基于表单中的无线电值的条件jquery验证

Question

我正在使用验证插件.当无线电值不是"REGULAR"时,我想验证同一形式的某些字段,

<form id="registerform">
<input type="radio" name="role" value="REGULAR" checked="checked" id="role">Regular<br />
<input type="radio" name="role" value="AGENT" id="role">Agent<br />
<input type="radio" name="role" value="ORGANIZATION" id="role">Organization<br />

<input type="text" name="phone"  id="phone"><br/>
<input type="text" name="password" id="password"><br/>

<input type="text" name="work_area" id="work_area" value=""><br/>
<input type="text" name="work_phone" id="work_phone" value=""><br/>

<input type="text" name="org_name" id="org_name"><br/>
<input type="text" name="org_phone" id="org_phone"><br/>
</form>

当role =="REGULAR"时,验证手机,密码
当role =="AGENT"时,验证手机,密码,work_area,work_phone
当role =="ORGANIZATION"时,验证手机,密码,org_name,org_phone
如何优雅地实现这一目标？
我不想把它分成不同的形式!

我的假代码:

$(document).ready(function() {
var rule_options = 
{
    "phone": "required"
    ,"password": "required"
};

var role = $("#registerform").find("input[name=role]:checked").val();
if(role ==  "AGENT") {
    $.extend(true, rule_options, 
        {
            "work_area": "required"
            ,"work_phone": "required"
        }
    );
}

if(role ==  "ORGANIZATION") {
    $.extend(true, rule_options, 
        {
            "org_area": "required"
            ,"org_phone": "required"
        }
    );
}
jform.validate({
            errorClass : "err_label",
            rules: rule_options,
            ignore: "",

上面的代码将无法工作,因为它只在document.ready之后运行一次.
我必须遗漏一些东西,一些语法......〜想法？

jquery验证规则
我从上面的链接得到了我真正需要的东西.什么真的需要这里要解决的是如何让jQuery的验证插件的行为动态地根据每个输入无线电值.我甚至不使用jQuery.change()方法.

function getRole() {
    return $("#registerform").find("input[name=role]:checked").val();
}

$(document).ready(function() {
    var jform = $("#registerform");
    jform.validate({
            errorClass : "err_label",
            rules: 
                "phone": "required"
                ,"password": "required"
                ,"work_area": {
                    required: function(element) {
                        return (getRole() == 'AGENT');
                    }
                }
                ,"work_phone": {
                    required: function(element) {
                        return (getRole() == 'AGENT');
                    }
                }
                ,"org_name": {
                    required: function(element) {
                        return (getRole() == 'ORGANIZATION');
                    }
                }
                ,"org_phone": {
                    required: function(element) {
                        return (getRole() == 'ORGANIZATION');
                    }
                }

如果存在其他想法,请告诉我.
