AngularJs : Show Hide Fields According Select Value

Question

I want to show hide form fields on the basis of Select Value. e.g my form has 5 text fields and 1 select option field In those fields 4 fields are depended on select value. if i select cloth then cloth type and cloth value remains, lether type and lether value hide. but when i select Bags lether type and lether value remain else hide. i am trying some condition and ng-class="{'hideCheck': isHideCheck}" model but it behaving abnormally.

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

	app.controller('appCont', function($scope) { 
	
			$scope.ProductTypeChnaged = function () {
            $scope.ProductStatus = $scope.ProductValue;
			
			if ($scope.AccountStatus == 'checking') {
					$scope.isHideCheck = !$scope.isHideCheck;
				} else if ($scope.AccountStatus == 'saving'){
					$scope.isHideSave = !$scope.isHideSave;
					}
        };
	
	});

.hideCheck{display:none}
.hideSave{display:none}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<div ng-app="mainApp" ng-controller="appCont">
<p>Product box status: {{ ProductStatus }}</p>

Answer 1

use ng-hide to hide the element. ng-class is used to alter css.

I changed your code, it will hide element valus and type when option checking is selected, just an example for you, not implement your feather. you would like to read https://docs.angularjs.org/api/ng/directive/ngHide.

by the way , ng-repeat is a good way to do table things.

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

	app.controller('appCont', function($scope) { 
	
			$scope.ProductTypeChnaged = function () {
            $scope.ProductStatus = $scope.ProductValue;
			
			if ($scope.AccountStatus == 'checking') {
					$scope.isHideCheck = !$scope.isHideCheck;
                    
				} else if ($scope.AccountStatus == 'saving'){
					$scope.isHideSave = !$scope.isHideSave;
                   
					}
        };
	
	});

.hideCheck{display:none}
.hideSave{display:none}
