如何在contenteditable div中过滤用户粘贴的内容？

Question

我有一个允许contenteditable的div。

<div contenteditable="true">
</div>

我想过滤所有html标签copy＆amp;从用户粘贴（除外），如何在Dart代码中实现？

Answer 1

myDiv.onPaste.listen((e) {
  // do filtering here and then insert the result imperatively
  // one or both of the following might be necessary to prevent
  // the default paste behavior happening as well.
  e.preventDefault();
  e.stopPropagation();
});
