React之Json编辑器

我们先看下效果，这个白色是不是非常不错？没有太多复杂的功能，就是当一个简洁显示json并且进行编辑的功能


接下来是代码部分

import AceEditor from 'react-ace';
import { Button, Modal } from 'antd';
import './styles.css';

// Import ace editor themes and modes
import 'ace-builds/src-noconflict/mode-json';
import 'ace-builds/src-noconflict/theme-github';

function App() {
  const [jsonContent, setJsonContent] = useState(`{
  "greeting": "Hello World",
  "color": "#ff3e00",
  "ok": true,
  "values": [1, 2, 3, 4, 5]
}`);
  const [isModalOpen, setIsModalOpen] = useState(false);

  const handleEditorChange = (value: string) => {
    setJsonContent(value);
  };

  const handleSubmit = () => {
    setIsModalOpen(true);
  };

return (
  <div className="json-view-container">
    <h2>JSON Editor</h2>
    <div className="editor-wrapper">
      <AceEditor
        mode="json"
        theme="github"
        value={jsonContent}
        onChange={handleEditorChange}
        name="json-editor"
        editorProps={{ $blockScrolling: true }}
        setOptions={{
          showLineNumbers: true,
          tabSize: 2,
          useWorker: false,
          fontFamily: 'Fira Code, monospace',
          fontSize: 16,
          printMargin: false 
        }}
        width="100%"
        height="400px"
      />
    </div>
    <div className="button-container">
      <Button type="primary" onClick={handleSubmit}>
        提交
      </Button>
    </div>
    <Modal
      title="JSON Content"
      open={isModalOpen}
      onOk={() => setIsModalOpen(false)}
      onCancel={() => setIsModalOpen(false)}
    >
      <pre>{jsonContent}</pre>
    </Modal>
  </div>
);}
export default App;
