react-router4 实现js路由跳转

使用 withRouter

withRouter高阶组件，提供了history让你使用~

import React from "react";
import {withRouter} from "react-router-dom";

class MyComponent extends React.Component {
  ...
  myFunction() {
    this.props.history.push("/some/Path");
  }
  ...
}
export default withRouter(MyComponent);

这是官方推荐做法哦。但是这种方法用起来有点难受，比如我们想在redux里面使用路由的时候，我们只能在组件把history传递过去。。https://reacttraining.com/react-router/web/api/withRouter

// This gets around shouldComponentUpdate
withRouter(connect(...)(MyComponent))
// or
compose(
  withRouter,
  connect(...)
)(MyComponent)
