Clear input on focus with jQuery and return on blur

Question

This almost works. However, when leaving the field \"defaulttext\" appears rather than the original text value. Not sure how to most efficiently echo the variable inside default

Answer 1

var q = $('#q');
q.focus(function() {
    if ($(this).attr('data-default') == $(this).val()) {
        $(this).val('');
    }
}).blur(function() {
    if($(this).val() == '') {
        $(this).val($(this).attr('data-default'));
    }
});
