Toast未呈现(react-toastify组件)

Question

我正在使用react-toastify，但我无法获得一个简单的吐司来呈现...

import React from "react";
import { toast } from 'react-toastify';

class MyView extends React.Component<{}, {}> {

    constructor() {
        super();
        this.state = {

        };
    }

    componentDidMount() {
        toast("Hello", { autoClose: false });
    }

    notify = () => toast("Hello", { autoClose: false });

    render() {
        return (
           <div>
             <button onClick={this.notify}>Notify</button>
           </div>
      )}
}

package.json (在“依赖项”部分)

"react": "^16.2.0",
"react-toastify": "^3.2.2"

如果我调试它，我看到我的toast已排队，_EventManager2永远不会获得通常从队列中发出toast的_constant.ACTION.MOUNTED事件……

/**
 * Wait until the ToastContainer is mounted to dispatch the toast
 * and attach isActive method
 */
_EventManager2.default.on(_constant.ACTION.MOUNTED, function (containerInstance) {
  container = containerInstance;

  toaster.isActive = function (id) {
    return container.isToastActive(id);
  };

  queue.forEach(function (item) {
    _EventManager2.default.emit(item.action, item.content, item.options);
  });
  queue = [];
});

..so ToastContainer可能有点问题，但是什么问题呢？我只使用文档中的示例代码。

谢谢你的帮助!

Answer 1

你还得import 'react-toastify/dist/ReactToastify.css';

  import React, { Component } from 'react';
  import { ToastContainer, toast } from 'react-toastify';
  import 'react-toastify/dist/ReactToastify.css';
  // minified version is also included
  // import 'react-toastify/dist/ReactToastify.min.css';

  class App extends Component {
    notify = () => toast("Wow so easy !");

    render(){
      return (
        <div>
        <button onClick={this.notify}>Notify !</button>
          <ToastContainer />
        </div>
      );
    }
  }

在声明类之前，添加以下行：

toast.configure();

其他解决方案对我不起作用--原来我没有向toast.*函数传递字符串。例如：

  getSomethingFromApi()
     .then((response) =>  { 
         // this works fine because response.message is a string
         toast.notify(response.message)
      })
     .catch((error) => {
         // this will fail to render because error is an object, not a string
         toast.error(error)
      })
