使用jquery进行日期比较

Question

我使用以下代码检查日期是否在今天之前！但是当我今天选择时，条件变为真实！

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;
}

我在这里做错了什么？

Answer 1

应该像

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;
}
