Tout Bon Nombre Sélecteur JQuery (ou Javascript)?

J'ai utilisé cette. Vous devriez être capable de le modifier pour ajouter des options supplémentaires telles que min et max assez facilement.

//Make a control only accept numeric input
//eg, $("#myedit").numeric()
// $("#myedit").numeric({alow: ' ,.'})
// $("#myedit").numeric({decimals: 2})
