Well, a number by definition can't have spaces in it. So if there ARE spaces, then it's a string, and can be treated as such.
Alternately I suppose you could try multiplying the value by 1 and see what you get. andy -----Original Message----- From: jquery-en@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of africanshox Sent: Tuesday, September 16, 2008 9:39 AM To: jQuery (English) Subject: [jQuery] Checking if input is a number. i have a serach box that checks for a product code or product keyword. I need to find out how i can check if the input submitted on this search box is a number, and if it is, remove any white spaces. The reason is that product codes coming from a feed have a space in them and it is much easier if i sue jquery rather than go through a collection fo nearly 20,000 codes. can anyone point me in the right direction?
