ng-repeat 嵌套 ng-switch 出错解决

Missing Required Controller

Controller 'ngSwitch', required by directive 'ngSwitchWhen', can't be found!

<div class="item" ng-repeat="item in list">
    <!--0表进行中，1表已提车， 2表待结账-->
    <div ng-switch="item.state.value">

    　　<div ng-switch-when="0" class="ui top right attached label yellow">服务中</div>
    　　<div ng-switch-when="1" class="ui top right attached label red">已结账</div>
    　　<div ng-switch-when="2" class="ui top right attached label orange">待结账</div>
    　　<div ng-switch-default class="ui top right attached label">已挂账</div>
    </div>
</div>

ng-repeat每个循环都会创建一个scope

修改为：

<div class="item" ng-repeat="item in list" ng-switch="item.state.value">
    <!--0表进行中，1表已提车， 2表待结账-->

    <div ng-switch-when="0" class="ui top right attached label yellow">服务中</div>
    <div ng-switch-when="1" class="ui top right attached label red">已结账</div>
    <div ng-switch-when="2" class="ui top right attached label orange">待结账</div>
    <div ng-switch-default class="ui top right attached label">已挂账</div>
</div>

AngularJS ng-repeat下使用ng-model

<table>
<tr ng-repeat="row in collections">
<td>
{{row.name}}: <input type="radio" value="{{row.value}}" ng-model="selectValue"/>
</td>
</tr>
</table>

当你书写了上述代码后。你会发现点击其中的对话框，$scope.selectValue中并没有保存你选中的对应单选框的值。

这是因为处在ng-repeat之间的代码，对全局的$scope里变量的内容是不可见的，而是为ng-repeat创建的子scope里面的。

所以要引用ng-repeat $scope里的成员，你可以使用$parent

<table>
<tr ng-repeat="row in collections">
<td>
{{row.name}}: <input type="radio" value="{{row.value}}" ng-model="$parent.selectValue"/>
</td>
</tr>
</table>
