独家选择列表中的元素

Question

我有我自己的无序列表：

<ul> 
    <li ng-class="{ 'active': selected }" ng-click="selected = !selcted">Stuff 1</li> 
    <li ng-class="{ 'active': selected }" ng-click="selected = !selcted">Stuff 2</li> 
    <li ng-class="{ 'active': selected }" ng-click="selected = !selcted">Stuff 3</li> 
</ul> 

我想要一类适用于用户选择列表项。一次只有一个项目可以拥有该课程。什么是最好的方法来解决这个问题？大约有十几个元素，所以我宁愿不为每个项目声明一个新的变量。

Answer 1

设置每个项目的属性：

<ul> 
    <li ng-class="{ 'active': selected == 1 }" ng-click="selected = 1">Stuff 1</li> 
    <li ng-class="{ 'active': selected == 2 }" ng-click="selected = 2">Stuff 2</li> 
    <li ng-class="{ 'active': selected == 3 }" ng-click="selected = 3">Stuff 3</li> 
</ul> 

Answer 2

如果你想角上下的使用NG-repat

HTML

<ul ng-repeat="s in stuffs"> 
    <li ng-class="{active:$index==selected}" ng-click="selected=$index">{{s}}</li> 
</ul> 

JS

$scope.stuffs = ['Stuff 1', 'Stuff 2', 'Stuff 3'];
