最近在研究tapestry，对其它的客户端验证产生疑惑，代码如下：
html:
<html>
<head>
</head>
<body jwcid="@Body">
<table width="400" border="1">
<form jwcid="loginForm">
<tr>
<td colspan="2" width="100%" align="center">
<span jwcid="@Insert" value="ognl:errorMsg"/>
</td>
</tr>
<tr>
<td colspan="2" width="100%" align="center">LOGIN</td>
</tr>
<tr>
<td width="32%" align="right">Username:</td>
<td align="left"><input type="text" jwcid="username" size="20"/></td>
</tr>
<tr>
<td width="32%" align="right">Password:</td>
<td align="left"><input type="password" jwcid="password" size="20"/></td>
</tr>
<tr>
<td align="center"><input type="submit" value="Login"/></td>
<td> <input jwcid="startDate@DatePicker" value="ognl:startDate" displayName="Start Date"/></td>
</tr>
<tr>
<td colspan="2" align="center"><a href="#" jwcid="registe">Registe</a></td>
<td colspan="2" align="center"><a href="#" jwcid="showAjax">ShowAjax</a></td>
</tr>
</form>
</table>
</body>
</html>
page:
<page-specification class="com.suzsoft.framework.example.web.pages.Home">
<property name="password"/>
<property name="errorMsg"/>
<property name="startDate"/>
<bean name="passwordValidator" class="com.suzsoft.framework.common.PasswordValidator"></bean>
<bean name="delegate" class="org.apache.tapestry.valid.ValidationDelegate"></bean>
<component id="loginForm" type="Form">
<binding name="listener" value="listener:loginSubmit"/>
<binding name="clientValidationEnabled" value="true" />
<binding name="delegate" value="beans.delegate"></binding>
</component>
<component id="username" type="TextField" >
<binding name="value" value="username" />
<binding name="validators" value="validators:required"/>
</component>
<component id="password" type="TextField">
<binding name="value" value="password"></binding>
<binding name="validators" value="beans.passwordValidator"/>
<binding name="hidden" value="true"/>
</component>
<component id="registe" type="PageLink">
<binding name="page" value="literal:Registe"></binding>
</component>
<component id="showAjax" type="PageLink">
<binding name="page" value="literal:ShowAjax"></binding>
</component>
</page-specification>
自定义校验对象java文件:
public class PasswordValidator implements Validator {
public void validate(IFormComponent field, ValidationMessages message, Object object) throws ValidatorException {
String password = (String) object;
if (!"123456".equals(password)) {
throw new ValidatorException("The password is invalid!");
}
}
public boolean getAcceptsNull() {
return true; //To change body of implemented methods use File | Settings | File Templates.
}
public boolean isRequired() {
return true; //To change body of implemented methods use File | Settings | File Templates.
}
public void renderContribution(IMarkupWriter writer, IRequestCycle cycle, FormComponentContributorContext context, IFormComponent field) {
writer.attribute("style","background-color:#999999");
}
}
为何我clientValidationEnabled＝＝true，只有username产生客户端验证，而password却没有在客户端产生javascript，进行客户端校验呢？请. 声明：ITeye文章版权属于作者，受法律保护。没有作者书面许可不得转载。

客户端验证只支持Tapestry内置的验证，自定义的验证是要通过java调用的，那是服务器端验证。
