如何在 React-Router 中传递参数

用户7545438

我将 React 与 React Router 一起使用，并且我有 3 个链接与组件具有相同的路径。如何在点击组件时传递不同的参数？

const Example = props => {
  console.log("props", props);

  return (
    <div className="App">
      <h1>Hello CodeSandbox</h1>
      <h2>Start editing to see some magic happen!</h2>
    </div>
  );
};

function App() {
  return (
    <BrowserRouter>
      <Switch>
        <Route path={"/example"} render={() => <Example />} />
      </Switch>
      <>
        <Link to={"/example"} params={{ name: "john" }}>
          <button>name</button>
        </Link>
        <Link to={"/example"} params={{ age: "27" }}>
          <button>age</button>
        </Link>
        <Link to={"/example"} params={{ surname: "Travolta" }}>
          <button>surname</button>
        </Link>
      </>
    </BrowserRouter>
  );
}

您可以使用Link的to属性，并使用访问 Example 组件中的状态props.location.state。

import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter, Switch, Route, Link } from "react-router-dom";
import "./styles.css";

const Example = props => {
  console.log("props", props.location.state);

  return (
    <div className="App">
      <h1>Hello CodeSandbox</h1>
      <h2>Start editing to see some magic happen!</h2>
    </div>
  );
};

function App() {
  return (
    <BrowserRouter>
      <Switch>
        <Route path="/example" component={Example} />
      </Switch>
      <>
        <Link to={{pathname:"/example", state: {name: "john"}}} >
          <button>name</button>
        </Link>
        <Link to={{pathname:"/example", state: {age: "27"}}} >
          <button>age</button>
        </Link>
        <Link to={{pathname:"/example", state: {surname: "Travolta"}}}  >
          <button>surname</button>
        </Link>
      </>
    </BrowserRouter>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
