(JavaScript) JavaScript isNumeric function - CommissarXiii

Thu, 07 Apr 2011 08:30:18 GMT

The (input - 0) expression forces javascript to do type coercion on your input value; it must first be interpreted as a number for the boolean compare. If that conversion to a number fails, the expression will result in NaN. Then this numeric result is compared to the original value you passed in. Since the left hand side is a number, type coercion is again used. They should always be the same (always true), but there's a special rule that says NaN is never equal to NaN, and so a value that can't be converted to a number will always return false. The check on the length is of course for the empty string special case. In summary, if you want to know if a value can be converted to a number, actually try to convert it to a number.

(JavaScript) Force an input to be numeric with jQuery - BrunoDeBarros

This tiny jQuery plug in forces a user to enter only numeric values on an input field by silently removing non-numeric values as they're entered. (Caution: Never rely on client-side validation; use server-side validation as well)

(C#) Enum Limitation Fix Using a Generic Class and Implicit Casting - bryanlyman

Mon, 14 Dec 2009 18:03:38 GMT

For .net 2.0+ The one limitation to enumerations is revealed when you try to reverse lookup an enumeration value using Enum.Parse(). The parse function will return an inconsistent enum object if ever there are two or more enumerations with the same numeric value. This class fixes that problem. Written as a system extension and using implicit casting, the process has been made extremely easy and made the syntax for the parse function even simpler. The process even allows enumeration names starting with a number or the name of a C# keyword as long as the name is preceded by an underscore. The implicit cast from an Enum object to a Enum.Cast object has been deliberately left out to account for single directional assignment, which forces the class to be used properly. An Enum to Cast object lookup would defeat the whole purpose of the class if the implicit operator is used during runtime; for this purpose a user assignment operator of type String is supplied. This simply forces the user to use Cast = Enum.ToString() to parse to a correct object. The ToString() overload for a Cast object returns a Friendly name which replaces all underscores with spaces and even allows double underscores for commas and triple underscores for periods; for this reason, the implicit \"from string\" caster also converts from a friendly name to the proper Enum object. This makes it very handy for enumerating through a list of items for a combo or list box and converting back to the proper object by simply supplying the name of the list item.
