Note: Advice in this article will only work for JxBrowser 6. See the corresponding article for JxBrowser 7 here.(注意:本文中的建议仅适用于JxBrowser6,JxBrowser7相应文章请点击这里。)
JxBrowser provides API for working with navigation history. Using this API you can get information about navigation entries, got to entry at specified index, remove navigation entries, etc.(JxBrowser提供用于处理导航历史记录的API。使用此API,您可以获取有关导航条目的信息,到达指定索引的条目,删除导航条目等。)
Note: When you create Browser instance it navigates to the about:blank web page by default, so there's always one entry in navigation history.(注意:创建浏览器实例时,默认情况下它会导航到about:blank网页,因此导航历史记录中始终只有一个条目。)
Receiving navigation entry count(接收导航条目计数)
Returns the number of entries in the back/forward list. (返回后退/前进列表中的条目数。)
int entryCount = browser.getNavigationEntryCount();
Index of the current navigation entry(当前导航条目的索引)
Returns index of the current navigation entry in the back/forward list. (返回后退/前进列表中当前导航条目的索引。)
int index = browser.getCurrentNavigationEntryIndex();
Navigating to the entry at index(导航到索引处的条目)
Navigates to the entry at a specific index in the back/forward list. (导航到后退/前进列表中特定索引处的条目。)
browser.goToIndex(index);
Removing the entry at index(删除索引处的条目)
Removes navigation entry from the back/forward list at a specific index. (从特定索引的后退/前进列表中删除导航条目。)
boolean success = browser.removeNavigationEntryAtIndex(index);
Getting information about navigation entry(获取有关导航条目的信息)
Prints information about the navigation entry at specific index. (在特定索引处打印有关导航条目的信息。)
NavigationEntry navigationEntry = browser.getNavigationEntryAtIndex(index); System.out.println("URL = " + navigationEntry.getURL()); System.out.println("Original URL = " + navigationEntry.getOriginalURL()); System.out.println("Title = " + navigationEntry.getTitle());
Clearing entire navigation history(清除整个导航记录)
import com.teamdev.jxbrowser.chromium.Browser; import com.teamdev.jxbrowser.chromium.Callback; import com.teamdev.jxbrowser.chromium.swing.BrowserView; import javax.swing.*; import java.awt.*; /** * The sample demonstrates how to clear entire navigation history. */ public class ClearHistorySample { public static void main(String[] args) { Browser browser = new Browser(); BrowserView view = new BrowserView(browser); JFrame frame = new JFrame(); frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); frame.add(view, BorderLayout.CENTER); frame.setSize(800, 600); frame.setLocationRelativeTo(null); frame.setVisible(true); loadURLAndWaitReady(browser, "http://www.google.com"); loadURLAndWaitReady(browser, "http://www.teamdev.com"); // Returns the number of entries in the back/forward list. int entryCount = browser.getNavigationEntryCount(); // Remove navigation entries at index. for (int i = entryCount - 2; i >= 0; i--) { boolean success = browser.removeNavigationEntryAtIndex(i); System.out.println("Navigation entry at index " + i + " has been removed successfully? " + success); } } private static void loadURLAndWaitReady(Browser browser, final String url) { Browser.invokeAndWaitFinishLoadingMainFrame(browser, new Callback<Browser>() { @Override public void invoke(Browser value) { value.loadURL(url); } }); } }
