如何更改 bootstrap Datepicker 中的日期格式？

Question

日期选择器代码如下：

$("#startDate").datepicker({
    autoclose:true,
    startView:"months",
    minViewMode:"months",
    orientation: "bottom",
    format: "dd-MM-yyyy"
}).on('changeDate', function(selected){
    startDate = new Date(selected.date.valueOf());
    startDate.setDate(startDate.getDate(new Date(selected.date.valueOf())));
    $('.to').datepicker('setStartDate', startDate);
});
$("#endDate").datepicker({
    autoclose:true,
    startView:"months",
    minViewMode:"months",
    orientation: "bottom",
    format: "dd-MM-yyyy"
}).on('changeDate', function(selected){
    FromEndDate = new Date(selected.date.valueOf());
    FromEndDate.setDate(FromEndDate.getDate(new Date(selected.date.valueOf())));
    $('.from').datepicker('setEndDate', FromEndDate);
});

我在前端得到的格式是：

01-January-2016

现在我需要格式为：

Jan 2016

在日期选择器（前端）框中，而 01-01-2016 在后端。我怎样才能做到这一点？请大家帮帮我。

如果您想将日期格式转换为任何格式，请使用此库。

Answer 2

您可以简单地使用 format 选项更改日期选择器（前端）格式，指定 M yyyy 而不是 dd-MM-yyyy。

然后就可以使用moment to convert your Date to a string using the format you need before sendind it to server. Here there is an example of converting date got from the datepicker to a string in the format DD-MMMM-YYYY using moment parsing function and moment format方法了。

$("#startDate").datepicker({
    autoclose:true,
    startView:"months",
    minViewMode:"months",
    orientation: "bottom",
    format: "M yyyy"
}).on('changeDate', function(selected){
    startDate = new Date(selected.date.valueOf());
    startDate.setDate(startDate.getDate(new Date(selected.date.valueOf())));
    $('.to').datepicker('setStartDate', startDate);
});
$("#endDate").datepicker({
    autoclose:true,
    startView:"months",
    minViewMode:"months",
    orientation: "bottom",
    format: "M yyyy"
}).on('changeDate', function(selected){
    FromEndDate = new Date(selected.date.valueOf());
    FromEndDate.setDate(FromEndDate.getDate(new Date(selected.date.valueOf())));
    $('.from').datepicker('setEndDate', FromEndDate);
});

$('#btnSend').click(function(){
    // Getting date from the picker
    var startDate = $("#startDate").datepicker('getDate');
    var endDate = $("#endDate").datepicker('getDate');
    // Convert date to string in the given format
    var startDateServer = moment(startDate).format('DD-MMMM-YYYY');
    var endDateServer = moment(endDate).format('DD-MMMM-YYYY');
    // You can send startDateServer and endDateServer string to the server
    console.log(startDateServer, endDateServer);
});
