inputc.parentNode.removeChild(inputc);
alert("URL Copied.");
}

CodePudding user response：

Get url query string

const queryString = window.location.search;

Get code parameter value

const urlParams = new URLSearchParams(queryString);
const code = urlParams.get('code');

Save code parameter into clipboard

navigator.clipboard.writeText(code);
