这是我在 angular.js 中使用服务的代码。如果我运行此代码 我收到此错误未捕获错误:[ng:areq]。

<div ng-controller="testAppController">
Search: <input ng-model="query" type="text" class="text-input" id="my-input"/>
<table>
<tr>
<th>Country</th>
<th>Population</th>
</tr>
<tr ng-repeat="country in countries | filter:query">
<td>{{country.name}}</td>
<td>{{country.population}}</td>
</tr>
</table>
</div>
<div ng-include='"partials/footer.html"'></div>
</ons-page>
演示.js
angular.module('testsapp',[])
.service('helloworldservice',function($http){
this.getDatafunction = function(){
$http.get('json/countries.json')
.success(function(data) {
alert("sucesss");
})
.error(function(data) {
alert("wrong");
});
}
})
.controller('testAppController',['helloworldservice',function($scope,helloworldservice){
helloworldservice.getDatafunction();
}]);
最佳答案
这里
.controller('testAppController',['helloworldservice',function($scope,helloworldservice)
您需要更改为
.controller('testAppController',['$scope','helloworldservice',function($scope,helloworldservice)

$http.get('json/countries.json').
success(function(data) {
alert("sucesss");
}).
error(function(data) {
