Sometimes, we want to convert a textarea’s string value to a JavaScript array separated by new lines.

In this article, we’ll look at how to convert a textarea’s string value to a JavaScript array separated by new lines.

How to convert a textarea’s string value to a JavaScript array separated by new lines?

To convert a textarea’s string value to a JavaScript array separated by new lines, we can get the value of the text area.

Then we call split on the string with 'n' to split it by the new line character into an array.

For instance, we write:

<textarea></textarea>

to add a text area.

Then we write:

const textarea = document.querySelector("textarea");
textarea.onchange = (e) => {
  const arr = e.target.value.split('n')
  console.log(arr)
}

to listen to the change event by setting the textarea.onchange property to a function that gets the input value from e.target.value.

Then we call split with 'n' to split the string by the newline character into an array.
