更新了 jFiddle (http://jsfiddle.net/LGw6F/2230/)

$(document).ready(function(){
   $("#txtFromDate").datepicker({ 
    dateFormat: 'yy-mm-dd',
    changeMonth: true,
    minDate: new Date(),
    numberOfMonths: 2,
    onSelect: function(selected) {
          $("#txtToDate").datepicker("option","minDate",selected);
          var  selectedDate = $("#txtFromDate").datepicker("getDate");
          var msecsInADay = 5184000000;
          var endDate = new Date(selectedDate.getTime() + msecsInADay);
          $("#txtToDate").datepicker("option","maxDate",endDate);

        }
  });

  $("#txtToDate").datepicker({ 
      dateFormat: 'yy-mm-dd',
      numberOfMonths: 2,
  });
});

要预填充您的输入字段 ("put a default date")，请执行以下操作：

$(function(){
    $("#txtFromDate").datepicker({
        minDate:0,
        maxDate: "+60D",
        numberOfMonths: 2,
    });
    $("#txtToDate").datepicker({ 
        minDate:0,
        maxDate:"+60D",
        numberOfMonths: 2,
    });
    var default_date = new Date();
    default_date.setDate(default_date.getDate()+60);
    $('#txtFromDate').datepicker('setDate', new Date());
    $('#txtToDate').datepicker('setDate', default_date);
});
$("#txtFromDate").datepicker({
        onSelect: function(dateText) {
            $("#txtToDate").datepicker("option", "minDate", $('#txtFromDate').datepicker("getDate") );
            var date2 = $("#txtFromDate").datepicker("getDate");
            date2.setDate(date2.getDate()+60);
            $("#txtToDate").datepicker("option", "maxDate", date2);
        }
    });
