fs-css-transition v1.1.4

fs-css-transition

解决react-transition-group CSSTransition无法同时定制多个css动画的问题

基础示例

基础用法与CSSTransition一致

import React, { Component } from 'react'
import FsCSSTransition from '../../src/index'

import './index.css'

class BaseDemo extends Component {
  state = {
    show: true
  }

  toggleShow = () => {
    this.setState({
      show: !this.state.show
    })
  }

  render() {
    return (
      <div>
        <button onClick={this.toggleShow}>click</button>
        <FsCSSTransition in={this.state.show} timeout={300} classNames="fade">
          <div className="box">base demo</div>
        </FsCSSTransition>
      </div>
    )
  }
}

export default BaseDemo

classNames可以为string也可以为object,同CSSTransition一致

同时控制多个动画

与CSSTransition不同的是，如果children为function，FsCSSTransition会将相应的类名回传回来，我们可以通过这样的方式来同时控制多个css动画

import React, { Component } from 'react'
import FsCSSTransition from '../../src/index'
import classnames from 'classnames'
import './index.css'

class InverseOfControl extends Component {
  state = {
    show: true
  }

  toggleShow = () => {
    this.setState({
      show: !this.state.show
    })
  }

  render() {
    return (
      <div>
        <button onClick={this.toggleShow}>click</button>
        <FsCSSTransition in={this.state.show} timeout={3000} classNames="ioc">
          {(state, className) => {
            return (
              <div>
                <div className={classnames('ioc-box1', className)} />
                <div className={classnames('ioc-box2', className)} />
              </div>
            )
          }}
        </FsCSSTransition>
      </div>
    )
  }
}

export default InverseOfControl

相应的样式为

.ioc-box1 {
  width: 100px;
  height: 100px;
  background: #59c;
}
.ioc-box1.ioc-enter {
  opacity: 0;
}
.ioc-box1.ioc-enter-active {
  opacity: 1;
  transition: all 3s ease-in-out;
}
.ioc-box1.ioc-exit {
  opacity: 1;
}
.ioc-box1.ioc-exit-active {
  opacity: 0;
  transition: all 3s ease-in-out;
}

.ioc-box2 {
  position: relative;
  width: 100px;
  height: 100px;
  background: #98c;
}
.ioc-box2.ioc-enter {
  left: 3000px;
}
.ioc-box2.ioc-enter-active {
  left: 0;
  transition: left 3s ease-in-out
}
.ioc-box2.ioc-exit {
  left: 0;
}
.ioc-box2.ioc-exit-active {
  left: 3000px;
  transition: left 3s ease-in-out;
}

Props

• in: boolean, 用于控制是否显示
• timeout: number, 用于估算动画完成时间
• children: function or ReactNode, 为function，回传动画状态(exited, exiting, entered, entering)和当前的类名 (state: string, className: string): void
• classNames: object or string, 为string，会依次添加*-enter,*-enter-active,*-enter-done,*-exit, *-exit-active, *-exit-done，为object则意味着自己定制相关状态的类名,e.g { enter: 'cls-enter', enterActive: 'cls-enter-active', enterDone: 'cls-enter-done', exit: 'cls-exit', exitActive: 'cls-exit-active', exitDone: 'cls-exit-done' }
