React Router提供了嵌套式的路由声明方案来表述组件之间的从属关系,嵌套式的路由就好像树形结构一样,而React Router来对某个URL进行匹配的时候也会按照深度优先的搜索方案进行匹配搜索。 Path Syntax:路径表达式 一个典型的路由路径由以下几个部分组成: :paramName– 匹配参数直到/,?, or#. ()– 匹配可选的路径 *...
1、component: 当传递component渲染UI时,router将会用React.createElement来将组件封装成一个新的React element, 当传递一个inline func, react每次render都会unmount, mount一个新的组件,会消耗性能,此时可以使用render/children prop 2、render: func, inline func不会有上述性能问题,参数同route props相同。 3、childr...
