Let index start at 1 (jQuery)

Hey all,

I am new to jQuery and I would like to know how I can let the index start at 1 instead of 0.

Here is my code:

$('.sort-options').on('change', function() {
            var ind = $(this).find('option:selected').index();
            $(".filter li:eq("+ind+")").find('a').click();
        });

What I am trying to do: I have a filter for a portfolio. I'm using isotope for this. The filter is in an ul on most screens, but on mobile I am showing a select dropdown. The code I am showing here is to make the filter work on the select. But this one has an extra (disabled option), so the index should start at 1 instead of 0 (atleast I think so).

From reading the document it seems like there isn't a way to internally set the index to 1. However, can't you use if statement to ignore case where index is 0?

In JavaScript/Jquery all lists/index are 0 based. You might want to use the :gt() Selector in Jquery, this might help. Here is the documentation:

I hope this helps, if not let us know what you come up with.
