Title Body

I'm using the jQuery validation plugin and I want make use of a custom method which takes two the values entered into two different textboxes into account when deciding if the situation is valid. I know about add method and I've found an example ... jQuery.validator.addMethod("math", function(value, element, params) { return this.optional(element) || value == params[0] + params[1]; }, jQuery.format("Please enter the correct value for {0} + {1}")); ... which references two elements but I'm not clear how to write a rule which would make use of a method such as this ? To make it easier to discuss imagine that I want to make use of this example method and I've got a form that looks like this .. <form id="TOTALSFORM" name="TOTALSFORM"> <label for="LHSOPERAND">Input 1</label> <br /> <input type="text" name="LHSOPERAND" id="LHSOPERAND" class="required" /> <br /> <label for="RHSOPERAND">End</label> <br /> <input type="text" name="RHSOPERAND" id="RHSOPERAND" class="required" /> <label for="TOTAL">End</label> <br /> <input type="text" name="TOTAL" id="TOTAL" class="required" /> </form> I've got other rules that I apply like this : $("#OPTREASON").rules("add", { required: true, min: 0, messages: { required: "Required input", min: "Please select a Reason" } }); How can I do something similar to apply the example custom method shown so that 'TOTAL' is checked as being the sum of 'LHSOPERAND' and 'RHSOPERAND'.
