how to make an regular expression in javascript to repeat

Question

How can I make it to validate this string:

word:word,word:word,

What I wrote this and works only for:

word:word,enithinggg

which is wrong.

/^(^([0-9a-zA-Z!\? ])+\:([0-9a-zA-Z!\?. ])+\,)+$/i

Answer 1

/^(([0-9a-zA-Z!\\?])+\\:([0-9a-zA-Z!\\?])+\\,?)+$/

should do it. You had ^ inside the first group, forcing it to match a newline. I'm not too familiar with javascript regular expressions, so I'm not sure what the i at the end was doing.
