A title-case filter for AngularJs
// Came from the comments here: https://gist.github.com/maruf-nc/5625869
app.filter('titlecase', function() {
return function (input) {
var smallWords = /^(a|an|and|as|at|but|by|en|for|if|in|nor|of|on|or|per|the|to|vs?\.?|via)$/i;
input = input.toLowerCase();
return input.replace(/[A-Za-z0-9\u00C0-\u00FF]+[^\s-]*/g, function(match, index, title) {
if (index > 0 && index + match.length !== title.length &&
match.search(smallWords) > -1 && title.charAt(index - 2) !== ":" &&
(title.charAt(index + match.length) !== '-' || title.charAt(index - 1) === '-') &&
title.charAt(index - 1).search(/[^\s-]/) < 0) {
return match.toLowerCase();
}
if (match.substr(1).search(/[A-Z]|\../) > -1) {
return match;
}
return match.charAt(0).toUpperCase() + match.substr(1);
});
}
});
