推荐答案

您无法通过 Applet 或 Javascript 最小化浏览器窗口.您可以尝试使用 Javascript 窗口 blur 和 focus 来查看是否可以让它们为您工作.与JS通信应该可以如下

You can't minimize a browser window from the Applet or with Javascript. You can try playing around with the Javascript window blur and focus to see if you can make them work for you. Communicating with JS should be possible as follows

import netscape.javascript.*;
import java.applet.*;
import java.awt.*;
class MyApplet extends Applet {
  public void init() {
    JSObject win = JSObject.getWindow(this);
    JSObject doc = (JSObject) win.getMember("document");
    JSObject loc = (JSObject) doc.getMember("location");

    String s = (String) loc.getMember("href");  // document.location.href
    win.call("f", null);                 // Call f() in HTML page
  }
}
