If you havn't done so, I'd suggest you view souce and see if you have the correct
javascript code rendered in you jsp. If you set staticJavascript="true" in your
<html:javascript ... tag, then the javascript should be rendered inside your jsp. You
can even put in some alert box in your validator-rules.xml file to see if the required
method actually gets called. BTW, do you have javascript validation working for other
type of form fields?

Subject: urgent:multibox client side validation
Dear Friends,
I have implemented multibox, everything is working fine.
But I would like to validate the checkboxes, my purpose is atleast one
checkbox will be selected from the user while submitting, if not message
will be pop up.
I am implementing javascript(client side) validation,
My validation.xml contains following code
<field property="selectedMagazines" depends="required">
<arg0 key="interestsForm.selectedMagazines"/>
</field>
I have tried the code, which is posted by "Yuan" as follows in
validator-rule.xml, but it didn't worked out.
function validateRequired(form) {
var isValid = true;
var focusField = null;
var i = 0;
var fields = new Array();
oRequired = new required();
for (x in oRequired) {
var field = form[oRequired[x][0]];
if (field.type == 'text' ||
field.type == 'textarea' ||
field.type == 'file' ||
field.type == 'select-one' ||
field.type == 'radio' || // -- true for single
radio button, Saul Q Yuan ([EMAIL PROTECTED]) 10/28/03
field.type == 'checkbox' || // -- true for
single checkbox, Saul Q Yuan ([EMAIL PROTECTED]) 10/28/03
field.type == 'password') {
var value = '';
// get field's value
if (field.type == "select-one") {
var si = field.selectedIndex;
if (si >= 0) {
value = field.options[si].value;
}
// -- get value for
checked single radio button or checkbox, Saul Q Yuan
([EMAIL PROTECTED]) 10/28/03
} else if (field.type ==
"radio" || field.type == "checkbox") {
if
(field.checked) {
value =
field.value;
}
} else {
value = field.value;
}
if (trim(value).length == 0) {
if (i == 0) {
focusField = field;
}
fields[i++] = oRequired[x][1];
isValid = false;
}
} else if (field.type == "select-multiple") {
var numOptions = field.options.length;
lastSelected=-1;
for(loop=numOptions-1;loop>=0;loop--) {
if(field.options[loop].selected) {
lastSelected = loop;
value = field.options[loop].value;
break;
}
}
if(lastSelected < 0 || trim(value).length == 0)
{
if(i == 0) {
focusField = field;
}
fields[i++] = oRequired[x][1];
isValid=false;
}
} else if ((field.length > 0) && (field[0].type ==
'radio' || field[0].type == 'checkbox')) {
isChecked=-1;
for (loop=0;loop < field.length;loop++) {
if (field[loop].checked) {
isChecked=loop;
break; // only one needs to be checked
}
}
if (isChecked < 0) {
if (i == 0) {
focusField = field[0];
}
fields[i++] = oRequired[x][1];
isValid=false;
}
}
}
if (fields.length > 0) {
focusField.focus();
alert(fields.join('\n'));
}
return isValid;
}
