Question

这是一个有效的调查.js，其中包含反应示例：http://plnkr.co/edit/qXdeQa6x2FHRg0YrOlPL?p=preview

我的html也确实包含了<script src="https://unpkg.com/survey-react"></script>。

在我的main.jsx中，我正在调用基于json文件和多个反应组件填充的div的渲染，在我的json数组中，我对survey.js也有一个问题json对象。我想要实现的是在解析数组时到达问题对象时进行调查。

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是在浏览器中我得到了控制台错误：

TypeError： WEBPACK_IMPORTED_MODULE_1_react 未定义[学习更多] ReferenceError：未定义questionid

似乎我试图以错误的方式做到这一点，但如何正确地做到这一点？我是新手，不熟悉在组件中使用reactDOM，也是我在survey.js上的第一个项目。

感谢您的帮助。

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'));
