我有一个在webpack js中呈现的日历模块- app/javascript/packs/application.js
document.addEventListener('DOMContentLoaded', function() {
var calendarEl = document.getElementById('calendar');
var calendar = new Calendar(calendarEl, {
plugins: [ interactionPlugin, dayGridPlugin, timeGridPlugin, listPlugin, momentPlugin ],
header: {
left: 'prev,next today',
center: 'title',
right: 'dayGridMonth,timeGridWeek,timeGridDay,listWeek'
},
defaultDate: '2018-01-12',
navLinks: true, // can click day/week names to navigate views
editable: true,
eventLimit: true, // allow "more" link when too many events
selectable: true,
events: '/events.json',
select: function(info) {
$.getScript('/events/new', function(){
$('#event_date_range').val(moment(info.start).format('YYYY-MM-DD HH:mm') + ' - ' + moment(info.end).format('YYYY-MM-DD HH:mm'));
$('#start_date').val(moment(info.start).format('YYYY-MM-DD HH:mm'));
$('#end_date').val(moment(info.end).format('YYYY-MM-DD HH:mm'));
});
}
});
calendar.render();
});

我有一个create动作,想在成功的回调-上重新呈现日历create.js.erb。我怎样才能做到这一点?
注意:我假设您使用的是 Rails 6。我还假设您添加format.js到了创建操作中。
忘记吧create.js.erb,你在这里不需要它。
另外,您不应该将代码放入app/javascript/packs/application.js.
该文件中的评论如下:
该文件与该目录中存在的任何其他文件一起由 Webpack 自动编译。我们鼓励您将实际的应用程序逻辑放置在app/javascript 中的相关结构中,并且仅使用这些包文件来引用该代码,以便对其进行编译。
这就是你构建它的方式:
app/javascript/calendar文件:index.js
// import your calendar object (put it in a file calendar.js in the same folder)
import Calendar from './calendar';
document.addEventListener('DOMContentLoaded', function() {
var calendarEl = document.getElementById('calendar');
var calendar = new Calendar(calendarEl, {
plugins: [ interactionPlugin, dayGridPlugin, timeGridPlugin, listPlugin, momentPlugin ],
header: {
left: 'prev,next today',
center: 'title',
right: 'dayGridMonth,timeGridWeek,timeGridDay,listWeek'
},
defaultDate: '2018-01-12',
navLinks: true, // can click day/week names to navigate views
editable: true,
eventLimit: true, // allow "more" link when too many events
selectable: true,
events: '/events.json',
select: function(info) {
$.getScript('/events/new', function(){
$('#event_date_range').val(moment(info.start).format('YYYY-MM-DD HH:mm') + ' - ' + moment(info.end).format('YYYY-MM-DD HH:mm'));
$('#start_date').val(moment(info.start).format('YYYY-MM-DD HH:mm'));
$('#end_date').val(moment(info.end).format('YYYY-MM-DD HH:mm'));
});
}
});
// actually, you want to put that addEventListener on your form
// more on 'ajax:success': https://guides.rubyonrails.org/working_with_javascript_in_rails.html#rails-ujs-event-handlers
document.body.addEventListener('ajax:success', function(event) {
var detail = event.detail;
var data = detail[0], status = detail[1], xhr = detail[2];
if (status === 'OK') { // upon success
// do something
// re-render the calendar
calendar.render();
}
})
calendar.render();
});

请注意我添加的部分:
// actually, you want to put that addEventListener on your form
// more on 'ajax:success': https://guides.rubyonrails.org/working_with_javascript_in_rails.html#rails-ujs-event-handlers
document.body.addEventListener('ajax:success', function(event) {
var detail = event.detail;
var data = detail[0], status = detail[1], xhr = detail[2];
if (status === 'OK') { // upon success
// do something
// re-render the calendar
calendar.render();
}
})

接下来,您创建包文件app/javascript/packs/calendar.js,并在其中引用您的模块,如下所示:
// importing calendar module
import '../calendar';

现在 Webpack 将自动编译您的文件。
剩下的就是使用javascript_pack_tag添加脚本标签的帮助器,该脚本标签引用由 webpack 编译的命名包文件:<%= javascript_pack_tag 'calendar' %>。将其添加到视图文件的底部(例如index.html.erb)。
希望这可以帮助。
