Props:
name- string,用于自动生成 CSS 过渡类名。例如:name: 'fade'将自动拓展为.fade-enter,.fade-enter-active等。默认类名为"v"appear- boolean,是否在初始渲染时使用过渡。默认为false。css- boolean,是否使用 CSS 过渡类。默认为true。如果设置为false,将只通过组件事件触发注册的 JavaScript 钩子。type- string,指定过渡事件类型,侦听过渡何时结束。有效值为"transition"和"animation"。默认 Vue.js 将自动检测出持续时间长的为过渡事件类型。mode- string,控制离开/进入过渡的时间序列。有效的模式有"out-in"和"in-out";默认同时进行。duration- number | {enter: number,leave: number } 指定过渡的持续时间。默认情况下,Vue 会等待过渡所在根元素的第一个transitionend或animationend事件。enter-class- stringleave-class- stringappear-class- stringenter-to-class- stringleave-to-class- stringappear-to-class- stringenter-active-class- stringleave-active-class- stringappear-active-class- string

<transition> 元素作为单个元素/组件的过渡效果。<transition> 只会把过渡效果应用到其包裹的内容上,而不会额外渲染 DOM 元素,也不会出现在可被检查的组件层级中。
