var str = window.location.href;
var a = str.indexOf('success');

if(a >= 0){
  // means success exists
}else{
 // means success don't exists
}

Let's just hope that the domain isn't "get-successful.com". – h2ooooooo Dec 06 '13 at 11:42

You can use a regex of /\/success(\/|$)/ to test this:

if (/\/success(\/|$)/.test(window.location.href)) {
    console.log('Yep, it has success');
} else {
    console.log('Nope - no success');
}

This will accept /success/ anywhere in the string and would match:

http://xxxxxxxxx:8000/compare/387552/1/389688/1/success
http://xxxxxxxxx:8000/compare/387552/1/389688/success/1
http://xxxxxxxxx:8000/compare/387552/1/success/389688/1
http://xxxxxxxxx:8000/compare/success/387552/1/389688/1
http://xxxxxxxxx:8000/success/compare/387552/1/389688/1

If you only want to match success and the end of the URL, you should use /\/success\/?$/:

if (/\/success\/?$/.test(window.location.href)) {
    console.log('Yep, it has success');
} else {
    console.log('Nope - no success');
}

Which will only match:

http://xxxxxxxxx:8000/compare/387552/1/389688/1/success
http://xxxxxxxxx:8000/compare/387552/1/389688/1/success/

Try the Javascript function indexof

var url="http://xxxxxxxxx:8000/compare/387552/1/389688/1/success";
if(url.indexOf("success") > -1== true)
{
alert("present");
}
else
{
alert("not present");
}

That's all .
