Question

I have a form which displays multiple rows from database with 4 columns. From these record I need to write a new value in 4th column and update database record. But whenever I try, only First Row value can be updated/read. But not the other rows!! This can be due to the same “name=redirection” as it is given to each from “for loop”. So, how can I get the values from other rows too??

for (int i=0; i<domains.size(); i++) {
domainprops = (String[]) domains.get(i);   
%>

<table cellspacing="0" cellpadding="10" border="0" class="tableview" width="100%">
<td width="150"><input type="text"  id="domains" name="domains" value="<%=domainprops[0]%>"></td>
<td width="160"><input type="text"  name="defaulturl" value="<%=domainprops[1]%>" size="30"></td>
<td width="160"><input type="text"  name="redirecturl" value="<%=domainprops[2]%>" size="30"></td>

<td width="160"> <input type="text" id="redirection" name="redirection"></td>

<td align="right"><a href="javascript:win2('recordUpdate.jsp?domains=<%=domainprops[0]%>
')">[Update]</a></td>

    </tr>
 </table>

<% } %>

Javascript Code :

function win2(urlPath) {
    var winl = (screen.width-200)/2;
    var wint = (screen.height-100)/2;
    var settings = 'height=100,width=200,directories=no,resizable=no,status=no,scrollbars=no,menubar=no,location=no,top=' + wint + ',left=' + winl;

    var changeurls=document.getElementById("redirection").value;
    urlPath+='&rdirect='+changeurls
    editWin.focus();
}

EDIT: Please read the answer referring to having multiple elements with the same ID. You should not be using multiple of the same ID.

You could use Javascript to iterate over redirection form elements.

function loopThroughRedirection(form) {
    var result = "";

    for (var i = 0; i < form.elements.length; i++) {
        if (form.elements[i].name == 'redirection') {
            // Do something to retrieve the value of redirection
            result += form.elements[i].value
        }
    }

    return result;
}
