如何在服务器中处理用于发布目的的日期

ko.bindingHandlers.datepicker = {
  init: function(element, valueAccessor, allBindingsAccessor) {
    var options = allBindingsAccessor().datepickerOptions || {},
        $el = $(element);

    //initialize datepicker with some optional options
    $el.datepicker(options);

    //handle the field changing
    ko.utils.registerEventHandler(element, "change", function() {
      var observable = valueAccessor();
      observable(moment($el.datepicker("getDate"))); // I added moment function here
    });

    //handle disposal (if KO removes by the template binding)
    ko.utils.domNodeDisposal.addDisposeCallback(element, function() {
      $el.datepicker("destroy");
    });

  }
  /*,
    update: function(element, valueAccessor) {
      var value = ko.utils.unwrapObservable(valueAccessor()),
        $el = $(element),
        current = $el.datepicker("getDate");

      if (value - current !== 0) {
        $el.datepicker("setDate", value);
      }
    }*/
};
  
var vm = {
  sampleDate: ko.observable(moment('/Date(1446393600000)/')), // I added moment function here
  originalValue: '/Date(1446393600000)/', // For reference only
  FromSqlDb: '2015-11-02' // For reference only

vm.formattedDate = ko.pureComputed(function() {
  return this.sampleDate() ? 
    this.sampleDate().format("ddd, DD MMM YYYY") :
  '';
}, vm);
 

ko.applyBindings(vm);
