我正在尝试使用ng-switch.

我在我的 Ctrl (流)中设置选项卡并跟踪当前选择的选项卡:

app.controller("StreamCtrl", function($scope) {
$scope.streams = [{
    title: 'latest',
    icon: 'time',
    data: "Hi, I'm data."
}, {
    title: 'popular',
    icon: 'fire',
    data: "Hi, I'm data too!"
}];

$scope.selection = $scope.streams[0];

$scope.getCurrentStreamIndex = function(){
    // Get the index of the current stream given selection
    return $scope.streams.indexOf($scope.selection);
};

// Go to a defined stream index
$scope.goToStream = function(index) {
    if($scope.streams[index]) {
        $scope.selection = $scope.streams[index];
    }
};
});

在我看来(index.html),我使用 ng-repeat 为每个选项卡创建一个容器:

<section class="streams" ng-controller="StreamCtrl" ng-switch="stream.title == selection.title">
        <section class="stream" ng-switch-when="true" ng-repeat="stream in streams">
            {{stream.title}}
            <div class="loaderContainer"><div class="loader"></div></div>
        </section>
    </section>

我遇到的问题是我的 ng-switch-when 语句,因为它不接受表达式。

如果我可以设置ng-switch-when="{{stream.title}}",那么我相信我可以使用ng-switch="selection.title",一切都会好起来的。

我将如何构建ng-switch表达式以匹配动态生成的列表?

新的html:

  <div ng-controller="StreamCtrl">
  <section class="streams"  ng-repeat="stream in streams">
        <section class="stream">
            {{stream.title}}
            <div class="loaderContainer" ng-show="stream == selection"><div class="loader">SELECTED</div>
        </section>
    </section>
  </div>
