').animate({'margin-right': 'auto'}); But when I do that, it's ignored and doesn't change the margin. Is there a way to animate a margin to auto, or otherwise center an image? Thanks! 回答1: As 'auto' isn't a number, jQuery cannot animate it. If you are okay with taking the image out of the flow of the document, you can set position to absolute or fixed and try: $('#myImage').animate({'left':
