Jquery, .addMethod, undefined is not a function

Question

I've dived into javascript & jquery for the first time and I'm having a little difficulty wrapping my head around a problem.

fieldedit.php

<div class="editinput-body">

    <form id="edit_field_form"  class="form-horizontal" action="field.php" method="post">
        <div class="form-group">
            <input type="text" maxlength="10" class="form-control" name="field_name" id="edit_field" value="" validFieldName/>
        </div>
    </form>

</div>
<div class="editinput-footer">
    <button type="button" class="btn btn-default" onclick="closeEdit()">Close</button>
    <button type="button" class="btn btn-primary" id="editsubmit" onclick="submitEdit()">Edit</button>
</div>

editvalidator.js

function submitEdit() 
{    
    var formValidator = $('#edit_field_form').validate();
    var success = false;

    try 
    {
        formValidator.addMethod("validFieldName", function (value, element) 
        {
            return false;
        }, jQuery.validator.format("INVALID."));

        success = formValidator.form();
    }
    catch(err) 
    {
        alert("Error\n\n" + err);
    }
}

The formValidator.addMethod throws the error "TypeError: Undefined is not a function".

I'm using jquery-1.9.1.min.js and jquery.validate.min.

Any help would be greatly appreciated.

You're doing way more work than you need to, working against the validation library. (And why are you doing inline JS with jQuery?) I don't know the source of your error, but you should be able to avoid it entirely by implementing Validator correctly. — Evan Davis, Oct 13 '14 at 22:35
I need to be able to create my custom validation. Also, this is a project I'm just coming to work on towards its end. It is set up this way and I need to keep it as similar as possible. — Ben Y, Oct 13 '14 at 22:36
Your code is not quite right. Just follow the examples [here](http://stackoverflow.com/a/241202/594235) and [here](http://stackoverflow.com/tags/jquery-validate/info). — Sparky, Oct 14 '14 at 23:31
