exact url querystring param value replace with regex

Question

My URL is like :

I will have to replace vid value with "--notavailable--" So it should be:

I will have to use JS .replace() function(I have to use Regex).

There might be multiple params, should be exact param(XXXvid should NOT match)

Basically i have to pass solution to array like: ["regex","new param value"]

For example

  "https://www.example.com?vid=123124321524".replace(/[?|&]vid=\K([^&#]*)/,"--notavailable--")

Why is not working? EDIT: I realised it work with php not JS

I have tried lots of thing, still no luck. Thanks!

I guess javascript doesn't know \K, you could use:

var input = "https://www.example.com?vid=123124321524"
var output = input.replace(/([?&]vid=)[^&#]+/,"$1--notavailable--");
console.log(output);
