如何使用survey.js 渲染React 组件？

Question

这是一个带有反应示例的工作调查.js：http ://plnkr.co/edit/qXdeQa6x2FHRg0YrOlPL?p=preview

我的 html 也<script src="https://unpkg.com/survey-react"></script>包含在内。

在我的 main.jsx 中，我正在调用将基于 json 文件和多个反应组件填充的 div 的渲染，在我的 json 数组中，我也有一个用于survey.js 的问题 json 对象。我想要实现的是在解析数组时达到问题对象时呈现调查。

在我的顶级组件中，我有这样的要求：

  if (section.hasOwnProperty('questions')){
            return <Questions key={i+"questions"} id={i+"questions"} questions={section.questions} />;

Questions.jsx：

var React = require('react');
var ReactDOM = require('react-dom');
var Survey = require('survey-react');
var Questions = React.createClass({
    render: function() {
      Survey.Survey.cssType = "bootstrap";
      Survey.defaultBootstrapCss.navigationButton = "btn btn-green";
      window[this.props.id] = new Survey.Model( this.props.questions );
      var questionid = this.props.id;
        var idi = this.props.id.replace("questions","");
        return (
            <dt>
          <div id={this.props.id}></div>
          </div>
     </dt>
        );
    }
});
module.exports = Questions;
ReactDOM.render(<Survey.Survey model={window[questionid]} />, document.getElementById({questionid}));

它确实编译没有错误，但随后在浏览器中我收到控制台错误：

TypeError: WEBPACK_IMPORTED_MODULE_1_react is undefined[了解更多] ReferenceError: questionid is not defined

似乎我试图以错误的方式做这件事，但是如何正确地做呢？我是 React 新手，不熟悉在组件内使用 reactDOM，也是我在survey.js 上的第一个项目。

谢谢你的帮助。

请检查此代码：

import React, { Component } from 'react';
import { render } from 'react-dom';

import * as Survey from 'survey-react';
import 'survey-react/survey.css';

import 'bootstrap/dist/css/bootstrap.css'
import './style.css';

class App extends Component {
  componentWillMount() {    
    Survey.Survey.cssType = "bootstrap";
    Survey.defaultBootstrapCss.navigationButton = "btn btn-green";
  }

  render() {    
    var json = { title: "Product Feedback Survey Example", showProgressBar: "top", pages: [
        {questions: [
            { type: "matrix", name: "Quality", title: "Please indicate if you agree or disagree with the following statements",
                columns: [{ value: 1, text: "Strongly Disagree" },
                    { value: 2, text: "Disagree" },
                    { value: 3, text: "Neutral" },
                    { value: 4, text: "Agree" },
                    { value: 5, text: "Strongly Agree" }],
                rows: [{ value: "affordable", text: "Product is affordable" },
                    { value: "does what it claims", text: "Product does what it claims" },
                    { value: "better then others", text: "Product is better than other products on the market" },
                    { value: "easy to use", text: "Product is easy to use" }]},
            { type: "rating", name: "satisfaction", title: "How satisfied are you with the Product?",
                mininumRateDescription: "Not Satisfied", maximumRateDescription: "Completely satisfied" },
            { type: "rating", name: "recommend friends", visibleIf: "{satisfaction} > 3",
                title: "How likely are you to recommend the Product to a friend or co-worker?",
                mininumRateDescription: "Will not recommend", maximumRateDescription: "I will recommend" },
            { type: "comment", name: "suggestions", title:"What would make you more satisfied with the Product?", }
        ]},
        {questions: [
            { type: "radiogroup", name: "price to competitors",
                title: "Compared to our competitors, do you feel the Product is",
                choices: ["Less expensive", "Priced about the same", "More expensive", "Not sure"]},
            { type: "radiogroup", name: "price", title: "Do you feel our current price is merited by our product?",
                choices: ["correct|Yes, the price is about right",
                    "low|No, the price is too low for your product",
                    "high|No, the price is too high for your product"]},
            { type: "multipletext", name: "pricelimit", title: "What is the... ",
                items: [{ name: "mostamount", title: "Most amount you would every pay for a product like ours" },
                    { name: "leastamount", title: "The least amount you would feel comfortable paying" }]}
        ]},
        { questions: [
            { type: "text", name: "email",
                title: "Thank you for taking our survey. Your survey is almost complete, please enter your email address in the box below if you wish to participate in our drawing, then press the 'Submit' button."}
        ]}
    ]};

    var model = new Survey.Model(json);    
    return (
      <Survey.Survey model={model}/>
    );
  }
}

render(<App />, document.getElementById('root'));
