js detect https

Question

Hi,

i am trying to find how can i "detect" width JavaScript if i am ih http or https environment

I am calling ajax request so if i am in https and call http ajax i get 302 Moved Temporarily

I was thinking of get the current window.location.href and do a strinh manipulation

Any suggestion is welcome.

Answer 1

You can use the non-standard

window.location.protocol 

In Firefox: MDC documentation

In IE, it seems to be

 document.location.protocol

MSDN documentation

I can't find reliable info on how this behaves on other browsers, but I expect they adhere to the quasi-standard of document.location.protocol.

Maybe the jQuery url plugin sorts this out without having to deal with cross-browser differences - I've never used it myself, but it looks promising:

jQuery.url.attr("protocol");

Answer 2

location.protocol works on both browsers
