javascript - 动态变量到 angularjs ng-repeat

Question

进入第一个循环，我恢复一个 id，我尝试像这样定义其他循环:

    <ul ng-show="feed{{raterie.idFB}} === true" ng-init="var myFeed = myFeedFunction(raterie.idFB);">
        <li ng-repeat="feed in getFeeder(raterie.idFB) | limitTo:1">adoptions are : {{feed.title | cleanit}}</li>
        <li ng-repeat="feed in feeder{{raterie.idFB}} | limitTo:1">adoptions are : {{feed.title | cleanit}}</li>
        <li ng-repeat="feed in feeder{raterie.idFB} | limitTo:1">adoptions are : {{feed.title | cleanit}}</li>
        <li ng-repeat="feed in feeder[raterie.idFB] | limitTo:1">adoptions are : {{feed.title | cleanit}}</li>
        <li ng-repeat="feed in feeder['raterie.idFB'] | limitTo:1">adoptions are : {{feed.title | cleanit}}</li>
        <li ng-repeat="feed in myFeed | limitTo:1">adoptions are : {{feed.title | cleanit}}</li>
        <li ng-repeat="feed in feeder846097918756247 | limitTo:1">adoptions is : {{feed.title | cleanit}}</li>
    <ul>

我不明白如何自动构建“feeder846097918756247”。最后一个 li 是我想要得到的，我将它手动放入第一个循环中，只有一个示例

我在 $scope 中尝试了两种解决方案:

    // define the value for ng-repeat (1st solution)
    $scope.getFeeder = function(id) {
        var idr = 'feeder' + id;
        return idr;
    }
    // define the value for ng-repeat (2nd solution)
    function myFeedFunction(pId) {
        return eval('feeder' + pId) ;
    }

这行不通。

为了得到

<li ng-repeat="feed in getFeeder(raterie.idFB) | limitTo:1">adoptions are : {{feed.title | cleanit}</li>

要工作，您需要从 getFeeder 函数中的范围属性返回数组。

$scope.getFeeder = function(id) {
    return $scope['feeder' + id];
}

或者更好，而不是将 feeder846097918756247 作为属性直接放在作用域上。将各自的数据放在范围内的对象中。

即

 $scope.feeder = {};
 $scope.feeder['846097918756247'] = someArray;
//etc...

然后做:-

<li ng-repeat="feed in feeder[raterie.idFB] | limitTo:1">adoptions are : {{feed.title | cleanit}}</li>
