Question

我知道了：

<ul id="filterList">
      <div ng-repeat="data in dataForTheTree">
         <li> {{data.topic}} </li>
          <ul id={{data.topic}}Son>
              <li ng-repeat="d in data.children>  
                 <input type="checkbox" ng-init='{{d.subtopic}}Checkbox = true' ng-checked = "{{d.subtopic}}Checkbox"/>{{d.subtopic}}
              </li>
          </ul>
      </div>
</ul>

我需要创建一个 "model" 来知道复选框是否被选中（我不能使用 ng-model，因为这是一种不好的做法）。所以，我正在尝试使用 ng-checked。如果我不能初始化它，ng-checked 将不起作用。我想尝试使用 ng-init，因为这是我唯一读到的内容。

我在类似的地方读过一些关于 ng-init 的文章 post，但我无法理解，因为我对这个世界太陌生了。

"You need to access dynamic properties using [] notation instead on . notation"

在这个例子中我该怎么做？

这是我的。Json:

$scope.dataForTheTree =[
  { "topic" : "Legislation", "children" : [
      { "subtopic" : "Education", "texto" : "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
      { "subtopic" : "HealthService", "texto" : "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
      { "subtopic" : "Assets", "texto" : " Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
      { "subtopic" : "LiquidAssets", "texto" : "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
      { "subtopic" : "Education", "texto" : "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
      { "subtopic" : "HealthService", "texto" : " Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
      { "subtopic" : "HealthService", "texto" : "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] }
]}];

我想 link 每个复选框都有他的子主题，然后我想看看复选框是否通过 ng-checked = "{{d.subtopic}}Checkbox" 被选中。

现在我的问题是 "{{d.subtopic}}Checkbox" 没有初始化，这就是我需要使用 ng-init 的原因。

这里的问题是ng-init不理解{{}}，所以不知道怎么解决：'{{d.subtopic}}Checkbox = true'

最后我只想得到一个动态的 $scope，例如：

var cad = subtopic+"Checkbox";

  if($scope[cad] === true){ [...]

Answer 1

这是您要实现的目标吗？

<ul id="filterList">
  <div ng-repeat="data in dataForTheTree">
    <li> {{data.topic}} </li>
    <ul id="{{data.topic}}Son">
      <li ng-repeat="d in data.children">
        <input type="checkbox" ng-init='d.Checked = true' ng-model="d.Checked" />
        {{d.subtopic}}
        <span ng-if="d.Checked">{{d.texto}}</span>
      </li>
    </ul>
  </div>
</ul>

或者这个？

    <li ng-repeat="d in data.children">
      <input type="checkbox" ng-init="$scope[d.subtopic+'Checked'] = true" 
          ng-model="$scope[d.subtopic+'Checked']" />
      {{d.subtopic}}
      <span ng-if="$scope[d.subtopic+'Checked']">{{d.texto}}</span>
    </li>
