需求：页面有一个使用ng-repeat指令生成的列表，当点击一个item时，就隐藏之。
问题：请问如何在ng-click的回调中操作当前item的ng-show的值，而不影响其他item？

<ul ng-controller="listCtrl">
<li ng-repeat="item in items" ng-click="delete()" ng-show="show">
<span ng-bind="item.title"></span>
<span ng-bind="item.price"></span>
</li>
</ul>
<script>
var myApp = angular.module('myApp',[]);
myApp.controller('listCtrl',function($scope){
var items = [{title:"title1",price:120},{title:"title2",price:23},{title:"title3",price:32234}]
$scope.items = items;
// $scope.show = "true";
$scope.delete = function(item){
// $scope.show = "false"
}
})

设置一个hidden属性，结合列表的$index即可。
<ul ng-controller="listCtrl">
<li ng-repeat="item in items" ng-click="change($index)" ng-hide="hidden.value == $index">
<span>{{item.title}}</span>
<span ng-bind="item.price"></span>
</li>
</ul>angular.module('myApp',[])
.controller('listCtrl',function($scope){
var items = [{title:"title1",price:120},{title:"title2",price:23},{title:"title3",price:32234}]
$scope.items = items;
$scope.hidden = {value: null}
// $scope.show = "true";
$scope.change = function(i) {
$scope.hidden.value = i;
}
})之所以要把hidden设置为对象而非原始值，是因为ng-repeat有独立的作用域，直接在ng-repeat的作用域上修改原始值父控制器上的值是不会改变的；需要借助引用类型，如对象或数组，才能保证修改保存到父级控制器。

@onelove 这哥们儿的回答应该是这个意思：
<ul ng-controller="listCtrl">
<li ng-repeat="item in items" ng-click="delete(item)" ng-show="item.show">
<span ng-bind="item.title"></span>
<span ng-bind="item.price"></span>
</li>
</ul>
<script type="text/javascript">
var myApp = angular.module('myApp',[]);
myApp.controller('listCtrl',function($scope){
var items = [{title:"title1",price:120,show:true},{title:"title2",price:23,show:true},{title:"title3",price:32234,show:true}]
$scope.items = items;
$scope.delete = function(item){
item.show = false;
}
})
</script>
这样虽然能实现需求，但是问题很大，就是把控制视图的show和数据耦合在一起了，这样不好吧？还有什么办法么？
