我目前正在 youtube 上浏览 angularjs 1 服务教程，但我陷入了以下困境。
我正在尝试让selectedElement显示在我的index.html文件中
使用以下代码时显示该值:
{{ sensormeasurements[0].sensorMeasurementID }}
但是以下任何组合都不会。
{{ selectedElement.sensorMeasurementID }}
{{ sensormeasurements.selectedElement.sensorMeasurementID }}
{{ fishHouseMonitorController.selectedElement.sensorMeasurementID }}
{{ $scope.selectedElement.sensorMeasurementID }}
关于使 selectedElement.sensorMeasurementID 显示在我的 HTML 页面上的正确语法有什么想法吗？
感谢您对此的帮助。 史蒂夫
我的 app3.js 文件中有以下代码
var app = angular.module('fishHouseMonitorApp', []);
app.controller('fishHouseMonitorController', function($scope, $http) {
$http.get("http://www.eastcentralmdaa.org/fishhousemonitor/api/v1/sensormeasurements")
.then(function(response) {
$scope.sensormeasurements = response.data; });
// do some error checking to ensure there is an element 0?
$scope.selectedElement = $scope.sensormeasurements[0];
}
);
我的 index.html 文件中有以下代码

最佳答案
我发现了我的错误。
<script src="app2.js">app3.js</script>
我修改了错误的文件...
