How to check if a date string already has two forward slashes in it?

Question

I need your help,

Is there a way to code a javascript function that would regex and test a string or using any other means to check if a date string already has the two forward slashes in it? ie. dd/mm/yyyy

regex('04/07/2014') { return true }

Thanks in advance for all your help?

You can use a regex test:

/\/.*\//.test("04/07/2014")

/\d{2}\/\d{2}\/\d{4}/ ? – mplungjan Jul 04 '14 at 14:35
@mplungjan, Well, you could use `/^\d{2}\/\d{2}\/\d{4}$/` to check if it's date-like, but the OP asked to check for two slashes. – ikegami Jul 04 '14 at 14:36
which will match //, no? – mplungjan Jul 04 '14 at 14:44
@mplungjan, Yes, it will match `//` as requested. – ikegami Jul 04 '14 at 14:57
which is what OP thinks he wants :) – mplungjan Jul 04 '14 at 15:00
@mplungjan, If he wants to check if he has a date (even though he said he had a date), he can use the pattern in the second comment. – ikegami Jul 04 '14 at 15:01

You can use this regex:

/([^/]*\/){2}/

to check if input has at least 2 forward slashes.

use /\/.*\//.test( str ) it returns true if str has two forward slashes in it.
