找到 dispatch: function (e) { e = b.event.fix(e); var n, r, i, s, o, u = [], a = d.call(arguments), f = (b._data(this, "events") || {})[e.type] || [], l = b.event.special[e.type] || {}; a[] = e, e.delegateTarget = this; ) return; u = b.; while ((s…

在Event Handler中,有一种特殊的Event Handler,称之为Synchronizer或者Denormalizer,其作用就是为了同步“Query Database”.Query Database是为查询提供数据源的存储机制,用户在UI上看到的查询数据均来源于此数据库.因此,CQRS不仅分离了用户操作,而且分离了数据源,这样做的一个最大的优点就是,设计人员可以根据UI的需求来配置和优化Query Database,例如,可以将Query Database设计为一张数据表对应一个U…

一直以来对于Event Handler的感觉就是:添加.编辑和删除动作之前和动作之后,我们在SharePoint系统中可以做的一些事情 不过在最近处理的一个问题中,发现它在触发时机上出了一点问题   问题现象 在对调查列表(Survey List)添加事件的时候,明明绑定的列表编号是102 <Receivers "> 但是在自定义(Custom List)列表进行操作的时候,也会触发调查列表定义的事件动作,导致抛出一系列的异常L   处理办法 在函数的入口参数中进行判断,如下 if…

Event Handler支持在某个事件触发的时候定义好处理该事件的逻辑,比如错误事件触发是该怎么处理.它跟Control Flow界面相似,就好像执行了另外一个包一样.Event Handler不仅支持包内的task对象,还支持对Event Hanlder事件中的task. Event Handler可以触发组件级别或者包级别的事件,包括 FireBreakpointHit:这个一般应该用在调试时:FireError:错误发生时,这个也应该是最被常用到的:FireInformation:信息级…
