Accessing Form Elements Programmatically

    I need to access and update fields, such as quantity from a product field, from the Javascript function gform_product_total. I've tried doing it with something like:

    var qtyProduct = $("input[name=input_5.3]").val();

    However, this throws an error "$ is not a function".

    What is the right way of referencing form element values from within that function?

    Use jQuery instead of $

    That is the standard way of using jQuery in WordPress.

    var qtyProduct = jQuery("input[name=input_5_3]").val();

    Yeah, I had tried that, too, but there must be a syntax error with the element name reference "Syntax error, unrecognized expression: [name=input_5.3]".

    I'll keep digging. Thanks for your input, Kyle.

    Just a quick follow-up for others running into this issue:

    A quick search shows that the proper syntax should be:

    var qtyProduct = jQuery('input[name="input_5_3"]').val();

    Note the single and double quotation marks.
