How to implement in JEditorPane on text changed

Question

如何在JEditorPane中实现文本更改方法（在添加或删除的每个字符上获取文本）？

Answer 1

You need to register a document listener with the document of the JEditorPane which will be notified when text is inserted or removed or when the text style changes.

Take a look at Java Tutorial > How to Write a Document Listener for more information about document listeners and document events.
