• Positive integer "^[0-9][1-9][0-9]$"
• Non positive integer （ Negtive integer + 0）"^((-\d+)|(0+))$"
• Negtive integer "^-[0-9][1-9][0-9]$"
• Integers "^-?\d+$"
• Nonnegative floating point number （ Positive floating point + 0） "^\d+(.\d+)?$"
• Positive floating point "^(([0-9]+.[0-9][1-9][0-9])|([0-9][1-9][0-9].[0-9]+)|([0-9][1-9][0-9]))$"
• Non positive floating point number （ Negative floating point number + 0） "^((-\d+(.\d+)?)|(0+(.0+)?))$"
• Negative floating point number "^(-(([0-9]+.[0-9][1-9][0-9])|([0-9][1-9][0-9].[0-9]+)|([0-9][1-9][0-9])))$"
• Floating point numbers "^(-?\d+)(.\d+)?$"
• from 26 A string of English letters "^[A-Za-z]+$"

• from 26 A string of lowercase letters "^[a-z]+$"
• By numbers and 26 A string of English letters "^[A-Za-z0-9]+$"
• By digital 、26 A string of English letters or underscores "^\w+$"
• email Address "^[\w-]+(.[\w-]+)*@[\w-]+(.[\w-]+)+$"
• url "^[a-zA-z]+://(\w+(-\w+))(.(\w+(-\w+)))(\?\S)?$"
• year - month - Japan /^(d{2}|d{4})-((0([1-9]{1}))|(1[1|2]))-((0-2)|(3[0|1]))$/
• month / Japan / year /^((0([1-9]{1}))|(1[1|2]))/((0-2)|(3[0|1]))/(d{2}|d{4})$/
• Email "^([w-.]+)@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.)|(([w-]+.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(]?)$"
• Phone number "(d+-)?(d{4}-?d{7}|d{3}-?d{8}|^d{7,8})(-d+)?"
• IP Address "^(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5])$"
• YYYY-MM-DD Basically, leap years and 2 Month and so on have been taken into account ^((((1[6-9]|[2-9]\d)\d{2})-(0?[13578]|1[02])-(0?[1-9]|[12]\d|3[01]))|(((1[6-9]|[2-9]\d)\d{2})-(0?[13456789]|1[012])-(0?[1-9]|[12]\d|30))|(((1[6-9]|[2-9]\d)\d{2})-0?2-(0?[1-9]|1\d|2[0-8]))|(((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))-0?2-29-))$
