Question
Loop through HTML table
I would like to be able to loop through the following table. This is actually in a JSP that I will be using the looped data to call a java function.
<TABLE >
<TR>
<TH><input type="checkbox" name="masterChk"/></TH>
<TH>Symbol</TH>
<TH>Name</TH>
<TH>Price</TH>
</TR>
Thanks
<%
java.util.Iterator folio = portfolio.getPortfolio();
Stock stock = null;
int recordCnt = 0;
while (folio.hasNext())
{
recordCnt++;
stock = (Stock)folio.next();
String stockSymbol = stock.getSymbol();
String stockName = stock.getName();
Float stockPrice = stock.getPrice();
%>
<TR>
<TD><input type="checkbox" name="chk<%=recordCnt%>" value="<%=stockSymbol%>"/>
<TD><%=stockName%></TD>
<TD><%=stockSymbol%></TD>
<TD><input type=text name="stockPrice<%=recordC
</TR>
<%
}
%>
</TABLE>

You need to do a bunch of things. This tutorial should explain things clearly - http://www.devsphere.com/m
<input type="hidden" id="hidChkBoxVal" value=""/>
function getSelValues(frm){
var el = frm.elements;
for(i=0;i<el.length;i++) {
if(el[i].type == "checkbox" && el[i].checked){
document.getElementById('h
}
}
}
Now in ur servlet you can get the selected checkbox values as an String array.
String[] checkedValues = null;
if(request.getParameter("h
checkedValues = request.getParameter("hidC
}
Hope this is what you are looking for.

Well I was able to get the following to loop through each row and get the values of the columns. So now I have to put into the JSP. I did the following through HTML. I will put it into a JSP and see what happens.
function loopThroughTable() {
rows=document.getElementBy
for (var i=0; i<rows.length; i++)
{
cols=document.getElementBy
for (var i=0; i<cols.length; i++)
{
cols[i].style.backgroundCo
alert(cols[i].innerHTML);
}
}
}
