我明白了:
<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“模型”来知道是否选中了复选框(我不能使用ng-model,因为这是一个不好的做法)。所以,我正在尝试使用ng-checked。 如果我无法初始化,则ng-checked将无效。我想尝试使用ng-init,因为这是我读过的唯一内容。
我在类似的帖子中读过关于ng-init的一些内容,但我无法理解,因为我在这个世界上是如此新鲜。
“您需要使用[]表示法来访问动态属性,而不是使用。符号”
在这个例子中我该怎么做?
这是我的.Json:
$scope.dataForTheTree =[
{ "topic" : "Legislation", "children" : [
{ "subtopic" : "Education", "texto" : "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
{ "subtopic" : "HealthService", "texto" : "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
{ "subtopic" : "Assets", "texto" : " Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
{ "subtopic" : "LiquidAssets", "texto" : "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
{ "subtopic" : "Education", "texto" : "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
{ "subtopic" : "HealthService", "texto" : " Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] },
{ "subtopic" : "HealthService", "texto" : "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec vitae tincidunt mi. Donec purus ligula, tincidunt ut semper eu, laoreet.", "children" : [] }
]}];
我想将每个复选框与其子主题相关联,然后我想查看是否通过ng-checked = "{{d.subtopic}}Checkbox"
选中了复选框。
现在我的问题是"{{d.subtopic}}Checkbox"
没有初始化,这就是我需要使用ng-init的原因。
这里的问题是ng-init不理解{{}},所以我不知道如何解决这个问题:'{{d.subtopic}}Checkbox = true'
最后,我只想获得一个动态$范围,例如:
var cad = subtopic+"Checkbox";
if($scope[cad] === true){ [...]
答案 0 :(得分:0)
这是你想要实现的目标吗?
<ul id="filterList">
<div ng-repeat="data in dataForTheTree">
<li> {{data.topic}} </li>
<ul id="{{data.topic}}Son">
<li ng-repeat="d in data.children">
<input type="checkbox" ng-init='d.Checked = true' ng-model="d.Checked" />
{{d.subtopic}}
<span ng-if="d.Checked">{{d.texto}}</span>
</li>
</ul>
</div>
</ul>
还是这个?
<li ng-repeat="d in data.children">
<input type="checkbox" ng-init="$scope[d.subtopic+'Checked'] = true"
ng-model="$scope[d.subtopic+'Checked']" />
{{d.subtopic}}
<span ng-if="$scope[d.subtopic+'Checked']">{{d.texto}}</span>
</li>
