Question

这是我根据选择facode启用/禁用保存按钮的代码，但我遇到的问题是，当用户选择facode后重置表单时，会启用保存按钮。我想禁用那个

  $('#save').attr('disabled', 'disabled');
    $('#myCoolForm').attr('disabled', 'disabled');
    $(document).on('change','#facode,#rb_facode',function(){
        if (buttonsDisable($(this).val())) {
            $('#myCoolForm').attr('disabled', false);
            $('#save').attr('disabled', false);
        } else {
            $('#myCoolForm').attr('disabled', 'disabled');
            $('#save').attr('disabled', 'disabled');
        }
    });
    function buttonsDisable(e) {
        if (e > 0) {
            return true;
        } else {
            return false
        }
    }

请改用此方法：

$('#save').prop('disabled', true); // disabling the button

要启用按钮，请使用：

$('#save').prop('disabled', false); // enabling the button.
