我试图计算JavaScript中两个日期对象之间的日期差异。但是,当我尝试使用Math.round
函数时,我得到NaN
。
此问题出现在此行
var deliveryDays = Math.round(Math.abs((currentDate.getTime() - basketDate.getTime())/(oneDay)));
请参阅以下代码:
function datePicker() {
$('#datePicker').datepicker();
$('.ui-datepicker').addClass('datePicker'); //This is added to the class ui-datepicker which is generated when the date picker is generated.
var currentDate = $.datepicker.formatDate('dd-mm-yy', new Date()); // Get today's date.
currentDate = new Date(currentDate); // Convert string to date (string must be an appropriate format.
$("#datePickerConfirmation").click(function () {
var basketDate = $('#datePicker').datepicker('getDate');
basketDate = $.datepicker.formatDate('dd-mm-yy', new Date(basketDate)); // Changes the date format to dd-mm-yyyy.
basketDate = new Date(basketDate);
// This block works out the difference between the current date and the selected date.
var oneDay = 24 * 60 * 60 * 1000;
var deliveryDays = Math.round(Math.abs((currentDate.getTime() - basketDate.getTime()) / (oneDay)));
basketDate = basketDate.toString();
currentDate = currentDate.toString();
deliveryDays = deliveryDays;
var result = window.confirm('Confirm Date: ' + basketDate + '\n \nDays to Delivery: ' + deliveryDays);
if (result == true) {
console.log("User pressed Ok / Confirm Date set to: " + basketDate);
// Do nothing
} else {
console.log("User pressed Cancel, basket set to null");
basketDate = null;
console.log(basketDate);
}
});
}

您无需将日期转换为字符串,然后再转换为日期。替换这些行
var currentDate = $.datepicker.formatDate('dd-mm-yy', new Date()); // Get today's date.
currentDate = new Date(currentDate);
用这个
var currentDate = new Date();
以及这些行
basketDate = $.datepicker.formatDate('dd-mm-yy', new Date(basketDate)); // Changes the date format to dd-mm-yyyy.
basketDate = new Date(basketDate);
用这个
basketDate = new Date(basketDate);
