我有一个datepicker输入和一个timepicker输入,我想用它来安排一个人约会.

当用户点击输入以打开datepicker菜单时,我想使特定的日期时间变灰.我有一个php函数,以’Y-m-d H：i：s’字符串格式返回此日期时间数组.但我不知道如何使用该函数的返回值来为javascript函数提供在datepicker中禁用一系列日期所需的功能.

在我的datepicker的onSelect事件中,我希望它根据当天预订的时隙来启用/禁用我的timepicker中的时间选项.但我不知道怎么做.

我确实找到了如何在timepicker Here中禁用时间范围.代码示例如下：

$('input.timepicker').timepicker({
    'disableTimeRanges': [
        ['1am', '2am'],
        ['3am', '4:01am']
    ]
});

但这就是我如何禁用时间戳范围内的时间范围.我不知道如何在datepicker的BeforeShowDay中禁用它们？

<script type="text/javascript">   
    $(document).ready(function(){
        $( "#datepickerListAppointments" ).datepicker(
        {
            minDate:'0',
            beforeShowDay:
            function(dt)
            {   // need to disable days other than tuesday and wednesday too.
                return [dt.getDay() === 2 || dt.getDay() === 3, ""];
            },
            onSelect : function(){
                should disable/enable timepicker times from here?
            }
        });

        $('input.timepicker').timepicker({
            timeFormat: 'h:mm p',
            interval: 90,
            minTime: '9',
            maxTime: '10:30am',
            defaultTime: '9',
            startTime: '9:00',
            dynamic: false,
            dropdown: true,
            scrollbar: false                
        });

    });

这是提供日期时间的函数,以防有助于了解.

function get_next_open_appointments($numAppointments, $timeSlotToExclude = "")
{
    global $db;
    $whereCondition = "WHERE FirstName = :null ";
    if ($timeSlotToExclude != "")
    {
        $whereCondition .= "AND AppointmentTime != '$timeSlotToExclude' ";
    }

    $query = "SELECT DISTINCT AppointmentTime FROM appointments
              $whereCondition
              ORDER BY AppointmentTime ASC LIMIT $numAppointments";
    $statement = $db->prepare($query);
    $statement->bindValue(':null', "");
    $statement->execute();
    $datesArray = array();
    while ($row = $statement->fetch()) 
    {
        array_push($datesArray, $row['AppointmentTime']);
    }
    $statement->closeCursor();
    return $datesArray;
}

更新：

雨果德卡尔莫指出我正确的方向,我得到适当的禁用/启用日期.但是,我不知道如何使用我在下面的代码中提取的日期时间来禁用/启用timepicker中的时间.

这是新代码：

<script type="text/javascript">   
    $(document).ready(function(){

        // uses php to get open appointments, and put them in a javascript array
        <?php $datetime_openings = get_next_open_appointments(200);
        $date_openings = array();
        foreach ($datetime_openings as $dt)
        {
            array_push($date_openings, substr($dt,0,10)); // just the date part
        }

        $json_date_openings = json_encode($date_openings);
        echo "var arr_Openings = ". $json_date_openings . ";\n";
        ?>

        $( "#datepickerOpenAppointments" ).datepicker(
        {
            minDate:'0',
            beforeShowDay:
            function(dt)
            {
                var string = jQuery.datepicker.formatDate('yy-mm-dd', dt);
                var bFound = (arr_Openings.indexOf(string) != -1);
                return [ bFound ]; 
            },
            onSelect : function(){
               //    Should disable/enable time ranges here?
        });

        $('input.timepicker').timepicker({
            timeFormat: 'h:mm p',
            interval: 90,
            minTime: '9',
            maxTime: '10:30am',
            defaultTime: '9',
            startTime: '9:00',
            dynamic: false,
            dropdown: true,
            scrollbar: false                
        });

    });

解决方法:

试试这个,
对不起,我没有使用beforeshowDay
选择日期2017-7-14和2017-7-17并查看

var disabledDateTime = {
  '2017-7-14':[
  	['2:30am','3:00am'],
    ['6:30am','9:00am']
  ],
	'2017-7-17':[
  	['1:00am','3:00am'],
    ['5:30am','7:00am'],
    ['11:30am','2:00pm']
  ]
};

$(function() {
  $('#pickTime').timepicker();
  $('#pickDate').datepicker({
    'format': 'yyyy-m-d',
    'autoclose': true
  }).on('changeDate',function(e){
    var ts = new Date(e.date);
    var m = ts.getMonth()+1;
    var dt = ts.getFullYear() + '-' + m + '-' + ts.getDate();
    var opt = {'disableTimeRanges': []}
    if(typeof(disabledDateTime[dt])!='undefined'){
      $('#pickTime').timepicker('setTime', '');
      opt = {'disableTimeRanges': disabledDateTime[dt]}
    }
    $('#pickTime').timepicker('option',opt);
  });
});
