Regex Jquery Skip/Count + 3 Characters - 【StackMirror】|jquery|regex|count|skip

Given a string such as: "2.jpg 3 Pic.png 4 Pic For.gif ..." I need to get each image name. Ideally, with regex, I'd start at the period, then count 3 characters, and voila.

What I've got so far trims the file type too, I want to preserve that, since it varies.

    var words = $(".Input_Field").val().split(/\..{3} /g);

The above produces:

"2,3 Pic,4 Pic For, ..."

I want the extension back;

"2.jpg,3 Pic.png,4 Pic For.gif, ..."

EDIT

Just to clarify, the issue is that the filename has spaces, and there's a space after the extension. What I have going for me is that extensions will always be .xxx .

Any tips?

SOLUTION

(/(.*?..{3}) /g)

Produces empties almost every other array item (not quite), easy to get rid of with an if clause.

Thanks everyone!

Are you looking to get the whole image name or just the extension? I'm confused because you say "I'd start at the period, then count 3 characters, and voila" which implies you only need the extension - j-u-s-t-i-n 2012-04-05 21:17

Try match instead of split.

var words = $(".Input_Field").val().match(/(\S.*?\..{3})/g)

This works but you'll have a trailing whitespace on your filenames.. So remember to trim them. - barsju 2012-04-05 21:15

Changed the Regex, should now be without the trailing whitespac - robkub 2012-04-05 21:21

@robkub - I went with (/(.*?..{3}) /g), which produced empties that were easy to get rid of with an if clause. Together, works perfect. Thanks - C_K 2012-04-05 21:42
