javascript – 从fullcalendar中删除元素(通过拖动到垃圾桶)

我有一个fullcalendar,外部元素被拖到它上面.我比较新的 jquery.我不知道如何获取被拖动到“垃圾桶”图标的对象的ID.我只想将项目从日历中拖出到图像中,当我放开鼠标时,该项目被删除.

这是我的代码…..

解决方法

完整的教程,如何添加“移至垃圾桶”功能到fullcalendar

HERE IS DEMO

如果不想使用droppable：

从fullcalendar.css删除这行

.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]();
        }
    }
}

并更改为：

function eachEventElement(event,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设置选项dragRevertDuration：0,

在fullcalendar声明中添加加载回调函数附加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>');
 
    }
},

垃圾的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文档就绪功能的末尾添加垃圾桶.

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