JavaScript(regex): excluding matches from output

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 alerts text600, how can I alert only 600 without an additional replace of the word text(if that is possible)?

Any help is appreciated, thank you!

Answer 1

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

Answer 2

Use parentheses to catch a group in the regular expression:

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

Note: A regular expression literal is not a string, so you shouldn't have apostrophes around it.
