struts2验证框架，验证密码和确认密码是否相同，怎么验证
我是说struts2验证框架

Answer 1

有两种，一个是字段验证，一个是验证器验证
我喜欢应字段验证
<validators>
<field name="password"
<field-validator type="requiredString">
<param name="trim">true</param>
<message>不能为空</message>
</field-validator>
</field>
<field name="againpassword"
<field-validator type="fieldexpression">
<param name="expression"><![CDATA[againpassword==password]]></param>
<message>My credit limit should be MORE than my girlfriend</message>
</field-validator>
</field>

</vaidators>

这个是字段验证~

Answer 2

<script type="text/javascript">
<!--
function checkPassword(){
if(form1.newpass1.value!=form1.newpass2.value){
alert("两次密码输入不一致，请重新输入");
form1.newpass1.value="";
form1.newpass2.value="";
form1.newpass1.focus();
}else if(form1.newpass1.value == "") {
alert("密码不能为空");
form1.newpass1.value="";
form1.newpass2.value="";
form1.newpass1.focus();

}else form1.submit();
}
-->
</script>

<form action="" name="form1">
密码:<input type="password" name="newpass1"/>
确认密码:<input type="password" name="newpass2"/>
</form>
