我在我的扩展程序中的html页面添加了一个applet。以下代码行引发了一个异常:
try {
document.Applet.isActive();
}
catch(e) {
setTimeout(doingSomeThing(),200);
return;
}
错误:尝试在没有invokeDefault方法的对象上调用默认方法
过了一会儿:
TypeError:document.Applet.isActive不是函数
我正在测试不同操作系统和firefox版本的扩展以进行部署。在运行Java 1.6.0_22的Mac OS X计算机上的Firefox 4.0上发生了上述错误。
它在Mac OS X上使用Java版本1.6.0_24进行了测试,并且运行正常。
有关于此的任何想法吗?
更新:我在1.6.0_22附加了Java控制台输出
