Extracting data from a form

[AnthonyGeorge]

I have a difficult problem with no idea how to solve it. I think javascript is the best approach, but have very limited experience of javascript

The problem is as follows at the moment I have the following code

while(rs.next())
{
%> <form name="setlimits" method=POST action="controlservlet">
<tr>
<td>
<input type="text" name="new_limit" size=10 value="0" >
<input type="hidden" name="index" value="<%= rs.getString("index") %>">
<td>
<tr>
<tr>
<input type="submit" value="Amend Limit">
</form>
<tr>
<%
}

When I press submit the control servlet is called and two parameters passed to it new_limit and a corresponding index.
This allows me to update a table row with the new_limit in the database where index = index.

What I have now been asked to do is supply a submit all button, when this button is pressed I should pass to the control servlet all the new limits with all the corresponding indexs.

As I see it I will prob have to write a javascript function that will pick up all the new limts and indexs and store them in a javascript document

Thanks for any help Tony

Hi Vbkris

My fault I did not explain the problem properly

I have the this form within a loop

<form name="limits" method=POST action="global">
<input type="text" name="new_limit" size=10>
<input type="hidden" name="borg_num" value="<%= rs.getString("borg_num") %>">
<input type="submit" value="Amend Limit">

when run it will look like this if I have 4 limits to set

limits
[] (amend limit)
[] (amend limit)
[] (amend limit)
[] (amend limit)

I enter data into one of the boxes say 10 and press the button (ammend limit) then the data entered 10 plus
the hidden identifier for that limit borg_num will be fired of to the control servlet.

I have been asked to add another button (ammend all)

limits
[] (amend limit)
[] (amend limit)
[] (amend limit)
[] (amend limit)

(amend all)

what this button will do is if I enter data in all four boxes on pressing submit I will need to get all 4 limits with all four matching borg_num identifiers and pass to the controlservlet.


I have written the amend all button

<input type="button" value="Amend All" onclick="submitAll()" />
<form name="allForm" method=POST action="global">
<input type="hidden" name="cmd" value="temp_limits">
</form>

and have started the javascript function
<script>
function submitAll()
{
document.getElementById("allForm").submit();
}
</script>

I have no idea how to pick up new_limit and borg_num from the form and store them in a document.

Thanks for any help.
