Javascript 查询 SharePoint 日期列返回 '/Date(1494460800000)/'

Question

我有一些 JavaScript 正在查询 SharePoint 日期列。格式为:DD/MM/YYYY，结果正常返回，但设备详细信息下返回的日期除外。

我正在尝试使用 Moment.js 库对其进行格式化，但我没有任何运气。 我认为是这一行:

var LifeCycleStart = item.DeviceAvailableFrom;

或者这一行我需要在以下位置使用 Moment 格式:

$('#devicedetails').append($(txtTitle)); 

完整代码如下:

function getDeviceDetails() {
  var txtTitle = "";
  var txtOverview = "";
  var txtAccessories = "";
  var txtDevicetype = "";
  var txtTypicalDeviceUsage ="";
  var txtKnownSystemIssues ="";
  var txtLifeCycles = "";
  var tempLCS2 = "";

  var query = "http://collaboration-dev.xxx.com/sites/it/SystemInventory/_vti_bin/listdata.svc/Devices?$expand=LifeCycleStatus&$filter=Id eq " + window.DeviceId + "";
  var call = $.ajax({
    url: query,
    type: "GET",
    dataType: "json",
    headers: {
      Accept: "application/json;odata=verbose"
    }       
  });
  call.done(function (data,textStatus, jqXHR){
    $.each(data.d.results, function(index, item) {
      var tempID = item.Id;
      var tempTitle = item.Title;

      var LifeCycleStart = item.DeviceAvailableFrom;
      var LifeCycleStatus = item.LifeCycleStatusValue;
      var DeviceOverView = item.Description;
      var AccessDetails = item.Accessories;
      var DeviceKind = item.Devicetype;
      var Usage = item.TypicalUsage;
      //var KnownSystem = item.KnownSystemIssues

      txtTitle = "<p>" + LifeCycleStart + "</p>       <p>" + 
        LifeCycleStatus + "</p>";
        txtOverview = "<p>" + DeviceOverView + "</p>";
        txtAccessories = "<p>" + AccessDetails + "</p>";  
        txtDevicetype = "<p>" + DeviceKind  + "</p>";
        txtTypicalDeviceUsage = "<p>" + Usage + "</p>"; 
    });

    $('#devicedetails').append($(txtTitle));  
    $('#deviceoverview').append($(txtOverview));
    $('#devicekind').append(txtDevicetype);
    $('#deviceacc').append(txtAccessories);
    $('#deviceuse').append(txtTypicalDeviceUsage);

  });

  call.fail(function (jqXHR,textStatus,errorThrown){
    alert("Error retrieving data: " + jqXHR.responseText);
  });
}

Momentjs 可以解析像 '/Date(1494460800000)/' 这样的字符串，如 ASP.NET JSON Date 中所述解析文档的一部分。

在您的情况下，您可以执行以下操作:

var LifeCycleStart = moment(item.DeviceAvailableFrom).format('DD/MM/YYYY');

使用 format将 moment 对象转换为字符串。
