推荐答案

从现在开始获取30天的时间戳:

Get the timestamp for 30 days from now:

var timestamp = new Date().getTime() + (30 * 24 * 60 * 60 * 1000)
//                                      day hour  min  sec  msec

将该时间戳与所选日期的时间戳进行比较.

Compare that timestamp with the timestamp for the selected date.

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.
}
