我正在尝试使用ng-switch来组合一种选项卡式菜单。
我在我的Ctrl (streams)中设置了标签,并将当前选择的标签记录为selection:
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];
}
};
});在我的视图(index.html)中,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。
我如何构造一个ng-switch表达式来匹配动态生成的列表呢?

好了,看看这个,我认为它应该给你足够的继续下去的能力:
