使用jQuery进行日期比较

Question

I use the following code to check the date is before today! But when I select today, the condition becomes true!

var fromDate = $('#from').datepicker('getDate');
var toDate = $('#to').datepicker('getDate');
var today = new Date();

if(today >= fromDate || toDate <= today){
    alert('Cannot book dates prior to today.');
    $('#from, #to').val('')
    return false;
}

What am I doing wrong here?

Answer 1

Should be something like

var fromDate = $('#from').datepicker('getDate');
var toDate = $('#to').datepicker('getDate');
var today = new Date();
 today.setHours(0,0,0,0);
fromDate.setHours(0,0,0,0);
toDate.setHours(0,0,0,0);

if(today > fromDate || toDate < today){
    alert('Cannot book dates prior to today.');
    $('#from, #to').val('')
    return false;
}
