Detect HTTPS with JavaScript
https, javascript
Solution
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");
Problem
I am trying to find how can I detect with JavaScript if I am in a HTTP or HTTPS environment. I am calling an Ajax request so if I am in HTTPS and call HTTP Ajax then I get a 302 Moved Temporarily. I was thinking of getting the current `window.location.href` and do a string manipulation. What is the best way of detecting HTTPS using JavaScript?
