javascript regex to extract a word from middle of 6 sentence

i have a string like following:

Assigned to ram on 2010-04-22 12:30:13.0

i need to extract the third word (ram). I tried the below regex, its not working.

/\s[a-zA-Z]*\s/

an开发者_如何转开发y help to fix this would be greatly appreciated.

If your input is so well defined (6 words, need to get third), why not just use string methods:

'Assigned to ram on 2010-04-22 12:30:13.0'.split(' ')[2]

Instead of using a regular expression, why not just split the string on spaces and grab the third one?

var s = "Assigned to ram on 2010-04-22 12:30:13.0";
var third = s.split(/\s+/)[2];
// third will be "ram"

Try

a = "Assigned to ram on 2010-04-22 12:30:13.0"

re = /\w+\W+\w+\W+(\w+)/

alert(a.match(re)[1])
