Reset to default 7You can always do this if str is your string:
var digits = str.replace(/\D/g, ""),
letters = str.replace(/[^a-z]/gi, "");
Essentially, what this code does is replace all of the characters that you do not want with the empty string.
\D and [^a-z] are character classes that represent, respectively, all the non-digits and all the non-letters. The g at the end of the two expressions makes them replace all occurrences of the pattern. The i make it case-insensitive, keeping both lower and upper case letters.
Well for the example you gave I would try
parseInt(num)
so if you had parseInt(12Jan);
you should get 12.
I am not an expert so I hope this helps.
