Question

我制作了一个指令，当点击“了解更多”时，它将滚动到隐藏的下拉列表。它似乎只在你已经打开后单击“隐藏”时滚动到div。

如何让它在首次下降时滚动？

滚动指令

app.directive('scrollToItem', function() {                                              
return {

};
});

App JS

var app = angular.module('app', ['ui.bootstrap', 'ngRoute', 'ngAnimate']);

app.config(function($interpolateProvider, $routeProvider) {
$interpolateProvider.startSymbol('[[');
$interpolateProvider.endSymbol(']]');

$routeProvider

.when('/', {
  templateUrl : 'pages/LandingPage.html',
  controller : 'LandingCtrl'
})
.otherwise({ redirectTo: '/signin'});
});

AngularJs - Scroll Top指令仅在隐藏div时滚动，而不是在打开时滚动
