//*** 
//* Descrição.: formata um campo do formulário de 
//* acordo com a máscara informada... 
//* Parâmetros: - objForm (o Objeto Form) 
//* - strField (string contendo o nome 
//* do textbox) 
//* - sMask (mascara que define o 
//* formato que o dado será apresentado, 
//* usando o algarismo "9" para 
//* definir números e o símbolo "!" para 
//* qualquer caracter... 
//* - evtKeyPress (evento) 
//* Uso.......: <input type="textbox" 
//* name="xxx"..... 
//* onkeypress="return txtBoxFormat(document.rcfDownload, 'str_cep', '99999-999', event);" 
//* Observação: As máscaras podem ser representadas como os exemplos abaixo: 
//* CEP -> 99.999-999 
//* CPF -> 999.999.999-99 
//* CNPJ -> 99.999.999/9999-99 
//* Data -> 99/99/9999 
//* Tel Resid -> (99) 999-9999 
//* Tel Cel -> (99) 9999-9999 
//* Processo -> 99.999999999/999-99 
//* C/C -> 999999-! 
//* E por aí vai... 
//* Exemplo usado no site do jetvoip
//* <input name="tx_de" type="text" class="tag001" id="tx_de" onkeypress="return txtBoxFormat(document.form1, 'tx_de', '99/99/9999', event);" size="12" maxlength="10">
