Question

I have a string COR000001. I want to split it so that I get only the integer 1. If the String is like COR000555 I should get the integer 555. Thank you…

Answer 1

The easiest method to use is to get rid of the first three characters "COR", "MCR", "TCP", etc.. and then use parseInt with the appropriate parameters such as in the below.

var str = "COR000555";
var n   = parseInt (str.substr (3), 10); // force parseInt to treat every
                                         // given number as base10 (decimal)

console.log (n);

555

If the “key” in the beginning is not always limited to three characters you could use a regular-expression to get all the digits in the end of your string.

.. as in the below;

var n = parseInt (str.match (/\d+$/)[0], 10);
