At the initial mount, all children of the ReactCSSTransitionGroup will appear but not enter. However, all children later added to an existing ReactCSSTransitionGroup will enter but not appear. componentWillAppear和 componentDidAppear这两个钩子函数,只能在ReactTransitionGroup初始化的时候,被在刚开始就存在于ReactTransitionGroup中的子元素所触发,并且只能触发一次,后来追加进来的子元素只会触发 componentWillEnter 和 componentDidEnter,而不会触发 Enter。
transitionAppear:初次mount的时候的动画 默认是不打开的 使用方式: transitionAppear={true} transitionAppearTimeout={500}
transitionEnter:除了初次mount之外,其他都是enter
