javascript - How can I use regex to get all the characters after a specific character, e.g. comma (",")

Question

Need a Regex to get all characters after , (not including it) from a variable. This variable can contain for example

'SELECT___100E___7',24
'SELECT___100E___7',1
'SELECT___100E___7',286
'SELECT___100E___7',5147

Note: There can be any length of characters after the , in this variable.

An explanation of the regexp would be a added help for the novice :)

Edit: a javascript answer would be just as good

Answer 1

You don't need regex to do this. Here's an example :

var str = "'SELECT___100E___7',24";
var afterComma = str.substr(str.indexOf(",") + 1); // Contains 24 //
