How to get query string values in JavaScript?

To get query string values in JavaScript, we can use the URLSearchParams constructor.

For instance, we write

const urlSearchParams = new URLSearchParams(window.location.search);
const params = Object.fromEntries(urlSearchParams.entries());

to create the URLSearchParams instance with the query string of the current URL.

window.location.search has the query string.

Then we get the returned query parameters in an iterable object with urlSearchParams.entries().

Finally, we covert the iterable object to a plain objectg with Object.fromEntries.

The keys of params has the query parameter keys and the values are the query parameter values.
