关于使用jQuery.validate验证表单中两次密码是否一致的有关问题

关于使用jQuery.validate验证表单中两次密码是否一致的问题
今天用了下validate   其他没问题  就是验证两次密码是否一致时总是无法通过是为什么 ？
语法是按照网上的文档写的。
$("#aspnetForm").validate({
                rules: {
                    txtName: {
                        required: true
                    },
                    txtTrueName: {
                        required: true
                    },
                    txtPass: {
                        required: true,
                        minlength: 3
                    },
                    txtTwoPass: {
                        required: true,
                        minlength: 3,
                        equalTo: "#txtPass"
                    },
                    txtEmail: {
                        required: true,
                        email: true
                    },
                    txtAddress: {
                        required: true
                    },
                    txtPhone: {
                        required: true
                    }
                },
                messages: {
                    txtName: {
                        required: "*请输入用户名"
                    },
                    txtTrueName: {
                        required: "*请输入姓名"
                    },
                    txtPass: {
                        required: "*请输入密码",
                        minlength: "*密码不能小于3个字符"
                    },
                    txtTwoPass: {
                        required: "*请输入确认密码",
                        minlength: "*密码不能小于3个字符",
                        equalTo: "*请再次输入相同的值"
                    },
                    txtEmail: {
                        required: "*请输入邮箱",
                        email: "*请输入正确的邮箱格式"
                    },
                    txtAddress: {
                        required: "*请输入地址"
                    },
                    txtPhone: {
                        required: "*请输入手机号码"
                    }
                }
            });

为什么明明我输入的两次密码是一致的还一直提示我呢？
试过不同的浏览器和不同版本的validate都是如此   。。
------解决思路----------------------
会不会是你的表单密码项的name和validate里的不一致
