jQuery validation engine, jquery inline form validation

jQuery validation engine, yet another nice form validation plugin for jquery javascript framework, comes with language localization supported and many predefined validation rules:

• optional: Special: Only validate when the field is not empty
• required: Field is required
• length[0,100] : Between x and x characters allowed
• minCheckbox[7] : Set the maximum checkbox autorized for a group
• confirm[fieldID] : Match the other field (ie:confirm password)
• telephone : Match telephone regEx rule.
• email : Match email regEx rule.
• onlyNumber : Numbers only
• noSpecialCaracters : No special characters allowed
• onlyLetter : Letters only
• date : Invalid date, must be in YYYY-MM-DD format

but you also could define a custom validation rule i.e:

"telephone":{
"regex":"/^[0-9-()]+$/",
"alertText":"* Invalid phone number"},
