garbageOUT is a JavaScript written years ago by csimmons.net to speed up the drudgery of writing code to validate data submitted via forms.

Validation is an essential part of creating robust, dependable web systems. Failure to account for potential input discrepancies can cause system errors, frustrate users, and worst of all compromise data.

Here are a few conditions garbageOUT can check for:

• Required fields
• Valid Email Addresses
• Alpha input only
• Numeric input only
• Number must be greater than X
