java - 从 javascript 触发小程序按钮

Question

我想使用 javascript 在单击普通 html 按钮时触发小程序按钮

public class appletToWrite extends Applet{
Button write;
static String msPath;
static String msData;
public appletToWrite()
{
    this.write = new Button("Save");
}

public static void initializeData(String asPath, String asData){
    msPath = asPath;
    msData = asData;
}

public void init() { 
    add(this.write, "Center");
    this.write.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent paramActionEvent) {
            foo();
        }
    }); }


public void foo(){
    new appletToWrite.WriteText();
}

public class WriteText {
    WriteText() {
        try {
            String str2 = "D:\\Documents and Settings\\varun.aggarwal\\Desktop\\sample\\wow.htm";
            File localFile = new File(str2);
            localFile.createNewFile();
            BufferedWriter localBufferedWriter = new BufferedWriter(new FileWriter(localFile, true));
            String str1="helllllllo";
            localBufferedWriter.write(str1);
            localBufferedWriter.close();
            JOptionPane.showMessageDialog(null, "File Successfully Saved!!! ");

        }
        catch (Exception localException) {
            JOptionPane.showMessageDialog(null, localException.getMessage());
        }
    }
}

这可能吗？？？

这与权限有关，因为我发现文件 IO 权限仅在我单击小程序按钮时可用，而不是在我单击 html 按钮并调用小程序方法 foo 时可用

是的，JavaScript 到 Applet 和 Applet 到 Javascript 都是可能的。
