Javascript regular expression issue

I have more strings split by 2 spaces , something like:

abc  adfdfg  aefdf  xcv
   ^^      ^^     ^^

What is the correct regular expr开发者_如何转开发ession to retrieve that strings. Thanks.

LE: what i tried is : split(/[a-zA-Z\-]\s{2}/); and it is not working

The easiest way to break that into separate words is like this (requires exactly two spaces):

var str = "abc  adfdfg  aefdf  xcv";
var words = str.split("  ");

words is now an array of words from the string.

If you want to split on any amount of whitespace, you can use a regular expression as the split argument:

var str = "abc  adfdfg  aefdf  xcv";
var words = str.split(/\s+/);

Demo here: http://jsfiddle.net/jfriend00/pkUh9/

If you want to split on two or more units of whitespace, you can use this regular expression as the split argument:

var str = "abc  adfdfg  aefdf  xcv";
var words = str.split(/\s{2,}/);

Assume your string to be declared using var string = 'abc adfdfg aefdf xcv'. Then use:

string = string.split(/\s{2,}/); returns a list of substrings, split by at least two white-space characters (including tabs and newlines). If you only want to split spaces, use (space) instead of \s.

Just

'abc adfdfg aefdf xcv'.split(/\s+/)
