How to check if string contains multiple spaces and returns in Javascript?

Question

I want to check to see if an item in an array/list of strings has 1 or more spaces and/or 1 or more line breaks.

What exactly would I check for in an if statement, if I wanted to check to see if the string item has this?

The least you can do before asking a question is search: [javascript] string contains space — Felix Kling

I've tried checking if the item was just a "\n", but that only works if it's one space. I've also tried "\n+" which I thought would mean multiple "\n"s, but it doesn't. I've researched a bit already, but couldn't find anyone else with this question. — Owen M

Maybe something like this: if (/\s*/.test("hello\n")) { alert("foo"); } — Cypher

Possibly:

count = string.search(/\s/);

Where string is your input, \s is the regex for space characters, and count is the total number found in string.
