Question

我必须将今天的日期与日历日期（使用日期选择器ajax的选择日期）进行比较。如果日期差异超过7天，则生成警报。

        var mydate = new Date();//Todays date
        var theyear = mydate.getFullYear();
        var themonth = mydate.getMonth() + 1;
        var thetoday = mydate.getDate();

        txtDate.value='04-Jul-2012';//date picker date in this format

Answer 1

var mydate = new Date(); //Todays date
txtDate.value='16-Jul-2012'; //date picker date in this format

var newDate = new Date(txtDate.value); //make date object

var difference = Math.ceil((newDate-mydate) / (60*60*24*1000)); //calculate days

if (difference > 7) alert('more than 7 days');

FIDDLE

Answer 2

var datePicked = '26-Jun-2012';
var datems = Date.parse(datePicked.replace(/-/g, " "));
var dateNow = new Date();
dateNow.setHours(0,0,0,0);
var msDiff = Math.abs(Number(dateNow) - datems);
// 7 Days = 604 800 000 ms
if(msDiff > 604800000) alert("Time difference greater 7 days");

将今天的日期与日历日期进行比较（接下来的七天只生成警报）
