What is the best way to link to domain root?

问题

I'm setting up links and not sure which is the best way to link to the domain root should I do

<a href="/">home</a> or <a href="http://example.com">home</a> ?

is there a cooler way that I'm unaware of?

回答1:

Unless you have a specific reason you want to always use HTTP, use <a href="/">text</a>. You'll run into problems with SSL otherwise.

There is a cooler way to do it if you're loading scripts, and that is to load cross domain scripts in a protocol-neutral way, as such:

<script src="//example-cdn.com/scripts/jquery-latest-min.js"></script>

That way you avoid the HTTP mixed content warnings in IE.

回答2:

the simpler / variant is portable across domains, might be considered as an advantage.

回答3:

depends on the programming language you are using.. and the web-framework.. in plain html / would be your choice (portability)
