我正在尝试使用angularjs读取并加载此json响应，并尝试将数据加载到hansontable中。
正如您在控制台中看到的，日志结果显示为OK，但不在外部。你能说出发生了什么吗？因为它正在读取响应但未按预期设置范围变量。
result1：{＆＃34; $$ state＆＃34;：{＆＃34; status＆＃34;：0}}
result2：undefined
这是一个非常简单的阅读和显示信息。所有脚本都在CoffeeScript中。 还在服务器端使用ngHandsonTable和rails。

Angularjs代码：

app.factory "Ano_escolar", ["$resource", ($resource) ->

JSON.stringify(result))

app.controller("GradesCtrl", GradesCtrl)
这是我得到的控制台日志：

我尝试修复使用此代码
$scope.searchGrades = -> Notas.get({ano_escolar: $scope.ano_escolar, materia: $scope.materia, semestre: $scope.semestre, curso: $scope.curso, seccion:$scope.seccion, tanda: $scope.tanda}).$promise.then( (result) ->
$scope.resultData = result.aaData
console.log('resultData: ' + JSON.stringify(result)))
但是现在它工作并且当结果不为空时设置$ scope.resultData。
