FullCalendar -引导模式"shown.bs.modal“有时不起作用

Question

在继续我以前的post，我有另一个问题。有时，在Select of Full Calendar中，当bootstrap modal打开jquery时，不会在模态中填充表单输入。

当在行中发生这种情况时，console.log($('#salas-date_begin').length);返回0。这种情况主要发生在Firefox中，当我的计算机同时处理多个数据时。

事件是：

select: function(start, end, jsEvent, view, resource) {
        $('#modal')
        .on('shown.bs.modal', function (e) {
           $('#salas-date_begin').val(moment(start).format('YYYY-MM-DD HH:mm'));
           $('#salas-date_end').val(moment(end).format('YYYY-MM-DD HH:mm'));
           console.log($('#salas-date_begin').length); //debug
        }).modal('show').find('#modalContent').load('http://url/create');
    },

所有代码：

<?php

use kartik\export\ExportMenu;
use yii\bootstrap\Modal;
use yii\helpers\Html;
use yii\grid\GridView;
use yii\helpers\Json;
use yii\web\View;
use yii\widgets\Pjax;
/* @var $this yii\web\View */
/* @var $searchModel common\models\SalasSearch */
/* @var $dataProvider yii\data\ActiveDataProvider */

$this->title = Yii::t('app', 'Salas');
$this->params['breadcrumbs'][] = $this->title;

$this->registerJsFile('https://fullcalendar.io/releases/fullcalendar/3.10.0/lib/moment.min.js', ['depends' => [\yii\web\JqueryAsset::className()]]);
$this->registerJsFile('https://fullcalendar.io/releases/fullcalendar/3.10.0/fullcalendar.min.js', ['depends' => [\yii\web\JqueryAsset::className()]]);
$this->registerJsFile('https://fullcalendar.io/releases/fullcalendar-scheduler/1.9.4/scheduler.min.js', ['depends' => [\yii\web\JqueryAsset::className()]]);

$script2 = <<< JS

$(document).ready(function() {
    $('#modal').on('hide.bs.modal', function (e) {
    console.log($(e.currentTarget).off('shown.bs.modal')); // or $(this)

    });
});
JS;
$this->registerJs($script2);

Modal::begin([
    'header' => '<b> NEW </b>',
    'id' => 'modal',
    'size' => 'modal-lg',
]);
echo "<div id='modalContent'></div>";
Modal::end();

?>

           console.log($('#salas-date_begin').length); //debug
        }).modal('show').find('#modalContent').load('http://url/create');
    },
    eventClick: function(event, jsEvent, view) {
        $('#modal')
        .modal('show').find('#modalContent').load('http://url/update?id=' + event.id);
    },
    schedulerLicenseKey: 'GPL-My-Project-Is-Open-Source',
    resourceLabelText: 'Rooms',
    events: events
});

JS;
$this->registerJs($script);

我想找到了解决办法。在触发shown.bs.modal时，可能有时表单还没有完全加载。

第一个加载msg (建议)的show modal，load form并等待它被加载，如果是加载的话，最后填写表单。

select: function(start, end, jsEvent, view, resource) {
        $('#modal').modal('show');
        $( "#modal #modalContent" ).load( "http://url/create", function( response, status, xhr ) {
            if(status === 'success') {
                $('#salas-date_begin').val(moment(start).format('YYYY-MM-DD HH:mm'));
                $('#salas-date_end').val(moment(end).format('YYYY-MM-DD HH:mm'));
            }
        });
  }
