any idea, help~

try split on:

/[\s,]+/ 

the character class [\s,] matches white space character or comma, , + tells match said class once or more. way don't end empty strings in split array.

or in 2 steps, first split on \s+ instead of single \s:

the following:

var text =  "         127.518037,37.834511\n" +  "          127.518037,37.834511\n" +  "          127.518103,37.834808\n" +  "          127.518103,37.834808\n" +  "          127.518169,37.835209\n" +  "          127.518169,37.835209\n" +  "          127.518147,37.835558\n" +  "          127.518147,37.835558\n" +  "          127.518059,37.835750\n" +  "          127.518059,37.835750\n" +  "          127.518081,37.835976\n" +  "          127.518081,37.835976\n" +  "          127.518411,37.836412\n" +  "          127.518411,37.836412\n" +  "          127.518697,37.836761\n" +  "          127.518697,37.836761\n" +  "          127.518719,37.837198\n" +  "          127.518719,37.837198\n" +  "          127.518741,37.837669\n" +  "          127.518741,37.837669\n" +  "          127.518477,37.838087\n" +  "          127.518477,37.838087\n" +  "          127.518433,37.838401\n" +  "          127.518433,37.838401";  var coords = text.split(/\s+/); for(item in coords){   var coords_list = coords[item].split(/,/);   print(coords_list); } 

will print:

127.518037,37.834511 127.518037,37.834511 127.518103,37.834808 127.518103,37.834808 127.518169,37.835209 127.518169,37.835209 127.518147,37.835558 127.518147,37.835558 127.518059,37.835750 127.518059,37.835750 127.518081,37.835976 127.518081,37.835976 127.518411,37.836412 127.518411,37.836412 127.518697,37.836761 127.518697,37.836761 127.518719,37.837198 127.518719,37.837198 127.518741,37.837669 127.518741,37.837669 127.518477,37.838087 127.518477,37.838087 127.518433,37.838401 127.518433,37.838401
