Question

我知道这个回调函数有问题。但我不确定解决这个问题的最佳方法是什么。

我有一个资源：

.factory("AutoCompleteResource", function ($http) {
    return {
        getAutoComplete: function (searchTerm) {
            $http.get('/cdeCompletion/' + searchTerm, {}).then(function (response) {
                response.data;
            });
        }
    }
})

这是控制器：

 $scope.getAutoComplete = function (searchTerm) {
    AutoCompleteResource.getAutoComplete(searchTerm);
}

这是html视图：

<input name="searchTerms" id="searchTerms" type="text" class="form-control" ng-model="ftsearch"
                       ng-maxlength="500" placeholder="Search Common Data Elements"
                       typeahead-wait-ms="500" typeahead-min-length="3"
                       typeahead="searchQuery for searchQuery in getAutoComplete($viewValue) | filter:$viewValue | limitTo:8"
                       typeahead-focus-first="false" typeahead-on-select="gotoSearch()">

此处修复错误的最佳方法是什么？谢谢！

您需要将承诺退还给预先承诺，因为它可以处理承诺并自动解决数据，即

.factory("AutoCompleteResource", function ($http) {
    return {
        getAutoComplete: function (searchTerm) {
          //Return here
           return $http.get('/cdeCompletion/' + searchTerm, {}).then(function (response) {
                return response.data; //return here
            });
        }
    }
});

和

$scope.getAutoComplete = function (searchTerm) {
    //Return here
    return AutoCompleteResource.getAutoComplete(searchTerm);
}
