Use JavaScript regex to replace numerical HTML entities with their actual characters

Question

I\'m trying to use JavaScript & regex to replace numerical HTML entities with their actual Unicode characters, e.g.

foo's bar
→
foo\'s bar
         


        

Answer 1

"foo's bar".replace(/&#([^\s]*);/g, function(x, y) { return String.fromCharCode(y) })

First argument (x) is a "'" in current example. y is 39.
