Ckeditor5 Vue JS 3自定义上传适配器问题

Ceditor5 VueJS3 custom upload adapter problem

我正在使用 VueJS3 为 CKEditor 5 实现自定义上传适配器。基于此 中提供的示例,我执行了以下操作:

  1. 我创建了 UploadAdapter.vue 文件(下面附有代码)
  2. 我在我的vue组件中导入了文件import UploadAdapter from '@/Shared/UploadAdapter';
  3. 然后我将 Uploader() 函数放在组件的方法中,并将 extraPlugins: [this.uploader] 包含在 ck 的 editorConfig 中。 (在下面找到vue组件的代码)

现在的问题是,当我将图像拖放到编辑器中时,出现了一个奇怪的错误,它告诉我 ReferenceError: $ is not defined

google 上的所有搜索结果都指出此错误是由于 jquery 缺失引起的。这让我感到困惑,因为我使用的是 vuejs 3 而不是 jquery。尽管如此,我还是使用 npm -i jquery 安装了 jquery 并将其导入到我的 vue 组件中,但仍然没有成功。

我需要帮助指出是什么触发了 ReferenceError: $ is not defined

这是我的UploadAdapter.vue文件

<script>
 export default class UploadAdapter {
    constructor( loader ) {
        // The file loader instance to use during the upload.
        this.loader = loader;
    }

    // Starts the upload process.
    upload() {
        return this.loader.file
            .then( file => new Promise( ( resolve, reject ) => {
                this._initRequest();
                this._initListeners( resolve, reject, file );
                this._sendRequest( file );
            } ) );
    }

    // Aborts the upload process.
    abort() {
        if ( this.xhr ) {
            this.xhr.abort();
        }
    }

    // Initializes the XMLHttpRequest object using the URL passed to the constructor.
    _initRequest() {
        const xhr = this.xhr = new XMLHttpRequest();

        xhr.open( 'POST', '/editor/file/upload', true );
        xhr.setRequestHeader('x-csrf-token', $('meta[name="csrf-token"]').attr('content'));
        //_token: '{{csrf_token()}}'
        xhr.responseType = 'json';
    }

    // Initializes XMLHttpRequest listeners.
    _initListeners( resolve, reject, file ) {
        const xhr = this.xhr;
        const loader = this.loader;
        const genericErrorText = `Couldn't upload file: ${ file.name }.`;

        xhr.addEventListener( 'error', () => reject( genericErrorText ) );
        xhr.addEventListener( 'abort', () => reject() );
        xhr.addEventListener( 'load', () => {
            const response = xhr.response;

            if ( !response || response.error ) {
                return reject( response && response.error ? response.error.message : genericErrorText );
            }

            resolve( {
                default: response.url
            } );
        } );

        if ( xhr.upload ) {
            xhr.upload.addEventListener( 'progress', evt => {
                if ( evt.lengthComputable ) {
                    loader.uploadTotal = evt.total;
                    loader.uploaded = evt.loaded;
                }
            } );
        }
    }

    // Prepares the data and sends the request.
    _sendRequest( file ) {
        // Prepare the form data.
        const data = new FormData();

        data.append( 'upload', file );

        // Send the request.
        this.xhr.send( data );
    }
}
</script>

这是我的 vue 组件

            };
        },
    }
}

谢谢!

您似乎正试图在 UpoadAdapter.vue 中使用 jQuery 来 select 来自 csrf-token 元标记的内容。

xhr.setRequestHeader('x-csrf-token', $('meta[name="csrf-token"]').attr('content'));

您可以尝试两件事

  • 将 jQuery 导入 UploadAdapter.vue:(我建议在使用 Vue 时不要这样做)
import { $ } from 'jQuery';
  • 使用 vanilla JS select csrf-token 内容:
const csrfToken = document.querySelector('meta[name="csrf-token"]').getAttribute('content');
if (csrfToken) {
  xhr.setRequestHeader('x-csrf-token', csrfToken);
}
