AngularJS：TypeError：无法读取未定义的属性“childNodes”

Question

I have a controller inside which I have two toggle buttons to display the view accordingly. The two types of view that are shown in the controller are controlled by the $scope.isStore variable which is the deciding factor in the html part.

But once I toggle the part that is supposed to be changed becomes blank and I get the following error.

angular.js:13424 TypeError: Cannot read property 'childNodes' of undefined

at controllersBoundTransclude (angular.js:9072)
at ngIfWatchAction (angular.js:25323)
at Scope.$digest (angular.js:16869)

I tried looking for solutions but none worked for me. Even when setting a setTimeout function when changing the $scope variable gives the same output.

HTML Part :

        <div id="go-pro" class="storeCoins" ng-if="isPremiumUser==true">
            <span class="coinText">you are Premium User</span>
            <img class="imgPro"  id="feature" ng-src="/app/app_resources/icons/pirate_girl.png" />
        </div>


            <table id="links" class="tab-selector">
                <tr>
                    <td class="tablinks" ng-class="{highlighwallet: isStore==true}" ng-click="walletController.showStore(event)">STORE</td>
                    <td class="tablinks" ng-class="{highlighwallet: isStore==false}" ng-click="walletController.showHistory(event)">TASK HISTORY</td>
                </tr>
            </table>



            <div ng-if="isStore==false">
                <ul>
                    <li class="taskList" ng-click="arbit()">
                        <div class="taskHistoryList" ng-repeat="taskList in mergedTransaction | orderBy:'-Date'">
                            <img  class="taskListImage" ng-src="{{walletController.getImage(taskList)}}">
                            <span ng-show="isCoinBought">{{ taskList.coin_value}}</span>
                        </div>
                    </li>
                </ul>
            </div>


            <div ng-if="isStore==true">
                <packgroup-directive>
                </packgroup-directive>
                 <div ng-controller="WalletController">
                   <outfit-directive></outfit-directive>
                 </div>
                   <h3>GO PRO</h3>
                <div id="go-pro" ng-if="isPremiumUser==false">
                    <img class="feature" ng-click="walletController.onGoPremiumChosen()" id="feature" ng-src="/app/app_resources/language/en/resources/banner.jpg" />

                </div>

            </div>
        </div>

JS Part :

walletModel.showStore = function () {
        console.log("ShowStore")
          $scope.isStore = true;
          $scope.$apply();
    }

Do you know difference between ng-if and ng-show ?

ng-if do not create element when its value is false,

and ng-show active just like hidden .

So to fix your problem, I think, you should have to change ng-if to ng-show or control this in '.js'
