我的仪表板在下面

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

function dashboard(common) {
    var getLogFn = common.logger.getLogFn;
    var log = getLogFn(controllerId);

    var vm = this;
    vm.news = {
        title: 'Hot Towel Angular',
        description: 'Hot Towel Angular is a SPA template for Angular developers.'
    };
    vm.messageCount = 0;
    vm.people = [];
    vm.title = 'Dashboard';

    //Call Active Init
    activate();

    function activate() {
        var promises = [getMessageCount(), getPeople()];
        common.activateController(promises, controllerId)
            .then(function () { log('Activated Dashboard View'); });
    }

    function getMessageCount() {
        return datacontext.getMessageCount().then(function (data) {
            return vm.messageCount = data;
        });

    }

    function getPeople() {
        return datacontext.getPeople().then(function (data) {
            return vm.people = data;
        });

    }
}

})()；

为什么数据文本没有定义？

Answer 1

您没有在dashboard定义中加载它。

在这里，您定义了一个控制器，并注入了两个依赖项，common和datacontext，这很好：

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

但是在这里，您将dashboard函数(控制器定义中的最后一个参数)定义为只有一个参数：

function dashboard(common)

....so，您正在注入的datacontext实际上被忽略了。您应该将dashboard定义更改为：

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