当 html 加载到 jEditPane 中时，如何修改 html 链接属性？ JDK6

我了解如何获取属性：

    e.getSourceElement().getAttributes().getAttribute(HTML.Attribute.COLOR);

如何更改该属性？

此代码更改元素的样式。希望它会有所帮助...

private void editorHyperlinkUpdate(javax.swing.event.HyperlinkEvent evt) {                                       
    if (evt.getEventType() == HyperlinkEvent.EventType.ENTERED) {
        changeStyle(evt.getSourceElement(), "a:hover");
    } else if (evt.getEventType() == HyperlinkEvent.EventType.EXITED) {
        changeStyle(evt.getSourceElement(), "a");
    }
}                                      

private void changeStyle(Element el, String styleName) {
    HTMLDocument doc = (HTMLDocument)editor.getDocument();
    StyleContext ss = doc.getStyleSheet();
    Style style = ss.getStyle(styleName);
    int start = el.getStartOffset();
    int end = el.getEndOffset();
    doc.setCharacterAttributes(start, end - start, style, false);
}
