JxBrowser

Note: Starting with Chromium 52, Backspace Navigation is disabled in the browser engine. That means that backspace navigation is no longer available in JxBrowser 6.12 and higher.(注意：从Chromium 52开始，在浏览器引擎中禁用了Backspace Navigation。这意味着JxBrowser 6.12和更高版本中不再提供退格导航。)

By default navigation on Backspace and Shift+Backspace is enabled. In order to disable navigation when user presses Backspace or Shift+Backspace use the following approach: (默认情况下，启用了Backspace和Shift + Backspace导航。为了在用户按下Backspace或Shift + Backspace时禁用导航，请使用以下方法：)

import com.teamdev.jxbrowser.chromium.Browser;
import com.teamdev.jxbrowser.chromium.DefaultLoadHandler;
import com.teamdev.jxbrowser.chromium.swing.BrowserView;

import javax.swing.*;
import java.awt.*;
