• React中使用富文本编辑器react-draft-wysiwyg


    在React中用react-draft-wysiwyg:// react-draft-wysiwyg begin

    import { EditorState, convertToRaw, ContentState } from 'draft-js';
    import { Editor } from 'react-draft-wysiwyg';
    import draftToHtml from 'draftjs-to-html';
    import htmlToDraft from 'html-to-draftjs';
    import 'react-draft-wysiwyg/dist/react-draft-wysiwyg.css'
    // react-draft-wysiwyg end
    state = {
            showRichText: false, // react-draft-wysiwyg
            editorContent: '', // react-draft-wysiwyg
            editorState: '', // react-draft-wysiwyg
        };
    点击并拖拽以移动
    /**
         *
         * @react-draft-wysiwyg begin
         */
        handleClearContent = () => {
            this.setState({
                editorState: ''
            })
        }
    
        handleGetText = () => {
            this.setState({
                showRichText: true
            })
        }
    
        onEditorChange = (editorContent) => {
            this.setState({
                editorContent,
            });
        };
    
        onEditorStateChange = (editorState) => {
            this.setState({
                editorState
            });
        };
        // @react-draft-wysiwyg end
    提交时将富文本转换为含html的文本: 
    addModalHandleOk = e => {
            const _this = this;
            this.addModalFormRef.current.validateFields()
                .then(values => {
                    console.log(this.state.editorContent);
                    const params = {
                        title: values.title,
                        content: draftToHtml(convertToRaw(this.state.editorState.getCurrentContent()))
                    };
    
                    axios.post(`http://localhost:5555/api/add_blog`, qs.stringify(params)).then((resp) => {
                        if (resp.ret) {
                            console.log(resp.msg);
                        } else {
                            this.addModalFormRef.current.resetFields();
                            this.setState({
                                addModalVisible: false
                            });
                            this.getData(1, 5);
                        }
                    }, (err) => {
                        console.log(err);
                    });
                })
                .catch(info => {
                    console.log('Validate Failed:', info);
                });
        }
    获取时的文本含有html标签,所以在Modal中用“<div dangerouslySetInnerHTML={{__html: this.state.blogDetail}} style={{height: 300, overflow: 'auto'}}/>”转换成html标签。
    /**
         * 显示blog Modal
         */
        handleShowDetailBlog = (id) => {
            axios.get(`http://localhost:5555/api/get_blog_detail?id=${id}`, {}).then((resp) => {
    
                if (resp.data.ret) {
                    this.setState({
                        showBlogModalVisible: true,
                        blogDetail: resp.data.content
                    })
                } else {
    
                }
            }, (err) => {
                console.log(err);
            });
        }
