如何从嵌套的XUL树中删除项目? [英] How can I delete item from a nested XUL tree?

问题描述

我使用XUL创建了一个嵌套树(没有数据库用于存储项目).我想通过选择项目(一次仅1个)从该树中删除项目，然后单击删除".我编写了要删除的Javascript函数，如下所示，但它不起作用.

I created a nested tree using XUL (no database was used to store items). I want to delete items from this tree by selecting the item (only 1 at a time) then click delete. I wrote Javascript function to delete as following but it does not work.

function delete(){
  var tree = document.getElementById("treeId");    
  currentPos = tree.currentIndex;    
  var currentItem = tree.contentView.getItemAtIndex(currentPos);
  var parent = currentItem.getParent();
  parent.removeChild(currentItem);
}

我猜getParent()不是正确的方法，但是没有找到任何其他方法.有人可以给我一些提示吗? 谢谢

I guess getParent() is not the right method but did not find any other method. Can someone give me some hints please. Thanks

推荐答案

问题已解决.是我的错我只是意识到删除不能用作函数的名称.

Problem solved. It was my mistake. I just realized that delete cannot be used as a name of function.
