问题 Something this simple should be easily accomplished, yet I'm pulling my hair out over how complicated it is. All I want to do is animate the mounting & unmounting of a React component, that's it. Here's what I've tried so far and why each solution won't work: ReactCSSTransitionGroup - I'm not using CSS classes at all, it's all JS styles, so this won't work. ReactTransitionGroup - This lower level API is great, but it requires you to use a callback when the animation is complete, so just using

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

问题 Using the TweenMax library, I am unable to kill or stop a delayedCall when the end of the data object is reached instead of looping because it is a self calling function. https://jsfiddle.net/rdzo13cf/6/ In the example above the last item in the data is not displayed. 回答1: Actually it's because you are incrementing your iter variable before you set it. Which causes it to not display the last item, you want to increment after: function setContent() { element.html(data[iter].content); iter =

问题 I am really new with GSAP and I think it is amazing. However I cannot work out how to fade in these items separately. 1st one (this is fine) for the 2nd wish to fade in at a certain time and 3rd at a certain time. JavaScript: function startFinalAnimation(){ var fa = new TimelineLite(); fa.to(finalAvatar, 2, {scale: 0.45, delay: 0, opacity: 1, transformOrigin:"-3% 8.8%"}); fa.to(finalContent, 4, {delay: 0, opacity: 1}); fa.to(logo, 5, {delay: 0, opacity: 1}); } 回答1: TimelineLite 's .to()

问题 I am trying to animate a line using canvas. I want to use TimelineLite to handle the animation. How would I do this? I know that in TimelineLite, the Timelines look like this: var timeline = new TimelineLite(); timeline.to(target, duration, vars, position); The points exist in a JSON file, and the file is correctly being brought in with AJAX. I want the line to start at the points x1 & y1, keep x2, as the same value, and animate it to the y2 position. So I basically want it to grow from x1-y1

问题 as of version 4.5.1 the old Transition class has been retired and "KineticJS recommends the GreenSock Animation Platform which integrates seamlessly". I am writing a canvas game using KineticJS which relied quite heavily on that old Transition class but having read up on GSAP's abilities I'm quite keen to upgrade. My problem is that when I try using even the simplest TweenLite functions they are completely ignored by my canvas. I'm guessing I must be missing something obvious because I haven

问题 I'm not able to get TweeLite to work with browserify. I'm an extreme noob when it comes to CommonJS. I've installed gasp v1.13.2 using Bower and include it like this: var TweenLite = require("../../bower_components/gsap/src/minified/TweenLite.min.js"); I don't get any errors when using it, but my animations don't work. According to gsap docs this version should work without a shim. What am I doing wrong? Can anyone provide a working example? https://greensock.com/gsap-1-13-1 I've just started

问题 What I want to do is this: I want to generate boxes on the Y or X axis of the page (the bottom and left border) and make them move parallel to each other until they've gone off-screen, where I want to delete them. This is what I've done so far: Codepen . function generate(){ var $element = $("<div>", {class: "box"}); //Generate random x and y coordinates var posy = (Math.random() * ($('body').height() - $element.width())).toFixed(); var posx = (Math.random() * ($('body').width() - $element

问题 Holla, I need to reset the animation when I close menu and open it again. How can I do that? Animation works only the first time when I open menu. CSSPlugin.defaultTransformPerspective = 600; TweenMax.staggerFrom('ul#menu li', 1.5, {rotationX:-90, transformOrigin:"50% 0%", ease:Elastic.easeOut}, 0.4); Here is the code: http://codepen.io/hafsadanguir/pen/qOdaab. Thanks for help! 回答1: Is this the kind of result you were after? JavaScript: CSSPlugin.defaultTransformPerspective = 600; var

问题 How would I go about adjusting the time manually based on the scroll position? What might that look like? To basically 'scroll' the tween? So that the tween reacts to the scrolling mouse's Y position rather than just trigger and execute based on a preset time? 回答1: While Tahir's answer is correct and sufficient, there's a lot of unnecessary code to show the example. A more concise snippet is: var max_scroll = document.body.offsetHeight - window.innerHeight; win.addEventListener('scroll',
