Recuperar valor de un radio button con jQuery

Activado 2 Nov, 2012 Por Adolfo 37 Comentarios

Logotipo de jQuery.Muchas veces, desarrollando formularios en páginas dinámicas, necesitamos saber el valor para un grupo de radio buttons. Esto lo podemos conseguir de forma sencilla en jQuery utilizando la siguiente sintaxis:

  1. $("input[name='grupo radio button']:checked").val();

Con la anterior sentencia obtenemos el valor seleccionado de un grupo de radio buttons. Podemos utilizar el atributo name para poder utilizar el grupo de radio buttons de forma similar a otros campos.

  1. $("input[name='grupo radio button']").click(function(){
  2. 	//	Operaciones en la función.
  3. });
