Get the timestamp for 30 days from now: 获取30天后的时间戳：
var timestamp = new Date().getTime() + (30 * 24 * 60 * 60 * 1000)
// day hour min sec msec
Compare that timestamp with the timestamp for the selected date. 将该时间戳与所选日期的时间戳进行比较。
if (timestamp > selectedTimestamp) {
// The selected time is less than 30 days from now
}
else if (timestamp < selectedTimestamp) {
// The selected time is more than 30 days from now
}
else {
// -Exact- same timestamps.
}

Try this: 试试这个：

var date = $(this).datepicker('getDate');
var today = new Date();
if((new Date(today.getFullYear(), today.getMonth(), today.getDate()+30))>date)
{
