我很少有链接和来自ng repeat的div。当我单击任何链接时，它将去/滚动到相同id的相同div。这很好，但是在这里我需要基于id扩展div。我单击任何链接，只有那些div应该扩展其他div才仍然折叠。.soon。我尝试了基于id进行操作，但无法正常工作，有人可以帮我提供下面的代码，以及关于plunker的更新演示 https://plnkr.co/edit/MRZgVHYMWsff022Mq3dV?p=preview

要实现此目的，您可以再添加1个条件（if (a.id === x.toString())）来检查gotoDiv函数中的选定div，如下所示：
$scope.gotoDiv = function (x) {
if (x) {
$scope.groups.forEach(a = > {
if (a.id === x.toString()) {
a.isOpen = true;
}
});
}
else {
a.isOpen = false;
}
};
