Hi folks,
I have a problem which I have a kludgy solution for, and have to believe
there is a more elegant way of doing it... Here's the scenario.
The page displays a non-editable list of records in a database, with a
checkbox at the beginning of each row. The list is indeterminate length,
based on selection criteria entered by the user in the previous page. The
user selects n number of rows, using the check boxes. Those rows are to be
deleted from the database.
The trick is that the rows have a three column key. One is constant based
on the user, so I need to get 2 pieces of information from each row before
I can delete it.
My kludge is to have the value of the checkboxes be the indexId of the
logic:iterate. Each row has two hidden input fields, with the two required
key values. Something like this:
<logic:iterate id="item" name="listForm" property="txnList" type
="Transaction" indexId="counter">
<tr>
<td width="69" align="center">
<input type="checkbox" name="selectedTxns" value="<%=counter%>"/>
</td>
.... display data ...
<td width="88"><%=item.getTotal()%></td>
<!-- Hidden input fields so we can retrieve all the required data
about the selected transaction... -->
<td class="sidelink" width="1">
<input type="hidden" name="orderIds" value="<%=item.getOrderID
()%>"/>
</td>
<td class="sidelink" width="1">
<input type="hidden" name="deptAreas" value="<%=item.getDeptArea
()%>"/>
</td>
</tr>
</logic:iterate>
In the formData bean, I have three String [ ] attributes to accept the
values of the checkbox and the two hidden fields.
The problem is that since there is data in the hidden input fields for
every row, I get every value back in the array, instead of only the data
for the rows which are checked. What I have to do in the action is read
the values from the String [ ] for the checkbox , and use that value as the
index into the other two string arrays.
Like I said, its kludgy, but it works...
But, I have to believe there's a way to send back an array of beans, with
only the values of the fields for those rows which are checked, but I can't
find anything in books or searching the web which describes how to do this.
Does anyone have a cleaner way to do this type of thing?
Thanx!
c'ya
Mike
