Get query parameters

For years, we wrote rough regular expressions to get query string values, but those days are gone; now we can get query parameters through URLSearchParams API

We obtain the query parameters in a regular way without using URLSearchParams, as follows:

Function getQueryString (name) {var reg = new RegExp ("(^ | &)" + name + "= ([^ &] *) (& | $)"); var r = _ window.location.search.substr (1) .match (reg); return r? R [2]: null;}

After using URLSearchParams:

/ / suppose the query parameters in the address bar are as follows: "? post=1234&action=edit" var urlParams = new URLSearchParams_ (window.location.search); console.log (urlParams.has ('post')); / / trueconsole.log (urlParams.get (' action')); / / "edit" console.log (urlParams.getAll ('action')); / / ["edit"] console.log (urlParams.toString ()) / / "? post=1234&action=edit" console.log (urlParams.append ('active',' 1')); / / "? post=1234&action=edit&active=1" this article on "how to get query parameters for es6" ends here.
