如何從Angularjs中的對象數組中檢索數據？

Question

我打電話給rest服務，基於regInventoryId我想顯示與對象數組關聯的數據我能夠顯示一些對象，但有些我不能，從下面的代碼例如我無法在視圖中填充數據爲SubpartId。請讓我知道我在做什麼錯誤，歡迎任何暗示。

見代碼遠遠低於試過......

HTML

<div class="row"> 
     <div class="col-md-6"> 
      <h5> 
       <strong>Rule Id</strong> 
      </h5> 
      <div>{{lrrDetail.ruleIdentifier}}</div> 
     </div> 
     <div class="col-md-6"> 
      <h5> 
       <strong>SubpartID</strong> 
      </h5> 
      <div>{{lrrDetail.subPartId}}</div> 
     </div> 
    </div> 
    <hr class="modalHr"></hr> 
    <div class="row lrrDetailboxMrgn"> 
     <div class="col-md-6"> 
      <h5> 
       <strong>Rule Internal or Outsourced</strong> 
      </h5> 
      <div>Rule internal data</div> 
     </div> 
     <div class="col-md-6"> 
      <h5> 
       <strong>Subpart Internal or Outsourced</strong> 
      </h5> 
      <div>LRR Data one lorem ipsum</div> 
     </div> 
    </div> 

CTRL.JS

$scope.lrrDetailWinOptions = lrrSearchGridConfig.modalLrrConfig; 
    $scope.showDetail = function (id){ 
     $scope.selectedId = id; 
     lrrDetails.findlrrDetail(id.regInventoryId).then(function(response){ 
     $scope.lrrDetail = response.data; 
     $scope.$broadcast('openDetailWindow'); 
     }); 

    } 

FACTORY.JS

findlrrDetail: function(regInventoryId){ 
     return $http.get('/third-party-management/rest/lrr/' + regInventoryId); 
    }, 

};

Answer 1

首先，如果你做了很多這種類型的查找，然後過濾式操作的，你應該結帳Underscore.js。這是一個超級有用的圖書館。然後你可以使用它的_.findWhere()功能，像這樣（我打電話給你的json.js陣列json1爲清楚起見）：

$scope.lrrDetailWinOptions = lrrSearchGridConfig.modalLrrConfig; 
    $scope.showDetail = function (id){ 
    $scope.selectedId = id; 
     lrrDetails.findlrrDetail(id.regInventoryId).then(function(response){ 
     $scope.json2 = response.data; 
     $scope.lrrDetail = _.findWhere($scope.json1, {'regInventoryId':$scope.json2.id}); 
     $scope.$broadcast('openDetailWindow'); 
    }); 
} 

這將返回第一個匹配的json1陣列英寸現在，從json2數組中獲取正確值的語法可能會有所不同，但只需嘗試console.log(response.data)，直到找到要查找的值。例如，你可以嘗試像。 console.log(response.data[0].id);
