Hi!
Im using Struts 1.1 RC1 and I want to validate user input. I have a password field
that should have at least 6 characters. Therefore, I use the following validator-rule
in validator-rules.xml:
<form-validation>
<global>
<validator name="minlength"
classname="org.apache.struts.validator.FieldChecks"
method="validateMinLength"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionErrors,
javax.servlet.http.HttpServletRequest"
depends="required"
msg="errors.minlength">
<javascript><![CDATA[
function validateMinLength(form) {
var bValid = true;
var focusField = null;
var i = 0;
var fields = new Array();
oMinLength = new minlength();
for (x in oMinLength) {
if (form[oMinLength[x][0]].type == 'text' ||
form[oMinLength[x][0]].type == 'textarea') {
var iMin = parseInt(oMinLength[x][2]("minlength"));
if (form[oMinLength[x][0]].value.length < iMin) {
if (i == 0) {
focusField = form[oMinLength[x][0]];
}
fields[i++] = oMinLength[x][1];
bValid = false;
}
}
}
if (fields.length > 0) {
focusField.focus();
alert(fields.join('\n'));
}
return bValid;
}]]>
</javascript>
</validator>
<!-- ... -->
</global>
</form-validation>
The validator is used in validation.xml like this:
<form-validation>
<formset>
<form name="logonForm">
<!-- ... -->
<field property="password" depends="required,minlength">
<arg0 key="prompt.password"/>
<arg1 name="minlength" key="${var:minlength}" resource="false"/>
<var>
<var-name>minlength</var-name>
<var-value>6</var-value>
</var>
</field>
</form>
</formset>
</form-validation>
My logon.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<html:html locale="true">
<body>
<html:form action="/logon" focus="username" onsubmit="return
validateLogonForm(this);">
<table border="0" width="100%">
<!-- ... -->
<tr>
<th align="right" width="50%">
<bean:message key="prompt.password"/>:
</th>
<td align="left" width="50%">
<html:password property="password" size="16" maxlength="18"
redisplay="false"/>
</td>
</tr>
</table>
<!-- Submit and cancel button -->
</html:form>
<html:javascript formName="logonForm" dynamicJavascript="true"
staticJavascript="true" />
</body>
</html:html>
Last but not least, the entry in the struts-config.xml:
<plug-in className="org.apache.struts.validator.ValidatorPlugIn" >
<set-property property="pathnames"
value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>
</plug-in>
My problem is that there is only a server-side validation for the minlength-property.
If nothing is entered in the password-field, Javascript-validation (required) works
fine (i.e the validation is done on client-side). What am I doing wrong?
Thanks for help!
Stefan
