如何从Java Applet调用JS函数？

Question

Well, this is my trouble: 好吧，这是我的麻烦：

I have an applet that controlls a magnetic stripe reader and I need to call a JS function when the MSR reads a card to catch the data and submit in a form. 我有一个控制磁条读取器的小程序，当MSR读取卡以捕获数据并以表格形式提交时，我需要调用JS函数。 The problem is the applet cannot call JS functions when it is called from a remote PC o server, but locally all the code works fine. 问题是，当从远程PC o服务器上调用applet时，applet无法调用JS函数，但是在本地所有代码都可以正常工作。 I supposed that is a issue of privileges on the browser. 我以为那是浏览器特权的问题。 This is my HTML code: 这是我的HTML代码：

<html>
<head>
    <title>Applet Prueba</title>
    <script src="jquery-1.7.1.min.js" type="text/javascript"></script>
    <script type="text/javascript">
    $(document).ready(function()
    {
        $("#AppletPrueba")[0].apOpenPrinter();
        $("#AppletPrueba")[0].apActivaMSR();
    });

    function print()
    {
        $("#AppletPrueba")[0].apPrintCreditInfo();
    }

    function setTxtBox(texto)
    {
        $("#txtBox").val(texto);
    }
    </script>
</head>
<body>
    <object id      = "AppletPrueba"
            classid = "clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
            width   = "1"
            height  = "1">
        <param name="code" value="applet.AppletJPos.class"/>
        <param name="archive" value="SAppletJPos.jar,Sjpos11021.jar,Sjpos191.jar,SNCRJavaPOS39.jar,SNCRJavaPOSClasses.jar,Sxerces.jar"/>
        <param name="scriptable" value="true"/>
        <param name="mayscript" value="true"/>
        <param name="param0" value="1"/>
        <param name="param1" value="Tienda"/>
        <param name="param2" value="XXX"/>
        <param name="param3" value="RUBEN C. FLORES GARNETT"/>
        <param name="param4" value="09 de Marzo de 2012"/>
        <param name="param5" value="0.00"/>
        <param name="param6" value="0.00"/>
        <param name="param7" value="0.00"/>
        <param name="param8" value="0.00"/>
        <param name="param9" value="0.00"/>
        <param name="param10" value="0.00"/>
        <param name="param11" value="0"/>
        <param name="param12" value="0.00"/>
        <param name="param13" value="0.00"/>
        <param name="param14" value="0.00"/>
        <param name="param15" value="0.00"/>
        <param name="param16" value="0.00"/>
        <param name="param17" value="0.00"/>
        <param name="param18" value="0.00"/>
        <param name="param19" value="0.00"/>
        <param name="param20" value="0.00"/>
        <param name="param21" value="0.00"/>
        <param name="param22" value="0.00"/>
        <param name="param23" value="0.00"/>
        <param name="param24" value="1"/>
    </object>
    <input type="button" value="Imprime Ticket" onclick="print()" />
    <br/>
    <input type="text" value="" id="txtBox" />
</body>

And that is the way the applet call the JS function: 这就是applet调用JS函数的方式：

AppletContext appletCtxt = getAppletContext();

... ...

appletCtxt.showDocument(new URL("javascript: setTxtBox('" + editedCardId[0] + "')"));

I really hope somebody can help me. 我真的希望有人能帮助我。

The Oracle tutorial on the matter would probably be useful. 有关此问题的Oracle教程可能会很有用。
