Jquery Redirect Based on URL location

Question

This is what I'm trying to solve for...

1. Only if the URL explicitly contains /foldername/index.htm && /foldername/ on mydomain.com then redirect to http://www.example.com
2. Should the URL contain any URL parameter /foldername/index.htm?example it should not redirect
3. All other URLs should not redirect

This is my javascript which is incomplete, but is ultimately what I'm trying to solve for...

var locaz=""+window.location;
if (locaz.indexOf("mydomain.com") >= 0) {
    var relLoc = [
        ["/foldername/index.htm"],
        ["/foldername/"]
    ];
    window.location = "http://www.example.com"; 
}

This is for the purpose to manage a URL that some users are hitting based on a particular way like a bookmark. Without removing the page, we want to monitor how many people are hitting the page before we take further action.

Answer 1

Won't the page always be on the same domain, also if the url contains /foldername/pagename.htm won't it also already include /foldername ? So an && check there would be redundant.

Try the below code.

var path = window.location.pathname;

if  ( (path === '/foldername' || path === '/foldername/index.html') && !window.location.search ) {
    alert('should redirect');
} else {
    alert('should not redirect');
}

Answer 2

var url = window.location;
var regexDomain = /mydomain\.com\/[a-zA-Z0-9_\-]*\/[a-zA-Z0-9_\-]*[\/\.a-z]*$/    
if(regexDomain.test(url)) { 
  window.location = "http://www.example.com"; 
}

Answer 3

Familiarize with the location object. It provides pathname , search and hostname as attributes, sparing you the RegExp hassle (you'd most like get wrong anyways). You're looking for something along the lines of:

// no redirect if there is a query string
var redirect = !window.location.search 
  // only redirect if this is run on mydomain.com or on of its sub-domains
  && window.location.hostname.match(/(?:^|\.)mydomain\.com$/)
  // only redirect if path is /foldername/ or /foldername/index.html
  && (window.location.pathname === '/foldername/' || window.location.pathname === '/foldername/index.html');

if (redirect) {
  alert('boom');
}
