我正在尝试根据用户名字段的更改动态更改 pikaday 日期选择器中允许的月份中的哪些日期。即使用类似下面的东西来禁用除每个月的第一天以外的所有内容。但是选择器不起作用。我尝试了许多变体。有任何想法吗？

$("#username").on('change', function() { 
 if(.........){
   $('.pika-button :not([value="1"])').prop("disabled", true);
 }
});

如果有帮助，这是其中之一的内部 html：

<button class="pika-button pika-day" type="button" data-pika-year="2018" data-pika-month="11" data-pika-day="1">1</button>

提前致谢

$(function() {

  $("#username").on('change', '.buttonWrapper', function() {
    $('.pika-button:not([data-pika-day=1])').prop('disabled', true);
  });

});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>

<body>
  <div class="buttonWrapper">
    <button class="pika-button pika-day" type="button" data-pika-year="2018" data-pika-month="1" data-pika-day="1">Month=1, Day=1</button>
    <button class="pika-button pika-day" type="button" data-pika-year="2018" data-pika-month="5" data-pika-day="1">Month=5, Day=5</button>
    <button class="pika-button pika-day" type="button" data-pika-year="2018" data-pika-month="2" data-pika-day="2">Month=2, Day=2</button>
    <button class="pika-button pika-day" type="button" data-pika-year="2018" data-pika-month="3" data-pika-day="4">Month=3, Day=4</button>
