如何触发htmlunit中的keyup事件

Answer 1

package test;
import java.net.URL;

import net.sourceforge.htmlunit.corejs.javascript.ScriptableObject;
import junit.framework.TestCase;
import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.ScriptResult;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlElement;
import com.gargoylesoftware.htmlunit.html.HtmlInput;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.javascript.host.Event;
public class CopyOfTest extends TestCase {
public void testHomePage(){
try{
// 新建一个WebClient对象，此对象相当于浏览器
final WebClient webClient = new WebClient(
BrowserVersion.FIREFOX_10);
// 构造一个URL,指向需要测试的URL，如http://www.iteye.com
System.out.println("Test1");
URL url = new URL("http://www.baidu.com/");
// 通过getPage()方法，返回相应的页面
final HtmlPage page = webClient.getPage(url);
//System.out.println(page.asXml());
HtmlElement hi=(HtmlElement) page.getDocumentElement().getElementById("kw");
hi.setAttribute("value","aa");
Event event=new Event();
event.setEventType(Event.TYPE_KEY_UP);
HtmlPage hpm=hi.click(event);
hpm.toString();
System.out.println(hpm.getDocumentElement().getElementById("st").asText());
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
}
