MAXLENGTH EM TEXTAREA COM JQUERY
Hoje eu irei mostrar como limitar o tamanho de textareas com um simples código jquery.
Sabemos que inputs do tipo text tem a propriedade maxlength e também sabemos que textareas não tem, mas com um código jquery podemos trabalhar como se existisse maxlength em textareas.
Para fazermos isso é simples.
Precisamos de um textarea com maxlength.
<textareamaxlength="15"rows="5"cols="30"name="texto"></textarea>
Após devemos adicionar no seu javascript o seguinte código:
$("textarea[maxlength]").keypress(function(event){var key = event.which;//todas as teclas incluindo enterif(key >= 33 || key == 13) {var maxLength = $(this).attr("maxlength");var length = this.value.length;if(length >= maxLength) {event.preventDefault();}}});
