Regex Expressions For Emoji

http://ift.tt/1LneX8A

function custom() {
var str = document.getElementById('original').innerHTML;
var replacement = str.replace(/\B:poop:\B/g,'REPLACED');
document.getElementById('replaced').innerHTML = replacement;
}
custom()

Yes = :poop: should be replaced with "REPLACED" No = :poop: should not be replaced. In other words, remain untouched.

Number 4, 5, 6 doesn't seems to follow the rule provided. I do know why, but I don't have much idea how to combine multiple expressions into one. I have tried many others but I just can't get them to work the way I wanted them to be. Odds aren't in my favor.

And yes, this is very similar to how Facebook emoji in chat box works.

New issue:

/(^|\s):bin:(\s|$)/gm

It is unable to scan and replace the one in the middle. How can I fix that?
