download text from url and put its content to label in javascript

To download the text content of a URL and put its content into a label, you can use an HTTP request and DOM manipulation in JavaScript. Here's how you can do it using async/await syntax:

index.tsx
async function getTextFromUrl(url) {
  const response = await fetch(url);
  const text = await response.text();
  return text;
}

async function putTextInLabel(url, labelId) {
  const text = await getTextFromUrl(url);
  const label = document.getElementById(labelId);
  label.innerText = text;
}

// example usage:
putTextInLabel('https://example.com/text.txt', 'mylabel');

The getTextFromUrl function takes a URL as a parameter and returns the text content as a Promise. It uses the fetch API to make the HTTP request, and the text method of the response object to get the text content.

The putTextInLabel function takes a URL and a label ID as parameters. It calls getTextFromUrl to retrieve the text content and then uses getElementById to get the label element and sets its innerText property to the text content.

To use it, call putTextInLabel with the URL and the ID of the label you want to populate with the text content.
