javascript - ReactJS + FineUploader : Error if template resides in render() function using JSX

Question

如果模板脚本标记驻留在我的组件的渲染函数中，我会收到以下错误:

在 Firefox 中: |TypeError: Node.removeChild 的参数 1 不是对象。|
在 Chrome 中:|未捕获类型错误:无法读取 null 的属性“hasAttribute”|

如果模板脚本标记放置在文档的静态部分中，则一切正常。有什么想法吗？

这是我的代码:

let React = require('react');
let ReactDOM = require('react-dom');

let qq = require('fine-uploader/fine-uploader/fine-uploader.js');

let FineUploadInputControl = React.createClass({
    getInitialState: function() { return { shared: this.props.shared }; },

    componentDidMount: function() {
        var galleryUploader = new qq.FineUploader({
            element: this.fineUploaderElement,
            template: this.fineUploaderTemplate,
            //template: 'qq-template-gallery',
            request: {
                endpoint: '/server/uploads'
            },
            thumbnails: {
                placeholders: {
                    waitingPath: '/source/placeholders/waiting-generic.png',
                    notAvailablePath: '/source/placeholders/not_available-generic.png'
                }
            },
            validation: {
                allowedExtensions: ['jpeg', 'jpg', 'gif', 'png']
            }
        });
     },

    render: function() {
        return (
             <div>

module.exports = FineUploadInputControl;

JSX 不太适合 <script>标签，因为它在渲染 DOM 和检测变化方面并没有真正的意义。 This Github ticket有更多信息。

如果需要将模板渲染到 DOM，可以尝试使用 dangerouslySetInnerHTML .

<script 
    ref={(ref) => this.fineUploaderTemplate = ref}
    type="text/template" id="qq-template-gallery">
    dangerouslySetInnerHTML={{__html: `
       <div class="qq-uploader-selector qq-uploader qq-gallery" qq-drop-area-text="Drop files here">
       ...
    `}}
 />
