Laravel-弃用警告:提供的值不是可识别的RFC2822或ISO格式

Question

我正在使用Laravel-5.8和jQuery fullcalendar用于Leavel应用程序：

控制器

public function index()
{
try {  
$userCompany    = Auth::user()->company_id;
$userID         = Auth::user()->id;
$userEmployee = Auth::user()->employee_id;
$leaverequests = HrLeaveRequest::where('employee_id', $userEmployee)->where('company_id', $userCompany)->whereYear('created_at', date('Y'))->get();
return view('service.leave_requests.index')->with('leaverequests', $leaverequests);
} catch (Exception $exception) {
Session::flash('error', 'Action failed! Please try again');
return back();
}           
}

index刀片

<div class="card-body p-0"> 
<div id='calendar'></div>
</div>
@section('javascript')
<script src="{{ asset('theme/adminlte3/plugins/jquery/jquery.min.js') }}"></script>
<script src="{{ asset('theme/adminlte3/plugins/moment/moment.min.js') }}"></script>
<script src="{{ asset('theme/adminlte3/plugins/jquery-fullcalendar/fullcalendar.min.js') }}"></script>
<script src="{{ asset('theme/adminlte3/plugins/jquery-ui/jquery-ui.min.js') }}"></script>
<script>
$(document).ready(function () {
// page is now ready, initialize the calendar...
$('#calendar').fullCalendar({
// put your options and callbacks here
header: {
left: 'prev,next,today',
center: 'title',
right: 'month,basicWeek,basicDay'
},
events : [
@foreach($leaverequests as $leaverequest)
{
title : '{{ $leaverequest->leavetype->leave_type_name }}',
fullname : '{{ $leaverequest->employee->first_name . ' ' . $leaverequest->employee->last_name }}',
start : '{{ CarbonCarbon::parse($leaverequest->commencement_date)->format('d-m-Y') ?? '' }}',
end: '{{ CarbonCarbon::parse($leaverequest->resumption_date)->format('d-m-Y') ?? '' }}',
url : '{{ route('service.leave_requests.edit', $leaverequest->id) }}'
},
@endforeach
] 
})
});
</script>
@stop

当我呈现页面时，我得到了这个错误：

moment.min.js:1 Deprecation warning: value provided is not in a recognized RFC2822 or ISO format. moment construction falls back to js Date(), which is not reliable across all browsers and versions. Non RFC2822/ISO date formats are discouraged and will be removed in an upcoming major release. Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info.

当我删除此代码时：

start : '{{ CarbonCarbon::parse($leaverequest->commencement_date)->format('d-m-Y') ?? '' }}',
end: '{{ CarbonCarbon::parse($leaverequest->resumption_date)->format('d-m-Y') ?? '' }}',

从#calendar脚本中，错误消失了，但日历上没有显示任何内容。

我如何让日历工作仍然放这个代码？

start : '{{ CarbonCarbon::parse($leaverequest->commencement_date)->format('d-m-Y') ?? '' }}',
end: '{{ CarbonCarbon::parse($leaverequest->resumption_date)->format('d-m-Y') ?? '' }}',

谢谢

Answer 1

这不是一个错误，它只是一个警告，它告诉您在下一次momentjs更新中不再支持什么。

您可以通过执行警告中所说的操作来轻松解决此问题：提供RFC2822或ISO日期。

CarbonCarbon::parse($leaverequest->commencement_date)->toRfc2822String()

或

CarbonCarbon::parse($leaverequest->commencement_date)->toISOString()
