IsValid

Validates the incoming value against the given type.

If the type is a range, the value is validated against the range. If the type is a pattern, the value is validated against the pattern. If the type is a date, the value is validated against the date format. If the type is a locale date, the value is validated against the locale date format. If the type is a regular expression, the value is validated against the regular expression.

Note we expressly do not support the `eurodate` type, since date formats vary across EU countries. For this, prefer the `LSIsDate( date, locale )` method instead.

Method Signature

IsValid(type=[string], value=[any], min=[any], max=[any], pattern=[any])

Arguments

Argument	Type	Required	Description	Default
type	string	true	The type to validate the value against
value	any	true	Value to test for validaty on a given type
min	any	false	The minimum value for the range type or a pattern to validate the value against

Examples

Check to see if a 235 is an integer

Use the isValid function with integer as the type.
