Variable to array?

Question

I have a variable that looks like this: var regVar="Right Left Right;" And then I split them: regVar.split(); So what I am trying to do is to make the variable called regVar to be turned into an array. I thought that there was an .array() method, but I couldn't figure out how it works. If there is a jQuery method, that would be fantastic as well as plain JS. Thanks for you help in advance!

Answer 1

You have to specify what you're splitting on and re-assign to a variable, I assume it's the space in the string, so:

var regVar="Right Left Right;"
var arrayOfRegVar = regVar.split(" ");

console.log(arrayOfRegVar); //["Right", "Left", "Right"];

Answer 2

To split a string by spaces, use .split(" ");

You split a string by anything just by passing delimiter (ie. separator) as an argument to split().

Examples:
"hello world".split(' ') returns ["hello", "world"]
"google.com".split('.') returns ["google", "com"]
"415-283-8927".split('-') returns ["415", "283", "8927"]

Bonus:
If you use an empty string as the delimiter, the string is split by the character:
"helloworld".split('') returns ['h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd'] (an element in the array for every character including space)

However, if you use nothing (.split()), an array containing that unchanged string will be returned.
