As you said that you want to use variable instead of directly using .replace(/&course_id=\d+/, ''), you can do it like below:-

Example:-

var re = new RegExp("&course_id=\\d+");
var newUrl="http://example.com/home.php?id=1&branch_id=4&course_id=5";
console.log(newUrl.replace(re, ''));

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

You can simply do that by using this code to remove &course_id=5:

var url = "http://example.com/home.php?id=1&branch_id=4&course_id=5";
url.replace(/([&\?]course_id=5*$|course_id=5&|[?&]course_id=5(?=#))/, '');

It will return you: http://example.com/home.php?id=1&branch_id=4
