Hi there, here is my implementation on the client side, it's validate
time against the pattern HH:mm, you can customize against HH:mm:ss with
ease:
<validator name="time"
classname="MyValidatorClass"
method="validateTime"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
org.apache.commons.validator.Validator,
javax.servlet.http.HttpServletRequest"
msg="errors.time"
jsFunctionName="TimeValidations">
<javascript>
<![CDATA[
function validateTime(form){
var isValid = true;
var focusField = null;
var i = 0;
var fields = new Array();
var formName = form.getAttributeNode("name");
oTime = eval('new ' + formName.value + '_TimeValidations()');
for (x in oTime) {
var field = form[oTime[x][0]];
var value = field.value;
if ((field.disabled == false) && (value.length > 0) &&
(field.type == 'text' || field.type == 'textarea')) {
var timeParts = field.value.split(":");
var hour = timeParts[0];
var minute = timeParts[1];
try{
if(hour.length != 2 || minute.length != 2){
fields[i++] = oTime[x][1];
focusField = field;
isValid = false;
} else {
if(isNaN(hour)||isNaN(minute)){
fields[i++] = oTime[x][1];
focusField = field;
isValid = false;
} else {
hour = parseInt(hour);
minute = parseInt(minute);
if(hour>=24 || hour < 0 || minute >=60 || minute <0){
fields[i++] = oTime[x][1];
focusField = field;
isValid = false;
}
}
}
} catch(e){
fields[i++] = oTime[x][1];
focusField = field;
isValid = false;
}
}
}
if (fields.length > 0) {
focusField.focus();
alert(fields.join('\n'));
}
return isValid;
}
]]>
</javascript>
</validator>
Here is the Server side: this method is in the MyValidatorClass
public static boolean validateTime(Object bean, ValidatorAction va,
Field field,
ActionMessages errors, Validator validator,
HttpServletRequest request) {
boolean result = true;
try {
String value = ValidatorUtils.getValueAsString(bean,
field.getProperty());
if (!GenericValidator.isBlankOrNull(value)) {
result = Pattern.matches("[0-2][\\d]:[0-5][\\d]", value);
if (result == true) {
String hour = value.substring(0, 2);
String minute = value.substring(3);
int hourInt = Integer.parseInt(hour);
int minuteInt = Integer.parseInt(minute);
if (hourInt < 0 || hourInt >= 24 || minuteInt < 0 ||
minuteInt >= 60) {
result = false;
}
}
}
} catch (NumberFormatException e) {
result = false;
e.printStackTrace();
}
if (result == false) {
errors.add(field.getKey(),
Resources.getActionMessage(validator, request, va, field));
}
return result;
}
Maybe it's not the best you can found on the web! Use it at your own risk.
