Question

I have this HTML code:

Answer 1

I had the same problem and the solution in your case would be the following.

Plug-ins used:

• http://ajax.aspnetcdn.com/ajax/jquery.validate/1.13.1/jquery.validate.min.js
• http://ajax.aspnetcdn.com/ajax/jquery.validate/1.13.1/additional-methods.min.js

HTML:

JS:

$("#form").validate({
    // Rules for form validation
    rules:
    {
        "field1[]":
        {
            require_from_group: [1, ".pprice-group"]
        }
    },

    // Messages for form validation
    messages:
    {
        "field1[]":
        {
            require_from_group: 'At least {0} field required'
        }

    }
});
