【解决方案1】：

基本上，您可以使用beforeShowDay 函数，该函数为datepicker 上显示的每个日期调用。这已经是一个很好的答案，其中包含更多详细信息以及如何使用它：JQuery DatePicker and beforeShowDay

var today = new Date(Date.now()), yesterday = new Date(today - 24 * 60 * 60 * 1000);

function sameDate(a, b){
  return a.getDate() == b.getDate() && a.getMonth() == b.getMonth() && a.getFullYear() == b.getFullYear();
}

$(document).on("pagecreate", "#daily", function() {
    $("#datepicker").datepicker({
      beforeShowDay: function() {
          return [sameDate(date, today) || sameDate(date, yesterday), "",""];
      }
    });
});

顺便说一句，如果您只需要启用两个日期，为什么不使用带有两个单选按钮的漂亮fieldset？

var today = new Date(Date.now());
var yesterday = new Date(today - 24 * 60 * 60 * 1000);

function formatDate(date) {
  var dd = date.getDate();
  var mm = date.getMonth() + 1;
  var yyyy = date.getFullYear();
  return yyyy + "-" + mm + "-" + dd;
}

$(document).on("pagecreate", "#page-1", function() {
  $("#radio-choice-date-today").prop("value", formatDate(today));
  $("#radio-choice-date-yesterday").prop("value", formatDate(yesterday));
  $("#date-choiche").html($("#radio-choice-date-today").val());
  $("input[name*=radio-choice-date]").click(function() {
    $("input[name*=radio-choice-date]:checked").each(function() {
      $("#date-choiche").html($(this).val());
    });
  });
});

除此之外，这里是由 Salman Arshad 为 jQuery Mobile 设计的 datepicker 的完整示例，来源：jQuery UI Datepicker for jQuery Mobile

var today = new Date(Date.now());
var yesterday = new Date(today - 24 * 60 * 60 * 1000);

function sameDate(a, b){
  return a.getDate() == b.getDate() && a.getMonth() == b.getMonth() && a.getFullYear() == b.getFullYear();
}

function enableDate(date) {
  var enable = sameDate(date, today) || sameDate(date, yesterday);
  return [enable, "",""];
}

$(document).on("pagecreate", "#daily", function() {
    $("#datepicker").datepicker({
      beforeShowDay: enableDate
    });
});

编辑：

从您的代码看来，您需要本机方法，即 HTML5 input type="date"。在这种情况下，解决方案就更简单了：

var today = new Date(Date.now());
var yesterday = new Date(today - 24 * 60 * 60 * 1000);

function formatDate(date) {
  var dd = date.getDate();
  var mm = date.getMonth()+1;
  var yyyy = date.getFullYear();
  return yyyy + "-" + mm + "-" + dd;
}

$(document).ready(function() {
  $("#datepicker").prop("min", formatDate(yesterday));
  $("#datepicker").prop("max", formatDate(today));
  $('input[type="date"], input[type="datetime"], input[type="datetime-local"], input[type="month"], input[type="time"], input[type="week"]').each(function() {
    var el = this,
      type = $(el).attr('type');
    if ($(el).val() === '') $(el).attr('type', 'text');
    $(el).focus(function() {
      $(el).attr('type', type);
      el.click();
    });
    $(el).blur(function() {
      if ($(el).val() === '') $(el).attr('type', 'text');
    });
  });
});

...但是当前的浏览器实现并不总是完美的。兼容性和问题可以参考：Can I use... Date and time input types。
