I am using jquery validator where I have added a method to validate a string which allow only numbers, spaces, plus sign, hyphen and brackets. Number is mandatory in the string but other charterer is optional.

My code for adding method in jquery validor:

jQuery.validator.addMethod( regex, function(value, element, regexp) {

        var re = new RegExp(regexp);

        return this.optional(element) || re.test(value);

    },

    Please check your input.

);

Following code for the rules:

rules: {

myfield: {

    required: true,

    regex: [0-9]+ // want to add regular expression but I wrote only for digit which works but do not understand how to reach at my requirements.

 },

}
