With JQuery you can do this in the .change event, this event fires when the value of an element changes . In this event it can be checked whether textarea is empty, if it is, we put a default value.

$('#text1').change(function(){
    if( $("#text1").val().length < 1){
        $('#text1').val('Valor padrão');
      }
});

For versions prior to IE9 this can be done through the onpropertychange .

$('#text1').bind('input propertychange', function() {
    if( $("#text1").val().length < 1){
        $('#text1').val('Valor padrão');
      }
});
