jQuery validation plugin not working for checking special characters

I am trying to add a method to check for special characters at the same time it should allow spaces between words.

jQuery.validator.addMethod("specialChrs",function(element, value) {
        return this.optional(element) || /^[A-Za-z\d= ]+$/.test(value)
}, "Special Characters not permitted");

Below is my signup form.

$("#signupform").validate({

    rules: {
        name: {
            required: true,
            minlength: 3,
            specialChrs: true
        }
    },

    messages: {
        name: {
            required: "name is required",
            minlength: "name must be at least 3 characters"
        }
    }

The method is getting called but its not checking for the regular expression defined and also can anyone explain me what is return this.optional(element) here.

this.optinal(element) returns true if element is optional.

    jQuery.validator.addMethod("specialChrs", function (element, value) {
            return new RegExp('^[a-zA-Z0-9 ]+$').test(value)
        }, "Special Characters not permitted");


$("#signupform").validate({

    rules: {
        name: {
            required: true,
            minlength: 3,
            specialChrs: true
        }
    },

    messages: {
        name: {
            required: "name is required",
            minlength: "name must be at least 3 characters",
            specialChrs:"Special Characters not permitted",

        }
    }
