【问题描述】：

我有一个使用 jQuery-ui datepicker 的自定义 woocommerce 过滤器功能。我想使用下面的代码自定义选项，但它只会使日期选择器消失，即使我尝试将脚本排入队列也是如此。此代码是根据此答案定制的：

Can the jQuery UI Datepicker be made to disable Saturdays and Sundays (and holidays)?

下面是delivery-date.js的代码，我也在下面的php中排队。

  /*====================================================
      Delivery date Code
      Only two weeks booking time allowed.
      Diallowed days Sunday = 0, Saturday = 6
    Dates Disallowed by m/d - 1,1 | 1,26 | 2,16 | 3,8 | 4,14 | 4, 16 | 4,17 | 5,1 | 6,3 | 6,9 | 10,9 | 12,25 | 12, 26
  =====================================================*/
  jQuery(function($) 
      $('#datepicker').datepicker(
      maxDate: '+2W', 
      beforeShowDay: noWeekendsOrHolidays
    ); 

    var natDays = [ [1,1], [1,26], [2,16], [3,8], [4,14], [4, 16], [4,17], [5,1], [6,3], [6,9], [10,9], [12,25], [12, 26] ];

    function nationalDays(date) 
      for (i = 0; i < natDays.length; i++)
        if (date.getMonth() == natDays[i][0] - 1
          && date.getDate() == natDays[i][1]) 
          return [false, natDays[i][2] + '_day'];
        
      
      return [true, ''];
    

    function noWeekendsOrHolidays(date) 
      var noWeekend = $.datepicker.noWeekends(date);
      if (noWeekend[0]) 
        return nationalDays(date);
       else 
        return noWeekend;
      
    
  );

我正在尝试在这个答案代码中合并：Time loop for WooCommerce checkout select option from date picker input field

但它不起作用。

【参考方案1】：

您的阵列与以下中使用的阵列不同：Can the jQuery UI Datepicker be made to disable Saturdays and Sundays (and holidays)?

要使其与您在 Wordpress / Woocommerce 中的自定义数组一起使用，您需要进行一些更改。在下面的代码中，我将 2 个 javascript 函数合并为一个：

jQuery(function($)
    var natDays = [ [1,1], [1,26], [2,16], [3,8], [4,14], [4, 16],
        [4,17], [5,1], [6,3], [6,9], [10,9], [12,25], [12, 26] ]; // Holidays

    // No weekends and no holidays
    function noWeekendAndHolidays(date) 
        // No Holidays
        var nationalDays = [];
        for (i = 0; i < natDays.length; i++)
            if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == natDays[i][1]) 
                nationalDays = [false, ''];
                return false; // stop the loop
            
        if( ! nationalDays[0] )
            nationalDays = [true, ''];

        // No weekends (or no holidays)
        var noWeekend = $.datepicker.noWeekends(date);
        if (noWeekend[0])
            return nationalDays;
        else
            return noWeekend;
    

    // Jquery-ui datepicker
    $("#datepicker").datepicker(
        beforeShowDay: noWeekendAndHolidays,
        maxDate: '+2W',
    );
);

这仅适用于您的自定义数组，并且 jQuery-ui 日期选择器 正确显示。

要将其合并到 my other answer code 中，您可以这样：

 // Enable available jQuery datepicker script in Wordpress
add_action( 'wp_enqueue_scripts', 'enabling_date_picker' );
function enabling_date_picker() 

    // Only on front-end and checkout page
    if( is_admin() || ! is_checkout() ) return;

    // Load available datepicker jQuery-ui plugin script
    wp_enqueue_script( 'jquery-ui-datepicker' );


// Add and display custom checkout fields + jQuery script
add_filter( 'woocommerce_checkout_fields' , 'brown_remove_billing_postcode_checkout' );
function brown_remove_billing_postcode_checkout( $fields ) 
    // Your Settings
    $start_hour = 11; // start time (in hours)
    $end_hour = 16; // end time (in hours)
    $offset = 1; // One hour before slot time (can be a float number like 1.5
    // date_default_timezone_set ('Africa/Kampala'); // The timezone
    date_default_timezone_set('Australia/Brisbane');

    // Initializing variables
    $hour = 3600; // 1 hour in seconds
    $day = $hour * 24; // 1 day in seconds
    $now = strtotime("now"); // Now time
    $real_now = $now + ($offset * $hour); // Now time + offset
    $today_date = date("Y-m-d"); // today date
    $tomorrow_date = date("Y-m-d", strtotime("+1 day")); // tomorow date
    $today_time = strtotime($today_date); // Today time at 00:00 in seconds
    $tomorrow_time = strtotime($tomorrow_date); // Tomorrow time at 00:00 in seconds
    $start_time = $today_time + ( $start_hour * $hour ); // Start datetime in seconds
    $end_time = $today_time + ( $end_hour * $hour ); // End datetime in seconds
    $today_slots = $default_slots = $option_days = array();

    // Add Delivery day field (with jquery-ui datepicker enabled)

        'type'         => 'select',
        'options'      => array( '' => __('Select time for your delivery') ),
    );

    // Making the delivery hour slots <option> arrays for Javascript
    for($i = $start_time; $i <= $end_time; $i += 1800 ) // 1800 seconds is half an hour
        $key     = date('H:i', $i);
        $value   = date('h:ia', $i);

        // Today available hour slots array
        if($real_now < $i)
            $today_slots[$key] = $value;

        // Default hour slots array
        $default_slots[$key] = $value;
    

    // The correct start date and time (today or tomorow) for Javascript
    $date = $real_now < $end_time ? $today_date : $tomorrow_date;
    $dtime = $real_now < $end_time ? date("Y-m-d\TH:i:s", $today_time) : date("Y-m-d\TH:i:s", $tomorrow_time);
