action中用对象接收form中提交数据怎样用jquery-validate验证？
$().ready(function() {$("#signupForm").validate({ rules: { user.u=firstname: "required", email: { required: true, email: true }, user.password: { required: true, minlength: 5 }, user.confirm_password: { required: true, minlength: 5, equalTo: "#password" }}, messages: { user.firstname: "请输入姓名", email: { required: "请输入Email地址", email: "请输入正确的email地址" }, user.password: { required: "请输入密码", minlength: jQuery.format("密码不能小于{0}个字符") }, user.confirm_password: { required: "请输入确认密码", minlength: "确认密码不能小于5个字符", equalTo: "两次输入密码不一致不一致" }} });});<form id="signupForm" method="get" action=""> <p> <label for="firstname">Firstname</label> <input id="firstname" name="user.firstname" /> </p><p><label for="email">E-Mail</label><input id="email" name="user.email" /></p><p><label for="password">Password</label><input id="password" name="user.password" type="password" /></p><p><label for="confirm_password">确认密码</label><input id="confirm_password" name="user.confirm_password" type="password" /></p> <p> <input class="submit" type="submit" value="Submit"/> </p></form>
