I'd like to run a js script if a user is visiting my site's root url. I am using this code:

<script type="text/javascript">
    if(location.pathname == "/") {
        window.open ('#107','_self',false);
    }
</script>

However /?foo=bar#hash will also run the script, since the pathname excludes the query string and location hash.

It currently behaves like this:

http://example/                  Root
              /?querystring      Root
              /#hash             Root
              /page              Not root

I want it to behave like this:

http://example/                  Root
              /?querystring      Not root
              /#hash             Not root
              /page              Not root

Any suggestions? Thanks.

Use window.location.href instead

You can concatenate the pathname, location.search and location.hash.

var fullPath = location.pathname + location.search + location.hash;
if(fullPath == "/") { /* whatever */ }

You can just test for all three ponents:

<script type="text/javascript">
    if(location.pathname == "/" && 
        location.hash.length <= 1 && 
        location.search.length <= 1) {
        window.open ('#107','_self',false);
    }
</script>
