javascript - 在 CRM 2011 Javascript 中获取架构名称

Question

如何在 CRM 2011 Javascript 的记录中获取特定字段的架构名称...？

Answer 1

字段的名称应与“id”属性相同。

如果您碰巧正在处理某个字段的事件，则始终可以在定义函数时传递执行上下文，然后在事件代码中使用：

executionContext.getEventSource().getName();

如果您需要基于字段 id/name（小写）的模式名称（混合大小写），您可以使用类似这样的内容（基于http://crmxpg.nl/wp/2010/10/19/how-to-通过javascript查询元数据服务）

function GetSchemaName() {

    alert(gGetAttributeList(Xrm.Page.data.entity.getEntityName(), "thefieldname"));

}
