JQuery Datepicker应该只显示日期

我想在没有文字时间的情况下显示日期，但似乎即使我设置了datepicker的格式也没有用。而且我也不想在datepicker中显示Time。
请参阅下面的图片，我想删除黄色突出显示。

I want to display the date only without the time on the text , but it seems that it didn't work even I've set the format of the datepicker. And also I dont want to display the Time in the datepicker. Please see image below, I want to remove the yellow highlighted.

var defaultFormat = { dateFormat: 'mm/dd/yy' };
$.datepicker.setDefaults(defaultFormat);
$('#EM_Date').datetimepicker({
    showHour: false,
    showMinute: false
});
