Opencv在内存中的Mat表示(Opencv in memory Mat representation)

 您可以使用changeDate事件，因为文档说： 
 
 
 
 所有事件都有附加到传递给任何事件处理程序的事件对象的额外数据 
 
 
 
  
 date ：在本地时区中的相关日期对象。 对于多日期选择器，这将是最近挑选的日期。 
 
 
 
 
 您可以检查所选日期（使用getFullYear() ，如getDate() ， getMonth()和getFullYear() ）以及使用jQuery show()和hide() 。 
 
 这里有一个实况样本： 
 
 
 
 
 
  
$(function() {
  $('#myCalendar').datepicker({
    format: 'mm-dd-yyyy',
    weekStart: 1,
    maxViewMode: 2,
    todayBtn: "linked",
    daysOfWeekHighlighted: "0,6",
    todayHighlight: true
  }).on('changeDate', function(e) {
    if( e.date && e.date.getDate() == 7 &&
        e.date.getMonth() == 10 && 
        e.date.getFullYear() == 2017 ){
      $("#example").show();
    } else {
      $("#example").hide();
    }
    $('#hiddenInput').val(
      $('#myCalendar').datepicker('getFormattedDate')
    );
  });
});
 
  
#example {
  display: none;
  color: green;
  font-weight: bold;
}

You can use changeDate event, as the docs says:
 
 
 
All events have extra data attached to the event object that is passed to any event handlers
 
 
 
  
date: the relevant Date object, in local timezone. For a multidate picker, this will be the latest date picked.
 
 
 
 
You can check what is the selected day (using setter like getDate(), getMonth() and getFullYear()) and the using jQuery show() and hide().
 
Here a live sample:
 
 
 
 
 
  
$(function() {
  $('#myCalendar').datepicker({
    format: 'mm-dd-yyyy',
    weekStart: 1,
    maxViewMode: 2,
    todayBtn: "linked",
    daysOfWeekHighlighted: "0,6",
    todayHighlight: true
  }).on('changeDate', function(e) {
    if( e.date && e.date.getDate() == 7 &&
        e.date.getMonth() == 10 && 
        e.date.getFullYear() == 2017 ){
      $("#example").show();
    } else {
      $("#example").hide();
    }
    $('#hiddenInput').val(
      $('#myCalendar').datepicker('getFormattedDate')
    );
  });
});
 
  
#example {
  display: none;
  color: green;
  font-weight: bold;
}
