问题
I am using JQuery Full Calendar along with Spring MVC.
Hello, I have made a demo like that.
Target: I need when the user clicks on an event s/he already inserted,a dialog box appears and gives him/her the capability to either remove that event or cancel.
Issue: Now whenever the user clicks on any day, a dialog appears to allow the user to enter title for that event then user clicks "Ok" to save that event.
Freemarker: Freemarker:
<script type="text/javascript">
var resourceVacation;
function censor(censor) {
return (function() {
var i = 0;
return function(key, value) {
if (i !== 0 && typeof(censor) === 'object' && typeof(value) == 'object' && censor == value)
return '[Circular]';
++i; // so we know we aren't using the original object anymore
return value;
}
})(censor);
}
function doAjax() {
$.each(resourceVacation, function(index) {
var tmpDate = resourceVacation[index].start;
tmpDate.setHours(tmpDate.getHours() - tmpDate.getTimezoneOffset() / 60);
resourceVacation[index].start=tmpDate;
});
// var arrays = [
// {"id":111,"title":"event1","start":"2012-04-15T22:00:00.000Z","url":"http://yahoo.com/"}

function(start, end, allDay) {

if (title) {
start.setHours(start.getHours() - start.getTimezoneOffset() / 60);
// var dat=$.fullCalendar.formatDate( start, "yyyy/MM/dd")
var newVacation= {id:133,title:'title',start:start,url: 'title'};
resourceVacation.push(newVacation);
calendar.fullCalendar('renderEvent',
{
title: title,
start: start,
end: end,
allDay: allDay
},
true // make the event "stick"
);
}
calendar.fullCalendar('unselect');
},
eventClick: function(calEvent, jsEvent, view) {
alert('Event: ' + calEvent.title);
alert('start: ' + calEvent.start);
}
editable: true,
events:data
});
resourceVacation = data;
});
});
</script>
Controller:
@RequestMapping(value = "/vacation/loadResourceVacation", method = RequestMethod.GET)
public
@ResponseBody
String loadResourceVacation(HttpServletResponse response) throws Exception {
//Here I build my vacationFormBean
List<VacationFormBean> vacationFormBeanList= buildVacationFormBean();
// Convert to JSON string.
String json = new Gson().toJson(vacationFormBeanList);
// Write JSON string.
response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
return json;
}
@RequestMapping(value = "/vacation/saveResourceVacation", method = RequestMethod.POST)
public
@ResponseBody
void saveResourceVacation(@RequestBody String jsonString, Principal principal) throws Exception {
List<String> resourceVacations = extractVacationDatesFromJsonObject(jsonString);
}
VacationFormBean:
public class VacationFormBean {
int id; // (With Setter & Getter)
String title; // (With Setter & Getter)
String start; // (With Setter & Getter)
String url; // (With Setter & Getter)
}
I need something like that :
======================UPDATE=========================
I have add the click event as a result of domi27 recomendation. Kindly review the freemarker updates. I have added a java script method that uses :http://arshaw.com/fullcalendar/docs/event_data/removeEvents/
The new JS method :
$('#calendar').fullCalendar('removeEvents', 1);
This method works perfectly with the events that was initially loaded from the controller. However,whenever I try to use the same method to remove the new events I have just added,Nothing happens. When I fire the "select event" for the new event I created ,I get for its id"undefined".
As I've mentiond on my freemarker,that are the lines I use to build the new event object that I aappend to the list.
var newVacation = {id:'133',title:'title',start:start,url: 'title'};
resourceVacation.push(newVacation);
When I debug my script,I observe a difference among the objects loaded from the controller and the new object I created when the user adds a new event.
Here is the old object I got from the controller when I initiated the calendar:
Here is the new Object I got after I insert the new event:

You may implement it like this :
- Fetch click on an event
- Display information about (how to) delete this event
- Call an ajax request to process deletion of event in backend
- Delete event from calendar frontend
1) First is described here : http://arshaw.com/fullcalendar/docs/mouse/eventClick/
2) Quite simpliest JS: confirm("Really want to delete this event ?")
3) Call a delete action via jQuery likely as you do to save a reservation
4) Remove this event via fullcalendars "removeEvents" method : http://arshaw.com/fullcalendar/docs/event_data/removeEvents/
Here's a short and very basic example :
eventClick: function(calEvent, jsEvent, view) {
/**
* calEvent is the event object, so you can access it's properties
*/
if(confirm("Really delete event " + calEvent.title + " ?")) {
// delete event in backend
jQuery.post(
"/vacation/deleteEvent"
, { "id": calEvent.id }
);
// delete in frontend
calendar.fullCalendar('removeEvents', calEvent.id);
}
}
回答2:
I have make it work by the following approach: whenever the user fires whether the "select" or "click" event over the full calendar, I go to and search by the date the user selected and remove it from the my JS array. I use :$('#calendar').fullCalendar('removeEvents', id) to remove it from the full calendar event.
