CSS transition property on page exit

阅读更多关于 CSS transition property on page exit

问题 I need a few objects on my pages to animate out when a user clicks a link. I want each object to scale and fade out but not all objects such as the navigation buttons. I was thinking that upon a user clicking a link, the page delays 1 second before opening the redirecting the link to allow fade out giving the animation time to take effect. 回答1: Look at the JS event window.onbeforeunload https://developer.mozilla.org/en-US/docs/Web/API/window.onbeforeunload It will hopefully be enough to just

本文介绍react相关的过渡动画效果的实现有点类似vue的transition组件，主要用于组件mount和unmount之前切换时应用动画效果安装 cnpm install react-transition-group --save transition动画 import React from 'react' import ReactDOM from 'react-dom' import Transition from 'react-transition-group/Transition'; const duration = 300; const defaultStyle = { transition: `opacity ${duration}ms ease-in-out`, opacity: 0, width: "100px", height: "100px", background: "red" } const transitionStyles = { entering: { opacity: 0 }, entered: { opacity: 1 }, }; class MyComponent extends React.Component { constructor() { super(); this.state = { in: false } }

Vue深度学习（5）-过渡效果

阅读更多关于 Vue深度学习（5）-过渡效果

简介通过 Vue.js 的过渡系统，你可以轻松的为 DOM 节点被插入/移除的过程添加过渡动画效果。Vue 将会在适当的时机添加/移除 CSS 类名来触发 CSS3 过渡/动画效果，你也可以提供相应的 JavaScript 钩子函数在过渡过程中执行自定义的 DOM 操作。　　以 v-transition="my-transition 这个指令为例，当带有这个指令的 DOM 节点被插入或移除时，Vue 将会：　　1.用 my-transition 这个 ID 去查找是否有注册过的 JavaScript 钩子对象。这个对象可以是由 Vue.transition(id, hooks) 全局注册，或是通过 transitions 选项定义在当前的组件内部。如果找到此对象，则会在过渡动画不同的阶段调用相应的钩子。　　2.自动探测目标元素是否应用了 CSS 过渡效果或者动画效果，并在适当的时机添加/移除 CSS 类名。　　3.如果没有提供 JavaScript 钩子函数，也没有检测到相应的 CSS 过渡/动画效果， DOM 的插入/移除会在下一帧立即执行。 <div v-if="show" transition="my-transition"></div> 所有的 Vue.js 过渡效果只有在该 DOM 操作是通过 Vue.js 触发时才会生效。触发的方式可以是通过内置指令，比如 v

总结一下目前在用的前端代码规范，可作为开发参考一、基础规范开发规范项目目录和文件的命名使用小写字母，避免使用大写或驼峰，多个单词以下划线 _ 分隔如：my_project/cast_detail.js 目录有复数意义的时候，使用复数命名如 scripts images 某些第三方插件可直接使用中划线 - 作为文件名单词的间隔如 bootstrap-datepicker 某些特殊文件可以使用点号 . 作为文件名单词的间隔如 webpack.config.dev.js jquery.cookie.min.js 使用有意义的英文单词式命名，避免使用拼音式（如 tupian.png ）命名编辑器设置文件保存格式为 utf-8，以四个空格作为缩进（包括HTML，CSS，JS等），文件末尾空一行，行尾去掉空格单个函数行数，以不超过一个屏幕为宜（50行左右），超出一个屏幕的，就要考虑拆分成更少的函数每行代码量不要太长，要适当进行分行（自己也可以在编辑器设置超长自动换行）在 sublime 中的配置 { "default_encoding": "UTF-8", "ensure_newline_at_eof_on_save": true, "trim_trailing_white_space_on_save": true, "tab_size": 4, "translate

Can d3's transition and rotation play well together?

阅读更多关于 Can d3's transition and rotation play well together?

问题 Transitions in combination with rotations have odd results. Here is a fiddle with my problem: http://jsfiddle.net/emperorz/E3G3z/1/ Try clicking on each square to see the varying behaviour. Please forgive the hacked code, but if I use transition with rotation (and x/y placement) then it loops about. I have tried: 1) all in the transform (rotate then translate), and that seems mostly okay. A little wobbly. 2) just rotate in the transform, positioned using x/y attributes. Flies all over the
