在WooCommerce的jQuery datepicker问题中禁用工作日和假日

Question

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，但它只是让datepicker消失，即使我尝试将脚本排队。 此代码是根据以下答案自定义的：

是否可以使jQuery UI Datepicker禁用星期六和星期日（和假期）？

下面是我在我的php中排队的delivery-date.js的代码。

  /*==================================================== 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; } } }); 

我想在这个答案代码中合并它：
WooCommerce checkout的时间循环从日期选择器输入字段中选择选项

但它不起作用。

你的阵列安静的不同于：
是否可以使jQuery UI Datepicker禁用星期六和星期日（和假期）？

要在Wordpress / Woocommerce中使用自定义数组，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',
    });
});

这只适用于您的自定义数组，并且正确显示了jQuery-ui datepicker 。

要将其合并到我的其他答案代码中，您将以这种方式使用它：

 // 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

    );

    // Making the delivery hour slots <option> arrays for Javascript
    for($i = $start_time; $i <= $end_time; $i += 1800 ){ // 1800 seconds is half an hour
