Line Break - React Prop

Admin 1
Viewed 1029

I have a component <Ren1 text="Line1\nLine2\nLine3" /> ...

function Ren1({text}){
  return <p>{text}</p>;
}
export default Ren1

How do I add the line break from \n from when it comes from the database?

Needed output:

Line1
Line2
Line3

Thank you in advance for your help

You can do it without splitting the text value.

First, put curly braces around the text prop when you are passing it:

<Text text={"One \n Two \n Three"} />

Then use whiteSpace: "pre-line" style

<div style={{ whiteSpace: "pre-line" }}>{props.text}</div>

You could create an array containing the actual text lines with split (i.e. const lines = text.split('\n')).

Then you could map over this array to render the lines individually.

lines.map(line => ...)

Split the text prop on "\n" and map the result array into the p tag within a Fragment with br element.

function Ren1({ text }) {
  return (
    <p>
      {text.split("\\n").map((line, index) => (
        <React.Fragment key={index}>
          {line}
          <br />
        </React.Fragment>
      ))}
    </p>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(
  <Ren1 text="Line1\nLine2\nLine3" />,
  rootElement
);
