Question

我有一个fullcalendar，外部元素被拖到它上面。我对jquery比较新。我不知道如何将被拖动对象的ID转换为“垃圾桶”图标。我只是想将日历中的项目拖到图像上，当我放开鼠标时，项目就会被移除。

这是我的代码.....

完成教程，如何将“移至垃圾箱”功能添加到fullcalendar

enter image description here

HERE IS DEMO

如果您不想使用droppable：

来自fullcalendar.css的

删除此行

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

在fullcalenar.js中找到（行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]();
        }
    }
}

并改为：

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]();
            }
        }
    }
}

在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");
        }
    }
},

在fullcalendar中设置选项dragRevertDuration：0，

在fullcalendar声明中添加加载回调函数以附加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>');

    }
},

垃圾css：

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;
}

如果加载回调不起作用，请在jquery文档就绪函数的末尾添加垃圾。

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

垃圾桶图标：

Answer 2

首先，您需要从css中删除溢出语句：

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

然后您可以使用eventDragStop

Answer 3

这是我希望它有所帮助的东西。我不知道你是否使用php / mysql，但如果你不只是删除了ajax调用并保留了成功函数中的内容。

        $('#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 4

我告诉我们drop：function（event，ui）ui :: ui保存一个空对象。在2.1版之前，jQuery UI对象。 :)然后工作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;

}

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);
                }

        }
    }

从fullcalendar中删除元素（通过拖动到垃圾桶）
