我正在尝试使用 Angular 指令实现拖放日历。日历使用 ui-calendar ( https://github.com/angular-ui/ui-calendar )，这是 Arshaw FullCalendar 的完整 AngularJS 指令。
将元素拖放到日历上由 angular-dragdrop ( https://github.com/codef0rmer/angular-dragdrop ) 提供支持。
这是my try在文件夹 demo/ui-calendar/demo 中，但是当我将元素放到日历上时，不会触发任何事件...
html 很简单，如下所示:
<html lang="en" ng-app="calendarDemoApp" id="top" class="ng-scope">
<head>
<style type="text/css">@charset "UTF-8";[ng\:cloak],[ng-cloak],[data-ng-cloak],[x-ng-cloak],.ng-cloak,.x-ng-cloak,.ng-hide{display:none !important;}ng\:form{display:block;}.ng-animate-block-transitions{transition:0s all!important;-webkit-transition:0s all!important;}</style>

最佳答案
没有使用 angular-dragdrop，但文档说配置对象应该包含一个 onDrop 属性。尝试更换 jqyoui-droppable="{multiple:true}"与 jqyoui-droppable="{multiple:true, onDrop: 'drop'}" . angular-dragdrop 似乎期待 onDrop是一个字符串，在作用域上有一个函数的名字。
