Fix state display none

[Rmh1978]

I corrected the display:none functions for when a country does not have states, it didnt work for years.

The function in redshop.js does work and display:none the State TR on change of country. But it does not hide id="div_state_txt" on initial load.

There is a issue in admin Addorder. If the BT country has states and you add shipping and choose a country that has no states redshop.js function also hides the BT state. I guess this effects only big international shop and happens rarely. Not a issue for me. My commits has not fixed or created this issue.

Hi @VanTrieuThanh

Your comment: "but select the Shipping address it not hide" Is related to the issue I described in the PR: "There is a issue in admin Addorder. If the BT country has states and you add shipping and choose a country that has no states redshop.js function also hides the BT state. I guess this effects only big international shop and happens rarely. Not a issue for me. My commits has not fixed or created this issue."

So i did not add the id="div_state_txt" in ST because then it would effect the BT user.

The rest of the comments are is also described in my PR because of the function: // Now let's hide state list by default in https://github.com/redCOMPONENT-COM/redSHOP/blob/develop/media/com_redshop/js/redshop.js does not hide the state list by default (on page load) and if there is a pre-selected country that has States then is should display state list. That is why i added this old core code more places: <script type="text/javascript" language="javascript"> if (document.getElementById('rs_state_state_code')) { if (document.getElementById('rs_state_state_code').options[1] == undefined) { document.getElementById('div_state_txt').style.display = 'none'; } } </script> This was not needed if the js check worked on initial load.

I have not added this code for the FE you commentet about because my FE dont work in my 3.0.3 test version. @NguyenBao10 is working on it, so i can test in FE as well.

My fixes have not broken, but enhanced the "state hide" some places but not all. The state hide function has not worked for years. I just hardcoded "display:none" on the state fields untill now.
