</select>
这是从API获取时隙的代码：
<b>Select a timeslot: </b>
</br>Schedule is based on mentors availability & subject to approval.
<span id="spinner-mentor-checkDate"><small class="text-muted"><i class="fa fa-spinner fa-spin fa-lg fa-fw"></i> Checking...</small></span>
</div>
<div class="hidden">
<div class="col-xs-12 text-left clearfix">
<span id="box-BookSlotForm_date">
<?php echo $form->bsTextField($model, 'date'); ?>
</span>
<span id="box-BookSlotForm_time">
<?php echo $form->bsTextField($model, 'time'); ?>
</span>
<span class="input-group" style="max-width:8em;">
<span class="input-group-addon noborder">GMT</span>
<?php echo $form->bsTextField($model, 'timezone', array('readonly'=>'readonly')) ?>
</span>
</div>
</div>
<div class="full-width text-left margin-top-md">
<div id="box-nearbyDates"></div>
</div>
这是从API获取时隙的JavaScript：
// nearby
$('#box-nearbyDates').html('');
var programId = $('#BookSlotForm_programId').val();
var mentorId = $('#BookSlotForm_mentorId').val();
$.ajax({
async: false,
cache: true,
url: baseUrl+'/mentor/api/getAvailableTimeSlotsRecently',
data: { programId:programId, mentorId:mentorId},
}).done(function(json) {
if(json.status == 'success')
{
var htmlNearby = '';
timeSpan = 30*60*1000;
$.each(json.data.slots, function(index, timeslots) {
if(timeslots.length>0) htmlNearby += '<fieldset class="margin-bottom-lg"><legend class="nopadding nearby-date-font">'+moment(index).format('ddd, YYYY-MMM-DD')+'</legend>';
$.each(timeslots, function(indexTimeslot, timeslot){
var hour = timeslot.split(':')[0];
var min = timeslot.split(':')[1];
var newDate = new Date();
newDate.setHours(hour);
newDate.setMinutes(min);
var afterAddition = new Date(newDate.getTime() + $program->length*60000); //Adding 30 mins to the slot
var newHour = afterAddition.getHours() < 10 ? '0'+ afterAddition.getHours():afterAddition.getHours();
var newMin = afterAddition.getMinutes() < 10 ? '0'+ afterAddition.getMinutes(): afterAddition.getMinutes();
htmlNearby += '<a class="btn-timeslot-mentor btn-sm btn-white margin-sm btn-timeslotSuggestion timeslot-font" data-date="'+index+'" data-time="'+timeslot+'">'+timeslot + ' - ' + newHour + ':' + newMin + '</a>';
});
htmlNearby += '</fieldset>';
});
$('#box-nearbyDates').html(htmlNearby);
}
}).always(function(){
});
那么现在如何根据从下拉列表中选择的时区将时间从API更改为？
谢谢！
最佳答案
检查https://www.npmjs.com/package/ctoc_timezone
js可以处理div标签并将其转换为特定时区。阅读文档。
它接受的典型格式是-<div data-ctoc-timezone data-ctoc-time="Mar 01 2013 05:30:00 +5:30" data-ctoc-req-zone="" data-ctoc-req-format=""></div>
输出：Fri Mar 01 2013 05:30:00 GMT+0530 (India Standard Time)
您可以将“ data-ctoc-req-zone”设置为所需的区域，然后将时间转换为-<div data-ctoc-timezone data-ctoc-time="Mar 01 2013 05:30:00 +5:30" data-ctoc-req-zone="America/Lima" data-ctoc-req-format=""> </div>
输出：Thu Feb 28 2013 19:00:00
