吐司没有呈现(反应 - 组合成分)

Question

我正在使用react-toastify,我无法得到一个简单的吐司...

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"部分中)

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

如果我调试它,我看到我的toast排队,_EventManager2永远不会得到通常从队列中发出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 = [];
});

..那么ToastContainer可能有问题,但是什么？我只是使用文档中的示例代码.

谢谢您的帮助!

Answer 1

你也必须 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>
      );
    }
  }

Answer 2

在声明您的类之前，添加以下行：

toast.configure();

Answer 3

使用命令安装react-toastify

npm i react-toastify

然后：

import {ToastContainer,toast} from 'react-toastify'

并作为回报添加

<ToastContainer />

之后当你这样做时toast('hy') 它会显示 toast

Answer 4

更好的是，导入缩小的 css：

import 'react-toastify/dist/ReactToastify.min.css';

或者如果您将其导入到 .scss 文件中

@import '~react-toastify/dist/ReactToastify.min.css';

其他解决方案对我不起作用 - 结果我没有将字符串传递给toast.*函数。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)
      })
