javascript - 无法在 mvc 获取 Controller 方法(来自 Uri())中从 QueryString 获取 DATETIME

Question

 This is the query string that I am receiving in URL.

 Output url: /demo/analysis/test?startDate=Sat+Jun+01+2013+00%3A00%3A00+GMT-0700+(Pacific+Daylight+Time)&endDate=Fri+Sep+13+2013+00%3A00%3A00+GMT-0700+(Pacific+Daylight+Time)

 test controller:
 Public Function GetData(<FromUri()> ByVal query As Request) As HttpResponseMessage
 {
 }

 Request{
 public DateTime StartDate { get; set; }
 public DateTime EndDate { get; set; }
 }

Angularjs API 代码:

   exportFunt = function () {
            var query = generateExportData();
            Export(query);
        };


    function generateExportData() {
             return {
               startDate: viewModel.StartDate,
               endDate: viewModel.EndDate,
            };
        }

     Export: function (query) {

                $window.open('/demo/analysis/test?$.param(query), '_blank');
            }

由于您不需要时间，我假设您从某种日期选择器中选择整个日历日期。只需将您的日期作为 yyyy-mm-dd 格式的字符串传递即可:

function pad(n) {
  return n < 10 ? '0' + n : n;
}

function getDateString(dt) {
  return [dt.getFullYear(),pad(dt.getMonth()+1),pad(dt.getDate())].join('-');
}

function generateExportData() {
    return {
        startDate: getDateString(viewModel.StartDate),
        endDate: getDateString(viewModel.EndDate)
    };
}

或者如果您不想自己编写所有这些，您可以考虑使用优秀的 moment.js图书馆:

function generateExportData() {
    return {
        startDate: moment(viewModel.StartDate).format('YYYY-MM-DD'),
        endDate: moment(viewModel.EndDate).format('YYYY-MM-DD')
    };
}
