Question

这里的目的是根据我的偏好显示或隐藏下面的div元素

<div ng-repeat="data_training in data.training track by $index">
                                        <h4 ng-hide="data_training.list == [] && data_training.note == '' ">WHAT TYPE OF TRAINING IS REQUIRED TO START THIS VENTURE</h4> 
                                        {{data_training.note}}
                                            <ul ng-repeat="data_training_lists in data_training.list track by $index ">
                                                <li>
                                                    {{data_training_lists}}
                                                </li>
                                            </ul>
                                    </div>

这只是我的index.html的片段，下面是我的json数据的片段

 "training": [
      {
        "note": "",
        "list": [
          "Agricultural extension officers ",
          "Agricultural shops ",
          "Non Government Organisations, Community Based Organisations ",
          "Other farmers "
        ]
      }
    ],

想要显示h4元素，如果只有training.note或training.list对它们有价值。感谢提前

Answer 1

检查长度＆gt; 0：

<h4 ng-hide="data_training.list.length && data_training.note.length">WHAT TYPE OF TRAINING IS REQUIRED TO START THIS VENTURE</h4>

Answer 2

试试这个

<h4 ng-if="data_training.list.length && data_training.note.length">WHAT TYPE OF TRAINING IS REQUIRED TO START THIS VENTURE</h4>

或ng-show

<h4 ng-show="data_training.list.length && data_training.note.length">WHAT TYPE OF TRAINING IS REQUIRED TO START THIS VENTURE</h4>

或ng-hide

<h4 ng-hide="data_training.list.length && data_training.note.length">WHAT TYPE OF TRAINING IS REQUIRED TO START THIS VENTURE</h4>

我更喜欢使用ng-if而不是ng-show

ng-if指令从页面中删除内容 ng-show / ng-hide使用CSS显示属性隐藏内容。

如何使用ng-hide基于angularjs中的特定条件仅显示选定的div元素
