Struts Conditional Validations

Question

Hi All,
I am doing client side validation using struts frame work (struts 1.3).I wrote validations for a jsp
JSP
It’s having 2 radio buttons, 2 DIV.Based on the user selection I am showing DIV.
Logic:
If(radio== BusinesslegalEntityDIV)
Then show BusinesslegalEntityDIV
Else If(radio== IndividuallegalEntityDIV)
Then show IndividuallegalEntityDIV
<html:radio name="LookUpSearchForm" property="lookByIndOrBusiness"  value="BusinesslegalEntityDIV"    onclick="javascript:showDiv(this.value);">
</html:radio>
<html:radio name="LookUpSearchForm" property="lookByIndOrBusiness"  value="IndividuallegalEntityDIV"  onclick="javascript:showDiv(this.value);">
</html:radio> 
<div style="display: none"  id="IndividuallegalEntityDIV">
        <html:text property="UserlastName" size="33" maxlength="25"/>
</div>
<div style="display: none"  id=" BusinesslegalEntityDIV ">
        <html:text property="BusinessEntityName" size="33" maxlength="25"/>
</div>Validations.xml
<form      name="LookUpSearchForm">
<field property=" UserlastName " depends="validwhen">
<arg key="UserlastName"/>
      <var>
              <var-name>test</var-name>
              <var-value>((lookByIndOrBusiness=="IndividuallegalEntityDIV") and (*this* == null))</var-value>
         </var>
</field>
<field property="businessEntityName" depends="validwhen">  
             <arg key="businessEntityName"/>
                    <var>  
                     <var-name>test</var-name>  
                     <var-value>((lookByIndOrBusiness== "BusinesslegalEntityDIV") and (*this* == null))</var-value>
                     </var>                          
            </field>
</form>If I Selects Radio BusinesslegalEntityDIV then its asks for UserlastName,similarly if I select radio IndividuallegalEntityDIV then its asks for businessEntityName.Which I don’t want.

Put onKeyUp="Check(this)" in the Tabular Form Element attributes box for the COMM field.
Put the following script in the Region header
<script type="text/javascript">
function Check(pComm)
var comm=pComm.value;
var sal=pComm.parentNode.previousSibling.getElementsByTagName('input')[0].value;
if (Number(comm)>Number(sal)) {
  alert('Commission cannot be greater than salary!');
  pComm.focus();
</script>Enter a number like 3000 in the COMM field on the first row, you will get the alert box. Be sure to click OK on the Alert box and not hit Enter. :-)
But I agree 100% with Chris, these kind of data validations need to be enforced on the server as well as the client. If some other front-end is written on the same tables, you don't want to compromise data integrity if that front-end "forgets" to enforce this business rule.
Hope this helps.
