JavaScript (regex): excluding results matching

Question

I have this text: nisi non text600 elit , where 600 is added dynamically. How can i get it?

var str = ('nisi non text600 elit').match(/text\d+/);
alert(str);

This warns text600 , how can I warn only 600 without further replacing the word text (if possible)?

Any help is appreciated, thanks!

Use parentheses to search for a group in a regular expression:

var str = ('nisi non text600 elit').match(/text(\d+)/)[1];

Note. A regular expression literal is not a string, so you should not have apostrophes.

The result will be an array, there the index 0is all the match applied to the string, and the following signs are your captures.
