目前我正在为我的应用程序使用以下代码。
const {
Router,
Route,
IndexRoute,
Redirect,
Link,
IndexLink,
hashHistory
} = ReactRouter
var App = React.createClass({
render : function() {
return (
<div>
<h1>My Application</h1>
<div><Link to="/levelone/1">Go to One</Link></div>
<div><Link to="/levelone/1/leveltwo/5">Go to Three</Link></div>
{this.props.children}
</div>
)
}
})
var Index = React.createClass({
render : function() {
return (
<div>
<h2>This is index route</h2>
</div>
)
}
})
var LevelOne = React.createClass({
render : function() {
return (
<div>
<h2>This is LevelOne</h2>
{this.props.children}
</div>
)
}
})
var LevelTwo = React.createClass({
render : function() {
return (
<div>
<h2>This is LevelTwo</h2>
</div>
)
}
})
var routes= (
<Route path= "/" component={App}>
<IndexRoute component={Index}/>
<Route path="/levelone/:id" component={LevelOne}>
<Route path="/leveltwo/:idd" component={LevelTwo}/>
</Route>
</Route>
)
ReactDOM.render(<Router history={ hashHistory } routes={routes}></Router>, document.getElementById('app'));
<script src="https://unpkg.com/react@15.1.0/dist/react-with-addons.js"></script>
<script src="https://unpkg.com/react-dom@15.1.0/dist/react-dom.js"></script>
<script src="https://npmcdn.com/react-router@3.0.0/umd/ReactRouter.js" charset="utf-8"></script>
<div id="app"><div>
在上面的代码中,我链接到/levelone/1/leveltwo/5
来自App
的组件[react-router] Location "/levelone/1/leveltwo/5" did not match any routes
,该组件无效并显示错误LevelOne
。
但是,如果我将链接放在组件var LevelOne = React.createClass({
render : function() {
return (
<div>
<h2>This is LevelOne</h2>
<div><Link to="leveltwo/5">Go to LevelTwo</Link></div>
{this.props.children}
</div>
)
}
})
中,就像在下面的代码片段中一样,链接将指向LevelTwo就像我想要的那样
{{1}}
如果我想从最外面的组件链接到LevelTwo,我该怎么办?
答案 0 :(得分:3)
LevelOne
组件(<Link to="leveltwo/5">Go to LevelTwo</Link>
)中定义的路径是此处的问题。您的所有链接都必须使用绝对路径。
引自https://github.com/ReactTraining/react-router/blob/master/docs/API.md#link
<强>道具强>
to
位置描述符。通常这是一个字符串或对象,具有以下语义:
...
所以你的路径应该改为 <Link to={"/levelone/" + this.props.params.id + "/leveltwo/5"}>Go to LevelTwo</Link>
。
编辑:对不起,凌晨1点,我的阅读能力已经从悬崖上掉下来了。嵌套路由时,在您打算实际使用相对路径时不要使用绝对路径时要小心。您的路线定义
<Route path="/leveltwo/:idd" component={LevelTwo}/>
应改为:
<Route path="leveltwo/:idd" component={LevelTwo}/>
<div><Link to="leveltwo/5">Go to LevelTwo</Link></div>
正在工作的原因是因为<Link>
仅支持绝对路径(见上文)并且实际上指向/leveltwo/5
并且您最初使用绝对定义的路由定义路径。因此,尽管代码已经运行,但它实际上并没有按照您的预期运行。
答案 1 :(得分:2)
我认为问题在于您在子路径定义中有/
。
只需改变一下:
<Route path="/leveltwo/:idd" component={LevelTwo}/>
到
<Route path="leveltwo/:idd" component={LevelTwo}/>
