如何使用 react-router 和 ES6 类模拟 window.location [英] How to emulate window.location with react-router and ES6 classes

问题描述

我使用的是 react-router，所以我在整个应用程序中使用 <Link/> 组件作为链接，在某些情况下，我需要根据用户输入动态生成链接，所以我需要类似 window.location 的东西，但没有页面刷新.

I'm using react-router, so I use the <Link /> component for my links throughout the app, in some cases I need to dynamically generate the link based on user input, so I need something like window.location, but without the page refresh.

我发现了这个小笔记 - (https://github.com/rackt/react-router/issues/835) - 我尝试使用 this.context.router.transitionTo(mylink) 但我遇到了上下文问题...

I found this little note - (https://github.com/rackt/react-router/issues/835) - i tried using this.context.router.transitionTo(mylink) but I'm having issues with context...

这让我(https://github.com/rackt/react-router/issues/1059)，但是上下文返回和空对象，所以当我尝试做类似的事情时: this.context.router.transitionTo(mylink); 我得到 Cannot read属性 'transitionTo' of undefined (如果我尝试在构造函数中执行类似 set this.context = context 的操作).

which led me to (https://github.com/rackt/react-router/issues/1059), however context returns and empty object, so when I try todo something like: this.context.router.transitionTo(mylink); I get Cannot read property 'transitionTo' of undefined (if I try to do something like set this.context = context within the constructor).

不要拖延，但我也厌倦了过多地弄乱上下文，因为它是故意没有记录的，因为它仍在进行中，所以我已经阅读了.

Not to drag on, but I'm also weary of messing too much with context as it is undocumented on purpose as it's still a work in progress, so I've read.

有没有人遇到过类似的问题?

Has anyone come across a similar issue?

推荐答案

在这里找到解决方案:https://github.com/rackt/react-router/issues/975，这里是:https://github.com/rackt/react-router/issues/1499

Found a solution here: https://github.com/rackt/react-router/issues/975, and here: https://github.com/rackt/react-router/issues/1499

在构造函数中需要:

class SidebarFilter extends React.Component {

    constructor(props, context) {
        super(props, context);

还需要添加一个静态属性:

Also need to add a static property:

SidebarFilter.contextTypes = {
  router: React.PropTypes.func.isRequired
};

然后我可以打电话:

this.context.router.transitionTo(/path-to-link);
