I have been testing with SunEditor since I want to pre-load an HTML text stored in DB and let users modify it if necessary. I'm passing a ref variable from parent so when the submit button is clicked he could get the value and save modificacions. setContents is just working sometimes. When I save the project and is piled again text appeared. But if I use the app or refresh the window text dissapear. I have checked that the variable still has the value. I'm new to React and I'm not sure If I'm doing it wrong or just suneditor-react failing. Can you help me?

Here is my code:

export const TranslationArea = React.forwardRef((props, ref) =>{    
    
    const handleEditorChange = (value) => {
        console.log(value);  
    
        ref.current= value;
      }
     const handleClick  = () => {
         console.log(ref.current);
     } 
    return(
        <div>
            <h2>{props.title}</h2>
                <SunEditor 
                    autoFocus={true}
                    width="100%"
                    height="150px"
                    setOptions={{
                        buttonList: [
                            // default
                            ['undo', 'redo'],
                            ['bold', 'underline', 'italic', 'list'],
                            ['table', 'link', 'image'],
                            ['fullScreen']
                        ]
                    
                    }}
                    setContents={props.content}
                    onChange={handleEditorChange}
            
                />
                <div>{props.content}</div>
            <button onClick={handleClick}>Content</button>
        </div>
    );
});

Here is the screenshot with content properly loaded inside SunEditor div (only when piling project):

If I refresh the page or navigate to the same link...

I have displayed a div with the same props.content just to check that fowardRef is working. Why setContents is now working? I have inspect with React tools and the property is loaded:

Any idea?

I'm passing a ref variable from parent so when the submit button is clicked he could get the value and save modifications.

If all you need to access is the value, let's pass down a callback instead. We'll call it onSumbit and it will be a function which takes the string value from the SunEditor ponent.

In order to have access to the current edited value, I am using a local state in the TranslationArea ponent and updating that state through the editor's onChange method. Then when the submit button is clicked, I call onSubmit with the value of content from the local state. (There might be another way to do this but I'm not familiar with SunEditor).

The TranslationArea ponent looks like this:

export const TranslationArea = ({initialContent = "", title, onSubmit}) => {    
  const [content, setContent] = useState(initialContent);

  return(
      <div>
          <h2>{title}</h2>
              <SunEditor 
                  autoFocus={true}
                  width="100%"
                  height="150px"
                  setOptions={{
                      buttonList: [
                          // default
                          ['undo', 'redo'],
                          ['bold', 'underline', 'italic', 'list'],
                          ['table', 'link', 'image'],
                          ['fullScreen']
                      ]
                  
                  }}
                  setContents={initialContent}
                  onChange={setContent}
              />
              <div>{content}</div>
          <button onClick={() => onSubmit(content)}>Submit</button>
      </div>
  );
};

I tested it in my CodeSandbox by giving it an onSubmit function which logs the submitted content, but you can do whatever you need to with it.

export default function App() {
  const initialContent = "Hello World";
  const onSubmit = (content: string) => {
    console.log("Submitted Content", content);
  };

  return (
    <div className="App">
      <TranslationArea
        initialContent={initialContent}
        onSubmit={onSubmit}
        title="Edit Text"
      />
    </div>
  );
}

CodeSandbox Link

const [content,setContent] = useState('');
var initialContent = YOUR_PROPS_FROM_DB_STATE;

In SunEditor Component:

<SunEditor 
defaultValue={initialContent}
setContents={YOUR_PROPS_FROM_DB_STATE}
placeholder={placeholder}
onChange={setContent}
/>

In my case YOUR_PROPS_FROM_DB is state es from parent ponent. placeholder - any variable or string inside. Sure that is not the best solution. But somehow it works.

Hope this helps! Regards,
