React项目动态设置title标题

在React搭建的SPA项目中页面的title是直接写在入口index.html中,当路由在切换不用页面时,title是不会动态变化的。那么怎么让title随着路由的切换动态变化呢?
1.在定义路由时增加title属性。


    {
        path: "/regularinvestment",
        component: Loadable({
            loader: () => import('./../../business/Regularinvestment/index'),
            loading: PageLoading
        }),
        title: "这是自定义的标题"
    }

2.在路由的index.js获取到自定义的title设置页面标题即可。


   const RouteWithSubRoutes = route => {
        return (
            <Route
                exact
                path={route.path}
                render={props => {
                    document.title = route.title || "默认title";
                    return <route.component {...props} routes={route.routes}></route.component>
                }}
            />
        );
    };
    
    export default () => {
        return allRouters.map((route, i) => {
            return <RouteWithSubRoutes key={i} {...route}/>
        })
    };
