How to separate integer value from a string?

Question

I have a string that contains alphabets and integer like banana12,apple123, i wanted to separate integer value from a string. I have used split() function its working perfectly for single digit number ( orange1 ) but for double digit number it is returning only single digit.

 myString = banana12;
    var splits = myString.split(/(\d)/);
    var prodName = splits[0];
    var prodId = splits[1];

the prodId should be 12 but its returning only 1 as result.

what if string is something like "banana12with34" ..? what should be the output..? — Sudhir Bastakoti, Jun 04 '14 at 05:31

@Bergi I believe `split` itself is a bad choice here, what do you think? — thefourtheye, Jun 04 '14 at 05:37
@thefourtheye: Depends on whether `myString` is a sequence of multiple names & ids. Sure, `.match(/([a-z]+)(\d+)/i)` might be the better choice if not. — Bergi, Jun 04 '14 at 05:39
I agreed with Bergi and thefourtheye, here am using only single name and single id. so am going to choose split(). — Noor Fathima, Jun 04 '14 at 05:46
@NoorFathima: No, we did recommend to use `match` for exactly that! — Bergi, Jun 04 '14 at 05:51

This will do it-

myString = "banana1212";
    var splits = myString.split(/(\d+)/);
    var prodName = splits[0];
    var prodId = splits[1];
alert(prodId);

The result will be in a separate variable as you desired.

You can extract numbers like this:

var myString = "banana12";
var val = /\d+/.exec(myString);
alert(val); // shows '12'
