使用jQuery進行日期比較

Question

我使用以下代碼檢查日期是否在今天之前！ 但是當我今天選擇時，條件變為真！

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;
}

我在這里做錯了什么？

Answer 1

應該是這樣的

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;
}
