React-router 不显示组件

Question

我目前正在学习 react-router，然后尝试在示例应用程序中实现它。

这是我的代码：

index.html

<!DOCTYPE html>
<html>
    <head>
        <title>Sample APP</title>
        <link rel="stylesheet" href="dist/css/style.css">
    </head>

    <body>
        <div id="main"></div>
    </body>

    <script src="dist/js/main.js"></script>
</html>

/src/app.jsx

var React = require('react');
var ReactDOM = require('react-dom');

var Routes = require('./routes');

ReactDOM.render(Routes, document.getElementById('main'));

/src/routes.jsx

var React = require('react');
var Router = require('react-router').Router;
var Route = require('react-router').Route;
var Link = require('react-router').Link;

var HelloWorld = require('./components/hello-world');
var NotFound = require('./components/not-found');
var About = require('./components/about');

module.exports = (
    <Router>
        <Route path="/" component={HelloWorld}>
            <Route path="about" component={About}/>
        </Route>
    </Router>
);

/src/components/hello-world.jsx

var React = require('react');
var Link = require('react-router').Link;

module.exports = React.createClass({
    render: function() {
        return <div>
            <h1>
                Hello World !
            </h1>
            <Link to="/about">About</Link>
        </div>
    }
});

/src/components/about.jsx

var React = require('react');

module.exports = React.createClass({
    render: function() {
        return <h1>
            About
        </h1>
    }
});

package.json

{...}
"dependencies": {
    "browserify": "^9.0.3",
    "gulp": "^3.8.11",
    "gulp-concat": "^2.5.2",
    "gulp-react": "^3.0.1",
    "gulp-sass": "^2.0.1",
    "gulp-server-livereload": "^1.3.0",
    "gulp-util": "^3.0.4",
    "gulp-watch": "^4.2.4",
    "history": "^1.13.1",
    "node-notifier": "^4.2.1",
    "react": "^0.14.3",
    "react-dom": "^0.14.3",
    "react-router": "^1.0.0",
    "reactify": "^1.1.0",
    "vinyl-source-stream": "^1.1.0",
    "watchify": "^2.4.0"
}

我使用 gulp 到 browserify 和 reactify 我的来源到 /dist/js/main.js

当我点击我的 about link 时，url 从 http://localhost:8000/#/?_k=zkmiyh 变为 http://localhost:8000/#/about?_k=6nhkao 但显示的组件仍然是 hello-world .

我的控制台上没有显示任何错误。

是不是漏了什么？

Answer 1

我的应用程序也有同样的问题我已经更改了父级并设置为相同的节点然后它正在工作可能对你有帮助

module.exports = (
<Router>
    <Route path="/" component={HelloWorld} />
    <Route path="about" component={About}/> 
</Router>

);

Answer 2

丑陋的解决方案是摆脱嵌套路由，如下所示：

module.exports = (
    <Router>
        <Route path="/" component={HelloWorld} />
        <Route path="/about" component={About} />
    </Router>
);

然而，我通过 this doc

找到了正确的方法

我们需要另一个组件（我称之为 Main），它将包含要显示的正确组件（即 this.props.children）。

我使用 IndexRoute 定义要显示的 default 组件。

这是更正后的代码：

/src/components/main.jsx (new)

var React = require('react');

module.exports = React.createClass({
    render: function() {
        return <div>
            // this is where you can add header
            {this.props.children}
            // this is where you can add footer
        </div>
    }
});

/src/routes.jsx (修改)

var React = require('react');
var Router = require('react-router').Router;
var Route = require('react-router').Route;
var IndexRoute = require('react-router').IndexRoute;

var Main = require('./components/main');
var HelloWorld = require('./components/hello-world');
var About = require('./components/about');

module.exports = (
    <Router>
        <Route path="/" component={Main}>
            <IndexRoute component={HelloWorld} />
            <Route path="about" component={About} />
        </Route>
    </Router>
);

Answer 3

module.exports = (
    <Router>

        <Route path="/"> 
           <HelloWorld/> 
        </Route>

        <Route path="about"> 
           <About/>
        </Route>

    </Router>
);

这可能有助于您检查。

在我的例子中，我忘记了我在我的 index.js 中添加了一个 BrowserRouter 组件，然后在我的 app.js 中添加了另一个组件。一旦我删除了其中一个，它就起作用了。
