小程序间通信 [英] Inter applet communication

问题描述

在我的理解中，每个小程序都是独立的实体.有没有可能小程序间通信 ?.如果是这样，如何实现?

In my understanding each applets are independent entities . Is it possible to have inter applet communication ? . If so , how it could be achieved ?

谢谢J

推荐答案

是的.如果它们在同一页面上并且来自同一域，则可以实现小程序间通信.您必须首先使用属性name=value"命名页面中的小程序，例如:

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>

在上面的地方，在 FirstApplet.java 中，使用以下内容访问 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

同理，可以在SecondApplet.java中访问FirstApplet

Similarly, you can access the FirstApplet in SecondApplet.java
