you can do it with a regex like :-

var url = "http://example.com/Apps/Visitor/visitscanner";
var dirName  = /\/\/.+?\/Apps\/(.+?)(?=\/)/g.exec(url)[1];

You can do this with regex if you want to match URLs like "http://example.com/Apps/Visitor/visitscanner/foo" or "http://example.com/Apps/Visitor"...

var url = "http://example.com/Apps/Visitor/visitscanner";
var match = /^(https?:\/\/)?example.com\/apps\/([^/]+)/i.exec(url);
var directory = match[2]; // get the second match group ("Visitor")

you could use split(), like:

var str = "example.com/Apps/Visitor/visitscanner";
var parts = str.split('/');
console.log( parts[parts.length - 2] ); //Visitor
