Question

我有mm-dd-YYYY H：i日期格式，我想在所选日期时间内添加30分钟。

function SetEndDate(start_date){ // start_date = "05-25-2017 05:00"
        var duration     = '30';
        var end_date_tmp = new Date(start_date);

        end_date_tmp.setMinutes(duration);
        $('#end_date').val(end_date_tmp);
}

它提供无效日期错误。

由于您的图书馆使用自定义格式（“05-25-2017 05:00”），我建议您尝试fecha library。它通过浏览器正确处理解析/格式化。

function GetEndDate(start_date){ // start_date = "05-25-2017 05:00"
    var duration = 30;
    var d = fecha.parse(start_date, 'MM-DD-YYYY HH:mm');

    d.setMinutes(d.getMinutes() + duration);
    return fecha.format(d, 'MM-DD-YYYY HH:mm');;
}

console.log(GetEndDate('05-25-2017 05:00'));
//Call it like so:
//$('#end_date').val(GetEndDate(/* Your variable here */));

试试这样：

var newDateObj = new Date();
newDateObj.setTime(oldDateObj.getTime() + (30 * 60 * 1000));

像这样：

function SetEndDate(start_date)
{ // start_date = "05-25-2017 05:00"
        var end_date_tmp = new Date(start_date);
         end_date_tmp.setTime(start_date.getTime() + (30 * 60 * 1000));
}

function SetEndDate(start_date){ // start_date = "05-25-2017 05:00" (mm-dd-yyyy) format
var duration        = '30';

var my_date_format  = function(start_date){
    var d           = new Date(Date.parse(start_date.replace(/-/g, "/")));
    var month       = ['01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12'];
    var date        = d.getFullYear() + "-" + month[d.getMonth()] + "-" + d.getDate();
    var time        = d.getHours()+":"+d.getMinutes();
    var date_time   = date + " " + time;
    return (date_time);  
};

var date_time   = my_date_format(start_date);
    d2              = new Date ( date_time );
    d2.setTime(d2.getTime() + (duration * 60 * 1000));

var date_new    = new Date(d2);
    yr              = date_new.getFullYear();
    month           = date_new.getMonth() < 10 ? '0' + (date_new.getMonth() + 1)  : (date_new.getMonth() + 1);
    day             = date_new.getDate()  < 10 ? '0' + date_new.getDate()  : date_new.getDate();
    minutes         = date_new.getMinutes()  < 10 ? '0' + date_new.getMinutes()  : date_new.getMinutes();
    hours           = date_new.getHours()  < 10 ? '0' + date_new.getHours()  : date_new.getHours();
    time            = hours + ":" + minutes;
    newDate         = month + '-' + day + '-' + yr + ' ' + time;
$('#end_date').val(newDate); // you can get new date in "newDate" variable
}

如何在Jquery的Date Time中添加30分钟？
