推荐答案

是的。它能够实现小程序间的通信，如果它们是相同的页面和始发来自相同域上。您必须使用属性名称=值之类的名字在第一页的小程序：

Yes. It is possible to achieve inter-applet communication if they are on the same page and originating from the same domain. You will have to name the applets in the page first using the attribute "name=value" like:

<applet code="FirstApplet.class" name="firstApplet" width=nn height=nn></applet>
<applet code="SecondApplet.class" name="secondApplet" width=nn height=nn></applet>

以上到位，FirstApplet.java，使用以下方法来访问SecondApplet：

with above in place, in FirstApplet.java, use the following to access SecondApplet:

SecondApplet secondApplet =
         (SecondApplet)getAppletContext().getApplet("secondApplet");
//invoke a method on secondApplet here

同样，您可以访问FirstApplet在SecondApplet.java

Similarly, you can access the FirstApplet in SecondApplet.java
