如果我有这样的 RichTextArea :
RichTextArea rta = new RichTextArea();
rta.setHTML("<p id=\"foo\">Foo</p>....<p id=\"bar\">Bar</p>");
如果我扩展 RichTextArea 类,那么编写 scrollTo() 方法的正确方法(跨浏览器)如何?
前任:
class RichTextAreaExt extends RichTextArea {
...
/**
* This method should be called only when the widget has properly been attached
* @param id String the HTML element id within the RichTextArea to scroll to
*/
public native void scrollToElement(String id) /*-{
var cWin = this.@org.foo.project.client.com.text.MyTextArea::getElement()().contentWindow;
var el = cWin.document.getElementById(id);
if (el) {
cWin.scrollTo(el.offsetLeft,el.offsetTop);
}
}-*/; ...
}
这似乎在某些浏览器中有效,但我没有要测试所有浏览器,所以欢迎输入!
谢谢!
