How do I match string with URL in Jquery

I want to match a string in URL and redirect my page to other URL. Current URL is: http://example.com/?healing=f29c

Here is my code:

<script type="text/javascript">
        jQuery( document ).ready(function($) {

            var redirect_url = 'example.com/healing/';
            var current_url = window.location.href;
            if (current_url.indexOf('?healing=')){

                if(!current_url.match(redirect_url)){
                    window.location.replace(redirect_url);
                }
            return false;

            }
        });

        </script>

But I'am not getting the proper output. It start redirecting other pages to with or without having '?healing=' string in their URL.

And their is recurrence of URL to example http://example.com/product-category/aromafrequencies/example.com/healing/

Solution 1:

You have to do

<script type="text/javascript">
        jQuery( document ).ready(function($) {

            var redirect_url = 'example.com/healing/';
            var current_url = window.location.href;
            //please check condition
            if (current_url.indexOf('?healing=') > 0){

                if(!current_url.match(redirect_url)){
                    window.location.replace(redirect_url);
                }
            return false;

            }
        });

        </script>
