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

[英]AngularJS : TypeError: Cannot read property 'childNodes' of undefined

我有一个控制器,里面有两个切换按钮来相应地显示视图。 控制器中显示的两种类型的视图由$scope.isStore变量控制,该变量是html部分的决定因素。

但是一旦我切换应该更改的部分就变成空白,并且出现以下错误。

angular.js:13424 TypeError: Cannot read property 'childNodes' of undefined
at nodeLinkFn (angular.js:9017)
at compositeLinkFn (angular.js:8333)

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

我尝试寻找解决方案,但没有一个对我有用。 即使在更改 $scope 变量时设置setTimeout函数也会给出相同的输出。

HTML 部分:

        <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部分:

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

你知道ng-ifng-show之间的区别吗?

ng-if当元素值为 false 时不创建元素,

ng-show active 就像hidden

因此,要解决您的问题,我认为您应该将ng-if更改为ng-show或在 '.js' 中控制它
