Hi Doug,
We do something similar, but with a check box and an input field, but the
process should be the same.
Javascript function that enables the input field based on the checkbox
accessed by form and index
function isBudgetRequired(form, index) {
checkBox = eval(form.elements["costElement[" + index + "].selected"]);
budgetInput = eval(form.elements["costElement[" + index +
"].budgetInputDisplay"]);
if (checkBox.checked) {
budgetInput.disabled = false;
}
else {
budgetInput.disabled = true;
}
}
JSP code snippet
<strutslogic:iterate id="data"
indexId="idx"
name="ouActivityDetailForm"
property="list">
<tr>
<td width="50" align="center">
<strutshtml:checkbox property="<%= "costElement[" + idx +
"].selected" %>"
onclick="<%=
"isBudgetRequired(this.form, " + idx + ")" %>" />
</td>
<td width="70" align="right">
<strutsbean:define id="checked"
name="ouActivityDetailForm"
property="<%= "costElement[" + idx +
"].selected" %>" />
<strutshtml:text name="ouActivityDetailForm"
property="<%= "costElement[" + idx +
"].budgetInputDisplay" %>"
size="6"
disabled="<%=
!((Boolean)checked).booleanValue() %>" />
</td>
</tr>
</strutslogic:iterate>

Hi again,
The form I am using extends the basic ActionForm class.

Ok, then you will probably be needing to use indexed properties.
I am trying to gather a bit of "working code" for you.
I should be finished shortly.
In the meantime, take a look at using indexed properties. Also, are you
using the DynaActionForm???
