jQuery validation of a form name with square brackets

问题

I have the following validation code for a text field but the 'field' below needs to be replaced with the name of the text field, which is created dynamically.

My problem is it has a square bracket in the name - options[483998]

How would I go about adding this to the code below as obviously if I do a direct replace of field with options[483998] it creates invalid coding.

jQuery("#product_addtocart_form").validate({
  rules: {
    field: {
      required: true,
      range: [100, 2540]
    }
  }
});

jQuery("#product_addtocart_form").validate({
  rules: {
    "options[483998]": {
      required: true,
      range: [100, 2540]
    }
  }
});

Just put it in quotes: "options[483998]"

Aren't you able to pull this off?

jQuery("#product_addtocart_form").validate({
  rules: {
    'options[483998]': {
      required: true,
      range: [100, 2540]
    }
  }
});

I've tried this as well, but my validation API code wont work with this technique.

"upload_images[]":
        {
            required: true, 
            accept:"jpg,png,jpeg"
        }

I'm working with a image upload input with multiple images, i need it to check if anything was selected before submitting the form. The other inputs work perfectly with the validation API.
