I want keep the line breaks after I do some logic in my string value for a textarea element. Lets say I have this string from my textarea:
"Test
Newline here"
array: ["Test\nNewline", "here"]
How can I save it to be like this: ["Test", "\n", "Newline", "here"]
My code:
let bodyText = "Test
Newline here"
let bodyTextArray = bodyText.split(/ |\n|(?=\n)/g)
Basically what is happening it it is splitting and removing the spaces and "\n". using positive lookahead isn't working, I was trying with negative look ahead with no success.
Any ideas?
You can match those:
let bodyText = `Test
Newline here`
let bodyTextArray = bodyText.match(/^\n|\S+/gm)
console.log(bodyTextArray)Details:
^\n - start of a line and a newline| - or\S+ - any one or more non-whitespace chars.To support CRLF, LF or CR line endings, use
/^(?:\r\n?|\n)|\S+/gm
where (?:\r\n?|\n) replaced \n and matches either a CR and an optional LF char, or just an LF char.
You need this
let bodyText = "Test
Newline here"
let bodyTextArray = bodyText.split(/( |\n)/)
If you put capturing () around what you are splitting on then that is added to the output
You can use a split using this regex:
/(\n)+|\s+/
Code:
const input = `Test
Newline here`;
var arr = input.split(/(\n)+|\s+/);
console.log(arr.filter(Boolean));Explanation:
/(\n)+|\s+/ splits input on 1+ newlines while capturing a single newline (to make \n available in output array after split) or 1+ whitespace.filter(Boolean) removes empty or undefined entries from array
