applet中有：
public int getValue()
{
value = sb.getValue()*1000;
return value;
}
html中定义：<input type="text" name="R1" size="9" value="1">
怎样能做到当点击“提交”时（<input type="submit" value="提交" name="B1">
）将当前数值放到R1中（R1初始值1）？
public int getValue()
{
value = sb.getValue()*1000;
return value;

html中代码： <applet width="153" height="65" code="Progress1.class" codebase="." NAME="slider6" MAYSCRIPT>
</applet>
<FORM NAME="f" method="POST" action="YXT.jsp"><INPUT TYPE="button" VALUE="get slider value"ONCLICK="document.f.getval.value= document.slider6.getValue()">
<BR>
<INPUT TYPE="TEXT" NAME="getval" SIZE="10" ><input type="submit" value="提交" name="B1"></p>
</FORM>
现在不想用按钮来触发读applet的值，而是文本框随applet拖动改变而动，这样再提交。
怎么办？
<applet width="153" height="65" code="Progress1.class" codebase="." NAME="slider6" MAYSCRIPT>
</applet>
<FORM NAME="f" method="POST" action="YXT.jsp">
<INPUT TYPE="TEXT" NAME="getval" SIZE="10"><input type="submit" value="提交" ONCLICK="document.f.getval.value= document.slider6.getValue()" name="B1"></p>
</FORM>
用
<%@ page import="java.io.*" %>
<%@ page import="java.lang.Number"%>
<%@ page import="java.util.*"%>
<%@ page import="java.lang.Double"%>
<%! public String ex_chinese(String str){
if(str==null){
str ="" ;
}
else{
try {
str = new String(str.getBytes("iso-8859-1"),"gb2312") ;
}
catch (Exception ex) {
}
}
return str ;
}%> <html>

正在向服务器提交仿真参数........请等待

测试通过！明天到服务器上试试，有问题再请教大家
<input type="submit" value="提交" ONCLICK="document.f.getval.value= document.slider6.getValue()" name="B1"></p>脚本中还能这样访问applet中的方法，好样的。
