Remove Elements from fullcalendar (by dragging to trash can)

Question

I have a fullcalendar with external elements being dragged onto it. I\'m relatively new to jquery. I don\'t know quite how to get the ID of the object being dragged to a \

Answer 1

first of all you're gonna need to remove overflow statement from css:

 .fc-view
 {
   /* prevents dragging outside of widget */
   width: 100%;
   overflow: hidden;
 }

then you can use eventDragStop

Answer 2

i tell us drop: function(event, ui) ui :: ui holds an empty object. Before version 2.1, the jQuery UI object. :) and work then jsEvent :) sn :

eventDragStop: function(event, jsEvent, ui, view) {

       if (isElemOverDiv(jsEvent, $('div#external-events'))) {

           console.log(isElemOverDiv(jsEvent, $('div#external-events')));
           $('.calendario').fullCalendar('removeEvents', event.id);
       }
   }

  var isElemOverDiv = function(draggedItem, dropArea) {
  var p = dropArea;
  var position = p.position();
  console.log("EL DROP AREA left: " + position.left + ", top: " + position.top);
  console.log('draggedItem.pageY ', draggedItem.clientX, draggedItem.pageY);
  if (draggedItem.clientX >= position.left && draggedItem.pageY >= position.top) {
      return true;
  }
  return false;

}

Complete tutorial, how to add "move to trash" function to fullcalendar

HERE IS DEMO

if you do not want to use droppable:

from fullcalendar.css delete this lines

.fc-view
 {
   /* prevents dragging outside of widget */
   width: 100%;
   overflow: hidden;
 }

find in fullcalenar.js (line cca 6086)

function eachEventElement(event, exceptElement, funcName) {
    var elements = eventElementsByID[event._id],
        i, len = elements.length;
    for (i=0; i<len; i++) {
        if (!exceptElement || elements[i][0] != exceptElement[0]) {
            elements[i][funcName]();
        }
    }
}

and change to:

function eachEventElement(event, exceptElement, funcName) {
    var elements = eventElementsByID[event._id],
        i;
    if (elements != null) {
        var len = elements.length;
        for (i = 0; i < len; i++) {
            if (!exceptElement || elements[i][0] != exceptElement[0]) {
                elements[i][funcName]();
            }
        }
    }
}

in js:

//actually cursor position
var currentMousePos = {
    x: -1,
    y: -1
};

//set actually cursor pos
jQuery(document).ready(function () {

    jQuery(document).on("mousemove", function (event) {
        currentMousePos.x = event.pageX;
        currentMousePos.y = event.pageY;
    });

});

//check if cursor is in trash 
    function isElemOverDiv() {
        var trashEl = jQuery('#calendarTrash');

        var ofs = trashEl.offset();

        var x1 = ofs.left;
        var x2 = ofs.left + trashEl.outerWidth(true);
        var y1 = ofs.top;
        var y2 = ofs.top + trashEl.outerHeight(true);

        if (currentMousePos.x >= x1 && currentMousePos.x <= x2 &&
            currentMousePos.y >= y1 && currentMousePos.y <= y2) {
            return true;
        }
        return false;
    }

//fullcalendar mouseover callback

        eventMouseover: function (event, jsEvent) {
            $(this).mousemove(function (e) {
                var trashEl = jQuery('#calendarTrash');
                if (isElemOverDiv()) {
                    if (!trashEl.hasClass("to-trash")) {
                        trashEl.addClass("to-trash");
                    }
                } else {
                    if (trashEl.hasClass("to-trash")) {
                        trashEl.removeClass("to-trash");
                    }

                }
            });
        },

//fullcalendar eventdragstop callback
eventDragStop: function (event, jsEvent, ui, view) {
    if (isElemOverDiv()) {

        jQuery('#fr-calendar').fullCalendar('removeEvents', event.id);

        var trashEl = jQuery('#calendarTrash');
        if (trashEl.hasClass("to-trash")) {
            trashEl.removeClass("to-trash");
        }
    }
},

in fullcalendar set option dragRevertDuration: 0,

in fullcalendar declaration add loading callback function for append a trashcalendar:

loading: function (bool) {
    if (!bool) {
        jQuery('.fc-header-left').append('<div id="calendarTrash" class="calendar-trash"><img src="' + imagePath + '/cal-trash.png"></img></div>');

    }
},

css for trash:

div.calendar-trash{
float: left;
padding-right: 8px;
margin-right:5px;
padding-left:8px;
padding-top: 3px;
cursor: pointer;
}

.to-trash{
  background-color:#EAEAEA;
    -webkit-border-radius: 5em;
    border-radius: 5em;
}

If loading callback not working, add trash on end of jquery document ready function.

foo.JFS('.fc-header-left').append('<div id="calendarTrash" class="calendar-trash"><img src="/images/cal-trash.png"></img></div>');

trash icon:

Answer 4

here is something I just did hope it helps. I dont know if you are using php/mysql but if your not just remove the ajax call and keep what is in the success function.

        $('#calendar').children('.fc-content').children().append('<div id="calendarTrash" style="float: right; padding-top: 5px; padding-right: 5px; padding-left: 5px;"><span class="ui-icon ui-icon-trash"></span></div>');

    //listens for drop event
    $("#calendarTrash").droppable({
        tolerance: 'pointer',
        drop: function(event, ui) { 
            if ( dragged && ui.helper && ui.helper[0] === dragged[0] ) {
                var event = dragged[1];
                var answer = confirm("Delete Event?")
                if (answer)
                {
                    $.ajax({
                        url:'/employees/removeevent?id='+event.id,
                        dataType: 'json',
                        async: false,
                        error: function(xhr, ajaxOptions, thrownError)
                        {
                            //console.log(xhr.status);
                            //console.log(thrownError);
                        },
                        success: function()
                        {
                            calendar.fullCalendar( 'removeEvents' , event.id  );
                        }
                    });
                }
            }
        }
    });

        eventDragStart: function( event, jsEvent, ui, view ) { 
            dragged = [ ui.helper[0], event ];
        },

Answer 5

 <div id="calendarTrash" class="calendar-trash"><img src="images\trash.png"  alt="image"/></div>


 ` eventDragStop: function(event,jsEvent) {

        var trashEl = jQuery('#calendarTrash');
        var ofs = trashEl.offset();

        var x1 = ofs.left;
        var x2 = ofs.left + trashEl.outerWidth(true);
        var y1 = ofs.top;
        var y2 = ofs.top + trashEl.outerHeight(true);

        if (jsEvent.pageX >= x1 && jsEvent.pageX<= x2 &&
            jsEvent.pageY >= y1 && jsEvent.pageY <= y2) {
                if (confirm("Are you sure to  detete " + event.title +" ?")) {
                    //pour annuker les informations
                    $('#external-calendar').fullCalendar('removeEvents', event._id);
                }

        }
    }
