Question

I thought I’d rewrite this and add a bit of context (more so it’ll be easier to explain to me) .

Basicaly I’m capturing the back/forward buttons with the popstate event like so :

 window.addEventListener("popstate", function(e) { 


     curstate = window.location.href ;

Then using a switch statement to determine what to do based on the new state :

     switch (curstate) {

        case 'http://mydomain.com/':

            navi('about', 200);
            break;



        case 'http://mydomain.com/resume':
            navi('resume', 200);
            break;
        };

    });

The problem comes when the state is mydomain.com/portfolio/-whatever-

I need a case : starts with mydomain.com/portfolio/(capture this bit of the uri) : then put the captured bit in a variable eg currentpage = capturedbitofuri .

Answer 1

// returns an array on success or null on failure
var match = /^mydomain\.com\/portfolio\/(.*)/.exec(str); 
if (match) {
   // match[1] contains the group (.*), which is everything after the prefix
   return match[1]; 
}
