var today = new Date();
var myToday = new Date(today.getFullYear(), today.getMonth(), today.getDate(), 0, 0, 0);

According to MDNthe setHoursfunction actually takes additional optional parameters to set both minutes, seconds and milliseconds. Hence we may simply write
根据MDN，该setHours函数实际上需要额外的可选参数来设置分钟、秒和毫秒。因此我们可以简单地写
// dateString is for example "Fri, 26 Sep 2014 18:30:00 GMT"
function getFormattedDate(dateString) {
var date = new Date(dateString);
date.setHours(0, 0, 0); // Set hours, minutes and seconds
return date.toString();
}
