我有一个简单的ng-repeat-start和ng-repeat-end。在ng-repeat中,我有一个ng-click。如何在ng-click中使用ng-repeat-start中的$ index来显示/隐藏ng-show。
HTML:
<ul>
<li ng-repeat="data in MyData track by $index">
<p>Show me my {{ data }}</p>
</li>
<li>
<div>
<p>Select</p>
<span ng-click="{{'showHidden'+$index = !'showHidden'+$index}}"></span>
</div>
<div>
<p ng-show="{{'showHidden'+$index}}">My hidden content, my hidden content, my hidden content, my hidden content, my hidden content, my hidden content </p>
</div>
</li>
<li ng-repeat-end>
<p>{{ data.name }}</p>
<p>{{ data.age}}</p>
</li>
</ul>
基本上我拥有的是:
ng-click="{{'showHidden'+$index = !'showHidden'+$index}}"
ng-show="{{'showHidden'+$index}}"
其中$ index由父ng-repeat-start

您可以初始化临时变量以跟踪可见性布尔值(我只是将其称为“可见”)。 ng-repeat的每个循环都有自己的$ scope,因此新变量被约束到$ scope。

<div ng-controller="MyCtrl">
<ul>
<li ng-repeat-start="data in MyData track by $index" ng-init="visible = false">
<p>Show me my {{ data }}</p>
</li>
<li>
<div>
<p>Select</p>
<a href="" ng-click="visible = !visible">*</a>
</div>
<div>
<p ng-show="visible">My hidden content, my hidden content, my hidden content, my hidden content, my hidden content, my hidden content </p>
</div>
</li>
<li ng-repeat-end>
<p>{{ data.name }}</p>
<p>{{ data.age}}</p>
</li>
</ul>
</div>
