为什么未定义datacontext？

Answer 1

您没有在dashboard定义中加载它

在这里，您要定义一个控制器，并注入两个依赖项，即common和datacontext ，这很好：

angular.module('app').controller(controllerId, ['common', 'datacontext', dashboard]);

但是在这里，您正在定义dashboard功能（控制器定义中的最后一个参数），使其仅具有一个参数：

function dashboard(common)

....从而实际上忽略了您正在注入的数据datacontext 。 您应该将dashboard定义更改为：

function dashboard(common, datacontext) {
   ...
}
