How to filter data in JSP?

Question

Hi All,
I have to filter data before I can display a drop down in my JSP. The scenario is as follows
There are 2 buttons on screen A. Button B1 and button B2.
Clicking on any one of these will result in screen B being displayed.
But if B1 is clicked then option 'ABC' should not be displayed in my dropdown.
If B2 is pressed only ABC should be displayed in the same field. (this is not a drop down now).
The current code snippet to fetch the data from the DB and display in the dropdown is:
<tr>
<td align="right" class="label" scope="row">
<span class="red"><html:label name="*" fieldId="<sectionId>.reasonId"/></span> 
<html:label name="Reason:" fieldId= "<sectionId>.reasonId" />
</td>
<td colspan="2">
<html:select name= "VoidPaymentForm" property = "paymentHeader.reasonId"
fieldId = "<sectionId>.paymentHeader.reasonId" onchange="voidPaymentNSF();">
<refdata:load id="listReason" source="<%=RefDataConstants.REASON %>"
name = "VoidPaymentForm" property="paymentHeader.reasonId"
parentSource="<%=RefDataConstants.ACCOUNTING_TRANSACTION_TYPE%>"
parentCodeValue="reasonCodeRef" />
<html:option value=""> </html:option>
<refdata:options collection="listReason" labelProperty="label" property="value"/>
</html:select>
</td>
</tr>
Appreciate your help.
Thanks and Regards,
Ashley

Answer 1

first, your screen A needs to send the information which button has been clicked. Then screen B needs to retrieve this value, if I'm not mistaken (it has been a view years ago, that I've written JSPs), you can put the html code within an if-statement. So, only when the condition is true, it will use the html code within.
