How to send JavaScript variables to Java applet?

推荐答案

您的小程序应该有一个公共的方法，例如receiveData的（）：

Your applet should have a public method , for example receiveData() :

public void receiveData(String dataFromJS)
{
   //Do what you need with your data
}

让我们假设你有类似的东西在你的网页：

Let's say you have something like that in your web page :

<applet id ="appletID" name="myApplet" ... ></applet>

在JavaScript中，你只需要调用applet的public方法是这样的：

In your javascript you just have to call the applet public method like this :

var myApp = document.applets['myApplet'];
myApp.receiveData(taxElem.innerHTML + subtotalElem.innerHTML);

在previous例如将发送taxElem和subtotalElem内容的小程序。

The previous example will send the taxElem and subtotalElem content to the applet.

要从Applet的数据发送到您JS前人的精力使用的 JSObject 在你的applet

To send data from Applet to JS you sould use JSObject in your applet
