我有一个带有单个date_popup字段的drupal表单。我希望仅在小时内提供12、15和17的选项。
$form['order-group']['delivery'] = array(
'#title' => t('I Need The Equipment Ready By'),
'#type' => 'date_popup',
'#date_format' => 'd-M-Y H:i',
'#timepicker' => 'timepicker',
'#timepicker_options' => array(
'rows' => 3,
'hours' => array(
'starts' => 12,
'ends' => 17,
),
'onHourShow' => 'onHourShowCallback',
'minutes' => array(
'starts' => 0,
'ends' => 0,
),
'showCloseButton' => TRUE,
'closeButtonText' => t('Close'),
),
'#default_value' => date('Y-m-d 12:00',time()),
'#date_label_position' => '',
);
然后我将以下内容添加到我的javascript文件中(该脚本前面的drupal_add_js随附)
function onHourShowCallback(hour) {
return hour == 12 || hour == 15 || hour == 17;
};
但是我遇到以下错误:
Uncaught TypeError: onHourShow.apply is not a function

我试图在Drupal堆栈交换中询问这个问题,但是被“搁置”,并告诉我这是一个编程问题,所以我在这里询问。
答案 0 :(得分:2)
jQuery UI Timepicker使用apply()
方法调用回调函数,例如'beforeShow','onSelect'等。 :
var beforeShow = $.timepicker._get(inst, 'beforeShow');
extendRemove(inst.settings, (beforeShow ? beforeShow.apply(input, [input, inst]) : {}));
因此,回调的类型必须是函数-而不是字符串。
问题在于模块 date_popup_timepicker 在初始化时间选择器之前未将字符串回调(从服务器传入)映射到实际的js函数回调,因此,一次 jquery.ui.timepicker。 js 代码运行会抛出一个Uncaught TypeError: <callback>.apply is not a function
。
在客户端,datePopup设置对象(来自Drupal.settings)可能包含字符串回调,因此,在调用timepicker()方法之前,必须将所有这些字符串转换为相应的函数 。到那里缺少什么:
var timepicker_callbacks = {
beforeShow: null,
onSelect: null,
onClose: null,
onHourShow: null,
onMinuteShow: null
};
function timepicker_callbacks_assign (settings) {
for (var setting in settings) {
if (setting in timepicker_callbacks && typeof settings[setting] === 'string') {
var namespace = window,
ns_callback = settings[setting].split('.'),
func = ns_callback.pop();
for (var i = 0; i < ns_callback.length; i++) {
namespace = namespace[ns_callback[i]];
}
settings[setting] = namespace[func];
}
}
}
timepicker()初始化发生在Drupal.behaviors.DatePopupTimepicker
中,我们只需要首先执行timepicker_callbacks_assign()
即可使timepicker获得正确的设置。
我创建了issue,并在drupal.org上提交了patch,它仍然是“ Needs Review”,因此请不要犹豫从那里申请并对其进行审查。
