问题描述

我正在尝试使用聚合物纸菜单来实现上下文菜单.每当我从dom中删除节点时. polymer抛出这样的错误

I am trying to implement context menu using polymer paper menu. Whenever I remove node from dom. polymer is throwing error like this

typeError:无法在节点"上执行包含":参数1的类型不是节点"

typeError: Failed to execute 'contains' on 'Node': parameter 1 is not of type 'Node'

，我收到以下错误消息:

and I get the following error message:

我该怎么办?

推荐答案

我遇到了同样的问题.这是由于polymer-mini.html检查传递给document.documentElement.contains( node )的arg是否为节点类型.调试我可以看到一个事件传播了，所以最后一次迭代是导致此问题的窗口对象. 我的解决方案是在删除操作之前将ev.stopPropagation()添加到代码中.

I had the same issue. This is due to polymer-mini.html checks if the arg passed to document.documentElement.contains(node) is node type. Debugging i could see that an event propagated so the last iteration was window object causing this issue. My solution was adding ev.stopPropagation() to the code before removing action.
