I know this question seems to be around a bit, but 90% of the answers point to a solution that is not working for me (indexof > -1).

```
if ( window.location.href.indexOf("product=3") > -1 || window.location.href.indexOf("product=2") > -1 ) {
    alert('success');
}else {
  alert('nothing');
}

```

The problem is that for product 30 this also alerts success.

Is there a simple solution that can detect an exact match in the url query string.

For example

mycoolsite.com/cart/?type=buynow&product=30

How can we check with javascript or jquery if the product equals 30?
