How do I split a string with multiple separators in JavaScript?

How do I split a string with multiple separators in JavaScript?

I'm trying to split on both commas and spaces, but AFAIK JavaScript's split() function only supports one separator.

Solution

  • Pass in a regexp as the parameter:

    js> "Hello awesome, world!".split(/[\s,]+/)
Hello,awesome,world!

    Edited to add:

    You can get the last element by selecting the length of the array minus 1:

    >>> bits = "Hello awesome, world!".split(/[\s,]+/)
["Hello", "awesome", "world!"]
>>> bit = bits[bits.length - 1]
"world!"

    ... and if the pattern doesn't match:

    >>> bits = "Hello awesome, world!".split(/foo/)
["Hello awesome, world!"]
>>> bits[bits.length - 1]
"Hello awesome, world!"
