Question

I have a string in javascript like this:

some string 27

or it could be

some string

or

string 123

or even

string 23A – or – string 23 A

So in other words, it’s always a string. Sometimes it ends with a number, sometimes not. And sometimes the number has a letter (only one) at the end.

Now the problem is, that I have to split this string. I need the string and number (including the letter if there’s one) stored in two variables. Like in:

some string 27

var str = “some string”
var number = 27;

I probably need to do this with regex. But i have no idea how.

Can someone please help me out with this?

Answer 1

You should use this regex:

var arr = s.match(/^(\D+?)\s*(\d+(?:\s+[A-Z])?)$/i);

Then use:

var str = arr[1];
var number = arr[2];

Assuming s is your variable containing original text;
