单击引导程序4列表组面板父项时将URL片段附加到URL

bootstrap-4

<a href="node##" ...></a> 引用HTML id list-group-item 节点?

例如,如果我单击“园艺”列表组项,它将展开,显示其下的项,但我也希望同时将 #node11

期望结果

如果当前页是 http://www.example.com/home/ . 当我单击“园艺”菜单项时,菜单将展开,URL将更改为 http://www.example.com/home/#node11 http://www.example.com/home/#node13 . 因此,URL会在 列表组项 已单击具有子项的项。

我发现的一个解决方案是像这样使用javascript:

<script>
    $('.list-group').on('click', '.list-group-item', function () {
        var clickedID = this.id;
        window.location.hash = clickedID;
        alert(clickedID);
    });
</script>

        window.location.hash = clickedID;
        alert(clickedID);
    });
</script>

带走 :当其中一个链接 list-group-item 已单击。在这种情况下,我必须添加一个独特的 id 列表组项

下一步

if(window.location.hash) {
    var hash = window.location.hash.slice(1);
    var elem = document.getElementById(hash);
    var node = elem.hash.slice(1);
    var x = document.getElementById(node);
    x.classList.add('show');
} else {
  // Fragment doesn't exist
}
