在另一个函数内初始化时，Bootstrap Carousel不可见

Question

我正在使用angular and bootstrap ui并试图让bootstrap轮播工作。目前我只是使用文档中提供的演示代码。如果我在页面加载后立即初始化该函数，它就可以正常工作。

然而，我的最终目标是传递一个变量，直到用户输入一些信息后才会定义，所以我需要稍后初始化轮播。当我尝试这样做时，我在控制台中没有出现任何错误，当我检查html时，它显示已经将旋转木马插入到DOM中。然而，它的任何部分都没有出现。我只是得到一个空白页面。 任何帮助将不胜感激。谢谢！

HTML：

$scope.carousel = function(totalMatches){ 


    console.log("called");
    console.log(totalMatches);

    $scope.myInterval = -1;
    var slides = $scope.slides = [];
        $scope.addSlide = function() {
            var newWidth = 600 + slides.length + 1;
            slides.push({
            image: 'http://placekitten.com/' + newWidth + '/300',
            text: ['More','Extra','Lots of','Surplus'][slides.length % 4] + ' ' +
            ['Cats', 'Kittys', 'Felines', 'Cutes'][slides.length % 4]
            });
         };
            for (var i=0; i<4; i++) {
              $scope.addSlide();
             }

};


    $scope.carousel(totalMatches);

JS（工作）：

$scope.findSomething = function(){

    do some stuff in here to define totalMatches

    $scope.carousel(totalMatches);
};

$scope.carousel = function(totalMatches){ 


    console.log("called");
    console.log(totalMatches);

    $scope.myInterval = -1;
    var slides = $scope.slides = [];
        $scope.addSlide = function() {
            var newWidth = 600 + slides.length + 1;
            slides.push({
            image: 'http://placekitten.com/' + newWidth + '/300',
            text: ['More','Extra','Lots of','Surplus'][slides.length % 4] + ' ' +
            ['Cats', 'Kittys', 'Felines', 'Cutes'][slides.length % 4]
            });
         };
            for (var i=0; i<4; i++) {
              $scope.addSlide();
             }

};
