Question

For example suppose # denotes a special word as follows

I took a #lovely trip to the #zoo today. We had a #wonderful time. With RegEx is it possible to extract something like

#lovely#zoo#wonderful

Answer 1

Use string.match

var str = "I took a #lovely trip to the #zoo today. We had a #wonderful time"
str.match(/#\w+/g); // #lovely,#zoo,#wonderful 

Might want to tweak the regex to include numbers and symbols depending on your needs.

/#[\w\d]+/g for letters and digits, /#\S+/g for anything that is not whitespace.

EDIT: I’ll add that the g at the end means that it will find all matches and not only the first one.
