JavaScript redirect script if domain name does not match my word

Question

I want to put in my HTML/PHP a script for redirection if the website name does not match my word. I tried to use this code, but it doesn't work.

WITH REGEX

if (window.location.hostname !== 'myword.org'){
    window.top.location.href = 'http://redirecttomysite.org'; 
}

var website = window.location.hostname;
var internalLinkRegex = new RegExp('^((((http:\\/\\/|https:\\/\\/)(www\\.)?)?'
                                     + website
                                     + ')|(localhost:\\d{4})|(\\/.*))(\\/.*)?$', '');

WITHOUT REGEX

if (website !== 'myword.org'){
    window.top.location.href = 'http://redirecttomysite.org/forum'; 
}

Answer 1

try

if (website.indexOf('myword.org') == -1){
    window.top.location.href = 'http://redirecttomysite.org/forum'; 
}

Answer 2

simply as below

if (!(/stackoverflow\.com/i.test(location.hostname))){
...

similar behavior as an HTTP redirect

window.location.replace("http://stackoverflow.com");

similar behavior as clicking on a link

window.location.href = "http://stackoverflow.com";

Answer 3

if(window.location.href.indexOf("myword.org") == -1) {
       window.location = 'http://redirecttomysite.org';
    }
