Split a string into two using Javascript

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...

so you basically want all integers after 0

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);

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);

what if he has CORE instead of COR

Filip Roséen Over a year ago

@AnkitGautam I'm about to write an edit answering just that, hold on.. but according to the post it seems as if it's always three characters. but as said, hold on.

Hey that is exactly what I am looking for. There will be no "CORE" all of the combination will have only 3 letters. Thanks refp :)

Can you tell me why we use console.log(n) here?

console.log() shows the result in the browser's console, like google chrome's inspect element or firebug

I had just seen some one answer this question and before i could up vote it was deleted, hence posting the solution on his behalf.

var str='COR000050ABC';
var variable=parseFloat(/[0-9]+/g.exec(str));

though there was a small modification, added parseFloat

this doesn't follow the description posted by OP, also; why would you use parseFloat when parseInt will be sufficient - and OP requested an integer?
