javascript由空白3个元素分割

Question

我有一些行。。例如：

var line;
line = "INFO  2014-10-08 15:01:17,233 [localhost-startStop-1] Main directory: C:WORKSPACE";
line = "ERROR 2014-10-08 15:01:16,646 [localhost-startStop-1] Cannot alter it is not a table.";
var headerArray = line.split("\s", 3);
//headerArray returns array of 1 element "INFO  2014-10-08 15:01:17,233 [localhost-startStop-1] Main directory: C:WORKSPACE"; don't know why..

但我只想要｛"INFO"，"2014-10-08"，"15:01:17233"｝，然后是｛"ERROR"，"2014-10-08"，"15:01:16646"｝

您可以在删除其余部分后进行拆分。

var line = "ERROR 2014-10-08 15:01:16,646 [localhost-startStop-1] Cannot alter it is not a table.";
var arr = line.replace(/s+/g," ").replace(/s[.+$/,"").split(" ");
console.log(arr);
