Ciao a tutti.
Ho implementato da struts l'uso del validator tramite javascript per validare una data in formato HH:mm
nel file validation.xml ho creato la seguente validazione
<formset>
<form name="nomeForm">
<field property="oraInizio"
depends="required,date">
<arg key="oraInizio"/>
<var>
<var-name>datePattern</var-name>
<var-value>HH:mm</var-value>
</var>
</field>
<field property="oraFine"
depends="required,date">
<arg key="oraFine"/>
<var>
<var-name>datePattern</var-name>
<var-value>HH:mm</var-value>
</var>
</field>
</form>
</formset>
poi all'interno della mia pagina jsp:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<html:javascript formName="nomeForm"/>
<html:form action="ee" onsubmit="return validatenomeForm(this)">
<table border="1" width="100%">
<tr>
<th class="right">
<bean:message key="oraInizio"/>
</th>
<td class="left">
<html:text name="nomebean" property="oraInizio" size="5" />
</td>
</tr>
<tr>
<th class="right">
<bean:message key="oraFine"/>
</th>
<td class="left">
<html:text name="nomebean" property="oraFine" size="5" />
</td>
</tr>
<tr>
<td class="right">
<html:submit>
<bean:message key="button.submit"/>
</html:submit>
</td>
<td class="right">
<html:reset>
<bean:message key="button.reset"/>
</html:reset>
</td>
</tr>
</table>
</html:form>
<logic:messagesPresent>
<UL>
<html:messages id="error">
<LI><bean:write name="error"/></LI>
</html:messages> [/list]
</logic:messagesPresent>
inserendo un valore del tipo 08:30 sul campo ora inizio, javascript risponde che oraInizio non e' un formato corretto...
Perche?
Riporto anche il javascript che struts crea in automatico:
function validateDate(form) {
var bValid = true;
var focusField = null;
var i = 0;
var fields = new Array();
var formName = form.getAttributeNode("name");
oDate = eval('new ' + formName.value + '_DateValidations()');
for (x in oDate) {
var field = form[oDate[x][0]];
var value = field.value;
var datePattern = oDate[x][2]("datePatternStrict");
// try loose pattern
if (datePattern == null)
datePattern = oDate[x][2]("datePattern");
if ((field.type == 'hidden' ||
field.type == 'text' ||
field.type == 'textarea') &&
(value.length > 0) && (datePattern.length > 0) &&
field.disabled == false) {
var MONTH = "MM";
var DAY = "dd";
var YEAR = "yyyy";
var orderMonth = datePattern.indexOf(MONTH);
var orderDay = datePattern.indexOf(DAY);
var orderYear = datePattern.indexOf(YEAR);
if ((orderDay < orderYear && orderDay > orderMonth)) {
var iDelim1 = orderMonth + MONTH.length;
var iDelim2 = orderDay + DAY.length;
var delim1 = datePattern.substring(iDelim1, iDelim1 + 1);
var delim2 = datePattern.substring(iDelim2, iDelim2 + 1);
if (iDelim1 == orderDay && iDelim2 == orderYear) {
dateRegexp = new RegExp("^(\\d{2})(\\d{2})(\\d{4})$");
} else if (iDelim1 == orderDay) {
dateRegexp = new RegExp("^(\\d{2})(\\d{2})[" + delim2 + "](\\d{4})$");

} else {

}
var matched = dateRegexp.exec(value);
if(matched != null) {
if (!isValidDate(matched[2], matched[1], matched[3])) {
if (i == 0) {
focusField = field;
}
fields[i++] = oDate[x][1];
bValid = false;
}
} else {
if (i == 0) {
focusField = field;
}
fields[i++] = oDate[x][1];
bValid = false;
}
} else if ((orderMonth < orderYear && orderMonth > orderDay)) {
var iDelim1 = orderDay + DAY.length;
var iDelim2 = orderMonth + MONTH.length;
var delim1 = datePattern.substring(iDelim1, iDelim1 + 1);
var delim2 = datePattern.substring(iDelim2, iDelim2 + 1);
if (iDelim1 == orderMonth && iDelim2 == orderYear) {

} else if (iDelim1 == orderMonth) {

}
var matched = dateRegexp.exec(value);

}
function isValidDate(day, month, year) {
if (month < 1 || month > 12) {
return false;
}

return false;
}
if ((month == 4 || month == 6 || month == 9 || month == 11) &&

return false;
}
if (month == 2) {
var leap = (year % 4 == 0 &&
(year % 100 != 0 || year % 400 == 0));

return false;
}
}
return true;
}
Premetto che disabilitando javascript, la validazione lato server funziona correttamente.
