jQuery Title Case

You can use css, like:

.className 
{
    text-transform:capitalize;
}

This capitalizes the first letter. You can read more here

You don't need jQuery for this; it can be accomplished using the native .replace() method:

function toTitleCase(str) {
    return str.replace(/(?:^|\s)\w/g, function(match) {
        return match.toUpperCase();
    });
}

alert(toTitleCase("foo bar baz")); // alerts "Foo Bar Baz"
