当我尝试在 Web 上重新启动 JavaFX 应用程序(第二次调用)时，我遇到了 IE 问题。这只发生在 IE 中。 问题是我收到了两次证书通知，但我期望的是一次 ..
一个例子: 我正在做的是退出应用程序(按下按钮时)(请参阅下面的 java 代码)并在 JS 上调用 launchit ..
我的 html :
<html><head>
<script language="JavaScript" src="./web-files/dtjava.js"></script>
<script>
function launchit(){
dtjava.embed(
{
url : 'Simple_reLaunchJFX.jnlp',
placeholder : 'javafx-app-placeholder',
width : 800,
height : 600,
jnlp_content : 'PD94bWwgdmVyc2lvbj0iMS4w..........pubHA+DQo='
},
{
javafx : '2.2+'
},
{}
);
dtjava.addOnloadCallback(javafxEmbed);
}
</script>
</head><body>
<h2>__</h2>
<a href='#' onclick="launchit();">start JFX</a><br><hr><br>
<br>
<!-- Applet will be inserted here -->
<div id='javafx-app-placeholder'></div>
</body></html>
Java:
package simple_relaunchjfx;
import javafx.application.Application;
import javafx.application.Platform;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
/**
*
* @author maher
*/
public class Simple_reLaunchJFX extends Application {
@Override
public void start(final Stage primaryStage) {
Button btn = new Button();
btn.setText("Say 'Hello World'");
StackPane root = new StackPane();
root.getChildren().add(btn);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
btn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
System.out.println("Hello World!");
try {
primaryStage.close();
Platform.exit();
System.exit(0);
} catch (Exception ex) {
System.err.println("error " + ex.getMessage());
}
}
});
}
/**
* The main() method is ignored in correctly deployed JavaFX application.
* main() serves only as fallback in case the application can not be
* launched through deployment artifacts, e.g., in IDEs with limited FX
* support. NetBeans ignores main().
*
* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
请您参考如下方法:
终于解决了..
我只是在运行时通过调用动态创建另一个持有者(div)
addElement(count);
然后打电话
dtjava.addOnloadCallback(javafxEmbed);
javafxEmbed 引用了 holder div 的新 id
这将同时导致多个持有人 (div) @ ..我试图删除以前的持有人 ..但这并没有解决问题..IE 显示 2 个提示..
但这还没有结束 :) 我只是在创建调用 JavaFX 的新实例后隐藏了之前的 div
hidepreviousElement(count-1)
我将所有方法都包含在一个中:
function launchit(){
count=count+1;
addElement(count);
dtjava.addOnloadCallback(javafxEmbed);
hidepreviousElement(count-1);
}
我知道有多种方法可以添加/删除 .. 我只是使用被认为与常见浏览器 IE/FF/Chrome 兼容的方法..
