<%@ta glib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> 

<pre>Bin</pre>
<pre>UPC Code</pre>
<pre>Total Tickets</pre>
<pre>Balance</pre>
<pre>Value</pre>
<pre>Tickets Sold</pre>
<pre>Total</pre>
<pre>End of Life</pre>

<c:forEach items="${scratchlistlotto }" var="sl">
   <input name="scratchid" type="hidden"    id="scratchid"  value="${sl.scratchid }" />             
   <input name="binid" type="text"  class="table_color1" id="binid"   value="${sl.bin }" /> 
   <input name="upccode" type="text"   id="upccode"   value="${sl.upccode }" /></td>

   <input name="totalticketss" type="text"   id="totalticketss"   value="${sl.totaltickets }"/>
   <input name="openingbalance" type="text" id="openingbalance" value="${sl.closingbalance }" />
   <input name="closingbalnce" type="text" id="closingbalnce" onchange="javascript:Total(this.value)"    />    

   <input name="value" type="text"   id="value"   size="6" value="${sl.values }" /> 
   <input name="ticketssold" type="text"   id="ticketssold"   /> 
   <input name="total" type="text"   id="total"   />
   <input type="text" name="hidden" value="${sl.i }"/>
   <input name="endoflife" type="checkbox" class="text_border" id="endoflife"    /></td>

</c:forEach>

function Total(v) { 
    var closingbalnce = parse Float(v);         
    var openingbalance = document.getElementById["openingbalance"].value;        
    var ob = document.getElementById["closingbalnce"].value;

    alert("hiiii "+ob);        
    alert("closingbalnce "+openingbalance); 

    var totalscratchtotal = parseFloat(document.name.totalscratchtotal.value);        
    var ts = closingbalnce-openingbalance;         
    document.name.ticketssold.value = ts;         
    var value = parseFloat(document.name.value.value);        
    document.name.total.value = ts  *value;          
    document.name.totalscratchtotal.value = totalscratchtotal + (ts * value);
}

我通过使用jstl标记在jsp页面中显示列表值，我的数组列表为（scratchlistlotto）当我将我的期末余额放在>文本框中时，我想将期初余额发送到java脚本方法中，请帮助我

function Total(v) 
      {   
//var closingbalnce=parseFloat(v);
var  closingbalnce=parseFloat(v);   
var hidden=parseFloat(document.name.hidden.value);    
var op="openingbalance".concat(hidden);  
var ts="ticketssold".concat(hidden); 
var v="value".concat(hidden);  
var openingbalance=parseFloat(document.getElementById(op).value);
var ticketssold=parseFloat(document.getElementById(ts).value); 
var value=parseFloat(document.getElementById(v).value); 
var totalsoldtickets=closingbalnce-openingbalance; 
var totalsoldtickets=(closingbalnce-openingbalance)*value;  
document.getElementById(ts).value=totalsoldtickets;
//document.name.ticketssold.value=total; 
alert("hiiii "+total);
