search not working due no indexcolname class

[peterdd]

On a shared server mod_autoindex does not put the classes into the th and td tags.

So no class indexcolname:

const nameColumns = Array.from(document.querySelectorAll('tbody .indexcolname'));

My workaround for current fancy-index:

const nameColumns = Array.from(document.querySelectorAll('tbody td:nth-child(1)'));
