使用Jquery Validator的IE11中密码验证失败

我在IE11和Jquery Validator中遇到了一个有趣的问题。它始于在输入type =“ email”和输入type =“ password”上发生的相同问题-似乎任何输入BESIDES文本都会显示默认错误消息Please enter a value that is greater or equal to undefined。

因此，首先将输入类型从电子邮件更改为文本，但是我无法将密码类型更改为文本-我不想显示密码...

我不知道为什么会这样，或者不确定的变量是从哪里来的，甚至是如何找出来的。有什么建议？

下面的代码：

$.validator.addMethod("valid_pass", function(value, element, regexpr) {
                    return this.optional(element) || regexpr.test(value);
                }, "Your password must be between 8-15 characters and contain at least 1 number.");

$("#element1").validate({
                    errorPlacement: function(label, element) {
                         label.appendTo(element.parent('td').siblings('td'));
                    },
                    rules: {

                        password: { required: true, valid_pass: /^(?=.*\d).{8,15}$/ },
                        password2: { required: true, equalTo: "#password" }
                        },
                    messages: {

                        password: { required: "Create a password." },
                        password2: { 
                            required: "Re-enter your password.", 
                            equalTo: "Your passwords do not match." 
                        }
                    }
                });

和

<tr>
                            <td class="align-right"> Password: <a class="tooltip ml5" title="Password must be between 8-15 characters &amp; include at least 1 number">(?)</a></td>
                            <td><input type="password" id="password" name="password" maxlength="15" tabindex="9"/></td>
                        </tr>
                        <tr>
                            <td class="align-right"> Confirm password: </td>
                            <td><input type="password" name="password2" maxlength="15" tabindex="10"/>
                            </td>
                        </tr>
