determining which submit button is pressed and setting a hidden value 1

[excession]

I have a for which contains a table of items. The last column has a button in each row called "Place Bid"

When I process the form how can I tell which of the "Place Bid" buttons was actually clicked?

I've been trying to use javascript to set a hidden value, but I've a novice with JS.

Any suggestions?

and example of my for:


<form name="bidding" method="post" action="PlaceBid.jsp">
<table width="200" border="1">
<tr>
<td>Item 1</td> <td> etc etc </td>

<td> <input type="submit" name="Submit" value="Place Bid"> </td>
</tr>
</table>
<input type="hidden" name="whichbutton" value="?">
<input type="hidden" name="by" value="<%=request.getParameter("by")%>">
</form>

Use an onclick handler on each of your submit buttons. This onclick event will trigger before the page is submitted, so you can set any hidden variables you need to at that time. Try something like this for your multiple submit buttons:

<form name="bidding" method="post" action="PlaceBid.jsp">
...
...
<input type="submit" name="Submit" value="Place Bid" onclick='document.forms["bidding"].elements["whichbutton"].value=1'>
...
<input type="submit" name="Submit" value="Place Bid" onclick='document.forms["bidding"].elements["whichbutton"].value=1'>
...
<input type="submit" name="Submit" value="Place Bid" onclick='document.forms["bidding"].elements["whichbutton"].value=1'>
...
<input type="hidden" name="whichbutton" value="?">
...
</form>

gah.... I made a typo in the post. The values were supposed to increment:

.value=1
.value=2
.value=3

But I'm sure you got the idea
