Question

我有一个要求，我需要找到在文本字段中输入的日期不应小于当前日期，未来日期不应超过距离日期1年后的确切日期。我已经为前一个编码，但我后来要求我不能这样做。我在这里发布了用于检查少于当前日期的代码。如果输入的日期超过1年后的日期，请告诉我。

var currentDate = new Date();
var nextDate = new Date();

function checkLessThanCurrentDate() {
    //var dateEntered = arguments[0]; -->Will have date that come form textfield
    var day = dateEntered.split("/")[0];
    var month = dateEntered.split("/")[1];
    var year = dateEntered.split("/")[2];
    //--->Logic for chekcing date less than current date
    if ((year < currentDate.getFullYear() || (month - 1 < currentDate.getMonth() &&
    year <= currentDate.getFullYear()) || ((day < currentDate.getDate()) && (month -
    1 <= currentDate.getMonth()) &&
    (year <= currentDate.getFullYear())))) {
        return true;
    }

    else {
        return false;
    }
}

Answer 1

以下是如何从现在开始一年的日期：

var now = new Date();
var oneYear = new Date();
var oneYear.setYear(now.getFullYear() + 1);

if (dateEntered > oneYear) {
    // logic
}

Answer 2

我认为这应该适用于您的要求：

function isValidDate(dateToCheck)
{
    return isLessThanYearFromToday(dateToCheck) && dateToCheck >= new Date();
}

function isLessThanYearFromToday(dateToCheck)
{
    var yearFromToday = new Date();
    yearFromToday.setFullYear(yearFromToday.Year + 1);
    return dateToCheck <= yearFromToday;
}

Answer 3

您需要使用.getTime()方法。 .getTime() return the time in millisonds

var toDayDate = new Date();
var enteredDate = new Date('06/09/2015');      // mm/dd/yyyy formate

if(toDayDate.getTime()<enteredDate.getTime() && toDayDate.getTime()+(365*24*60*60*1000) > enteredDate.getTime()){
    alert();
}
