Question

I’m looking for a good JavaScript RegEx to convert names to proper cases. For example:

John SMITH = John Smith  Mary O'SMITH = Mary O'Smith  E.t MCHYPHEN-SMITH = E.T McHyphen-Smith    John Middlename SMITH = John Middlename SMITH 

Well you get the idea.

Anyone come up with a comprehensive solution?

Answer 1

Something like this?

function fix_name(name) {     var replacer = function (whole,prefix,word) {         ret = [];         if (prefix) {             ret.push(prefix.charAt(0).toUpperCase());             ret.push(prefix.substr(1).toLowerCase());         }         ret.push(word.charAt(0).toUpperCase());         ret.push(word.substr(1).toLowerCase());         return ret.join('');     }     var pattern = /\b(ma?c)?([a-z]+)/ig;     return name.replace(pattern, replacer); }
