我有一些内容和一些链接。我在这里使用 scrollspy。每当我单击一个链接时，它会滚动到特定的 div 和菜单将处于事件状态。但是这里不是滚动，而是我需要隐藏其他 div 并显示特定/匹配的 div。我的意思是这里我需要隐藏和显示内容而不是滚动.这是更新后的代码 https://plnkr.co/edit/VvV7T0FCdXirQfMROwi2?p=preview

最佳答案
您需要为每个 div 设置可见性，然后根据链接点击切换它...为此，我们需要将每个对象的可见性状态存储在我们的 $scope.groups数组。我们通过在数组的每个对象中引入一个新变量visible来做到这一点，我们默认为我们需要显示的对象将其设置为true - 其余的可以在点击链接后显示顶。
检查下面的工作演示:
var app = angular.module('app', ['ui.bootstrap', 'ngSanitize', 'angular.filter']);
app.controller('AccordionDemoCtrl', function($scope, $location, $anchorScroll) {
$scope.oneAtATime = true;
$scope.visibleGrid=-1;
$scope.gotoDiv = function(x) {
$scope.visibleGrid=x;
$scope.groups.forEach(a => {
/* console.log(" we got ID:" + x + " & looking it against the ID:" + a.id); */
a.isOpen = true;
});
};
$scope.groups = [{
title: 'title 0',
id: '0',
list: ['<i>item1a</i> blah blah',
'item2a',
'item3a',
'item4a',
'item5a',
'item6a',
'item7a'
]
},
{
title: 'title 1',
id: '1',
list: ['<i>item1a</i> blah blah',
'item2a',
'item3a',
'item4a',
'item5a',
'item6a',
'item7a'
]
},
{
title: 'title 2',
id: '2',
list: ['<i>item1a</i> blah blah',
'item2a',
'item3a',
'item4a',
'item5a',
'item6a',
'item7a'
]
},
{
title: 'title 3',
id: '3',
list: ['<i>item1a</i> blah blah',
'item2a',
'item3a',
'item4a',
'item5a',
'item6a',
'item7a'
]
},
{
title: 'title 4',
id: '4',
list: ['<i>item1a</i> blah blah',
'item2a',
'item3a',
'item4a',
'item5a',
'item6a',
'item7a'
]
},
{
title: 'title 5',
id: '5',
list: ['<i>item1a</i> blah blah',
'item2a',
'item3a',
'item4a',
'item5a',
'item6a',
'item7a'
]
}
];
$scope.groups[0].isOpen = true;
