The URLUtils.searchParams property is a URLSearchParams containing the query/search parameters of the URL.

Note: This feature is available in Web Workers.


object2 = object.searchParams;
object.searchParams = object2;


var anchor = document.createElement("a");
anchor.href = "https://developer.mozilla.org/en-US/search?q=URLUtils.searchParams&topic=api"
var searchParams = anchor.searchParams;

searchParams.has("topic") === true; // true
searchParams.get("topic") === "api"; // true
searchParams.getAll("topic"); // ["api"]
searchParams.get("foo") === ""; // true
searchParams.append("topic", "webdev");
searchParams.toString(); // "q=URLUtils.searchParams&topic=api&topic=webdev"
searchParams.toString(); // "q=URLUtils.searchParams"
anchor.href; // "https://developer.mozilla.org/en-US/search?q=URLUtils.searchParams"
