Objeto da data do Javascript

O objeto da data permite que voc� trabalhe programatically com datas e �pocas. Voc� cr�a um objeto da data usando o construtor da data. O objeto da data contem 17 fun��es.

O objeto da data

A classe da data � usada armazenar e recuperar datas no Javascript. Para criar um objeto da data, n�s podemos usar as seguintes t�cnicas dadas o bellow.

new Date ( )

d = new Date ( );

new Date ( milissegundos )

Este cr�a um objeto novo da data com o valor da data representado pelo n�mero dos milissegundos.

d = new Date (..... );

new Date ( dateString )

d = new Date ( "month date, year" ); d = new Date ( "month date, year h:m:s" );

O certificado de Java fornece as seguintes fun��es de data e de hora. N�s usamos estas fun��es em nosso programm.
