Question

I have a string that may contains Twitter hashtags. I’d like to strip it from the string. How should I do this? I’m trying to use the RegExp class but it doesn’t seem to work. What am I doing wrong?

This is my code:

var regexp = new RegExp('\b#\w\w+');
postText = postText.replace(regexp, '');

Answer 1

Here ya go:

postText = 'this is a #test of #hashtags';
var regexp = /#\S+/g;
postText = postText.replace(regexp, 'REPLACED');

This uses the ‘g’ attribute which means ‘find ALL matches’, instead of stopping at the first occurrence.
