在rightside.component.html中,我有一些按钮,它们基本上列出了右侧的项目。类似于我发现的这个plunkr的东西:

我必须多次单击(在屏幕上其他地方或按钮本身)才能将其隐藏。如果我从底部按钮开始,然后转到列表的顶部,它只需单击一下即可工作。由于某些原因,这些按钮在单击一次后就无法工作

我在控制台中看不到任何错误,我想知道是否可以采取任何措施来避免这种错误行为。我想隐藏发生与所有按钮的单键点击,当按任何顺序点击


感谢您的帮助。

而不是
item.selected=false您应该重新分配项,因此请尝试
项={…项,selected:false}我已经更新了问题并添加了TreeNode.ts代码。执行此操作时,我可以看到此错误:类型“{selected:false;displayName:string;children:TreeNode[];collapsed?:boolean;indete…”不可分配给类型“TreeNode”。类型“{selected:false;displayName:string;children:TreeNode[];collapsed?:boolean;indete…”中缺少属性“getValue”。
