我是新的角j。我试图调用工厂服务方法’getscoreData’从ng的变化，但不能够得到它完成。请帮忙。
<select ng-model="score" ng-change="getscoreData(score)" ng-options="c.name for c in scores"></select>
Angularjs代码：
var app = angular.module('audiapp',[]);
app.controller('audiLayoutCtrl',function ($scope,scoreDataService) {
scoreDataService.getscoreData($scope.score,function (data) {
$scope.scoreData = data;
});
});
app.factory('scoreDataService',function ($http) {
return {
getscoreData: function (score,callback) {
var params = {
questionCode: score.code
}
return $http({
url: 'Home/GetAvgData',method: 'GET',params: params
}).success(callback);
}
};
});
您的代码至少有两个问题：
> ng-change =“getscoreData(score)
Angular没有看到getscoreData方法引用定义的服务
> getscoreData：function(score，callback)
我们不需要使用回调，因为GET返回promise。然后改用。
这里是一个工作示例(我使用随机地址仅用于模拟)：
HTML
<select ng-model="score" ng-change="getscoreData(score)" ng-options="score as score.name for score in scores"></select> <pre>{{scoreData|json}}</pre>
JS
var fessmodule = angular.module('myModule',['ngResource']);
fessmodule.controller('fessCntrl',function($scope,scoreDataService) {
$scope.scores = [{
name: 'Bukit Batok Street 1',URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore,SG,Singapore,153 Bukit Batok Street 1&sensor=true'
},{
name: 'London 8',London 8&sensor=true'
}];
$scope.getscoreData = function(score) {
scoreDataService.getscoreData(score).then(function(result) {
$scope.scoreData = result;
},function(result) {
alert("Error: No data returned");
});
};
});
fessmodule.$inject = ['$scope','scoreDataService'];
fessmodule.factory('scoreDataService',['$http','$q',function($http) {
var factory = {
getscoreData: function(score) {
console.log(score);
var data = $http({
method: 'GET',url: score.URL
});
return data;
}
}
return factory;
}]);
