無法與Internet Explorer第二次（重新啓動）啓動JavaFX Web應用程序

當我嘗試重新啓動Web上的JavaFX應用程序（用於第二次調用）時，IE瀏覽器遇到問題..這種情況只發生在IE .. 問題是，我得到通知，證書兩次，但我想到的是一個..無法與Internet Explorer第二次（重新啓動）啓動JavaFX Web應用程序

的一個樣本：什麼我做的是從應用程序退出（按下按鈕時）（見下面的java代碼），並調用launchit上JS ..

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>

的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); 
    } 
}

最後我解決吧..

我只是創建另一個持有人（格）上動態運行時通過調用

addElement(count);

，並呼籲

dtjava.addOnloadCallback(javafxEmbed);

javafxEmbed引用了持有者div的新ID

這將導致多個持有人（股利）@同時..我試圖刪除以前的持有人..但這並不能解決問題..用IE它顯示2提示..

但那不是結束:)我只是藏在前面的div創建的JavaFX的新實例後調用

hidepreviousElement(count-1)

我包括一個所有方法：

function launchit(){ 
    count=count+1; 

    addElement(count); 
    dtjava.addOnloadCallback(javafxEmbed); 
    hidepreviousElement(count-1); 
    }

我知道有變異方法如何添加/刪除..我只是使用什麼考慮要與常見的瀏覽器IE/FF/Chrome瀏覽器兼容..

<html><head> 

<script language="JavaScript" src="./web-files/dtjava.js"></script> 

<script> 

var count=1; 
    function javafxEmbed() { 
     dtjava.embed(
      { 
       url : 'Simple_reLaunchJFX_1_002.jnlp', 
       placeholder : 'javafx-app-placeholder'+count, 
       width : 800,
