您可以使用onSelect事件

$(function() {
  $("#from").datepicker({
    defaultDate: "",
    maxDate: "+0d",
    changeMonth: false,
    numberOfMonths: 1,

    onSelect: function(selected) {
      $("#to").datepicker("option", "minDate", selected)
    }
  });

  $("#to").datepicker({
    defaultDate: "",
    maxDate: "+0d",
    changeMonth: false,
    numberOfMonths: 1,

    onSelect: function(selected) {
      $("#from").datepicker("option", "maxDate", selected)
    }
  });
});
