JavaScript redirect script if domain name does not match my word

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';
}

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

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

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";

How can I add a parameter to my url, without reload the page?

I have this url http://localhost:1234/pag1
I want to be like below when I click on the div:
http://localhost:1234/pag1?fare=standar
and I have an onclick event function:
<div id="" onclick="addUrl();"> </div>
And the js code:
<script type="text/javascript">
function addUrl() {
var url = window.location.href;
window.location.hash = '?fare=standar';
};
</script>
This give me this result:
http://localhost:1234/pag1#?fare=standar
And I don't Know how to remove the (#). I only need to add the parameter to the url, without refresh the page.
Suggest me! Thank's.

Use window.history.pushState( {} , '', '?fare=standar' );
This should update the url without refresh.
You can also do a bit of reseach on pushState as the implementation can differ.

window.location.hash always put "#" in url
you can use to push paramter in url by using this function
function setGetParameter(paramName, paramValue)
{
var url = window.location.href;
if (url.indexOf(paramName + "=") >= 0)
{
var prefix = url.substring(0, url.indexOf(paramName));
var suffix = url.substring(url.indexOf(paramName));
suffix = suffix.substring(suffix.indexOf("=") + 1);
suffix = (suffix.indexOf("&") >= 0) ? suffix.substring(suffix.indexOf("&")) : "";
url = prefix + paramName + "=" + paramValue + suffix;
}
else
{
if (url.indexOf("?") < 0)
url += "?" + paramName + "=" + paramValue;
else
url += "&" + paramName + "=" + paramValue;
}
window.location.href = url;
}
i hope this will helpful to you

Try this
HTML
<div onclick="addUrl()"> </div>
Javascript
<script type="text/javascript">
function addUrl() {
var url = window.history.pushState( {} , '', '?fare=standar' );
</script>
Quick Explanation : When user clicks on div, URL will update without refreshing the page.
Hope this will work for you,
thank you :-).

Try this
var myURL = document.location;
document.location = myURL + "?a=parameter";
Or
location.hash = 'a=parameter'
Or without reloading the page
window.history.pushState("object or string", "Title", "new url");
Or without reloading the page
window.history.replaceState(null, null, "/another-new-url");

Why dont you use jQuery? I prepared sample like here in JsFiddle:
$("#clickableDiv").click(function(){
var url = "http://localhost:1234/pag1";
var parameter = "fare=standar";
$("#AppendUrl").text(url+ "?" + parameter);
});

check the url params in jquery and append something to the url

Is there a way to check the url params in jquery and append something to the url with refreshing the url.
So if current url path is:
http://someurl.com/test/
function myView() {
// if url does not have params of view='list' {
// update the url with http://someurl.com/test/&view=list
} else {
//dont update
}
}

var url= $(location).attr('href');
var val = url.indexOf('view');
if (val < 0) {
url += "?view=list";
window.location = url;
}

how to change in below url redirect script

I have a url redirect script that works very well, but i want some change in it.
when i redirect outgoing link then at the end of redirected url i got something like '#lcinside'
example
http://dl.dropbox.com/u/36139836/unknown.html?urlc=http://imgur.com/
goes to
http://imgur.com/#lcinside
but i want to put #lcinside before url start.
example
#lcinsidehttp://imgur.com
i want to put adf url redirect link instead of #lcinside.
how can i put #lcinside before url .
below is script.
please help me.
<script>
function gup(sName)
{
sName = sName.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var sRegEx = "[\\?&]" + sName + "=([^&#]*)";
var regEx = new RegExp(sRegEx);
var aResult = regEx.exec(window.location.href);
if(aResult == null)
{
return "";
}
else
{
return aResult[1];
}
}
if(gup("urlc") != "")
{
window.location = gup("urlc").replace("lcamp", "&") + "#lcinside";
}
</script>

If you are just trying to scrub the referrer, maybe you should use meta refresh
<meta http-equiv="refresh" content="1;url=http://imgur.com/#lcinside">

javascript, if current url withour request part

I want do something: if something type url address like: www.mydomain.com/search(without request part), I want do something with javascript, fill with the url like www.mydomain.com/search?search=car, but nothing happened in my code.
<script>
var curent_url = document.URL;
if(document.URL.indexOf("?") < 0){ //if(!document.URL.match(/\?/)){
//alert('ok');
document.URL = curent_url+'?search=car';
}
</script>

Instead of document.URL, check for an empty document.location.search:
if (document.location.search.length === 0) {
// empty query string... append your part to doc
document.location.href = document.location.href + "?search=car";
}
Examine the document.location object in your console to see what else it offers. There's usually no need to parse out document.URL or document.location.href directly.
console.dir(document.location);
