我正在准备一个计算机展览项目,我正在为它准备网页浏览器。 它运行完美,但是当我打开google这样的网站时,它显然不清晰。将出现一个蓝色屏幕,其中包含Google徽标和一些文字。
我的代码是:
import java.awt.BorderLayout;
import java.awt.Cursor;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.*;
import javax.swing.JButton;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextField;
import javax.swing.event.HyperlinkEvent;
import javax.swing.event.HyperlinkListener;
import javax.swing.text.html.*;
public class browser
extends JFrame
implements HyperlinkListener{
URL pageURL;
private static final long serialVersionUID = 1630568393141656837L;
JPanel panel;
JButton back,forward,go;
JTextField website;
JEditorPane display;
JScrollPane sp;
public void setPanel()
{
panel=new JPanel();
back=new JButton("<<");
forward=new JButton(">>");
go=new JButton("GO");
panel.add(back);
panel.add(forward);
website=new JTextField("http://",10);
panel.add(website);
panel.add(go);
sp=new JScrollPane();
display=new JEditorPane();
display.setEditable(false);
display.setContentType("text/html");
sp.add(display);
go.addActionListener(new ActionListener(){
@Override
public void actionPerformed(ActionEvent arg0) {
// TODO Auto-generated method stub
browse();
}
});
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLayout(new BorderLayout());
add(panel,BorderLayout.NORTH);
add(display,BorderLayout.CENTER);
setSize(900,500);
setVisible(true);
}
protected void browse() {
String page=website.getText();
try {
pageURL=new URL(page);
} catch (MalformedURLException e) {
e.printStackTrace();
}
try {
display.setPage(pageURL);
} catch (IOException e) {
e.printStackTrace();
}
}
public static void main(String arg[])
{
browser br=new browser();
br.setPanel();
}
@Override
public void hyperlinkUpdate(HyperlinkEvent arg0) {
// TODO Auto-generated method stub
HyperlinkEvent.EventType event=arg0.getEventType();
if(event==HyperlinkEvent.EventType.ACTIVATED);
{
browse();
}
}
}
答案 0 :(得分:1)
您无法使用jeditorpane正确查看html页面,因为它有限制。 你只能使用编辑窗格用于基本的html。它不提供良好的CSS支持,它不支持javascript。如果你想正确显示网页,你可以使用一个好的html css和js支持库。看看lobo浏览器{ {3}}您也可以使用http://lobobrowser.org/java-browser.jsp
更新.....
这是一个示例,您可以在swing应用程序中使用javafx webView来正确查看网页。我只对代码进行了少量更改。

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLayout(new BorderLayout());
add(panel, BorderLayout.NORTH);
add(display, BorderLayout.CENTER);
setSize(900, 500);
setVisible(true);
}
private void createScene() {
PlatformImpl.startup(new Runnable() {
@Override
public void run() {
BorderPane borderPane = new BorderPane();
webComponent = new WebView();
borderPane.setCenter(webComponent);
Scene scene = new Scene(borderPane, 450, 450);
display.setScene(scene);
}
});
}
protected void browse() {
String url = website.getText();
if (url != null && url.length() > 0) {
webComponent.getEngine().load(url);
}
}
public static void main(String arg[]) {
browser br = new browser();
br.setPanel();
}
@Override
public void hyperlinkUpdate(HyperlinkEvent arg0) {
HyperlinkEvent.EventType event = arg0.getEventType();
if (event == HyperlinkEvent.EventType.ACTIVATED);
{

}
}
}
它看起来像......
