下载jvm时如何获取文件大小？ [英] How can I get file size while downloading jvm ?

问题描述

我正在使用这个javascript： http://www.java.com/js/deployJava.js



我的javascript代码：

Hi, I am using this javascript :http://www.java.com/js/deployJava.js

My javascript code:

function Test()
{
	var attributes = {codebase:'http://java.sun.com/products/plugin/1.5.0/demos/jfc/Java2D',
                      code:'java2d.Java2DemoApplet.class',
                      archive:'Java2Demo.jar',
                      width:710, height:540} ;
    var parameters = {fontSize:16} ;
    var version = jsver ;
    deployJava.setInstallerType('kernel');
   // include any required packages as shown below
    deployJava.setAdditionalPackages('javax.swing, javax.xml');
    deployJava.runApplet(attributes, parameters, version);
}

下载jvm这个工作得很好。现在我想在我的html代码中添加一个进度条：

This working good to download jvm. Now I want to add a progress bar in my html code:

<progress value="0" max="100">0 %</progress>

现在，我想在下载JVM时展示这个进程。请帮帮我。

Now, I want to show this progess while I am downloading the JVM. Please help me.

推荐答案

它是否暴露任何事件？如果不是，那么好的选择就是显示一个非确定性（圆形等）进度条。

Does it expose any events? If not the good bet would be to show a non-deterministic (round etc) progress bar.
