javascriptstringsplit

Split string with limit, where last string contains the remainder

e.g. if I run this javascript: 

var str = 'hello_world_there';
var parts = str.split('_', 2);

var p1 = parts[0];
var p2 = parts[1];

at the end, p1 contains "hello", and p2 contains "world".

I'd like p1 to contain "hello", and p2 to contain "world_there". i.e. I want p2 to contain the rest of the string, regardless of how many underscores it has (similar to how c#'s String.Split(char[] separator, int count) behaves.

Any workarounds ?

Solution 
  • var str = 'hello_world_there';
var parts = str.split('_');

var p1 = parts[0];
var p2 = parts.slice(1).join('_');

    This will do an ordinary split, but then merge everything past the first match.
