regex to split number from string

Question

How to split and select which is number using regex. User can enter string like:

1dozen 3 dozen dozen1 <= unlikely but assume user will type that too

30/kg

I still find out with the incomplete one:

/[a-z](?=\d)|\d(?=[a-z])/i

But missing space and forward slash. Can anyone help me?

If the user only enters number plus text then parseInt(str,10) will do the job — mplungjan

The lookarounds are completely unnecessary here!

The code:

var text = "1dozen 3 dozen dozen1 30/kg";
var regex = /(\d+\.|\d+)+/g;
alert(text.match(regex));

You get a match object with all of your numbers.

The script above correctly alerts 1,3,1,30.

var str = '1dozen 3 dozen dozen1 30/kg';
str.match(/\d+/g); // ["1", "3", "1", "30"]
