Re: clarification please

With JavaScript you could count the <td>/<tr>-elements (works only in IE!),
if in the HTML-source you set the name of the last <td>/<tr>-element to name
(<td name="name">):

function countTD() {

    numberOfTDElements = document.all.name.sourceIndex;
    alert("Number of <td>-elements: " + numberOfTDElements);
}

The second one is a bit more tricky.
You must create a JavaScript-function that reads the content of the
<td>-elements, creates depending on these values an URL to your servlet
which you want the <td>-values to be passed to.
For example:
function getTDContent() {
    allTDs = countTD(); // used the other script to get the number of <td>'s
used
    var url = "http://server/servlet/ServletName";
    for (i = 0; i < allTDs; i++)

        if (i==0)
            url +=  "?parameter" + i + "=" +
document.all.tags("td")[i].innerText;
        else
            url += "&parameter" + i + "=" +
document.all.tags("td")[i].innerText;
    }
    return url;
}

function openServlet() {
    window.document.location.href = getTDContent();
}

Note: Both Scripts will only work with Internet Explorer because Netscape
doesn't know the 'all' element,if you want to use them in Netscape you must
replace all those 'all.tags("td")[index]' with 'all.elementName'!
