推荐答案

你可以解析初始日期，将其提供给日期对象，用当前时间减去它以获得毫秒差异，然后除以一天中的毫秒数。

You can parse the initial date, feed it to a date object, substract it with the current time to get a millisecond difference, and then divide it by the number of milliseconds in a day.

var checkindatestr = "28-07-2011";
var dateParts = checkindatestr.split("-");

var checkindate = new Date(dateParts[2], dateParts[1] - 1, dateParts[0]);
var now = new Date();
var difference = now - checkindate;
var days = difference / (1000*60*60*24);

alert(days);

在撰写本文时，这给出-7.5。这是一个负数，因为日期是将来。如果你想要一个正数，只需交换减法中的变量。如果你想要一个整数，只需使用Math.round。

At the time of writing this gives -7.5. It's a negative number because the date is in the future. If you want a positive number, just swap the variables in the substraction. If you want a round number, just use Math.round.
