价值传递的Java小程序 [英] value passing in java applet

问题描述

我传递价值，Java小程序，但值快到那里空

我的JavaScript小应用程序的部署：

 ＆LT;脚本SRC =JavaScript的/ deployJava.js＆GT;＆LT; / SCRIPT＆GT;
＆LT;脚本＆GT;
    VAR属性= {ID：'dynamictreeapplet'，code：'jstojava.com.vaannila.utility.dynamicTreeApplet.class'，宽：1000，高：1000};
    VAR参数= {jnlp_href：./ appletjars / a.jnlp'};
    deployJava.runApplet（属性，参数，'1.6'）;
＆LT; / SCRIPT＆GT;
 

我的JNLP

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
＆LT; JNLP规范=1.0+codeBase的=HTTP：//本地主机：8080 / docRuleToolProtocol / appletjars /HREF =a.jnlp＆GT;    ＆LT;信息＆gt;
        ＆LT;标题＆GT; dynamictree＆LT; /标题＆GT;
        ＆LT;卖主GT;＆Ashutosh说LT; /卖主GT;
    ＆LT; /信息＆gt;    ＆LT;资源＆GT;
        ＆LT; J2SE版本=1.5 +HREF =htt​​p://java.sun.com/products/autodl/j2se/＆GT;
        ＆LT;罐子HREF =dynamictree.jar主要=真/＆GT;
        ＆LT;罐子HREF =prefuse.jar主要=真/＆GT;
    ＆LT; /资源＆GT;
 

JavaScript来传递值：

 函数showSelected（值）{
警报（+价值，从给定的值）;
VAR diseasename =价值;
警报（diseasename）;
dynamictreeapplet.dieasenameen code = diseasename;
}    ＆LT;小程序，说明NAME =dynamictree主级=com.vaannila.utility.dynamicTreeAppletWIDTH =500HEIGHT =500＆GT;
    ＆LT; / applet的递减＆GT;
＆LT; / JNLP＆GT;
 

解决方案

修改

  dynamictreeapplet.dieasenameen code = diseasename;
 

到

  document.dynamictreeapplet.dieasenameen code = diseasename;
 

和可能dieasenameen code到diseasenameen code。

i am passing value in java applet but value is coming there as null

my javascript for applet deployment :

<script src="javascript/deployJava.js"></script>
<script>
    var attributes = { id:'dynamictreeapplet', code:'jstojava.com.vaannila.utility.dynamicTreeApplet.class',width:1000,height:1000} ;
    var parameters = {jnlp_href:'./appletjars/a.jnlp'} ;
    deployJava.runApplet(attributes, parameters, '1.6');
</script>

My jnlp

<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="http://localhost:8080/docRuleToolProtocol/appletjars/" href="a.jnlp">

    <information>
        <title>dynamictree</title>
        <vendor>Ashutosh</vendor>
    </information>

    <resources>
        <j2se version="1.5+" href="http://java.sun.com/products/autodl/j2se" />
        <jar href="dynamictree.jar" main="true" />
        <jar href="prefuse.jar" main="true" />
    </resources>

javascript to pass value :

function showSelected(value){
alert("the value given from"+value);
var diseasename=value;
alert(diseasename);
dynamictreeapplet.dieasenameencode=diseasename; 
}

    <applet-desc name="dynamictree" main-class="com.vaannila.utility.dynamicTreeApplet" width="500" height="500">
    </applet-desc>
</jnlp>

解决方案

Change

dynamictreeapplet.dieasenameencode=diseasename;

to

document.dynamictreeapplet.dieasenameencode=diseasename;

and probably dieasenameencode to diseasenameencode .
