[英]Passing props to child component with react-router v6
我将 React Router v6 与单个配置文件中的所有路由一起使用,因此,使用<Outlet />
来渲染子节点。 但是,当我的路由位于单独的配置文件中时,我不知道如何根据匹配的组件传递适当的道具。
// route.ts
export const routes = [
{
path: '/*',
element: <Parent />,
children: [
{
path: 'child1',
elements: <Child1 />, // Typescript complains: Property 'firstName' is missing in type '{}' but required in type 'IProps'
},
{
path: 'child2',
elements: <Child2 />, // Property 'lastName' is missing in type '{}' but required in type 'IProps'
}
]
}
]
// App.ts
const App = () => {
const _routes = useRoutes(routes)
return _routes
}
// Parent.ts
const Parent = () => {
const firstName = 'John'
const lastName = 'Doe'
return (
<h1>Parent Component</h1>
<Outlet /> // How to pass the appropriate props?
)
}
interface IFirstNameProps {
firstName: string
}
interface ILastNameProps {
lastName: string
}
export const Child1 = (props: IProps) => {
return (
<h2>First Name</h2>
{props.firstName}
)
}
export const Child2 = (props: IProps) => {
return (
<h2>Last Name</h2>
{props.lastName}
)
}
使用<Route>
组件它会是这样的:
const Parent = () => {
const firstName = 'John'
const lastName = 'Doe'
return (
<Route path='child1' element={
<Child1 firstName={firstName} />
} />
<Route path='child2' element={
<Child2 lastName={lastName} />
} />
)
}
如何使用routes.ts
配置文件和<Outlet />
实现相同的目的?
处理这种情况的最佳方法是使用outlet context
。
在parent
组件中通过Outlet
传递上下文。
// parent.ts
const Parent = () => {
const firstName = 'John'
const lastName = 'Doe'
return (
<h1>Parent Component</h1>
<Outlet context=[firstName, lastName]/> // How to pass the appropriate props?
)
}
然后,在children
组件中,使用useOutletContext
钩子获取这些上下文数据。
import { useOutletContext } from "react-router-dom";
export const Child1 = () => {
const [firstName] = useOutletContext();
return (
<h2>First Name</h2>
{props.firstName}
)
}
export const Child2 = () => {
const [lastName] = useOutletContext();
return (
<h2>Last Name</h2>
{props.lastName}
)
}
