regexp-javaScript的姓氏和名字

Question

I'm trying to make a JavaScript regexp such as the facebook uses for real names:

Names can't include:
• Symbols
• numbers
• unusual capitalization
• repeating characters or punctuation

source: Facebook help center
Here is my regexp:

 /^[a-z \,\.\'\-]+$/i

The problem with this regexp is that it doesn't check for repeated characters or punctuation:
then I found this :

/(.)\1/

so I'm now checking it like this:

$('input [type=text]).keyup(function(){
var name = $(this).val();
var myregex = /^[a-z\,\.\'\-]+$/i
var duplicate =  /(.)\1/
if(name != myregex.exec(name) ||  name == /(.)\1/)
{// the name entered is wrong
}
else
//the name is ok

but the problem I'm facing is with inputs like:

• Moore
• Callie
• Maggie

what can I do to get the problem solved?

You should stop trying to solve this problem:

• It is very complicated
• Names are very personal

For instance your system will never be able to validate names from China or Japan.... (For instance: Børre Ørevål ,汉/漢 )

So just leave the whole idea, and let people freely enter their names with no restrictions.
