我想在選擇值的基礎上顯示隱藏表單字段。例如我的表單有5個文本字段和1個選擇選項字段在這些字段中,4個字段取決於選擇值。如果我選擇布料,那麼布料類型和布料價值仍然存在,其他類型和價值隱藏。但是當我選擇包類型和其他值仍然隱藏。我正在嘗試一些條件和ng-class="{'hideCheck': isHideCheck}"模型,但它的行爲異常。AngularJs:根據選擇值顯示隱藏字段

var app = angular.module('mainApp', []); 
 

 
\t app.controller('appCont', function($scope) { 
 
\t 
 
\t \t \t $scope.ProductTypeChnaged = function() { 
 
      $scope.ProductStatus = $scope.ProductValue; 
 
\t \t \t 
 
\t \t \t if ($scope.AccountStatus == 'checking') { 
 
\t \t \t \t \t $scope.isHideCheck = !$scope.isHideCheck; 
 
\t \t \t \t } else if ($scope.AccountStatus == 'saving'){ 
 
\t \t \t \t \t $scope.isHideSave = !$scope.isHideSave; 
 
\t \t \t \t \t } 
 
     }; 
 
\t 
 
\t });
.hideCheck{display:none} 
 
.hideSave{display:none}

使用納克隱藏來隱藏元件。 ng-class用於改變css。

我改變了你的代碼,當選項checking被選中時,它會隱藏元素valus and type,只是你的一個例子,不實現你的羽毛。你想閱讀https://docs.angularjs.org/api/ng/directive/ngHide。順便說一句,ng-repeat是一個很好的方法來做表事物。

var app = angular.module('mainApp', []); 
 

 
\t app.controller('appCont', function($scope) { 
 
\t 
 
\t \t \t $scope.ProductTypeChnaged = function() { 
 
      $scope.ProductStatus = $scope.ProductValue; 
 
\t \t \t 
 
\t \t \t if ($scope.AccountStatus == 'checking') { 
 
\t \t \t \t \t $scope.isHideCheck = !$scope.isHideCheck; 
 
        
 
\t \t \t \t } else if ($scope.AccountStatus == 'saving'){ 
 
\t \t \t \t \t $scope.isHideSave = !$scope.isHideSave; 
 
        
 
\t \t \t \t \t } 
 
     }; 
 
\t 
 
\t });
.hideCheck{display:none} 
 
.hideSave{display:none}
