Question

我有一些css使列表看起来像树视图。我正在尝试更改当前所选li的背景，但它也将所有它的子项更改为该背景颜色。有没有办法不发生这种情况？

这是基本树结构，然后我通过代码ulScripts和ulShaders来读取文件夹结构。为了测试，我只是将Scripts li背景设置为灰色，当其他li加载时，它们也都是灰色的。

<div class="css-treeview" id="projectTree" style="display: none;">
            <ul>
                <li><input type="checkbox" id="projectRoot" /><label for="ProjectRoot" id="projectRootLabel">ProjectName</label>
                    <ul>
                        <li><input type="checkbox" id="Scripts" /><label for="Scripts">Scripts</label>
                            <ul id="ulScripts">
                            </ul>
                        </li>
                        <li><input type="checkbox" id="Shaders" /><label for="Shaders">Shaders</label>
                            <ul id="ulShaders">
                            </ul>
                        </li>
                    </ul>
                </li>
            </ul>
        </div>

Jquery选择li

$(".css-treeview li").each(function(){
                $(this).click(function(){
                    $(this).css("background-color", "gray");
                });
            });

Treeview css，我也很乐意改变它，所以如果你点击标签需要点击dbl点击它，就像现在一样扩展它。复选框部分仍然是单击
