我正在尝试向Angular Bootstrap Typeahead传递一个承诺,但我总是遇到以下错误: TypeError:无法读取未定义的属性“length”

厂:

    angular.module('app').factory('geoCoding', ['$http', 'geoUtils', function ($http, geoUtils) {

  var request= function(location){
    return $http.get('http://open.mapquestapi.com/geocoding/v1/address',{params:{location:location}});
  };

  var ret = {};

  ret.locate = function (location) {
    return request(location).then(function (data) {
      if (data  && data.data && data.data.results && data.data.results[0]) {
        var locations = [];
        data.data.results[0].locations.forEach(function (location) {
          locations.push({name: geoUtils.location2String(location), location: location});
        });
        return locations;
      }
    });
  };
  return ret;
}]);

控制器:

$scope.getLocations = function(){
    console.log('scope',$scope.inputLocation);
    return geoCoding.locate($scope.inputLocation);
  }

模板:

        <input type="text" class="form-control oo-focus" placeholder="Search" typeahead="location as location.name for location in getLocations()" typeahead-wait-ms="500" ng-model="inputLocation" />

使用旧版Angular Bootstrap-UI 0.5.0一切正常。问题出在Bootstrap-UI 0.6.0(bootstrap3_bis2)上。 https://github.com/angular-ui/bootstrap/tree/bootstrap3_bis2

如果您正在使用AngularJS 1.2.0-rc.2,则承诺存在问题(更改了承诺自我引用的公开 - 或者像这样的想法:))。我无法告诉你为什么,但你可以在这里找到更多信息:

Typehead broken when using promises in Angularjs 1.2.0rc2

对我来说,wirking解决方案是设置promise。$$ v变量。所以在你的例子中,代码应该是:

$scope.getLocations = function(){
   console.log('scope',$scope.inputLocation);
   var promise = geoCoding.locate($scope.inputLocation);
   promise.$$v = promise;
   return promise;
}

我同意作者(wilsonjackson),这很hacky!无论如何希望它会帮助你。
