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

@Bergi I believe split itself is a bad choice here, what do you think? — thefourtheye

@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

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'

var splits = myString.split(/(\d{1,})/);
    var prodName = splits[0];
    var prodId = splits[1];
alert(prodId);
